In last post (
) i explained some basic idea about BCI now i will further carry the concept of BCI for interfacing it with AI. it can do wonders in the field of human life betterment
The combination of the Brain Computer Interface and powerful Artificial Intelligence Systems is known as shared control. The need from the shared control comes from the fact that BCI depends on acquired brain signals which are quite complex in nature i.e. various human activities show complex patterns of Brain wave signals which are difficult to interpret with current signal processing algorithms so for these complex tasks we can rely on the Artificial Intelligence system let us take an example of a BCI controlled robot which has to avoid obstacles from its path. The default behavior of the robot is to move forward at a constant speed. Then, upon the reception of a mental command it turns left or right by 30 degrees. To avoid obstacle collision, the robot uses its three frontal infrared sensors. Without shared control, the robot stops in front of the detected obstacle and wait for the next mental command. If shared control is enabled, the obstacle module will make the robot turn toward the opposite direction where the obstacle is detected until the path is free.
In the case there are two simultaneous commands, one from the subject and the other from the obstacle avoidance module, the latter has the priority. Thus we leave the complex obstacle avoidance to the AI system and leave the User to give the Decision of Where to go? Which AI systems can’t do?
FUTURE ASPECTS :
Paralysis patients can be benefited to a great extent by the help of interfacing of BCI and AI because by this we can create a robot which will work according to the patients thinking. Like Robotic arm and robotic wheelchair. Thus it enables disabled people to participate in most of their daily activities.
It can also help us to overcome Situational disability where our hands are busy or are not enough. Situational disability also refers to the disability of the astronauts in the space so it can help them to make robots do work outside the spaceship according to their thinking or we can control a spaceship without human to do specific research in outer space.
One of the most exciting areas of BCI research is the development of devices that can be controlled by thoughts. Some of the applications of this technology may seem frivolous, such as the ability to control a video game by thought. If you think a remote control is convenient, imagine changing channels with your mind.
However, there's a bigger picture -- devices that would allow severely disabled people to function independently. For a quadriplegic, something as basic as controlling a computer cursor via mental commands would represent a revolutionary improvement in quality of life.
Robotic arm can also be the one of the major applications of the BCI so the arm is controlled by the brain signals. Early research used monkeys with implanted electrodes. The monkeys used a joystick to control a robotic arm. Scientists measured the signals coming from the electrodes. Eventually, they changed the controls so that the robotic arm was being controlled only by the signals coming from the electrodes, not the joystick.
A similar method is used to manipulate a computer cursor, with the subject thinking about forward, left, right and back movements of the cursor. With enough practice, users can gain enough control over a cursor to draw a circle, access computer programs and control a TV. It could theoretically be expanded to allow users to "type" with their thoughts.
