This application is a continuation of and claims priority under 35 U.S.C. §120 to U.S. patent application Ser. No. 13/019,308, (U.S. Patent Publication No. US-2012-0194631-A1), filed Feb. 2, 2011.
Videoconferencing technology allows an individual to participate in a meeting or other event from a remote location. In conventional systems, the meeting room may include a display mechanism and one or more speakers which together present an audio-visual representation of the remote participant. The meeting room also includes one or more cameras and one or more microphones which together capture an audio-visual representation of one or more participants who are physically present in the meeting room. The local participants in the meeting room are referred to herein as hub participants because they define the core locus of the meeting. The remote participant is referred to as a satellite participant because he or she represents a person who is attending the meeting from a remote location.
Videoconferencing technology has enjoyed significant commercial success. Yet there are various instances in which this technology does not provide a fully satisfactory user experience. For example, consider the scenario in which the satellite participant directs a question or comment to a specific hub participant. It is often difficult for the hub participants to determine the target of the satellite participant's question or comment. This is because the visual representation of the satellite participant does not preserve some of the subtle communication cues by which people normally determine the directionality of a speaker's message.
For instance, the hub participants may notice changes in the satellite participant's head or eye gaze. But these cues are ambiguous in the visual representation of the satellite participant. When the satellite participant is looking straight ahead, each hub participant may perceive the satellite participant as looking directly at him or her, individually (an effect typically experienced when watching a TV newscaster). And when the satellite participant is looking to one side, each hub participant may perceive the satellite participant as looking to his or her left or right (but not aimed at anyone specifically).
The challenges noted above are presented by way of example, not limitation. Videoconferencing technology may suffer from yet other shortcomings. Further, other environments (besides videoconferencing environments) may experience similar difficulties to those set forth above.
A communication system is described herein for indicating a direction of awareness of a first entity, such as a satellite participant who maintains a virtual presence at a meeting. In one implementation, the communication system operates by receiving an explicit control input from at least one explicit input mechanism, and/or an implicit control input from at least one implicit input mechanism. The explicit control input reflects an express indication of the first entity's direction of awareness (as specified by the first entity), while the implicit control input reflects an inferred indication of the direction of awareness of the first entity. The communication system processes these control inputs to provide an explicit control output and/or an implicit control output, respectively. A mode selection module selects at least one of the explicit control output and the implicit control output based on at least one selection criterion, to generate a selected control output. An output mechanism then adjusts a position of an indicator based on the selected control output. In one environment, the indicator may assist a second entity (such as a hub participant) in determining the direction of awareness of the first entity.
The explicit input mechanisms can include any type of a knob, lever, key input mechanism, mouse device, touch-sensitive input mechanism, etc. The implicit input mechanisms can include any type of head movement detection mechanism, eye gaze detection mechanism, and so on.
In one implementation, the mode selection module is configured to select the implicit control output when explicit control has not been provided for a predetermined amount of time. Alternatively, or in addition, the mode selection module is configured to select the implicit control output when it is determined that the first entity has directed his or her attention at a target object for a predetermined amount of time. Alternatively, or in addition, the mode selection module can receive an express instruction from the satellite participant to use either the explicit control output or the implicit control output, or both. By virtue of the last-mentioned provision, a user can effectively disable either explicit control or implicit control, or both.
The communication system can rely on one or more different types of output mechanisms. In one case, an output mechanism corresponds to a mechanical pointer that is driven by a motor or other movement mechanism. In another case, the output mechanism corresponds to a solid-state display mechanism. In another case, the output mechanism corresponds to rotating display mechanism. In another case, the output mechanism corresponds to a display mechanism for presenting visual information that indicates the direction of awareness of the first entity, and so on. These examples are representative, rather than exhaustive.
By virtue of the communication system, the second entity (e.g., a hub participant) can more readily determine the person to whom the first entity (e.g., a satellite participant) is directing his or her questions, comments, gestures, and/or general attention (e.g., without necessarily asking a question).
The above approach can be manifested in various types of systems, components, methods, computer readable media, data structures, articles of manufacture, and so on.
This Summary is provided to introduce a selection of concepts in a simplified form; these concepts are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
The foregoing aspects and many of the attendant advantages of the disclosed subject matter will become more readily appreciated as they are better understood by reference to the following description when taken in conjunction with the following drawings, wherein:
The same numbers are used throughout the disclosure and figures to reference like components and features. Series 100 numbers refer to features originally found in
This disclosure is organized as follows. Section A describes an illustrative communication system for indicating a direction of awareness of a person to another person. Section B describes illustrative methods which explain one manner of operation of the communication system of Section A. Section C describes illustrative processing functionality that can be used to implement any aspect of the features described in Sections A and B.
