Introduction To Brain Computer Interface
It’s a very complex term to understand at first. However, by breaking it down – we get three words: brain, computer and interface. So, in simple terms, it is an interface, a direct interaction route between the brain’s electrical act and an outer gadget, mainly a robotic limb or a computer. This computer-based approach analyzes the commands given by the brain and then translates them into commands that are forwarded to the output gadget to bring out the desired activity. It just completes the void between an external gadget and your brain.
Making a presentation by only using your thoughts might be achievable with the help of the Brain-computer interface (BCI).
Kinds of BCI
The BCIs are classified into three groups-
This type is considered the safest and most inexpensive type of device. Though it can only detect “fragile” human brain signs because of the skull’s obstruction, It is detected with the help of electrodes put on the scalp.
In this type, gadgets are implanted into the skull on the top of the human brain.
In this type, devices are implanted straight into the human brain by necessary surgery. These are special devices that capture brain signals.
Earlier, it focused on aiding the paralyzed people by controlling their thoughts using the control assistive gadgets. However, new cases are coming up now and then.
Now, BCIs can improve the cognitive performance of an individual. It can tell about an individual’s attention level, whether he’s paying attention or not to the meeting or tasks. And depending on that, it will activate an alert.
It is highly adaptable. It can adjust your office’s lighting according to your stress level. Plus, if you are detected with drowsiness, it would also prevent driving a car.
Brain-Computer interface is not a perfect technology. Nevertheless, technology is gradually shifting into the market. There are a lot of tech firms and start-ups striving to build a more accurate, budget-friendly and safer brain-computer interface. Even though there are a lot of challenges to overcome, it will be thrilling to start building it.
