The BrainPort as a balance aid is very useful to some people.

The Back-Vision TVSS failed because software was not advanced enough to process the cameras's view to a simplification of the scene. Now AI is developing enough to allow SW to create a model of the 3D world within view of a person wearing the vision device. When this is done the simplified view presented could be supplemented with computer interaction to allow identification of objects seen. This would be very useful for finding a tool I just set down or a screw I dropped somewhere; or to magnify fine needlepoint or other work like soldering chips to a PCB. The interaction could be done by audio menu, voice commands, buttons, and highlighting on the tactile display.
The Opticon was very usefull, but it was replaced by scanners, OCR, and voice output.
The current GPS systems suitable for blind users are not very good. One uses a GPS with tactile-input display, so a tickler unit is bolted to the GPS unit. It has its own processor to impliment your commands. The units are hard to use and you still need to use a cain or a dog.