As a preliminary matter, some of the figures describe concepts in the context of one or more structural components, variously referred to as functionality, modules, features, elements, etc. The various components shown in the figures can be implemented in any manner by any physical and tangible mechanisms (for instance, by software, hardware, firmware, etc., and/or any combination thereof). In one case, the illustrated separation of various components in the figures into distinct units may reflect the use of corresponding distinct physical and tangible components in an actual implementation. Alternatively, or in addition, any single component illustrated in the figures may be implemented by plural actual physical components. Alternatively, or in addition, the depiction of any two or more separate components in the figures may reflect different functions performed by a single actual physical component.
Other figures describe the concepts in flowchart form. In this form, certain operations are described as constituting distinct blocks performed in a certain order. Such implementations are illustrative and non-limiting. Certain blocks described herein can be grouped together and performed in a single operation, certain blocks can be broken apart into plural component blocks, and certain blocks can be performed in an order that differs from that which is illustrated herein (including a parallel manner of performing the blocks). The blocks shown in the flowcharts can be implemented in any manner by any physical and tangible mechanisms (for instance, by software, hardware, firmware, etc., and/or any combination thereof).
As to terminology, the phrase “configured to” encompasses any way that any kind of physical and tangible functionality can be constructed to perform an identified operation. The functionality can be configured to perform an operation using, for instance, software, hardware, firmware, etc., and/or any combination thereof.
The term “logic” encompasses any physical and tangible functionality for performing a task. For instance, each operation illustrated in the flowcharts corresponds to a logic component for performing that operation. An operation can be performed using, for instance, software, hardware, firmware, etc., and/or any combination thereof. When implemented by a computing system, a logic component represents an electrical component that is a physical part of the computing system, however implemented.
The following explanation may identify one or more features as “optional.” This type of statement is not to be interpreted as an exhaustive indication of features that may be considered optional; that is, other features can be considered as optional, although not expressly identified in the text. Similarly, the explanation may indicate that one or more features can be implemented in the plural (that is, by providing more than one of the features). This statement is not be interpreted as an exhaustive indication of features that can be duplicated. Finally, the terms “exemplary” and “illustrative” refer to one implementation among potentially many implementations.
A. Illustrative Communication System
In one environment, the meeting between the hub participants and the satellite participant takes place using videoconferencing functionality 102. The videoconferencing technology 102 includes at least one microphone and at least one video camera for capturing an audio-visual representation of the satellite participant. This equipment is provided at the remote location of the satellite participant. The videoconferencing technology 102 further includes at least one display mechanism and at least one speaker provided at the meeting location for presenting the audio-visual representation of the satellite participant. The videoconferencing technology 102 also includes at least one microphone and at least one video camera for capturing an audio-visual representation of the hub participants. This equipment is provided at the meeting location. The videoconferencing technology 102 further includes at least one display mechanism and at least one speaker provided at the remote location for presenting the audio-visual representation of the hub participants to the satellite participant. By virtue of this equipment, the satellite participant can take part in the meeting in a virtual fashion.
Many examples will be set forth below in which a single satellite participant interacts with two or more hub participants. However, these examples are representative, not exhaustive. In another environment, for instance, two or more satellite participants interact with two or more hub participants. The satellite participants can interact with the communication system 100 from the same remote location or different respective locations. In this context, the communication system 100 can provide an independent indication of the direction of awareness for each satellite participant. Moreover, in this scenario, the communication system 100 can provide an output mechanism at the remote site(s) which determines the direction of awareness of any hub participant. In other words, for example, the communication system 100 can provide a first indicator which indicates the direction of awareness of a satellite participant (for the benefit of the hub participants), and a second indicator which indicates the direction of awareness of a hub participant (for the benefit of the satellite participants).
In another environment, the meeting room can include a single hub participant. This means that the satellite participant cannot possibly be looking at several hub participants; nevertheless, the communication system 100 can help the single hub participant determine what object the satellite participant is looking at. For example, the communication system 100 can indicate whether the satellite participant is looking at the single hub participant, a whiteboard, a collaborative workspace, or some another object.
