Controlling Home Appliances through Thought Commands

Brain-Computer Interfaces (BCI) is a field which has shown rapid advancement over the past few decades. With the availability of low-cost electroencephalography (EEG) signal acquisition devices, it is becoming more feasible to develop hands-free environmental control systems which can be used for everyday use. These systems may be used as an assistive technology for disabled individuals or as an alternative form of control for healthy individuals. Hands-free environmental control systems often lack user-friendliness and intuitiveness due to the difficulty of mapping the users' intentions, to control commands that can be used to control the appliances in a 3D environment. Therefore, this paper reports on an ongoing research to develop a hands-free environmental control system based on P300 responses of EEG signals of a user. The proposed solution does not use a screen for visual feedback, therefore, it improves the intuitiveness and user friendliness than existing solutions.
