An eye-typer is an assistive technology device or software that allows individuals to type or interact with a computer using only their eye movements. This technology is particularly beneficial for people with physical disabilities that limit their ability to use traditional input methods like keyboards or mice.
How Eye-Typing Works:
- Eye-Tracking Technology: The system uses an eye-tracking camera or sensor to monitor where the user is looking on the screen.
- Virtual Keyboard: A virtual keyboard is displayed on the screen. The user gazes at specific keys to select them.
- Selection Mechanism: The system detects when a user is focusing on a particular key, often through a prolonged gaze or a blink to confirm the selection.
Use Cases:
- Individuals with motor neuron diseases (like ALS) or spinal cord injuries.
- People with locked-in syndrome or severe cerebral palsy.
Advanced Features:
- Some eye-typers include predictive text to speed up the typing process.
- Others integrate with communication apps, enabling users to speak through synthesized voice outputs after typing.
Eye-typing technology represents a significant step forward in making digital communication more inclusive.
