Imagine being able to compose an email, send a text, or control a computer just by thinking. This futuristic vision is rapidly moving toward reality with the development of Brain-Computer Interfaces (BCIs). BCIs establish direct communication between the brain and external devices, potentially revolutionizing how humans interact with technology. But how close are we to a world where we can type with our thoughts? Let’s explore the current state of BCIs, their challenges, and when we might see widespread adoption.
At their core, BCIs capture and interpret brain signals to translate them into commands for a computer or other digital devices. This is typically done using:
- Electroencephalography (EEG): Non-invasive sensors placed on the scalp detect electrical activity in the brain.
- Intracortical Implants: Tiny electrodes surgically implanted in the brain provide more precise signal detection.
- Near-Infrared Spectroscopy (NIRS): Uses light to measure brain activity changes based on oxygen levels.
By analyzing these signals, BCIs can identify patterns associated with specific thoughts, such as the intent to move a cursor or select a letter…
