TapSight and N5Digital design projects
From the essay
Design a miniature handheld wireless two-way communication and control device enabling visually impaired users to access, control and process text-based information stored on PCs, tablets, cell phones, and other electronic devices, as well as on Internet sites. TapSight can be used by anyone wishing to learn Braille and read Braille-based electronic books or communicate through tactile perception. The objective is an electronic device based on tactile perceptions for communication and data exchange while reducing reliance on audio interface.
