The application of the light-guided environmental control device will greatly increase the quality of life of certain persons with disabilities. This hands-free mechanism will allow the user to perform many daily tasks without the need of an aid. It is an environmental control and a wheelchair control that is driven by a light emitting head switch. One of the main foci of the project is to remove many of the cumbersome control switches being implemented today, and replacing them with one compact model. This product is to perform all operations currently performed by head arrays and switches, as well as standard joysticks. It is being designed to be used primarily by those people without the use of their limbs, especially those looking to gain a great deal of independence.

The light activated position sensing array will bring great independence to many persons with disabilities. Enabling those that have limited to no use of their limbs, this product will allow its user to perform many day to day activities that may have not otherwise been possible without outside assistance. The system is a hands-free electric wheelchair control that will also function as a powerful environmental control tool. Guided by a light emitter worn on the user's head, it will replace orally activated (sip and puff) switches, as well as any other switches that may be mounted on or near the user's head.
