People are talking about brain-computer interfaces (BCIs) a lot lately. These gadgets let users control devices just by thinking about it. For some, this sounds like a dream come true. For others, it's a bit of a nightmare. A closer look at public opinions over the last decade shows a mix of excitement and worry. While the idea of controlling things with your mind i...
The world of brain-computer interfaces (BCIs) is making waves. These tools have the power to bring back speech for people who have lost it due to neurological issues or injuries. BCIs can turn brain signals into text. But text alone can't capture the full richness of human speech. It misses out on things like tone and the ability to hear oneself speak. A recent brea...
Wearable tech is taking a leap forward. It is now possible to turn thoughts into art. Brain-computer interfaces (BCIs) are stepping out of labs and into the world of art. These interfaces read brain signals and turn them into visual and physical expressions. Two cool projects show how this works. The first project is a dress with a brain-sensing headband. This dr...
The brain is a complex organ that generates electrical signals. These signals can be captured and analyzed using electroencephalography (EEG). One big challenge in brain-computer interfaces (BCI) is figuring out which EEG signals are important and which ones are just noise. This is where feature selection comes in. It helps to pick out the useful bits of information ...
Imagine controlling a computer just by thinking about it. Sounds like science fiction, right? Well, it's not. In 2024 and 2025, some amazing surgeries using brain-computer interfaces (BCIs) made big news. These surgeries let paralyzed people use computers with just their thoughts. This isn't new. People have been talking about mixing humans and machines since the 196...
Imagine losing the ability to use your hands. For many people with paralysis or diseases like ALS, this is a daily reality. Scientists have been working on a solution: neuroprostheses, which are artificial hands, arms, or legs that could restore mobility. However, these devices have struggled to match the precision of real hands. Now, a new study has found a way...
