The measurement of grip-strength in automobiles: A new approach to detect driver's emotions

This experimental study investigated grip-strength as a new non-invasive method to detect emotion, A positive emotion (happiness) and a negative emotion (anger) were examined regarding their influence on grip-strength applied to the steering wheel. Results confirmed and extended preliminary findings of LaMont (2000): Subjects showed increased grip-strength while driving a car when strong emotions like anger or happiness were induced. Implications for further research as well as for praxis will be outlined.
