Then, the line-of-sight for the detection of the eye movement direction is developed for the communication to determine whether the user is looking left or right, which is based on the computation of the center of gravity with pixel number in the eye image. Further, a newly proposed blink detection method using afterimage is applied to the developed system. This study will be extended to the application that everyone can use easily and quickly to express his\/her thoughts and requests.<\/p>","DOI":"10.4018\/ijsi.2017070105","type":"journal-article","created":{"date-parts":[[2017,5,31]],"date-time":"2017-05-31T13:55:28Z","timestamp":1496238928000},"page":"64-76","source":"Crossref","is-referenced-by-count":0,"title":["Line-of-Sight Detection Using Center of Gravity with Pixel Number Variation"],"prefix":"10.4018","volume":"5","author":[{"given":"Takahito","family":"Niwa","sequence":"first","affiliation":[{"name":"Aichi Institute of Technology, Toyota, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ippei","family":"Torii","sequence":"additional","affiliation":[{"name":"Aichi Institute of Technology, Toyota, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naohiro","family":"Ishii","sequence":"additional","affiliation":[{"name":"Aichi Institute of Technology, Toyota, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJSI.2017070105-0","unstructured":"According to the Cabinet Office Disabilities Report.
