The Self-Calibrating Auditory Tone Infrared (SCATIR) Switch is a momentary-contact optical switch with auditory feedback. The SCATIR switch works by detecting a beam of reflected pulsed infrared light. It is suitable for use with a variety of control gestures, such as eye-blink, eyebrow movement, finger movement, head movement, and facial muscle movement. It can be activated at a distance so the controlling body part does not need to be in physical contact with the switch sensor.
SCATIR Switch is available with a gooseneck mount, an eyeglass mount or you can get both mounts in the deluxe kit.
