Abstract

A touchscreen system includes a touchscreen configured to receive touch data from a user, a plurality of modules, and a touch performance profiler module communicatively coupled to at least one of the plurality of modules. The plurality of modules are collectively configured to process the touch data and display an output based on the processed touch data. The touch performance profiler module is configured to monitor the at least one of the plurality of modules in real-time and output performance attributes of the at least one of the plurality of modules based at least in part on the monitoring.