In another environment, the satellite participant is not physically remote from the hub participants, but may, in fact, be present in the same meeting room as the hub participants. In this situation, the communication system 100 can help disambiguate the direction of awareness of the satellite participant (where, in this case, the term “satellite” no longer connotes remoteness). For example, the satellite participant may wish to provide such a cue because he or she is disabled and cannot readily engage in typical communication cues, although he or she is physically present in the same room with the hub participants.
In another implementation, the communication system 100 can provide an indication of the direction of awareness of the satellite participant in some environment other than a meeting room. For example, the satellite participant may be controlling a robot proxy of any type in any environment, e.g., to perform a task in a dangerous environment (to cite merely one example). The satellite participant can use the communication system 100 to convey his or her direction of awareness to individuals in the vicinity of the robot proxy.
In another implementation, the communication system 100 can provide an indication of the direction of awareness in a context in which one or more hub participants correspond to non-human agents of any type.
Still further applications of the principles described herein are possible. However, as stated above, the following explanation will emphasize the representative scenario in which a single satellite participant interacts with plural hub participants.
The communication system 100 includes an attention determination module 104. The attention determination module 104 receives control input from one or more input mechanisms 106 (referred to in the singular for brevity below). The control input provides information which has a bearing on the direction of awareness of the satellite participant. In other words, the control input provides information which indicates what object(s) the satellite participant is looking at. Based on this information, the attention determination module 104 generates a selected control output, which it sends to one or more output mechanisms 108. The output mechanisms 108 adjust a position of at least one indicator to convey the direction of awareness of the satellite participant. Each of these components of the communication system 100 will be set forth in turn below.
Starting with the input mechanisms 106, the input mechanisms 106 can include one or more explicit input mechanisms 110 and/or one or more implicit input mechanisms 112. The explicit input mechanisms 110 includes mechanisms by which the satellite participant expressly (e.g., manually) indicates his or her direction of awareness. For example, the explicit input mechanisms 110 can include knobs, joy sticks, key input mechanisms, mouse devices, touch-sensitive input mechanisms, and so on. Additional details regarding one manner in which a satellite participant may convey his or her direction of awareness will be set forth in greater detail below. The explicit input mechanisms 110 provide an explicit control input to the attention determination module 104.
The implicit input mechanisms 112 include mechanisms which produce information from which the direction of attention of the satellite participant can be inferred, e.g., without the satellite participant being asked to expressly indicate that information. For example, one type of implicit input mechanism includes a head position determination mechanism. This input mechanism determines the position and orientation of the satellite participant's head and/or other body parts. Another type of implicit input mechanism includes an eye gaze detection mechanism. This input mechanism determines the position of the satellite participant's eyes, e.g., by detecting the reflection of infrared light from the corneas of the eyes. The implicit input mechanisms 112 provide an implicit control input to the attention determination module 104. The attention determination module 104 can use this implicit control input to determine what object(s) lie within the presumed field of view of the satellite participant.
The implicit input mechanisms 112 can also receive other cues which have a bearing on the direction of attention of the satellite participant's awareness. As will be described below, this additional information allows the attention determination module 104 to either bolster or detract from its conclusion as to the direction of the participant's awareness. For example, the implicit input mechanisms 112 can receive information regarding events that take place in the course of the meeting. For example, one such event may indicate that a hub participant has started speaking. Another event may indicate that someone has opened up a document on a collaborative workspace or approached a whiteboard, etc.
The attention determination module 104 includes an explicit control processing module 114 for processing the explicit control input from the explicit input mechanisms 110. The explicit control processing module 114 generates a conclusion from the explicit control input regarding the direction of awareness of the satellite participant. This operation may involve determining target object(s) of interest that correspond to a position that is manually specified by the satellite position. The operation then involves determining a position that the indicator (of an output mechanism) can be moved to so as to point to the target object(s). In one implementation, these determinations can be performed based on any type of mapping information which translates the explicit control input to an indicator position. The output of the explicit control processing module 114 is referred to herein as an explicit control output.
In addition, or alternatively, the attention determination module 104 includes an implicit control processing module 116. The implicit control processing module 116 processes the implicit control input from the implicit input mechanisms 112. Like its explicit counterpart, the implicit control processing module 116 generates a conclusion from the implicit control input as to what the satellite participant is looking at, referred to as an implicit control output herein. In one implementation, this operation may involve determining a field of view that is defined by the satellite participant's head position and orientation, and/or the direction of the participant's gaze. The implicit control processing module 116 can then determine the target object(s) within this field of view. The operation then involves determining a position that the indicator (of the output mechanism) can be moved to so as to point to the target object(s).
