Abstract (in Japanese) (See Japanese page) 
(in English) Persons with severe motor disabilities usually use a single switch for operating personal computer.
Patients with progressive motor disabilities have difficulty in the purchase of a switch and the training for its skillful use, due to frequent update of the switch according to the progression of disabilities.
Then we have been developing a versatile single switch, VSN/1, with a photo-reflective sensor array, which is applicable to the detection of both blinking and finger motion.
Its data processing schemes for the two motions, however, were slightly different with each other, limiting its versatility in application.
To eliminate this limitation, this study proposed a versatile detecting method applicable to both blinking and finger motion.
This method was verified to be effective for detecting blinking accurately through experiments using five healthy volunteers.
