Human-Machine Interface Based on Electro-Biological Signals for Mobile Vehicles

Abstract

In this paper, a system to allow the communication between a human being and a robot, through a Human-Machine Interface (HMI), is proposed. Such HMI makes possible to use electro-biological signals, such as ElectroMyoGram (EMG), ElectroOculoGram (EOG) and ElectroEncephaloGram (EEG) to control devices like an autonomous wheelchair. An electronic board containing an environmental map has also been developed. Thus, the user selects a cell in the map, through some electro-biological signal, which is understood by the system as the place the mobile vehicle should reach. A control system to guide the robot to seek for this goal is also presented, including experimental results.
