WASHINGTON, July 20, 2021 — Surpassing the biological limitations of the brain and using one’s mind to interact with and control external electronic devices may sound like the distant cyborg future, but it could come sooner than we think.
Researchers from Imperial College London conducted a review of modern commercial brain-computer interface (BCI) devices, and they discuss the primary technological limitations and humanitarian concerns of these devices in APL Bioengineering, from AIP Publishing.
The most promising method to achieve real-world BCI applications is through electroencephalography (EEG), a method of monitoring the brain noninvasively through its electrical activity. EEG-based BCIs, or eBCIs, will require a number of technological advances prior to widespread use, but more importantly, they will raise a variety of social, ethical, and legal concerns.
Though it is difficult to understand exactly what a user experiences when operating an external device with an eBCI, a few things are certain. For one, eBCIs can communicate both ways. This allows a person to control electronics, which is particularly useful for medical patients that need help controlling wheelchairs, for example, but also potentially changes the way the brain functions.
