What is it?
An eyeblink switch is a specialized assistive technology device that detects intentional blinking or small eye movements to activate a connected system, such as a communication device, computer, or environmental control. It is designed for individuals with very limited physical movement, particularly those with severe motor disabilities. In the inclusive classroom, eyeblink switches offer a powerful access method for students who cannot reliably use their hands, head, or other body parts to interact with their environment.
How to use it?
To use an eyeblink switch, the device is positioned near the student's eye and calibrated to detect voluntary blinks or slight eye movements. The switch can then be connected to a communication system, adapted learning tool, or computer interface. Educators and support staff work with the student to teach intentional blinking as a form of control, often starting with simple cause-and-effect activities and gradually building toward more complex communication or academic tasks as the student's skills develop.
Why use it?
Eyeblink switches are vital in inclusive classrooms because they provide a means of participation and communication for students with profound physical disabilities. By offering access through even the smallest, most consistent movement, these switches allow students to make choices, express needs, and engage in learning activities alongside their peers. Incorporating eyeblink switches into classroom practice promotes independence, dignity, and inclusion, ensuring that every student has a voice and a way to connect with the world around them.
