BCIs use electrodes placed on the scalp or implanted directly in the brain to detect and interpret brain activity. This information can then be used to control external devices, such as prosthetic limbs, computers, or even haptic feedback devices.
By using haptic technology in conjunction with BCIs, researchers have been able to develop systems that allow individuals to control external devices through their thoughts and receive feedback through touch or other sensory stimuli. For example, a person with a prosthetic limb could use their thoughts to control the movements of the limb and receive feedback through vibrations or pressure, allowing them to sense the position and movement of the limb.
While haptic technology and BCIs have shown promising results in laboratory settings, their practical applications for reading minds and communicating thoughts are still in the early stages of development and require further research and testing.
