摘要： A mobile communications device for performing localization and mapping is disclosed, comprising a sensor operative to capture sensor data of its local environment, and operative to derive point-cloud data from the sensor data, which represents structural features of the local environment, determine a pose of the mobile communications device relative to a point-cloud map representing the local environment, derive a concealed representation of the point-cloud data, by applying a current linear transformation to the point-cloud data, and transmit the concealed representation of the point-cloud data to a map server. The current linear transformation is a shared secret, or is derivable from a shared secret, which shared secret is available to a group of mobile communications devices comprising the mobile communications device. Also disclosed are the map sever and a trusted server.

摘要： A controller for controlling wireless command transmission to a robotic device is presented, wherein the robotic device is capable of selectively performing a collaborative task with another entity and a non-collaborative task. The controller is configured to identify if a task to be performed by the robotic device is a collaborative or non-collaborative task, and to trigger a setting of at least one transmission parameter for a wireless command transmission to have the robotic device perform the task, wherein the setting is dependent on whether the task to be performed is a collaborative or a non-collaborative task.

摘要： A method is disclosed for generating a haptic model including at least one virtual object which can be presented using both a visual display device and a haptic device to a user. Information of at least one candidate virtual object is obtained, the candidate virtual object including both a haptic representation and a visual representation. For each of the at least one candidate virtual object, reachability data, indicating whether the candidate virtual object is reachable for the user is determined. For each of the at least one candidate virtual object, visibility data, indicating whether the candidate virtual object is visible for the user is determined. A haptic model is generated selectively including at least one candidate virtual object, the inclusion of each candidate virtual object being based on its respective reachability and visibility data. The haptic model is provided to be rendered.

摘要： A portable electronic device is used with a mixed reality (MR) headset. The MR headset includes a lens and a holder that retains the portable electronic device in a defined orientation relative to the lens. The portable electronic device includes a camera, a display device, and a processor. The camera outputs video frames and is arranged to view the lens. The display device is arranged to display information that is projected on the lens for reflection directly or indirectly toward the user's eyes and the camera. The processor performs operations that include processing the video frames from the camera to identify locations of at least one real-world feature, displaying information on the display device, and controlling at least one of the processing of the video frames and the displaying of the information on the display device to at least partially reduce occurrence in the video frames of the displayed information.

摘要： An input device (100) for a computing device (150) is provided, such as a data glove. The input device (100) comprises motion sensor(s) (103) configured to be worn on a fingertip or fingertips of a user, and actuator(s) (104, 114) configured to restrict motion of the fingertip(s) to be within a three-dimensional shape. The input device (100) is operative to track a position of the fingertip(s) using the motion sensor(s) (103), provide the tracked position as user input to the computing device (150), determine whether the computing device requires user input from the fingertip to be within the three-dimensional shape, and in response thereto, activate the actuator(s) (104, 114) configured to restrict motion of the fingertip(s) to be within the three-dimensional shape if the computing device (150) requires user input from the fingertip(s) to be within the three-dimensional shape. Thereby, the user is prevented from moving his/her fingertip(s) to a position in space which renders user input which is not accepted by the computing device (150) receiving the user input.
