Reading with a pillow switch

Please check out this link to find out how to read on an iPad using only a pillow switch. This is based on several months of effort for my friend Dave, who sustained a severe cervical injury last year and is unable to move his arms or legs. He is now reading very well using these methods, and we have been working together to refine them.
