Michael suffers from Thoracic Outlet Syndrome (TOS) which prevents him from using a computer because the keyboard and mouse fatigue his arms and hands. Similar to other repetitive strain injuries (RSI) like Carpal Tunnel Syndrome, TOS causes heaviness and pain in the arms and hands.

For more information about TOS and treatments for TOS there is great information at the PubMed Health website.

Michael controls the entire computer using his eye movements and his voice for a completely hands free PC experience. With this set-up Michael rarely will need to use a keyboard or mouse again. This has helped him stay productive for a local fire department in the Los Angeles area where he does a lot of data entry. He uses the EyeOn eye tracking mouse from EyeTech to control the mouse. He also uses the voice recognition software built into Windows 7 to type with his voice. This combination provides a natural way for him to control the computer completely hands free!
