Features
The GUI makes it easy for even a beginner to develop touch user interfaces.
Simple GUI operations allow even a beginner to create the configuration for use with a touch user interface, monitor the state of input through the touch sensors, and adjust parameters.
Furthermore, since this tool can adjust tuning parameters and reflect the results through display in real-time, it is very useful for finding the appropriate parameters in various situations, such as in the presence of much static electricity or in cases of use with wet hands.

Automatic tuning for touch sensor sensitivity
This tool enables automatic tuning for the sensitivity of the capacitive touch sensors. You can complete basic tuning within a few minutes by following the instructions in the pop-up messages.
图像
3D gesture recognition
You can develop a gesture application that reacts "by anyone's hand" without any specialized skills just by actually performing the gesture that you want AI to remember on the capacitance sensor.
