Embodiment Construction

[0015] This disclosure relates to the fact that users can use natural gestures (e.g., hand gestures) without having to hold any motion detection controls (e.g., accelerometers, gyroscopes, etc.) or wear any specific markers (e.g., retroreflectors). Move) to control the virtual desktop. Specifically, the user is efficiently and accurately modeled and tracked using a depth camera or other source for obtaining depth information. The user's position and orientation in world space is used as a basis for establishing an interaction zone that has a position and orientation that tracks the user's position and orientation. The user can move his hands or other body parts within the interaction zone to control the position of virtual objects (eg, cursors) in the virtual desktop.

[0016] figure 1 A non-limiting example of object tracking system 10 is shown. in particular, figure 1 A gaming system 12 is shown that can be used to play various different games, play one or more different...

Abstract

A computing system includes a depth image analysis module to track a world-space pose of a human in a fixed, world-space coordinate system. The computing system further includes an interaction module to establish a virtual interaction zone with a movable, interface-space coordinate system that tracks the human and moves relative to the fixed, world-space coordinate system. The computing system also includes a transformation module to transform a position defined in the fixed, world-space coordinate system to a position defined in the movable, interface-space coordinate system.

Description

Background technique [0001] The desktop metaphor is widely used in attempts to make computing systems more user-friendly. Although the desktop metaphor has proven to be easier to use than the command-line interface, some users still get frustrated with mice, trackballs, trackpads, and other input devices. Contents of the invention [0002] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of the invention. [0003] According to some aspects of the present disclosure, a computing system is configured to provide a virtual desktop that can be manipulated using natural gestu...
