Abstract
A method for adjusting image geometry in a system having a video display monitor, an input device and an input device pointer visually representing the position of the input device on the video display monitor comprises the steps of generating an image geometry adjustment screen, hiding the input device pointer and generating a simulated input device pointer, using positional information received to accordingly adjust the image geometry, and restoring the input device pointer to the image geometry adjustment screen.

A method for adjusting image geometry in a system having a video display monitor, an input device, and an input device pointer visually representing the position of the input device on the video display monitor, the method comprising the steps of:
- generating an image geometry adjustment screen on the video display monitor, the image geometry adjustment screen including at least one image geometry adjustment object engageable by appropriate operation of the input device;
- hiding the input device pointer and generating a simulated input device pointer that indicates changing geometry of the image geometry adjustment screen;
- receiving positional information from the input device;
- using the positional information to adjust the image geometry, whereby the simulated input device pointer is moved accordingly;
- and
- restoring the input device pointer on the image geometry adjustment screen.
A computer-readable medium comprising program instructions for adjusting image geometry in a system having a video display monitor, an input device, and an input device pointer visually representing the position of the input device on the video display monitor by performing the steps of:
- generating an image geometry adjustment screen on the video display monitor, the image geometry adjustment screen including at least one image geometry adjustment object engageable by appropriate operation of the input device;
- hiding the input device pointer and generating a simulated input device pointer that indicates changing geometry of the image geometry adjustment screen;
- receiving positional information from the input device;
- using the positional information to adjust the image geometry, whereby the simulated input device pointer is moved accordingly;
- and
- restoring the input device pointer on the image geometry adjustment screen.
An apparatus for adjusting image geometry in a computer system having a video display monitor and an input device, the apparatus comprising:
- a memory;
- input device pointer means stored in the memory for generating an input device pointer visually representing the position of the input device on the video display monitor, the image geometry adjustment screen including at least one image geometry adjustment object engageable by appropriate operation of the input device;
- image geometry adjustment means stored in the memory, the image geometry means for generating an image geometry adjustment screen on the video display monitor, hiding the input device pointer and generating a simulated input device pointer that indicates changing geometry of the image geometry adjustment screen, receiving positional information from the input device, using the positional information to adjust the image geometry, whereby the simulated input device pointer is moved accordingly, and restoring the input device pointer on the image geometry adjustment screen.
