Week 14 a.k.a. Control Computer Without Hands... Or Feet... Or Anything Really
We usually take our health for granted, right until the moment we lose it. And when it happens, we may lose ability to do certain, previously easy, things, such as using computer for example. This is Week 13 of SPEAIT2021K course and I would like the IT world to be accessible for everyone. BCI, which is short for Brain-Computer Interface, is a technology that allows a person to control computer with his brain. It is not eye-tracking device, no - instead, brain activity is monitored with electrodes attached to person's head, it is analyzed with the help of AI and transformed to commands. Research in this field began in 1970s, when researchers in UCLA measured brain activity with EEG (electroencephalography) and then analyzed ERPs (event related potentials), or simply brain responses. Our brain controls our body by sending electric impulses through our nerve system to certain muscles, the nerve impulse affects actin and myosin proteins and the muscle contracts. Those electric impulse
