Hong Kong SAR Government Information Network news on the 29th, the Chinese University of Hong Kong has successfully developed a "brain-computer interface" system that can convert brain waves into traditional Chinese characters, so that the whole body can not talk patients, have the opportunity to open the heart window.
According to the briefing, the patient only needs to wear a wireless brainwave receiver with 16 contact surfaces and face the Chinese stroke input interface on the computer screen. Thinking about the strokes he wants to write, the receiver can receive the instructions of the strokes. Write out one by one. It is reported that this system uses the T9 stroke input method that is similar to the most commonly used mobile phone in Hong Kong. It only requires five kinds of strokes: horizontal, vertical, æ’‡, æº, and hook. When the system is in operation, the user only needs to input several strokes at the beginning of the word, and the system will automatically search for possible words for the user to select.
At present, simple short sentences or words like “Helloâ€, “Good afternoonâ€, “Chinese Universityâ€, etc., from acceptance, recognition to completion of the translation process, take 3 to 5 minutes, and the accuracy is due to the environment and users. There is a difference in emotions, with a maximum of 70% to 80%. The research team stated that the system is doubtlessly dozens of times slower than direct speech, sign language, or handwriting. However, for severely paralysed patients, they can be said to be in a world completely isolated from the world and the new system has broken through obstacles. They can express themselves, even if they are simple phrases, it is a valuable “zero breakthroughâ€.
The Hong Kong Special Administrative Region Government Information Technology Director Lai Hsi-yu said that similar research projects have been conducted in the field and that brainwaves can be converted into English subtitles. The Chinese University project is the first device to input Chinese.
This research project is one of the nine funded projects of the Office of the Director of Information Technology of the Hong Kong Special Administrative Region's “Accessibility Assistance Technology R&D Fundâ€. The project exhibition will be held at the Hong Kong Central Library from May 11th to 14th.
