Heat-sensing touch interface

A method, comprising:

• receiving touch data from a touch sensor array of the touch device, wherein the touch data indicates a plurality of touchpoints on the touch device;
• receiving thermal data from a thermal sensor array of the touch device, wherein the thermal data is associated with the touchpoints, the thermal sensor array including a plurality of heat sensors that detect a plurality of heat signals across the thermal sensor array as the thermal data;
• performing temperature-based clustering of the touchpoints to generate clustered touch data;
• classifying the clustered touch data as user input or non-user input based on a touch profile indicated by the clustered touch data and a thermal profile indicated by the thermal data;
• and
• interpreting and responding to the user input.

A computer-readable storage medium having program instructions recorded thereon that, when executed by a processing circuit, perform a method comprising:

• receiving touch data from a touch sensor array of the touch device, wherein the touch data indicates a plurality of touchpoints on the touch device;
• receiving thermal data from a thermal sensor array of the touch device, wherein the thermal data is associated with the touchpoints, the thermal sensor array including a plurality of heat sensors that detect a plurality of heat signals across the thermal sensor array as the thermal data;
• performing temperature-based clustering of the touchpoints to generate clustered touch data;
• classifying the clustered touch data as user input or non-user input based on a touch profile indicated by the clustered touch data and a thermal profile indicated by the thermal data;
• and
• interpreting and responding to the user input.
