Abstract: In a system for moving, or dragging, a virtual reality environment, a user wearing a head mounted display (HMD) device may be at a first physical position in a physical space, corresponding to a first virtual position in the virtual environment.

The system may construct a three dimensional complex proxy surface based on the first and second virtual positions, and may move the virtual elements of the virtual environment along the proxy surface. This movement of the virtual environment may be perceived by the user as a move from the first virtual position to the second virtual position, although the user may remain at the first physical position within the physical space.

Abstract: A method for driving a dual-media display panel includes the following. Display data is obtained. A first driving signal for driving a transparent display panel of the dual-media display panel is generated in response to the display data. A display-unit grayscale value for the display data is obtained. The display-unit grayscale value is determined whether it falls within a grayscale value interval. When the display-unit grayscale value is less than a lower limit of the grayscale value interval, a driving signal adapted to enabling the light-shielding display panel to display a black color is used as the second driving signal. When the display-unit grayscale value is greater than an upper limit of the grayscale value interval, a driving signal adapted to enabling the light-shielding display panel to display a white color is used as the second driving signal.
