Abstract: A method, computing device and head-mounted display device for manipulating a virtual object displayed via a display device are disclosed. In one example, image data of a physical environment comprising physical features is received. A three dimensional model of at least a portion of the environment is generated. Candidate anchor features that each correspond to one of the physical features are extracted from the image data. User input is received that manipulates the virtual object as displayed within the environment. Based on the manipulation, a correspondence between a virtual anchor feature of the virtual object and a corresponding candidate anchor feature is identified. An indication of the corresponding candidate anchor feature at its corresponding physical feature within the environment is displayed to the user.

Abstract: Described is a system for collision detection and avoidance estimation using sub-region based optical flow. During operation, the system estimates time-to-contact (TTC) values for an obstacle in multiple regions-of-interest (ROI) in successive image frames as obtained from a monocular camera. Based on the TTC values, the system detects if there is an imminent obstacle. If there is an imminent obstacle, a path for avoiding the obstacle is determined based on the TTC values in the multiple ROI. Finally, a mobile platform is caused to move in the path as determined to avoid the obstacle.

Abstract: Various embodiments each include at least one of systems, methods, devices, and software for an augmented shared visual space for live mobile remote collaboration on physical tasks. One or more participants in location A can explore a scene in location B independently of one or more local participants current camera position in location B, and can communicate via spatial annotations that are immediately visible to all other participants in augmented reality.
