Mind-controlled Quadcopter demonstrates new possibilities for people who are paralyzed
With support from the National Science Foundation, biomedical engineer Bin He and his team at the University of Minnesota have created a brain-computer interface with the goal of helping people with disabilities, such as paralysis, regain the ability to do everyday tasks.
Currently, they’re testing out their system using a flying object known as a Quadcopter, which is controlled with someone’s thoughts! For the experiments, they use both an actual flying Quadcopter and a virtual one. In both experiments, the interface is non-invasive, so there are no implants. Participants wear an electro-encephalography, or EEG, cap with 64 electrodes. When the participant thinks about a specific movement, neurons in their brain’s motor cortex produce tiny electric signals, which are send to a computer which processes them and sends directions through a Wi-Fi system to direct the Quadcopter.
He and his team chose the Quadcopter for this testing phase to keep participants engaged, but the interface is designed to help in the real world with everyday tasks, such as turning on the lights or surfing the internet.
The research in this episode was supported by NSF award #0933067, Neuroimaging of Motor Imagery for Brain Computer Interface Application, and funded through the American Recovery and Reinvestment Act of 2009.
