Graphical pointing device and method for controlling a graphical pointer within a data processing system
First Claim
1. A graphical pointing device for controlling a graphical pointer displayed within a display device of a data processing system, said graphical pointing device comprising:
- a transducer within said graphical pointing device which converts manipulation of said graphical pointing device into electrical signals usable by a data processing system to move a graphical pointer displayed within a display device; and
a graphical pointer speed control within said graphical pointing device for varying a relationship between a pulse rate of said electrical signals and a quantum of manipulation of said graphical pointing device, said graphical pointer speed control having a plurality of settings that permit said graphical pointer to be moved within said display device at various speeds in response to a same quantum of manipulation of said graphical pointing device by selecting differing ones of said plurality of settings, wherein a particular setting among said plurality of settings prevents transmission of pulses from said graphical pointing device to said data processing system such that said graphical pointer is held stationary within said display device regardless of manipulation of said graphical pointing device while said graphical pointer speed control is set to said particular setting.

Abstract
A graphical pointing device and method for controlling a graphical pointer displayed within a display device of a data processing system are disclosed. The graphical pointing device includes a transducer, which converts manipulation of the graphical pointing device into electrical signals utilized by a data processing system to move a graphical pointer displayed within a display device. In addition, the graphical pointing device includes a graphical pointer speed control for varying a relationship between the electrical signals and manipulation of the graphical pointing device, thereby enabling the graphical pointer to be moved within the display device at various speeds by differing adjustments of the graphical pointer speed control without modifying programming within the data processing system.

8. A method for controlling a graphical pointer displayed within a display device of a data processing system, said data processing system having a graphical pointing device including a transducer which converts manipulation of said graphical pointing device into electrical signals utilized by said data processing system to move said graphical pointer, wherein said graphical pointing device further includes a graphical pointer speed control having a plurality of settings, said method comprising:
-
in response to manipulation of the graphical pointing device, generating one or more electrical signals having a pulse rate; if said graphical pointer speed control is set to a particular setting among said plurality of settings, preventing transmission of pulses from said graphical pointing device to said data processing system such that said graphical pointer is held stationary within said display device regardless of manipulation of said graphical pointing device; and if said graphical pointer speed control is set to one of said plurality of settings other than said particular setting, adjusting a relationship between a pulse rate of said electrical signals and a quantum of manipulation of said graphical pointing device in accordance with the setting.
