Answer :

The only difference between affective BCI and cognitive BCI is none of the above.What is Affective BCI Affective BCI is a direct brain-computer interface. An affective BCI connects the user's nervous system to a computer system and analyses the user's mental state. It is an inter-disciplinary field that encompasses brain imaging, affective computing, and robotics.

The Affective BCI system uses a bio-sensor to read the human brain's electrophysiological signals. These sensors are connected to the human scalp, where they are used to read signals produced by the human brain. These signals are then interpreted by the computer system, which can be utilized to manipulate an external device, such as a robotic arm or a wheelchair.The Affective BCI system can use signals from the human brain to control an external device in real-time. This can be accomplished using a range of input devices, including visual, auditory, and tactile stimuli.What is Cognitive BCICognitive BCI refers to the use of signals from the human brain to provide feedback to the user. The signals are detected using non-invasive sensors placed on the scalp and then transmitted to a computer system for analysis.

The cognitive BCI technology focuses on helping people who have lost motor abilities or have an incurable neuromuscular disease. The goal is to enable such people to interact with their environment in a manner that allows them to communicate and control their surroundings.A cognitive BCI can control different external devices like prosthetic limbs, computers, and cars. The primary benefit of this technology is that it allows people who cannot use their limbs to interact with their environment in a meaningful way.What is the difference between Affective BCI and Cognitive BCI?The only difference between affective BCI and cognitive BCI is that neither neurofeedback nor the number of placed electrodes on the scalp distinguishes between the two. The differences between the two are:Affective BCI detects and evaluates mental states such as pleasure, anxiety, and concentration. It also offers feedback, but it is mainly used in non-medical applications.Cognitive BCI detects and evaluates intent. Its primary goal is to aid those who are unable to move voluntarily due to neuromuscular diseases or spinal cord injury. It offers the possibility of operating devices and providing mobility.
