Introduction: Blind Guider

Picture of Blind Guider

Blind Guider is a wearable device aims to help blind people to understand their surroundings.

  • It detects the presence of obstacles in front of the user without the need of physical contact.
  • It gives a flashing light to inform surrounding people if the user is walking towards them.
  • It uses a built in compass to guide users to the directions they need.

Blind Guider uses vibration as an indicator of objects in the way, or in the compass mode, of directions. We hope that Blind Guider could provide protection to the visually impaired, and make their life easier.

I designed the head gear type of resent for blind and it indicates obstacles by bleep from miniature buzzer, it also light up a green led.

the flashing strobe is not really necessary unless you are walking at night visually impaired people don't always want that much attention drawn to them I've been legally blind my entire life plus, there have to be smaller boards available would a trinket pro work to reduce space?

This is such a cool idea! Has anyone that is visually impared been able to give you any feed back on it yet?
