A modern and friendly way of interacting with machines is by touching its display. In order for the machine to detect touches a field is project on top of the screen. This is done by a transparent layer in front of the display: a projected capacitive touch screen (PCAP). The electronics connected scans the field for disturbances in capacitance. Algorithms distinguish touches and report these to the machine over USB, RS232 or I2C.

  • An electronic and mechanical touch screen design
  • Production files for parts and production tools
  • Measurement electronics
  • Tuning

Engeen has years of experience in designing custom touch screens and can assist in acquiring such.
