20.500.12556/DKUM-42127 VMESNIK MOŽGANI-RAČUNALNIK NA OSNOVI POTENCIALOV SSVEP IN NJEGOVA UPORABA V RAČUNALNIŠKIH APLIKACIJAH SSVEP - BASED BRAIN-COMPUTER INTERFACE IN COMPUTER APPLICATIONS V diplomskem delu obravnavamo vmesnik možgani-računalnik na osnovi potencialov SSVEP in raziščemo možnosti za njegovo izvedbo ter uporabo v računalniških aplikacijah. Predstavimo zasnovo izvedenega vmesnika z vidika strojne opreme, kjer smo uporabili ojačevalnik za elektroencefalograme avstrijskega proizvajalca g.tec in osebni računalnik. Prav tako opišemo programski vidik vmesnika, kjer smo za implementacijo eksperimenta uporabili odprtokodno platformo BCI2000 oz. njeno izpeljanko BcPy2000, medtem ko je bila analiza podatkov izvedena s pomočjo programskih razširitev NumPy in SciPy. V delu predstavimo problematiko izvedbe vmesnikov SSVEP s pomočjo osebnega računalnika in načine, kako smo jo skušali zaobiti. Na koncu predstavimo eksperimentalni protokol ter rezultate in meritve eksperimenta. In this thesis we address the topic of brain-computer interface, based on SSVEP signals and examine the possibilities of it's implementation, as well as it's use in computer applications. We present hardware structure of the implemented interface, where we used gUSBamp amplifier and active electrodes produced by the g.tec manufacturer, connected to a personal computer. As for the software part, interface was implemented using the BCI2000 open source platform, with it's BcPy2000 python derivative. Data analysis was done using NumPy and SciPy python's extensions. We also address performance issues, emerging from implementation of the interface on a standard personal computer and present software solutions to overcome them. At the end we present the experimental paradigm and sistematically evaluate the implemented interface.
