| 20090309847 | APPARATUS AND METHOD FOR PROVIDING MULTI-TOUCH INTERFACE CAPABILITY - An apparatus and method for providing multi-touch human to computing device interface capability on devices having single-touch interface devices. The apparatus and method use heuristics based analysis of successive touch point X,Y coordinate pairs provided by the single-touch interface device to identify a multi-touch occurrence. A further heuristics based function is employed to derive X,Y coordinates for a second touch point from two successive pairs of X,Y coordinates provided by single-touch interface device. | 12-17-2009 |
