Article: Using games for training brainwaves Several techniques, researches Focused on games Presentation General Brainwaves Advantages Games Techniques used
Difficulties Often hard to control when untrained Training is difficult Awkward for the participant Training is (often) boring…
Why are games used? More fun! Good feedback Good for balancing tasks More intuitive Better training, easier to train longer
Several Games discussed: Balancing with SSVEP 3D shooter(High/Low Mu) Goal moving(Mental relaxation) Course following(Spec Signals) Balancing (Left/Right Hemisphere)
“MindBalance – the game” Balancing with SSVEP Focusing on flickering squares Showed in previous presentations…
3D Shooter Graphical, “immersive” environment Controlled by high/low mu signals ▪ For left/right control ▪ Forward/backward still with keyboard After some training: ▪ Automatically turning with thinking
Moving to Right/Left Simple, but clear goal Mental relaxation moving towards right ▪ Easier when winning? Makes it difficult! Multiplayer Focus on finding when “relaxed” ▪ Alpha + theta & Alpha + Beta + Theta good indicators of relaxation
“Brainathlon” Simple, but direct goal 3 courses ▪ Specific signal needed for every course ▪ Changing difficulty(starting activation) Multiplayer
Balancing on a rope Main subject of article Complete 3d environment Activation of cortex ▪ Left Cortex = Left, Right Cortex = Right ▪ Equal = straight on rope ▪ Intuitive, but hard to master
Balancing on a rope Feedback in Lower Right corner Based on FFT Power value difference ▪ Processed 2-8Hz(Theta), 12-20Hz(low Beta) Handy for training ▪ Participant learn to control ranges, stabilizes
Interesting graphs: Why second this much higher…? ▪ Mentality before starting?
Training is very beneficial for good results (Often)Takes consistent training for reliable results Still basic control Optimistic future, but still a lot to do Research of 2007, is that old…?
Commercially available: OCZ Neural Impulse Actuator(incl “Far Cry 2”) 3d shooter gaming(€119,-) EMG, EEG, and EOG! Works, but… ▪ Needs training ▪ Resynchronisation Nevertheless overall good reviews!
