After-Sight : Raspberry Pi Wearable Vision Assistance
The After-Sight Project aims to assist the blind by providing a low cost visual assistive device. This provides a multiple ways to see with ones ears. The project is based on a Raspberry Pi 3 and uses three types of audio assistance:
Sensory Substitution – The vOICe (“Oh I See”) software has been around for 30 years and runs on many platforms including Android and Raspberry Pi. This software generates an audio spectrograph based on video input. This allows users to train their brains to see with sound.
Object Recognition – Teradeep is a neural network for large scale object recognition. It currently recognizes 1000 objects and has a growing database.
Distance Sensing – Ultrasonic rangefinder reports distance to the nearest object.
Face Detection and localization – Detects and reports where another person has been located.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
