DYNAMIC OBJECT TRACKING FOR USER INTERFACES

摘要

Systems and approaches provide for user interfaces (UIs) that are based on object tracking. For example, the object may be a user's head or face. As the user moves his head or face and/or tilts a computing device, the content displayed on the computing device will adapt to the user's perspective. The content may include three-dimensional (3D) graphical elements projected onto a two-dimensional (2D) plane and/or the graphical elements can be associated with textural shading, shadowing, or reflections that change according to user or device motion to give the user the impression that the user is interacting with the graphical elements in 3D environment. To enhance the user experience, a state of motion of the device can be determined and jitter and/or latency corresponding to the rendering of content can be altered so as to minimize or decrease jitter when the device is stationary and/or to decrease or minimize latency when the device is in motion.

1. A computing device, comprising:
one or more processors; a display screen; one or more cameras; one or more inertial sensors; and memory including instructions that, when executed by the one or more processors, cause the computing device to:
estimate a first position of a head of a user with respect to the computing device based at least in part upon one or more first images captured by the one or more cameras;display a first view of content on the display screen based at least in part upon the first position of the head of the user with respect to the computing device;obtain motion data, captured by the one or more inertial sensors, corresponding to motion of the computing device;determine, using the motion data, one or more performance parameters for tracking the head of the user, the one or more performance parameters controlling at least one of an amount of jitter or an amount of latency with respect to display of the content;estimate a second position of the head of the user with respect to the computing device based at least in part upon the one or more performance parameters, the first position of the head of the user with respect to the computing device, and one or more second images captured by the one or more cameras; anddisplay a second view of the content on the display screen based at least in part upon the second position of the head of the user with respect to the computing device.
