The joy of being able to do what I couldn't do.
Traditionally, "operation support switches" for communication and other purposes have included contact-type, electrostatic, photoelectric, breath-operated, piezoelectric, balloon-type, and others. The choice of switch type is based on usability according to the progression of the medical condition and the physical capabilities of the user. However, due to changes in the medical condition, it may be unavoidable to replace the switch.
Progressive muscular atrophy diseases such as ALS (amyotrophic lateral sclerosis), which is a neurodegenerative disease, eventually lead to the inability to move all muscles. However, eye movements (eyeballs and eyelids) often remain functional until the end. By utilizing this eye movement capability, individuals who have been passively waiting can actively call for help and operate devices around them.
We developed the "Eye Switch" with the hope of assisting in the joy of being able to do what was previously impossible.
