• The MTCW can be set to either Touch or Proximity mode, but they
cannot be used simultaneously.
Proximity
The device has two modes of operation: touchpad, and proximity. The
device is set to proximity mode by command over the USB. In Proximity
Mode the device sends make and break codes over the USB corresponding to
the current status of the proximity sensor. Proximity is detected using the
mutual projected capacitance method.
Joystick Direction Indicators
The MTCW comes pre-printed with four direction indicators: Up, Down,
Left, and Right arranged in the cardinal directions. Instinct Gesture
Recognition Software can easily be set to recognize touches in these areas.

Grayhill’s Instinct Gesture Recognition
Library
What is Instinct?
Welcome to the Grayhill Instinct Software Developer’s Guide. Instinct is
Grayhill’s Gesture Recognition Software Library for Grayhill Touch Devices
that makes developing applications using touch gestures a snap. Instinct
uses proven and tested recognition algorithms to accurately track and detect
single and multi-touch gestures. The Grayhill Instinct Gesture Recognition
Software Library is a C source code library – which is intended to be
included and built into your application. Simple initialization calls allow the
flexible setup of parameters to fine-tune the recognition process for your
application. During normal operation, data from the Grayhill touch device is
passed directly to the library. The data is quickly processed and the results
are passed back to your application.
