MULTI-TOUCH SURFACE PROVIDING DETECTION AND TRACKING OF MULTIPLE TOUCH POINTS
First Claim
Patent Images
1. An apparatus detecting at least one touch point comprising:
- a surface having a first dimension and second dimension;
a first plurality of sensors deployed along the first dimension and generating a first plurality of sensed signals caused by the at least one touch point, wherein the first plurality of sensors provide a first dataset indicating the first plurality of sensed signals as a first function of position on the first dimension;
a second plurality of sensors deployed along the second dimension and generating a second plurality of sensed signals caused by the at least one touch point, wherein the second plurality of sensors provide a second dataset indicating the second plurality of sensed signals as a second function of position on the second dimension, wherein the first plurality of sensors and the second plurality of sensors operate independently to each other; and
a trained-model based processing unit processing the first and second datasets to determine a position for each of the at least one touch point.
