Toyota Motor develops wheelchair controlled by brain waves
01 Jul 2009
A Toyota Motor Corp collaboration, the BSI-Touota Collaboration Centre (BTCC), has succeeded in developing a wheelchair controlled by brain waves using a new signal processing technology for brain machine interface (BMI) application.
This technology used is one of the fastest technologies in the world, controlling a wheelchair using brain waves in as little as 125 milliseconds (one millisecond, or ms, is equal to 1/1000 seconds.
The major advantages of the new technology are that the wheelchair driver's commands for left and right turns and forward motion are processed every 125 milliseconds by analysing brain waves using signal processing technology.
The brain-wave analysis data is displayed on a screen in real time, giving neuro-feedback to the driver for efficient operation.
This technology is expected to be useful in the field of rehabilitation, and for physical and psychological support of wheelchair drivers.
BTCC was established in 2007 by Riken, an independent administrative institution, as a collaborative project with Toyota Motor Corporation, Toyota Central R&D Labs, Inc. and Genesis Research Institute, Inc.
