- ItemMechanical control of a wheelchair by means of EEG signals(Stellenbosch : Stellenbosch University, 2018-03) Van Wyk, Ian Nicolaas; Van den Heever, David Jacobus; Stellenbosch University. Faculty of Engineering. Dept. of Mechanical and Mechatronic Engineering.ENGLISH ABSTRACT: The aim of this project was to incorporate a low cost electric wheelchair by modifying an existing self-propelled one with a neuro headset. The headset must control the wheelchair by using EEG data and motor imagery. Binary and discriminant analysis classifiers were implemented with accuracies ranging between 44% and 68.75%. It is concluded that dynamic classification has a very low accuracy compared to using pre acquired data. Also motor imagery is not very well suited when used with the Epoc+ neuro headset. The wheelchair was never constructed, however it was concluded that the listed components are sufficient to create a cheaper alternative for an electric wheelchair.
