This hat turns thoughts into writing: No need for hands!
Controlling technology through thoughts, once a sci-fi phenomenon, is now one step closer to becoming a reality. With the dazzling advancement of artificial intelligence, the idea of directly connecting the human brain to computers is making concrete strides on the scientific stage.
Systems that translate thoughts into text have, until now, typically required invasive methods like brain implants or functional magnetic resonance imaging (fMRI). But researchers at the University of Technology Sydney have succeeded in achieving this without any surgery.
THE HAT TRANSFORMS THOUGHT INTO TEXTThe developed headgear-like device tracks the wearer's brainwaves and converts these signals into written text. The device utilizes two artificial intelligence models to analyze brainwaves. The first model uses deep learning algorithms to translate brain signals into targeted words.
The second model acts as a large language model to ensure the accuracy of the words extracted and correct errors in EEG decoding. The research team states that the system currently operates at approximately 75 percent accuracy, but they aim to increase this to 90 percent.
While similar systems were previously only possible with brain implants, this new technology operates without any invasive intervention, making it much more accessible and practical for users.
In 2023, another system notably enabled a stroke patient to regain communication using a brain-computer interface and an AI-powered voice generator. Last year, a brain chip was implanted in a human skull for the first time as part of Elon Musk's Neuralink project.
Experts believe such technologies are particularly important for improving the quality of life of stroke patients. Mohit Shivdasani, from the Department of Bioelectronics at the University of NSW, explains that scientists first analyze a medical condition and then use the technology to restore affected functions. "There's no limit to what's possible," Shivdasani says, highlighting the potential for future development.