The implicit control processing module 116 can also take into consideration other events that have a bearing on the satellite participant's head position and/or direction of gaze. The events can be used to help confirm (or detract from) a conclusion as to what object the satellite participant is looking at. For example, the implicit control processing module 116 can draw a tentative conclusion based on a control input from a head detection mechanism that the satellite participant has turned his or her gaze towards a particular hub participant. Further assume the implicit control processing module 116 determines that the hub participant started speaking just before the satellite participant turned his or her head. This confluence of events makes it more likely that the satellite participant did in fact turn his or her head towards the particular hub individual in question.
A mode selection module 118 receives the explicit control output from the explicit control processing module 114 and the implicit control output from the implicit processing module 116. Based on at least one selection criterion, the mode selection module 118 chooses which control output is to govern the output mechanisms 108. In one case, the mode selection module 118 determines that the explicit control output is to govern the output mechanisms 108. In another case, the mode selection module 118 determines that the implicit control output is to govern the output mechanisms 108. In another case, the mode selection module 118 determines that some combination of the explicit control output and the implicit control output is to govern the output mechanisms 108. In another case, the mode selection module 118 determines that neither the explicit control output nor the implicit control output is to govern the output mechanisms 108
For example, in one scenario, the mode selection module 118 is configured to use the explicit control output when the satellite participant is in fact operating the explicit input mechanisms 110 to expressly define his or her direction of awareness. In this case, the mode selection module 118 switches from the explicit control output to the implicit control output a predetermined amount of time after the satellite participant stops interacting with the explicit input mechanisms 110.
In another scenario, the mode selection module 118 is configured to use the implicit control output when that control output indicates that the satellite participant has directed his or gaze towards a particular person or object for more than a predetermined time.
In another scenario, the mode selection module 118 chooses the explicit control output or the implicit control output (or both or neither) depending on an express instruction provided by the satellite participant (or another agent). Through the last-mentioned provision, a user can effectively disable either explicit control or implicit control, or both. Still additional selection criteria can be used to select from among the explicit control output and the implicit control output.
In other implementations, the communication system 100 can be constructed using just the explicit input mechanism(s) 110 (without the implicit input mechanisms(s) 112), or just the implicit input mechanism(s) 112 (without the explicit input mechanism(s) 110). If just the explicit input mechanism(s) 110 are used, the mode selection module 118 can be used to control the activation/deactivation of the explicit input mechanism(s) 110; similarly, if just the implicit input mechanism(s) 112 are used, the mode selection module 118 can be used to control the activation/deactivation of the implicit input mechanism(s) 112. Alternatively, the communication system 100 can entirely eliminate the mode selection module 118.
The mode selection module 118 can provide various damping behavior to exclude transitional and ephemeral targets of awareness. For example, the mode selection module 118 can generate a conclusion that the satellite participant is looking at a particular object only if the satellite participant trains his or her attention on that object in a consistent manner for at least a predetermined amount of time. The output of the mode selection module 118 is referred to herein as a selected control output.
The output mechanisms 108 use one or more techniques to convey the direction of awareness of the satellite participant based on the selected control output. A first category of output mechanisms corresponds to mechanical vane mechanisms 120. Here, the communication system 100 uses the selected control output to adjust the position of a mechanical pointer. A second category of output mechanisms corresponds to solid-state vane mechanisms 122. Here, the communication system 100 uses the selected control output to illuminate selected elements in an array of solid-state indictors (e.g., LEDS or the like). A third category of output mechanisms corresponds to display-related vane mechanisms 124. Here, the communication system 100 uses the selected control output to provide visual information on a display mechanism which conveys the direction of awareness. These categories are representative, rather than exhaustive.
One or more coupling mechanisms 206 can be used to connect together the hub conferencing devices 202 with the satellite conferencing devices 204. The coupling mechanisms 206 can correspond to any type of local area network (LAN), any type of wide area network (WAN) (e.g., the Internet), any type of point-to-point connections, and so on, or any combination thereof.
