Brain Control of Wheelchair

The system analyzes thought patterns and translates them into wheelchair movement in a fraction of a second

Male Speaker: Researchers in Japan have developed a brain-machine interface that allows for control of a wheelchair using thought alone. In this video we despite government affiliated research unit RIKEN. The thought patterns of the research have been picked up by electroencephalography or EEG senses method on is ahead. Toyota is relate to a laptop computer interpreted and turns into control signals for the wheel chair. The system was developed by RIKEN and Toyota Motor, Toyota Central R&D Labs and Genesis Research Institute. That the gentle is three hours training per day for week, the system can be trained to a particularly uses thought patterns and achieving accuracy rate of 95 percent. The interpretation process takes as little as thousands of second, which increase on the several seconds of our systems and when things go wrong an emergency stop can be performed by puffing out of cheek to activated safety sensor. Plans to use the technology in a range of applications are already under way. First uses will likely center on the fields of medicine and nursing care management with the BMI interface decoding brain waves related to imaginary hand and foot control. But researchers are confident that they can extend its use to detection of brain waves generated by various mental states and emotions with further research. Earlier this year researchers at Honda Motor reported success in development of a BMI system that allows a person to control a robot through thought alone. The system allows a researcher to think one of several predefined movements, such as the robot lifting its right arm, and hopefully have the robot follow through with the same action. Honda said its system achieves a 90 per cent success rate. Japanese car makers have built-up expertise in robotics from their development of highly automated production lines, and have been seeking to channel some of this knowledge into humanoid robots. Japan faces a rapidly aging society and home-help robots are seen as a potential answer to an anticipated shortage of health care workers in the years ahead.
