| Outline of Final Research Achievements |
In individuals with motor disabilities such as ALS, progressive speech impairment necessitates the use of an assistive communication aid. Because they have limited control over body movement, we have been investigating the utility of the EOG as a means of accessibility and previously reported a technique to identify voluntary eye blink on the EOG. Because of the simplicity of using voluntary blinks as an input method, in this study we investigated the use of consecutive blinks and gaze as a means of accessibility.First, by examining the influence of consecutive voluntary eye blinks and different blink intervals on EOG waveforms and then comparing specific EOG features of the blink intervals, we revealed that blinks at intervals of <300ms generate a unique waveform. It is also possible to determine the point of gaze by EOG, albeit not highly accurately, and therefore we also investigated if several blink-based input methods could be developed by identifying approximate gaze positions.
