Playing video games using your mind or thoughts seems like a dystopian imagination, but it looks like it is possible anytime soon.
Scientists from a lab in Austin have created a wearable brain-computer interface (BCI) in which people can control the screen without using their fingers.
The users only need to wear an electrode cap that controls the signals emitted from their brains.
The experiments on brain-computer interface have been taking place for years, but have never given a satisfying result.
The scientists have to face lots of difficulties, such as extreme costs, slow learning abilities, and the inability to trace fragile signals and irregularities.
Brain-Computer Interface:
After decades of trying, engineers from the University of Texas at Austin have tried something different by breaking the regular methods.
They have created a decoder with the help of signal experts, and then trained the software to bend toward every newcomer.
The technology behind BCI is based on two different techniques: Generic Recentering, which centers itself without any external help, and Personally Assisted Recentering, which adds a light, optional tweak from the user.
Eighteen volunteers put both approaches through their paces, and the fully automated method matched even the slightly customised version in those two tasks, which means the system worked perfectly fine on unfamiliar brains without any extra setup.
The principle of electrode caps is based on electroencephalography, a decades‑old technique that tracks low-voltage changes on the scalp.
Traditional BCI force analysts used to track each other’s optimal signal patterns for hours, but the decoder skips that search by leaning on the expert’s neural footprint as a starting point. Then it pokes the centre of the data cloud until the new signals line up.
Generic Recentering is used for nudging automatically, whereas Personally Assisted Recentering helps in correcting a handful of mistakes.
Such an improvement in software development allows scientists to save their energy and time to train AI models, which usually takes a lot of time to learn.
Generally, many games, including those racing games, require rapid anticipatory turns and quick reflexes, which are not possible if the processor is slow.
Importance Of the Brain-Computer Interface:
Uses of the Brain-Computer Interface are a kind of luxury for a person who is physically able, but it can be very useful to a person who is differently abled or cannot move their body, such as those with spinal‑cord injuries or stroke‑related movement loss.
A study from the Milan group envisaged that regular BCI practice can improve neural plasticity as the brain knacks for rewiring itself. Hence, the onboarding process becomes much smoother than expected.
Challenges:
One of the biggest current problems that BCI faces is the slow training process of its AI system. It takes plenty of time to train their AI for even smaller tasks.
The engaged scientists believe that the key to scaling up the process is shortening the gap between initial contact and effective control. The researchers believe the gap can be squeezed in minutes from hours.
According to the researchers, the main motive behind the technology is to help people in their daily lives. These electrode caps can become as important as the heart-rate straps that we use today.
Patients can start training as soon as they wear the cap and strengthen their unused neural circuits while playing a racing game, which is more fun than traditional therapy.
The Future:
Devices that capture and analyse brain waves are still in the initial stages. Still, they are unable to trace small muscle twitches, signal drifts over long sessions, and regular scrutiny.
With the latest improvement of the decoder, it’ll be very easy to track different minds and how they operate.
Probably it is not that far away, we can really place a racing game on our screens, wearing an electrode cap, and without any remote or keyboard in our hands.
