Touchscreen Simulator

Application ID: 30841

Intended as a tool for early proof of concept in capacitive touchscreen device development, the Touchscreen Simulator app evaluates a simulated capacitance matrix as well as the electric field norm.

The app computes the capacitance matrix of a touchscreen in the presence of a human finger phantom, where the position and orientation of the finger are controlled via input parameters. This includes electrode unit cell array size, the finger location, angle and touch level, the substrate and superstrate thicknesses and their material properties.

This application example illustrates applications of this type that would nominally be built using the following products:
