Abstract
A method for detecting and tracking multiple fingers in a two dimensional set of results using oversampling hill climbing and descent with range.
Claims22
A method for detecting and tracking multiple objects using a two dimensional set of measurements from a touch sensor, said method comprising:
- 1) scanning a two dimensional array of locations to identify a first finger location having a result which is greater than zero such that it indicates the presence of at least one finger;
- 2) performing a hill climbing procedure to determine if there is a location immediately adjacent to the first finger location that has a higher value;
- 3) repeating the hill climbing procedure until the highest first finger location is found;
- and
- 4) performing a hill descending algorithm to identify a boundary between the first finger location and a second finger.

A method for detecting and tracking a single object using a two dimensional set of measurements from a touch sensor, said method comprising:
- 1) scanning a two dimensional array of locations to identify a finger location having a result which is greater than zero such that it indicates the presence of the finger;
- 2) performing a hill climbing procedure to determine if there is a location immediately adjacent to the finger location that has a higher value;
- and
- 3) repeating the hill climbing procedure until the highest finger location is found.
