METHOD FOR CONTROLLING AN ALTERNATIVE USER INTERFACE IN A DEVICE

摘要

A method for controlling an alternative motion-based user interface in a device comprising a projector is provided. The method comprises receiving, at the device, an input comprising an instruction to switch from a previous user interface to the alternative user interface. The device then generates an image containing a plurality of selectable elements and a pointing element, and projects the image on a surface with the projector. The device detects a movement of the device, and updates the image to stabilize the plurality of selectable elements against the detected movement and to track the detected movement with the pointing element. The device projects the updated image on the surface, and selects one of the selectable elements based on a motion vector of the pointing element relative to the selectable elements. The device performs an action corresponding to the selected one of the selectable elements.
