Abstract
This paper describes the development of a brainwave controlled wheelchair. The main objective of this project is to construct a wheelchair which can be directly controlled by the brain without requires any physical feedback as controlling input from the user. The method employed in this project is the Brain-computer Interface (BCI), which enables direct communication between the brain and the electrical wheelchair. The best method for recording the brain’s activity is electroencephalogram (EEG). EEG signal is also known as brainwaves signal. The device that used for capturing the EEG signal is the Emotiv EPOC headset. This headset is able to transmit the EEG signal wirelessly via Bluetooth to the PC (personal computer). By using the PC software, the EEG signals are processed and converted into mental command. According to the mental command (e.g. forward, left...) obtained, the output electrical signal is sent out to the electrical wheelchair to perform the desired movement. Thus, in this project, a computer software is developed for translating the EEG signal into mental commands and transmitting out the controlling signal wirelessly to the electrical wheelchair.

Summary
The amount of disabled person is increasing annually in Malaysia. By referring to the statistical data that obtained from the Department of Social Welfare Malaysia, The information of the statistical data shows that the amount of physical disabled person are rising from year 2008 to 2011[1]. According to the statistics data, there are total of 657,152 people with disabilities registered in Malaysia calculated from 2009 until 2013[2] [3] [4] [5] [6]. The percentage of physically disabled persons among all the disabled person is 33%, which is the second majority of the disabled person [6] Most of these physically disabled persons are facing the difficulty to move around freely
