Anatomy

The Tactera in white, viewed from directly above. The eight Perkins writing keys sit in two angled banks of four, separated by a gap in the middle. The row of 32 cursor routers runs directly beneath them, then the 32-cell braille display spans the full width as a dark strip of raised dots. Three command keys line the front edge, the centre one a wide split bar, and a power switch sits on the right-hand side.

Refreshable braille made digital content reachable. It did not make it easy. Today's users need intelligent tools that simplify information, not just relay it.
