Neural Interface Devices Image courtesy of IBVA Technologies Incorporated. Description Neural Interface Devices allow users to take advantage of small electrical signals generated by their bodies to control their computers or electrical devices attached to their computers. The small electrical signals can be acquired either directly or indirectly.
Direct methods involve surgically implanting micro probes in the user's body.
The implant can be located in the user's brain or at the end of an amputated limb, depending on the application. Direct neural interfacing technology is still in the development stages. Indirect methods of obtaining signals are more desirable than direct methods because surgery is not required. These indirect neural signals can be obtained from the user's muscles, eye movement or brain waves. The contracting and relaxing muscles produce the electrical signals which are detected by the sensors.
