The wireless VisionBoard offers a significant advantage to people who find it painful or difficult to use a traditional keyboard by improving readability and reducing eyestrain with big 1-in/2.54-cm square keys. The large, bold white-on-black letters and numbers are easy to see with a contrast ratio of 21:1 and are almost 250% larger than the print on standard keyboards. Users with low vision or physical limitations can increase and improve capabilities with greater comfort and control.
The wireless VisionBoard includes a USB A wireless receiver.
