Impairment simulator software

The vision and hearing impairment simulator is an installable application that enables you to:

  • Apply simulated vision impairment to your own images, or any third party program running on your computer.
  • Export the results to an image file, ready to insert into a presentation.
  • Listen to audio clips with simulated hearing impairment.

Simulating impairment helps to learn about the different vision conditions, and communicate the corresponding real-world issues to others.
