Yes/No CVI Device

Yes/No CVI Device - open-source assistive technology prototype by the University of Pennsylvania community

About this project

Cortical Visual Impairment (CVI) often accompanies Cerebral Palsy - a visual impairment caused by the brain, not unhealthy eyes. This device was requested by a therapist at HMS for her therapy sessions and has already requested another. The device consists of 2 lines of LED lights (red and green) that bounce along a path at controlled speed. We are refining the solution through their feedback.

The challenge

This project will help those who struggle with communication to effectively communicate a yes or no, promoting accessibility and independence.

Who it helps

Children learning communication, nonverbal users, people in rehabilitation programs

How it works

This project will help those who struggle with communication to effectively communicate a yes or no, promoting accessibility and independence, as well as training thier eye muscles to move along these paths.

Following the LED clusters will allow users to mimic a shaking and nodding head to effectively communicate yes or no.

An LED device with clusters of LEDs in one line going vertically and another going horizontally, pointing out a shaking direction (left and right) and nodding direction (up and down).

Tools/Parts Needed:

PC or MAC 17+ - hardware

Prusa Slicer (or printer slicer of choice) - software

FDM Printer - hardware

5 mm LEDs

Wires

Arduino Uno

Slide Potentiometer

Rocker Switches

Soldering set
