Brain Wave Control Simple introduction of the brain Data Acquisition Apps Drawbacks & Future Q&ASlide 3: What is BCI?Slide 4: Brain -Computer Interface - Direct Neural Interface or Brain-Machine Interface Direct communication pathway between a brain and an external device. Research on BCIs began in the 1970s at the University of California Los AngelesHow does it work?: How does it work? Signal Acquisition Signal Processing DevicesBrain Wave Control: Brain Wave ControlBrain Wave Control: Brain Wave Control Active α (8 – 12 Hz): relaxed/reflecting β (12 – 30 Hz): alert/working - Training - MisjudgmentBrain Wave Control: Brain Wave Control Passive Evoked potentialsBrain Wave Control: Brain Wave Control Passive Evoked potentialsBrain Wave Control: Brain Wave Control Passive Evoked potentialsData Acquisition: Data AcquisitionData Acquisition: Data Acquisition Invasive BCIs Non-Invasive BCIs Partially-Invasive BCIs Wireless BCIsInvasive BCIs: Invasive BCIs Implanted: grey matter Signals: highest quality Scar-tissue build-up Target: repairing damaged sight providing new functionality to persons with paralysis Artificial Vision SystemElectrode Arrays: Electrode ArraysApp.- Artificial Vision: App.- Artificial Vision 4X4 16 pixels 8X8 64 pixels 12X12 144 pixels 16X16 256 pixels 32X32 1024 pixels 128X128 16384 pixelsNon-Invasive BCIs: Non-Invasive BCIs poor signal resolution power muscle implants and restore partial movement Interfaces EEG MEG MRIMEG: MEG Magnetoencephalography Magnetic Field: 10 -15 T ~10 -13 T (Weak!!)

Sensors Shielded RoomMagnetic Field: Magnetic FieldPartially-Invasive BCIs: Partially-Invasive BCIs Implanted: skull lower risk of forming scar-tissue in the brain Signal quality between invasive BCIs & non-invasive BCIsWireless BCIs: Wireless BCIs More practical Embedding multiple chips More complicated thoughts Transmission with RF key requirement: keep the heat downWireless BCIs: Wireless BCIs Size: 2cm in diameter 、 8cm thick Low cost Receive Distance: 10m ~ 50mDisadvantages: Disadvantages Headache Exhausting Laziness DegenerateFuture: Future Integrate with different territory From lab to factory Nursing and medical treatmentReferences: References http://spectrum.ieee.org/biomedical/devices/the-brainmachine-interface-unplugged/0 http://www.seeingwithsound.com/etumble.htm http://www.yct.com.tw/life/98drum/98drum17.pdf http://www.libertytimes.com.tw/2007/new/may/24/today-life3.htm http://hi.ctust.edu.tw/mediawiki/index.php/%E8%85%A6%E6%A9%9F%E4%BB%8B%E9%9D%A2%28BCI%29Q&A: Q&A ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
