Patent ID: 8179366

Claim:
A method of controlling operation of a computer, comprising: sensing an actual position of a head of a user; producing, in a rendered scene of a program running on the computer, a virtual position in response to the actual position of the head of the user; producing, in the rendered scene, a virtual movement in response to a change in the actual position of the head of the user; simultaneously displaying an actual indicator visually representative of the head of the user and corresponding to the actual position of, and moving with, the head of the user and a virtual indicator visually representative of the head of the user and corresponding to the virtual position, and moving with the head of the user, the actual indicator and the virtual indicator being manipulable via user input to adjust a run-time scaling correlation between physical motion of the actual position and resulting control of the virtual position; during a configuration mode, receiving user input manually adjusting a position of the actual indicator of the head of the user relative to a position of the virtual indicator of the head of the user and/or the position of the virtual indicator relative to the position of the actual indicator; and adjusting the run-time scaling correlation between the virtual position and the actual position in response to adjustment of the position of the actual indicator and/or the position of the virtual indicator via the user input.