The functions described in connection with
Now advancing to
The meeting room 300 also includes a video camera 312 for capturing a video representation of the three hub participants (302, 304, 306). Although not shown, the meeting room 300 can also include one or more microphones which capture audio information which originates from the hub participants (302, 304, 306). Although not shown, the satellite participant has a counterpart display mechanism and speaker(s) for together presenting an audio-visual presentation of the meeting room 300, including the three hub participants. (
Finally, the meeting room 300 may also include an output mechanism that includes a motor 314 (such as a servo motor or other movement mechanism) and a mechanical pointer 316. The motor 314 drives the mechanical pointer 316 based on the selected control output provided by the attention determination module 104. In operation, the attention determination module 104 drives the mechanical pointer 316 to a position so that it points at a particular hub participant 302. This is based on the conclusion, made by the attention determination module 104, that the satellite participant is looking at this particular hub participant 302. Again, that determination can be made based on any combination of explicit control input and implicit control input.
The mechanical pointer 316 in this case is a brightly-colored elongate member, about five inches long, that rotates around a base stem of the display mechanism 308 (in as quiet a manner as possible). This is one of many examples. The mechanical pointer 316 can have any shape, size, color, and functionality. Further, the mechanical pointer 316 can be provided at any location within the meeting room 300. Or the indicator can include multiple mechanical pointers (not shown). Further, the mechanical pointer 316 can have any relationship with respect to other equipment provided in the meeting room 300. For instance, in one example, the base member of the display mechanism 308 can house the motor 314 which drives the mechanical pointer 316, but this is merely one option among many.
In the examples set forth above, the hub participants (302, 304, 306) can make note of the position of the mechanical pointer 316 as they converse with the satellite participant. Using this approach, the hub participants (302, 304, 306) can be better informed as to the person(s) to whom the satellite participant is directing questions, comments, and/or gestures. Or, in some instances, the satellite participant may be just directing his or her attention towards a particular person without otherwise communicating with that person. For reasons set forth above, this awareness information cannot be readily determined solely based on the visual representation 310 of the satellite participant.
Furthermore, in the case in which explicit control input is provided, the satellite participant is now free to look straight ahead into the video camera, rather shifting his head to telegraph his direction of awareness. In some circumstances, this may provide better user experience for both the satellite participant and the hub participants. Namely, because the satellite participant is looking straight ahead into the video camera, the hub participant to which the indicator is pointed may perceive the satellite participant as looking directly at him or her.
Although not shown in
With reference to
In one manner of use, assume that the communication system 100 can present an audio-visual representation of the satellite participant on the computing device 1602. Further assume that one of the hub participants is holding the computing device 1602. Other hub participants may be positioned in the meeting room so that they can view and listen to the same audio-visual representation presented by the computing device 1602. But in another implementation, each participant may interact with his or her own computing device (not shown) which presents an audio-visual representation of the satellite participant.
The computing device 1602 can use any type of indicator described above to indicate the direction of awareness of the satellite participant to one or more hub participants. In the example shown in
Further assume that the computing device 1602 includes one or more movement determination mechanisms 1606 (e.g., within its housing), such as an accelerometer, an n-axis gyroscopic device (e.g., a three-axis gyroscopic device), and so on. The movement determination mechanism(s) 1606 determine changes in the position and/or orientation of the computing device 1602 to provide movement information. A position adjustment module 1608 receives the movement information from the movement determination mechanism(s) 1606 and the selected control output from the attention determination module 104. Based thereon, the position adjustment module 1608 produces a position control output. The position control output adjusts the position of the indicator 1604 so that it remains pointed at the target object, even though the position and/or orientation of the computing device 1602 may change.
For example, assume that, as shown in the bottom part of
In the case in which plural hub participants operate plural respective computing devices, each computing device can include an indicator which points at the common target object, and which furthermore maintains a directional lock on the common target object during movement of the computing device.
Although not shown, any implementation of the output mechanisms 108 can combine two or more of the types of output mechanisms described above. For instance, one implementation can use both a mechanical pointer and on-screen visual information to convey the direction of awareness of the satellite participant.
Further, as described above, the environment 1700 can include one or more explicit input mechanisms 110 by which the satellite participant 1702 can expressly designate his or her direction of awareness. The satellite participant 1702 can perform this function by expressly designating a portion 1706 of a visual representation of the meeting room provided on the display mechanism 1704. The environment 1700 can also include one or more implicit input mechanisms 112 which can infer the direction of awareness of the satellite participant 1702. For instance, the implicit input mechanisms 112 may include a head tracking mechanism which determines a position and orientation of the satellite participant's head, e.g., based on an image representation of the satellite participant's head captured by one or more cameras of any type(s), etc. The implicit input mechanisms 112 may also include an eye gaze determination mechanism which determines a direction of gaze of the satellite participant 1702, e.g., based on an image representation of the satellite participant's eyes captured by one or more cameras of any type(s), etc. The implicit control processing module 116 can use this implicitly-determined position information to cast a frustum out from the head of the satellite participant 1702. That frustum will intersect a plane defined by the screen of the display mechanism 1704, thus defining a particular portion 1706 of the visual representation of the meeting room which corresponds to the satellite participant's presumed focus of interest.
