Abstract: The present invention involves a computer based method and system employing an index finger controlled pointing device for manipulation and control of the keyboard. The user employ their index fingers as the pointing device from the home row typing position. All pointing device operations and thumb button operations can proceed without moving either hand from the home row key position. This represents a significant improvement over the current state of the art by keeping the user's hands and fingers in place over the home row of keys on the keyboard. This improved approach is the basis of a major embodiment of this invention.

Abstract: When using a periodically interrupting timing device to implement software timers, a wide variety of resolutions for such timers can be provided with minimal interrupt overhead. This is achieved by dynamically reprogramming the frequency of the interrupting device to be at a selected low rate necessary to provide the resolution requested by the next, impending timer to expire. This is particularly useful when a periodic timing device is the only device available to implement variable timer resolutions.
