Communication poses many challenges for people with hearing, vision, or speech loss.

People who have lost one of their limbs, or have lost the ability to walk completely due to paralysis or spinal cord damage, use prostheses or exoskeletons that partially compensate for the loss.

People who have lost all or part of their sight are significantly limited in their lives, unable to perform the simplest of tasks, unable to see their companion or having difficulty navigating and reading.

Eye tracking devices are communication and control systems that monitor eye movements and allow people with total loss of mobility and speech to control a computer or mobile device by eye movement alone.

These devices also aid in communication, allowing the deaf or hard of hearing to return to our world of sound, music and speech.
