| Outline of Final Research Achievements |
This research solved the problem of Brain-Computer Interface (BCI) which is one of switches in the living environment of ALS people. Needs survey was conducted for ALS persons and occupational therapists, (1) improvement of character input efficiency, and (2) electrode arrangement according to usage attitude.
(1) We devised a method to shorten character input time while maintaining high character input accuracy. As a result of experiment and simulation, the input time was shortened from 81.6 (sec / char) to 21.1 (sec / char) at best for 1 character, improved by 60.5 seconds.
(2) Electrode placement with less load in life posture where electrode could not be placed in the back of the head was studied. As a result of statistically determining the optimal electrode placement method for ALS patients and conducting experiments, it was possible to maintain 100% correct answer rate from 8 to 1 electrode.
