Customizable background sizes and controls for changing background size
First Claim
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 andin 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.

Abstract
This invention provides systems and methods that allow a user to change the size of a background used with a graphics-based user interface. This enables tailored background sizes based on user preference and allowable conditions, which are particularly useful with display devices having a large display area. By custom sizing a background to current conditions, a user may navigate an image among obstacles at a receiving surface and obstacles along a projection path between a projection lens and receiving surface. In addition, a user may customize the background size on a large LCD screen according to more suitable dimensions for an image used in the background or to a personal preference, thereby creating a personalized look and feel for the graphics-based user interface. One embodiment of the present invention defines a usable area for a graphics-based user interface according to the current size of the background. Changing the background size in this case also then changes the usable area for the graphics-based user interface.

2. A computer readable medium storing a graphics-based user interface displaying background video information using a projector as a display device, the computer readable medium comprising:
-
instructions for a background having an adaptable size and including background video information for display according to orthogonal image coordinates, the background video information for output by the projector having a maximum image size when the background video information is for display without substantial key stone distortion, wherein the background defines a usable area that defines visual output limits and user input limits for the graphics-based user interface; and instructions for a graphics control that includes an arrow, at a border portion of the background, that allows a user to manually control the dimensions of the background in a direction that the arrow is moved to produce a background size less than the maximum image size to avoid an obstacle at a receiving surface or an obstacle along a projection path between the projector and the receiving surface; and instructions for displaying the background size that is less than the maximum image size without substantial keystone distortion. - View Dependent Claims (3, 4, 5, 6)
