TouchPoint HMI
The tech behind the touch
TouchPoint chips power SmartSurface touch interfaces with accuracy and control
UltraSense TouchPoint HMI Controllers fully integrate multi-mode touch sensing, lighting control, and algorithm processing in a single chip – powering a new generation of Human-Machine Interfaces
Fully Integrated Sensor Systems on a Chip
TouchPoint products use a combination of capacitive, ultrasound, and force-sensing technology for a variety of applications
