用意念“说”出想说的话 上海脑机接口技术取得突破 为失语患者带来福音

Core Insights - The collaboration between Shanghai YanSi Brain-like AI Research Institute and Huashan Hospital has achieved a breakthrough in brain-computer interface technology, enabling real-time decoding of brain signals to display intended Chinese phrases [1] - This technology has significant implications for patients with speech impairments, such as those suffering from ALS and stroke [1] Group 1: Technological Advancements - The brain-computer interface technology allows for information exchange between the brain and external devices, with applications in healthcare, wellness, and education [1] - The development of a brain electric model, akin to a pre-trained model like ChatGPT, enables precise interpretation of brain signals, particularly for complex languages like Chinese [2] - The model has achieved over 83% accuracy in recognizing Chinese initials and over 84% in recognizing finals, marking it as an industry leader [2] Group 2: Clinical Applications - Clinical trials have demonstrated that the brain electric model can extrapolate from a training set of 54 Chinese characters to interpret 1,951 commonly used characters, showcasing a high extrapolation rate of 1:36 [3] - The model can decode a complete Chinese sentence within half a second, theoretically allowing for unlimited sentence length [3] - This technology not only aims to restore language abilities for speech-impaired patients but also opens avenues for controlling smart devices and interacting with the metaverse through thought [3]
