Red-M has minimum delay (not more than 20ms) and allows to identify user’s sight direction with an accuracy of 0.5 degree. Effective field of view is 32cm x 21cm, while recommended distance to the face of the user is from 50 to 75 centimeters.

The module works under Windows XP, Vista, 7, 8 (32-bit and 64-bit) operational systems. Free software kit for developers allows them to create additional applications to work in conjunction with Red-M.

Fast calibration, high sight measurement accuracy and ability to adapt to various lighting conditions make Red-M an effective assistive technology for medical institutions and personal use. When used in conjunction with virtual keyboards, it provides paralyzed people with a possibility to type texts, thus communicating with their relatives, friends and medical personnel. Furthermore, this device can also be used in ophthalmological researches. SMI Red-M can be used not only as an assistive technology, because it allows identifying the zones of interest during expert evaluation of websites, software and various services.
