Method for controlling an alternative user interface in a device

A method for controlling an alternative motion-based user interface in a device comprising a camera and a display, the method comprising:

• receiving, at the device, an input comprising an instruction to switch from a previous user interface to the alternative user interface;
• capturing, with the camera, a video feed of a surface;
• generating, by the device, an image containing a plurality of selectable elements and a pointing element;
• presenting the image on the display overlaid on the video feed;
• detecting, by the device, movement of the device;
• updating, by the device, the image to stabilize the plurality of selectable elements against the detected movement and to track the detected movement with the pointing element;
• presenting the updated image on the display overlaid on the video feed;
• selecting, by the device, one of the selectable elements based on a motion vector of the pointing element relative to the selectable elements;
• performing an action at the device corresponding to the selected one of the selectable elements.

A device, comprising:

• an image output apparatus;
• a processor connected to the image output apparatus and operated to:
• receive an input comprising an instruction to switch from a previous user interface to an alternative user interface;
• generate an image containing a plurality of selectable elements and a pointing element;
• control the image output apparatus to output the image;
• detect a movement of the device;
• update the image to stabilize the plurality of selectable elements against the detected movement and to track the detected movement with the pointing element;
• control the image output apparatus to output the updated image;
• select one of the selectable elements based on a motion vector of the pointing element relative to the selectable elements;
• perform an action corresponding to the selected one of the selectable elements.
