3 Applications of Brain-Computer Interface

Brain-computer interface (BCI) enables a person to control an external device using brain signals.

Research on brain-machine interface began in the 1970s by Jacques Vidal, Vidal's 1973 paper marks the first appearance of the expression brain-computer interface in scientific literature.

3 Applications of brain-computer interface

1. Robotic limbs and wheelchairs

2. Wireless headsets

3. Spellers

1. Robotic limbs and Wheelchairs

By supplying a real-time neural feedback loop that rewires the brain, BCIs are capable of restoring movement, mobility, and autonomy for paralyzed and disabled patients, heightening their quality of life.

In more chronic cases, robotic devices and limbs are integrated.

Blackrock Neurotech

Helps patients regain tactile function, movement of their limbs and prosthetics, as well as the ability to control digital devices solely from thought.

Neuralace, Its latest project, is a flexible, hexagonal mesh patch designed to conform to the fissures of the brain.

Precision Neuroscience

Precision Neuroscience is approaching brain-computer interface systems with a surgically implanted brain chip that’s minimally invasive and fully reversible, to treat neurological diseases.

Neuralink

Neuralink builds an implantable, brain-computer interface capable of translating thought into action. Launched in 2016, the private venture claims its neural device allows people with paraplegia to regain movement and restore vision to those born blinds.

2. Wireless Headsets

Headsets are a way to deliver a non-invasive approach to brain-computer interfaces. Some boost productivity and enhance focus, as seen with:

Neurable’s Enten

Neurable's Enten boosts productivity and enhances focus.

IpsiHand

IpsiHand system by Neurolutions: restores motor functions to an individual’s upper extremities following a stroke.

3. Spellers

Non-verbal individuals, who may be stuck in a “locked-in” state following a stroke or severe injury, can use eye movement for computer-augmented communication.

A Brain-Computer Interface (BCI) provides a non-muscular communication method via brain signals.

All those BCI examples are still in the research phases or started human clinical trials.
