Abstract:
1. A method for changing the size of a background associated with a graphics-based user interface and output by a projector, the method comprising: displaying an arrow that operates as a background control tool, in response to user placement of a pointer at a border portion of the background, that allows a user to manually control the dimensions of a background to produce a background size that is less than a maximum image size allowed by the projector when the background video information is displayed without substantial keystone distortion, wherein the background defines a usable area that defines visual output limits and user input limits for the graphics-based user interface; receiving user input that moves the arrow and in response to the user moving the arrow, changing the dimensions of the background in a direction that the arrow is moved to the background size that is less than the maximum image size allowed by the projector when the background video information is displayed without substantial keystone distortion.
