Multi-Mode Brainwave Controller

Brainwave Computer Interface (BCI) is a system that provides a network of communication between the nervous system of the human brain and technical devices. Through the use of sensor, electrical impulses generated by the human brain’s activities can be inspected for thought prediction. The raw information can be extracted and programmed so that it can be used to manipulate control system such as on automation. The aim of the project is to develop a multi-mode control system on the wheelchair prototype using single EEG electrode called Mindwave mobile. The control system is programmed based on the attention and signal quality value generated from concentration, eyes blinking and eyebrow movement. The electrode placed on the forehead and transmits the electrical impulses via Bluetooth to a receiver. Results from the test done on five test subjects have shown that users can move the robot to the left, right, forward and backward direction which is programmed based on the attention and signal quality value. The use of non-invasive BCI has a lot of potential in the future. Further work on the project will help to produce an inexpensive automated wheelchair with better control over its movement. This is very useful especially to those who suffer from any physical impairment such as paralysis and stroke.
