Thought-controlled quadcopter aimed at giving people with impaired motor ability takes a notch higher as Researchers at Zhejiang University in Hangzhou, China, develops a quadcopter that can be controlled by thought alone.
Their system relies on the commercially available Emotiv electroencephalography (EEG) headset to interpret brain activity as commands for the quadcopter. Commands are relayed first by Bluetooth to a laptop, then by wireless to the hovering aircraft.
The quadcopter's range of motion is limited by the brain activity that the EEG can pick up. A user can move the flyer forward by thinking "right", fly up by thinking "push", and turn clockwise by thinking "left". Thinking "left hard" tells the quadcopter to take off from the ground. Clenched teeth and blinking both produce a brain signal that the EEG can read, commanding the flyer to descend or to take a picture using the on-board camera, respectively. By default, that camera sends a stream of video back to the laptop, and the user can capture a still of any scene they choose by blinking four times. The system is due to be presented next month at the Ubiquitous Computing Conference in Pittsburgh, Pennsylvania.
The success of this project will likely see the disabled people control the plane they are seated in using their brain and fly. But that will of course take some years i.e in future.
