Recognizing commands with a depth sensor
First Claim
Patent Images
1. A method for recognizing a command with a depth sensor, comprising:
- monitoring a tangible reference at a reference distance from a depth sensor;
maintaining a virtual reference approximately on calibrated three dimensional coordinates derived from said reference distance, said virtual reference intermediary to said tangible reference and said depth sensor;
maintaining a touch space between said virtual reference and a touch boundary separated from said virtual reference by a touch distance; and
recognizing a command when a predetermined object enters said touch space.

Abstract
Recognizing a command may include monitoring a tangible reference with a depth sensor, maintaining a virtual reference approximately on calibrated three dimensional coordinates of the tangible reference, maintaining a touch space adjacent the virtual reference, and recognizing a command when a predetermined object enters the touch space.

11. A system for recognizing a command, comprising:
-
a depth sensor positioned to determine a distance that a surface is away from said depth sensor; a processor in communication with said depth sensor; and said processor is programmed to; maintain a virtual reference intermediate to the depth sensor and surface based on continuous input received with said depth sensor; establish a touch space adjacent said virtual reference; and track a human hand moving into said touch space. - View Dependent Claims (12, 13, 14, 15)
