Tactile geometry

 

Type of project: Prototype

Disability concerned: Visual disability, Dyspraxia

Topics: Autonomy, Education, Inclusive school

Status: In progress

The aim of the project is to develop a geometry board to make it easier for people with a visual impairment (VI) to find their way around a mathematical plane.

The prototype is a geometry board that makes it easier for people with a visual impairment (VI) or who are blind to learn how to find their way around a mathematical plane. The board would be useful during compulsory schooling, from the age of 8 to 15. It would be used to overcome the difficulties associated with creating axis systems and would replace the drawings usually used by mainstream pupils.

Over the last few years, a model made from a squared wooden board has been tested with several pupils aged 11 to 15.

One of them was blind and others had more or less severe sight impairment. The board has a grid system engraved into the material, with a hole at each intersection to accommodate a locating aid in the form of a pin. This test phase validated the concept. Without this tool, learning certain aspects of mathematics would simply not be possible for people with VI. However, this model is not efficient enough as it stands. A new concept needs to be devised and designed through a collaborative process involving people with VI.

The main points to work on are

  • Tactile and visual interface: according to initial tests, the ideal interface does not necessarily seem to be the same depending on the level of disability. The prototyping process will make it possible to test several variables.
  • Modularity in manufacture (scalable and customisable manufacture) and in use (modular system) depending on the pupil’s level of education and level of disability.
  • Weight and size: the tool must be transportable. Research is needed into the ideal dimensions and the materials used.
  • A more efficient reading and handling system (ergonomics of use) in response to a specific context of use (in the classroom).
