Technology Puts Mind Over Body

Quadriplegics face many obstacles, such as full or partial loss of movement and/or speech, but new technology called the Brain Computer Interface (BCI) could improve the quality of life for victims by responding to brain signals and enabling control of certain electrical devices.

The BCI response is becoming ever more realistic thanks to continuing work at the Brain Computer Interface Lab Department of Biomedical Engineering Principle Researcher, Center of Biomedical and Robotics Technology, Mahidol University.

Lab director Yodchanan Wongsawat, speaking after the Thailand seminar on Broadband Deployment and Universal Service Obligation, organised by the Telecommunications Research and Industrial Development Institute (Tridi) and the International Telecommunication Union (ITU), said BCI recognises brain signals and uses them to control electrical or communication devices and can even assist in repairing human cognitive or sensory-motor functions.

The technology use sensors to detect brain activity and amplify signals, which can then be processed into messages or commands to aid decision-making.
