- Brain-computer interfaces (BCI) function by augmenting or artificially enhancing the brain’s capacity to adapt in regions where neural circuits are experiencing dysfunction.
- The goal of BCI is to substitute or rehabilitate functionality for individuals affected by neuromuscular disorders such as ALS, cerebral palsy, stroke, or spinal cord injury.
During the European Research and Innovation Exhibition in Paris in June 2006, scientist Peter Brunner showcased the remarkable capabilities of brain-computer interface (BCI) technology. He donned a cap equipped with external electrodes, enabling him to create a message by capturing and processing the electrical activity in his brain, known as electroencephalogram (EEG).
This demonstration vividly illustrated the advancing possibilities of brain-computer interfaces in communication and innovation, showcasing the potential for direct interaction between the human brain and external devices. Artificial intelligence and analytics have significantly boosted the brain-computer interfaces (BCIs) field by enhancing the analysis and interpretation of neural activity.
According to BCC Research, the global BCI market is forecasted to grow from USD 1.9 billion in 2021 to USD 3.3 billion by 2026, with a CAGR of 11.5% during the period.
If the statistics above have left you perplexed, it’s time to explore what brain-computer interfaces are. It is like a computer system that captures signals from your brain, analyzes them, and turns them into commands. These commands then make something happen on a device, letting you control things using your thoughts.
In simpler terms, it’s a technology that enables you to interact with a computer or device by just thinking about it. Let’s investigate the mechanism to understand how this duo (brain and computer) operates.
Functionality of Brain-Computer Interfaces in Business Operations
BCI operates by boosting or artificially enhancing the brain’s ability to adapt in areas where neural circuits aren’t working properly. BCI takes advantage of brain parts related to emotions and thinking that are still in good shape. It reconnects the communication between peripheral sites (like body parts) and the brain.
There are four essential components of the brain-computer interface:
The initial and crucial BCI component involves measuring intriguing brain signals through sensory modalities (scalp, MRI, and intracranial electrodes). The acquired signals undergo amplification and noise removal before being digitally transmitted to the computer.
This step means picking out the important features of signals to tell which ones we want. A computer then looks at how fast specific brain cells are firing or how quickly the brain responds (called ECoG response latencies). These details are turned into a simple format that can be used to give commands. Filtering ensures the information is accurate by eliminating unwanted signals from the body or surroundings.
The extracted features undergo translation algorithms, converting signals into commands for output devices. For example, a power decrease in a frequency band could move the cursor upward on a computer. The translation algorithm must be dynamic to adapt to changes in signal features, ensuring comprehensive coverage of device controls.
The BCI loop is finished when the device does something based on the commands it got from the features it found. It guides and controls things like moving a cursor, picking letters, or making a robotic arm move. This whole process affects and manages the feedback the user gets.
The enhancement of brain-computer interface (BCI) technology mirrors progress in algorithms, including those based on machine learning algorithms. This progress opens up more possibilities for using BCIs in healthcare, assistive technology, and how we interact with computers. Let’s explore some specific applications in these areas.
