New GyroSet Wheelchair Control System employs Wireless Headset to do away with Joystick and this can be a great blessing for those paralyzed neck down.

GyroSet, is a system developed by Márton Juhász and Now Technologies and is an Android tablet-powered system which enables a person to use his head to direct the wheelchair.
The users wear a head set that can find the position of the head and this data is sent to a tablet which interprets the movements and sends signals to the electric wheelchair. The system is inexpensive to implement and obliterates the need of the joystick from the front of the face.
