Just imagine…iPoint Presenter
The iPoint presenter is a combination of Wii technology and iPhone technology. The idea is that a person can stand in front of a large projection screen, and without touching the screen, manipulate the objects on the screen with only gestures. Cameras are used to track the movements and as with voice technology, certain commands prompt certain actions on the computer screen. Business folks see it as a wonderful presentation device—you can control the computer from a distance and to allow anyone to operate it intuitively and without the need for spoke words. Can you imagine what this technology will do for those with disabilities?
