Abstract: Aspect methods and systems enable interaction with projected user interface through user input gestures performed on a mobile device. The mobile device may project the user interface image on an external surface, such as from a pico projector, and detect user input gestures performed by users. The mobile device may interpret the detected user input gestures, and change the projected user interface image in response to the interpreted user input gestures. User input gestures may be in the form of touch gestures performed on a touchscreen of the mobile device and/or in the form of hand gestures performed by turning, rotating and/or hoping the mobile device.

Abstract: Methods and devices enable rendering of graphic images at a minimum frame rate even when processing resource limitations and rendering processing may not support the minimum frame rate presentation. While graphics are being rendered, a processor of a computing device may monitor the achieved frame rate. If the frame rate falls below a minimum threshold, the processor may note a current speed or rate of movement of the image and begin rendering less computationally complex graphic items. Rendering of less computationally complex items continues until the processor notes that the speed of rendered items is less than the noted speed. At this point, normal graphical rendering may be recommenced. The aspects may be applied to more than one type of less computationally complex item or rendering format. The various aspects may be applied to a wide variety of animations and moving graphics, as well as scrolling text, webpages, etc.
