Abstract
A noise-free portable EEG system is provided. The system has hardware and software and can evaluate mental state quantitatively. The quantitative data of mental states and their levels can be applied to various areas of brain-machine interface including consumer products, video game, toys, military and aerospace as well as biofeedback or neurofeedback.
Claims31
An apparatus for determining the mental state of a user, the apparatus comprising:
- a frame;
- one or more dry-active sensors located on the frame that are capable of detecting the brain waves of a user when the sensors touch a skin portion of a user and of generating brain wave signals;
- and
- a processing unit that receives the brain wave signals, processes the brain wave signals and generates a signal corresponding to a level of a mental state of the user.
1 more element
A method for determining the mental state of a user, the method comprising:
- detecting, using one or more dry-active sensors located on the frame, a set of brain wave signals of a user when the sensors touch a skin portion of a user;
- and
- receiving, at a processing unit, the set of brain wave signals;
- and
- processing, in the processing unit, the brain wave signals to generates a signal corresponding to a level of a mental state of the user.
