Assistive System for Visually Impaired Children

It is said that visually impaired children learn about the world in a different way than other sighted children. They cannot watch people and objects and could not imitate what they see, and may be at first not move about freely. This idea aims to help them by trying to stimulate their learning and exploration through hearing and feeling objects around them.

In the first illustration, a visually impaired toddler may be encouraged to explore her surroundings more by following a guide that will make sounds or talk to her. The basic components for this set up are:
  • sound brick - for communicating with the child
  • intelligent brick - for processing information
  • ultrasonic sensor - for detecting obstacles that may be in the way of the child

optional components may be:
  • color sensor
  • touch sensor

The second illustration gives the option of setting up multiple guides for the child, but this time with less components each. This idea is similar to the beeping sounds that may be heard from pedestrian crossings in Japan, wherein visually impaired individuals are able to cross the street using a cane following Tenji blocks on the pedestrian pavement, and by following the sounds emitted at the crossing. Since the components will only need to emit sound, the basic components may be:
  • sound brick - to emit sounds (pre-recorded speech, etc.)
  • motion sensor - to detect if the child is within the vicinity

optional components may be:
  • intelligent brick - for communicating with a central controller, allows for more flexibility and features

The third illustration is about helping the child distinguish objects, colors, etc. This may be helpful for people with color blindness, but may be extended to include more features to help individuals to help classify bricks (e.g. using the existing classification of Lego bricks for blind people, etc.)

Basic components may include:
  • sound brick
  • color sensor
  • intelligent brick

optional components for extended features may be:
  • Machine learning techniques
  • Mobile phone with camera
