- Abstract:
-
To address error recognition problems created by mental fatigue when a human subject partakes in a single motor imager process for a long period of time, a visual information assisted EEG (electroencephalograph) human-machine interactive control system was proposed. The system produces a new sample updated strategy, with the‘state’of the eyes being recognized by the improved Adaboost algorithm in real-time and the recognition result being used to decide which EEG signal to update as the model parameter for human-machine interaction. An experiment on controlling an intelligent wheelchair off a fixed trajectory with a‘8’glyph was undertaken. The results show that visual information is adopted effectively by the intelligent wheelchair users to avoid the fatique-related error recognition problem with good levels of efficiency; thus proving that the interactive method is feasible.
