This single 2lb device has four tools in one that produce instant book-to-speech. The real-time response is achieved thanks to instant scanning by photographing. A patented motion detector allows scanning 20 pages per minute, without pushing a button! All you do is turn pages. Up to 40X magnification with speech. The Zoom-Twix has an all-purpose auto-focus optical zoom camera for 360 degree viewing at any distance. Easy access and control by mouse and keyboard. Store snapshots on a CD, DVD or key chain memory and view them without Zoom-Twix.
