摘要： Systems and methods for automated vehicle guidance based on coded lighting to enable automated vehicle following and/or regrouping. Systems use projectors to project temporal identifiers for space partitioned by pixel projections. Different space partition is associated with a different identifier. By using simple light sensors mounted on the vehicles, and decoding the sensed light signal, the vehicle can determine its precise location in the space relative to the coded light projector. This information may be used for precise vehicle guidance to enable vehicle following and/or regrouping. For vehicle following, the coded light projector is placed on a moving vehicle. For vehicle regrouping, the coded light projector may be placed on a ground or on a pole. Depending on the guidance precision requirements, the coded light precision may be adjusted by using light projectors with different resolutions.

摘要： Example implementations are directed to a system to generate keyframes describing the temperature output state of thermal output devices during the synchronous playback of video material. This additional haptic output channel augments the existing audio and video channels. Example implementations provide a manual keyframe authoring interface and an architecture for playing back video with a thermal output channel. Example implementations also involve an automatic keyframe generation method for thermal output accompanying a video, and provide a temperature profile function to enable rapid changing between temperature values for thermal output devices that use open-loop control.

摘要： A system to determine viewer attention to presented content. Markers are applied to a presentation. Head orientation information is received from a body mounted camera worn by a viewer and is used to determine a sequence of head orientations of the viewer. The sequence of head orientations is associated with an identifier of the viewer and a corresponding sequence of first time stamps. A sequence of images is captured by the body mounted camera worn by the viewer. The sequence of images is associated with an identifier of the viewer and the body mounted camera and a corresponding sequence of second time stamps. Respective members of the sequences of images and head orientations are associated, and the presentation content is identified by evaluating information from visible markers in the captured sequence of images. Viewer attention to different elements can then be determined.

摘要： A method of sharing documents is provided. The method includes capturing first image data associated with a document, detecting content of the document based on the captured first image data, capturing second image data associated with an object controlled by a user moved relative to the document, determining a relative position between the document and the object, combining a portion of the second image data with the first image data based on the determined relative position to generate a combined image signal that is displayed, and emphasizing a portion of the content in the displayed combined image signal, based on the relative position.

摘要： Computerized systems and computer-implemented methods that enable printing on a large solid surface, such as a floor, wall, or ceiling using mobile printer heads guided by coded light. In one implementation, a user points a projector onto the printing surface to project a sequence of images with a unique temporal identifier (ID) for each pixel, wherein different space partitions are associated with different pixel IDs. The mechanical transmissions of the conventional printers are replaced with the aforesaid coded light used in conjunction with small mobile printer heads equipped with light sensors, while the coded light is used to guide the printer heads' movements during the printing process.

摘要： Example implementations include a system and method for remotely controlling the motion of a robot. In example implementations, the user is presented with a display having video from a camera on the robot augmented with abstract sensor data, and facilitates the user to draw motion path commands directly on the camera view. Analysis of the scene for obstacles is performed, so that the drawing of commands is interactive, preventing the user from drawing impossible paths. The path sketch is then transformed into the coordinate system of the robot and used to generate commands that will move the robot to the desired location. Sensor data is also used to augment the camera view, in particular for highlighting dangers and obstacles.
