I.C.T Unit 3c Essay
In this part of the coursework I am going to layout all the needs of a person who has mobility impairment. His name is Scott and he is a 19-year-old engineering student with muscular dystrophy. Scott needs special technologies in order to keep his life running as normal as possible. Some technologies that Scott may need are:  Tracker Ball Head Tracker  Screen Keyboard Brain Switch  Voice Recognition Tracker Ball: A tracker ball is an input device where a finger is used to rotate a ball.
This moves a pointer to the screen.
A tracker ball is very useful to Scott. This helps him to move the pointer around easily. The tracker ball is a replacement for a normal mouse. Scott has troubles gripping the mouse because of his deficiency. It is easier for him to use a tracker ball because this allows him to gently move the ball just with one finger. This is easier because his hands can shake quite a lot and he cannot control this so using just one finger can make life so much easier and its not as frustrating because he dont need to use up all his energy.
