OptiKey is an on-screen keyboard that is designed to help Motor Neuron Disease (MND) patients interact with Windows computers. When used with an eye-tracking device, OptiKey's on-screen keyboard allows MND patients to complete tasks, such as email composition, using only their eyes. OptiKey can also be used with a mouse or webcam. Unlike expensive and unreliable Alternative and Augmentative Communication (AAC) products that are difficult to use, Optikey is free, reliable, and easy to use.

Getting Started

The OptiKey Wiki contains OptiKey's user guides, installation and system requirements, and additional support information. OptiKey's Windows installer can be downloaded from the latest release. To get an understanding of OptiKey's use, users should watch Optikey's introduction video.

Supported Platforms

OptiKey uses the .Net 4.6 Framework and is designed to run on Windows 8 / 8.1 / 10.


If users encounter an issue with OptiKey, such as a software crash or an unexpected behaviour, users should add an issue ticket to OptiKey's issue tracker. Users are encouraged to check if their issue is already being tracked by OptiKey before creating a new issue ticket.

The following information should be specified in an issue ticket:

  • How OptiKey was being used
  • What the user expected to happen
  • What the user actually experienced
  • Steps to reproduce the issue
  • Any other information that helps to describe and/or reproduce the problem (ex. screenshots)
