## What it is
OptiKey is a free, open-source on-screen keyboard application for Windows that enables full computer control and speech output using eye-tracking devices, a mouse, a webcam, or switches. It is designed primarily as an assistive technology for people with motor conditions such as MND/ALS, serving as an affordable alternative to expensive AAC products.

## Use cases
- type and speak using only eye movements
- control the mouse cursor with gaze
- give a speech-impaired user a communication board
- replace an expensive AAC device with free software
- use a webcam or mouse as an alternative input for typing
- support a pre-literate user with symbol boards

## When to choose
- you need free AAC software on Windows with eye-tracker support
- the user has limited or no hand mobility but reliable eye control
- you want customizable keyboards, symbol boards, and multi-language support

## When to avoid
- you need macOS or Linux support
- you rely on myGaze or older Tobii eye trackers dropped in v4
- you need a lightweight embedded or mobile AAC solution
