Abstract:
1. A method comprising: receiving data indicative of movement of a conductive object on a first area of a touch-sensor device, wherein the first area comprises a multi-dimensional sensor array having a plurality of columns and rows of first sensor elements; receiving data indicative of a presence of the conductive object on a second area of the touch-sensor device, the second area being different than the first area, wherein the second area comprises a one-dimensional sensor array having a plurality of second sensor elements and a plurality of indication sensor elements corresponding to a plurality of positions on the second area of the touch-sensor device, wherein each of the plurality of second sensor elements shares a column trace with a corresponding column of first sensor elements, and wherein the plurality of indication sensor elements are coupled to a row trace that is not shared with the plurality of first sensor elements, wherein the plurality of rows of first sensor elements have a first row height and the plurality of second sensor elements have a second row height, the second row height being different than the first row height; responsive to receiving the data indicative of the presence from the indication sensor element, detecting the presence in one of the plurality of positions detected without performing an X-Y dimension comparison within the second area of the touch-sensor device; and processing, by a processing device, a function mapped to the one of the plurality of positions based on detecting the presence in the one of the plurality of positions wherein a different function is mapped to each of the plurality of one positions, and wherein the multi-dimensional sensor array is coupled to the processing device through a plurality of pins and wherein the one-dimensional sensor array is coupled to the processing device through an additional pin separate from the plurality of pins, wherein each of the first sensor elements has a first shape, each of the second sensor elements has a second shape, and each of the indication sensor elements has a third shape, the first shape, the second shape, and the third shape being different from one another.
