This research utilizes Technology Acceptance Mode, Task-Technology fit Model, Decomposed Theory of Planned Behavior to find out the factors that influence users accept or use BCI. And let them operate Brain-Computer Interface to experience how it works by themselves. After fully understood, we have a survey for them. We would like to figure out users' habit and behavior mode.
