Disclosed herein are systems and methods for controlling a computing environment with one or more gestures by sizing a virtual screen centered on a user, and by adapting the response of the computing environment to gestures made by a user and modes of use exhibited by a user. The virtual screen may be sized using depth, aspects of the user such as height and/or user profile information such as age and ability. Modes of use by a user may also be considered in determining the size of the virtual screen and the control of the system, the modes being based on profile information and/or information from a capture device.
