Method For Determining Coordinates Of Touches

An apparatus comprising:

• a first set of lines, each line of the first set of lines comprising electrodes;
• a second set of lines, each line of the second set of lines comprising electrodes, the second set of lines capacitively coupled to the first set of lines;
• and
• one or more computer-readable non-transitory storage media comprising logic that, when executed is operable to:
• receive a first set of signal values from the first set of lines;
• store the first set of signal values in a first two-dimensional array;
• determine a first one-dimensional representation associated with a first axis of the first two-dimensional array;
• determine a first area associated with at least one touch detected by the touch sensor from the first one-dimensional representation;
• determine a second one-dimensional representation associated with a second axis based on the first area, the second axis being different than the first axis;
• determine a second area associated with at least one touch detected by the first set of lines from the second one-dimensional representation;
• and
• determine coordinates for the at least one touch detected by the first set of lines based on the first area and the second area.

One or more computer-readable non-transitory storage media comprising logic that, when executed is operable to:

• receive a first set of signal values from a touch sensor, the touch sensor comprising a plurality of electrodes;
• store the first set of signal values in a first two-dimensional array;
• determine a first one-dimensional representation associated with a first axis of the first two-dimensional array;
• determine a first area associated with at least one touch detected by the touch sensor from the first one-dimensional representation;
• determine a second one-dimensional representation associated with a second axis based on the first area, the second axis being different than the first axis;
• determine a second area associated with at least one touch detected by the touch sensor from the second one-dimensional representation;
• and
• determine coordinates for the at least one touch detected by the touch sensor based on the first area and the second area.
