Abstract: Systems and approaches are provided for robustly detecting and tracking a user. Image data can be captured and processed to provide an estimated position and/or orientation of the user. Other sensor data, such as from an accelerometer and/or gyroscope, can be determined for a more robust estimation of the user's position and/or orientation. Multiple user detection processes and/or motion estimation approaches and their corresponding confidence levels can also be combined to determine a final estimated position and orientation of the user. The multiple user pose estimations and/or motion estimations can be combined via an approach such as probabilistic system modeling and maximum likelihood estimation.

Abstract: Systems and approaches are provided for tracking an object using multiple tracking processes. By combining multiple lightweight tracking processes, object tracking can be robust, use a limited amount of power, and enable a computing device to respond to input corresponding to the motion of the object in real time. The multiple tracking processes can be run in parallel to determine the position of the object by selecting the results of the best performing tracker under certain heuristics or combining the results of multiple tracking processes in various ways. Further, other sensor data of a computing device can be used to improve the results provided by one or more of the tracking processes.
