Becdot Teaches With Touch

Braille is a tactile system of communication, used the world over by those with vision impairment. Like any form of language or writing, it can be difficult to teach and learn. To help solve this, [memoriesforbecca] has developed Becdot as a teaching tool to help children learn Braille.

The device is built around four Braille cells, which were custom-designed for the project. The key was to create a device which could recreate tactile Braille characters at low cost, to enable the device to be cheap enough to be used a children’s toy. The Braille cells are combined with an NFC …read more http://pje.fyi/Ps6G8H

Visual Scanner Turns Obstacles into Braille

This interesting project out of MIT aims to use technology to help visually impaired people navigate through the use of a haptic feedback belt, chest-mounted sensors, and a braille display.

The belt consists of a vibration motors controlled by what appears to be a Raspberry Pi (for the prototype anyway) with a distance sensor and camera connected as well. The core algorithm is designed to take input from the camera and distance sensors to compute the distance to obstacles, and to buzz the right motor to alert the user — fairly expected stuff. However, the project has a higher goal: …read more http://pje.fyi/PLPWyl
