  1. 1. Avläsning av EEG-data från Emotiv Epoc X för ett SSVEP-baserat braincomputer interface för att spela Snake

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Carl Erenstedt; Alexander Ohlin; David Persson; Gustav Pihlquist; Samuel Widén; Carlos Yechouh; [2021-09-14]
    Nyckelord :BCI; EEG; Snake; SSVEP; CCA; Emotiv Epoc; CNN; responstid;

    Sammanfattning : Denna rapport beskriver arbetet med att utforma ett BCI som kan styra datorspelet Snake i realtid. Spelet styrs genom att inducera steady state visually evoked potentials i hjärnan via flimrande stimuli av vissa frekvenser. Den resulterande elektriska aktiviteten i hjärnan läses sedan ut med hjälp av elektroencefalografi via Emotiv Epoc X. LÄS MER

  3. 2. Statistics and Machine Learning for Classification of Emotional and Semantic Content of EEG

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Oskar Keding; David Ohlin; [2021]
    Nyckelord :Machine Learning; machine; learning; neural; network; statistics; EEG; emotion; semantic; emotional; signal; processing; reassignment; time-frequency; spectrogram; brain processing; bci; CNN; convolutional; Mathematics and Statistics;

    Sammanfattning : Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. LÄS MER
