This paper investigates the state of monotony to determine if relatively simple instrumentation can measure whether or not a driver is likely to be in or approaching this state. First the Mackworth clock test, a well known protocol for producing a monotonous state is reproduced in a laboratory based experiment. A number of physiological indicators and electroencephalograph (EEG) are monitored during the experiment. The state of monotony is verified by continuous EEG recording, a baseline is determined by examining pre and post event activity. A range of possible peripheral measures are then also simultaneously recorded such as Galvanic Skin Response (GSR), electrocardiogram (EKG), electrooculograph (EOG), electromyograph (EMG) and 3D head tilt (using a custom built accelerometer based device) together with user inputs. Preliminary results from a test pool of eight subjects indicates that some of these peripheral physiological measures may contain markers that correlate well with alpha and theta EEG activity, thus indicating the state of monotony.
