Abstract
A series of depth maps image a scene. Each depth map includes a plurality of pixels, where each pixel defines a depth of a surface imaged by that pixel. A set of nonstatic pixels having a shallowest depth within the series of depth maps is identified. The position of this set of nonstatic pixels is mapped to a cursor position.
Claims16
A method of receiving user input, the method comprising:
- receiving a series of depth maps imaging a scene, each depth map including a plurality of pixels, each of the plurality of pixels defining a depth of a surface imaged by that pixel;
- identifying a set of nonstatic pixels having a shallowest depth within the series of depth maps;
- and
- mapping a position of the set of nonstatic pixels to a cursor position.

A computing device, comprising:
- a depth camera input configured to receive a series of depth maps imaging a scene, each depth map including a plurality of pixels, each of the plurality of pixels defining a depth of a surface imaged by that pixel;
- a logic subsystem configured to identify a set of nonstatic pixels having a shallowest depth within the series of depth maps and map a position of the set of nonstatic pixels to a cursor position;
- and
- a display output configured to output a user interface including a cursor at the cursor position.
