Well, this project heavily relies on the flexing of muscles for human-computer interaction, instead of fingers. Say a child is handicapped in that they don't have functioning hands or even legs. Well, why not construct controllers such that ANYONE can use them? The cool aspect of the EMG/EEG car is that the car can easily be controlled, with little effort, and without the need to press a button or have a lot of dexterity! In fact, the idea of the project can be expanded to include other muscles in the body ( and perhaps better methods for interpreting EEGs ) in order to implement other buttons!
