PACS: Communication and environment control system for disabled

There are a lot of disabled people in the world. In many cases persons with severe disabilities who can't move or speak are isolated. These persons at least have one primitive way to communicate with others (it could be head movements, eye blink, voice intonations, mimics and others). The usage of electronics can help to transform it into understandable communication signs for others or into control signals for devices. Electronics means improve self-sufficiency of disabled people and enable communication with others. We have created communication and environment control system for physically disabled persons with speech and language impairments. A very important feature of this system is that it is controlled by one on/off type switch. Alternative input devices as head pointer, eye blink registrar, person's capacity registrar, suck-blow tube, etc, can be used instead of the similar switch.
