BCI technology has been used in a number of applications, such as wheelchair control and prostheses for the paralyzed. However, there has also been research into gaming applications of this technology. Gattis et al (2013) found that BCI users were able to use their BCI to control the mouse cursor. This research was conducted at the University of Illinois at Chicago (UIC) and focused on epilepsy patients who had lost their ability to move muscles required for arm movements. The researchers concluded that playing action game with an open hand led to an increased chance of muscle activation.
Brain computer interface (BCI) is a non-invasive system that allows direct communication between the brain and external devices such as computers, robots, or prosthetics. You can think of it like an electronic extension of your thoughts; for example, you might want to play a piano with your mind in the future.
Because BCI is so new and so far-reaching in what it can do, there are still many unanswered questions. If a neural signal turns into a computer command, this is called decoding. Decoding algorithms are very important in BCI. Some algorithms, for example, analyze the frequency of the signals from the cerebral cortex and can determine whether a signal represents “left” or “right.” Others decode images from brain signals. If BCI recognizes the word “apple,” it might flash it onto a screen.