The attention determination module 104 can use various techniques to translate an indication of direction of awareness to an indicator position. In a first approach, the video representation of the meeting room encompasses the indicator, enabling the satellite participant to see the indicator on his or her display mechanism 1704. The satellite participant can then use the visual feedback provided by the display mechanism 1704 to manually move the indicator to a desired position, e.g., so that it points to a target of interest. The satellite participant can perform this task using any of the explicit input mechanism(s) 110.
In a second implementation, the attention determination module 104 may predefine a set of possible positions in the meeting room where the hub participants may generally sit, e.g., corresponding to positions around a table or the like. Upon the start of a meeting, each hub participant can then manually indicate where he or she is located within the meeting room. The attention determination module 104 can include mapping information which maps an explicit or implicit designation of a target object with an indication of a position within the meeting room, and which also maps an indication of the position within the meeting room with a pointer position. Hence, when the satellite participant identifies a particular hub participant, the control modules (114, 116) are able to generate a control output which moves the indicator to the appropriate position.
In a third implementation, the communication system 100 can automatically detect the position of the hub participants in the room, e.g., based on image information and/or audio information. For example, at the start of a meeting, the communication system 100 can determine the locations of the hub participants in an image of the meeting room, where that image may contain reference points which establish a frame of reference. Alternatively, or in addition, the communication system 100 can detect the locations of the hub participants in the meeting room based on the directionality of voices which originate from the hub participants. The control modules (114, 116) can leverage this information in the manner stated above for the second implementation, e.g., using mapping information to translate an explicit and/or implicit designation of a target object to a pointer position.
The above three implementations are representative, not exhaustive.
In the particular case of the moveable computing device 1602 of
B. Illustrative Processes
In block 2002, the communication system 100 receives control input from one or more explicit input mechanisms 110 and/or one or more implicit input mechanisms 112.
In block 2004, the mode selection module 118 of the communication system 100 determines whether explicit and/or implicit control (or neither) is appropriate in view of at least one selection criterion. For example, the mode selection module 118 can select implicit control when there is an absence of explicit control for more than a predetermined time. Alternatively, or in addition, the mode selection module 118 can select implicit control when it is appears that the satellite participant is training his or her attention on a target object in the meeting room for more than a predetermined amount of time, and so on. Alternatively, or in addition, the mode selection module 118 can select explicit control and/or implicit control (or neither) based on an express instruction by the satellite participant (and/or any other agent).
In block 2006, the communication system 100 can use the selected control output (determined in block 2004) to drive an indicator provided by an output mechanism. The indicator can be implemented as any of a mechanical pointer, a solid-state display mechanism, a rotating display mechanism, visual information presented on a display mechanism, and so on, or any combination thereof.
C. Representative Processing Functionality
The processing functionality 2100 can include volatile and non-volatile memory, such as RAM 2102 and ROM 2104, as well as one or more processing devices 2106 (e.g., one or more CPUs, and/or one or more GPUs, etc.). The processing functionality 2100 also optionally includes various media devices 2108, such as a hard disk module, an optical disk module, and so forth. The processing functionality 2100 can perform various operations identified above when the processing device(s) 2106 executes instructions that are maintained by memory (e.g., RAM 2102, ROM 2104, or elsewhere).
More generally, instructions and other information can be stored on any computer readable medium 2110, including, but not limited to, static memory storage devices, magnetic storage devices, optical storage devices, and so on. The term computer readable medium also encompasses plural storage devices. In all cases, the computer readable medium 2110 represents some form of physical and tangible entity.
The processing functionality 2100 also includes an input/output module 2112 for receiving various inputs (via input modules 2114), and for providing various outputs (via output modules). One particular output mechanism may include a presentation module 2116 and an associated graphical user interface (GUI) 2118. The processing functionality 2100 can also include one or more network interfaces 2120 for exchanging data with other devices via one or more communication conduits 2122. One or more communication buses 2124 communicatively couple the above-described components together.
