Here’s a concept that would really help the visually impaired and blind. The Touch & Go navigation system is a combination of a hand gadget and an earpiece that will give you directions as a relief map on its wearable navigator with tactile display.
The scale is 1:1,000 and the center of the display is where the user is currently. An arrow points toward where you should go, while audio through the earphones will speak any other details needed. Pretty interesting take on navigation for the blind.
We hope to see this one become real.
