The demonstrated applications include:
(1) an application to show the degree of brain's relaxation on the screen of a mobile phone by using a visualizer
(2) an application to show the degree of brain's tension in chronological order after a user solves about 10 arithmetical problems (addition, multiplication, etc) shown on the screen of a mobile phone
(3) a game application to move a video game character to an intended place as quickly as possible on the screen of a mobile phone. The more the degree of brain's concentration, the more quickly the character moves.
As for (1), when a user calms his or her mind on purpose, the curving lines drawn by the visualizer change to various colors. With regard to (2), if an appropriate application is developed, it will be possible to realize a brain training game in which the challenge level changes in real time in accordance with the degree of brain's tension.
