I have downloaded the camera mouse tool to teach myself how to use the system and discover the sensitivity of the curser movement when linked to a facial point. I was amazed at the degree of movement and the level of control one had in using the system. I linked it to the computers own on screen keyboard using the automatic click system and was able to type data onto the screen. My reason for testing the system is to teach my niece who has some mental challenges, no verbal communication and limited physical control of her limbs another way of communicating with us. My experience is limited but I can already see the possibilities of this system for people trapped either physically or mentally in their own world. I shall continue to learn and hopefully pass on that learning to my niece. I have a problem opening up programmes such as word as this requires a double click to start.
