Abstract: Systems and methods are described that include generating a virtual environment for display in a head-mounted display device. The virtual environment may include at least one three-dimensional virtual object having a plurality of volumetric zones configured to receive virtual contact. The method may also include detecting a plurality of inputs corresponding to a plurality of actions performed in the virtual environment on the at least one three-dimensional virtual object. Each action corresponds to a plurality of positions and orientations associated with at least one tracked input device. The method may include generating, for each action and while detecting the plurality of inputs, a plurality of prediction models and determining based on the plurality of prediction models in which of the plurality of volumetric zones the at least one tracked input device is predicted to virtually collide.

Abstract: An eye-tracking-based method and system of managing multi-screen view on a single display screen are disclosed. The method includes: when the display screen of a mobile terminal is under the multi-screen mode, determining the user's current eye gaze coordinates on the display screen using eye-tracking technology; determining whether a duration the user's gaze point stays within a specified range about the current gaze coordinates exceeds a preset gaze threshold, if exceeds, analyzing the user's eye movement information using the eye-tracking technology; when the eye movement information denotes an open-eye state, then determining whether the duration the gaze point stays within the specified range about the current gaze coordinates exceeds a preset full-screen threshold, if exceeds, display in full screen the split screen where the current gaze coordinates are located.
