| Abstract [eng] |
Due to quick technology evolution, brain measurement devices are also affected - their size is getting more compact and accuracy is gradually increasing. For this reason, some of electroencephalographs are being applied not only for medical purposes, but also for common, everyday use. By having an access to affordable and comfortable brain measurement devices, it’s possible to widen the field of use of this type of hardware. To ensure effective use of the device and to present measured and evaluated brain activity the best way possible, a product is required, managing to evaluate retrieved EEG device information by taking into an account the status of connection quality, discarding false or poor quality signals and providing user with recommendations, depending on the purpose of the product. Brain activity measurement devices can be used in meditation - software could inform user, when he should concentrate, when to relax. The goal of this project - to create interface with video game by using EEG device and it’s capabilities, which allows to monitor user’s mental state during yoga exercises, correcting his mistakes (for example: nervous state during yoga idle phase) and providing results about mental activity. Document provides product analysis, architectural specification. By having a finished product, a software quality analysis is conducted, alongside with experiments, evaluating accuracy of algorithms, which evaluate user’s relaxed state. Their results are presented in the conclusions, with suggested recommendations for improvements - to use alpha wave power absolute and session values as indicators of calm user’s state. |
