A simple and inexpensive technique for the measurement of head sway.
The paper presents a relatively simple and economic system for measuring human head sway. The recording device is a downward looking 35-mm still camera which photographs a flashing infrared light emitting diode (LED) that is mounted on the top of the head. The pictures so obtained are then digitized and fed into a computer for stabilometric analysis. If desired the film can be advanced continuously at an adjustable speed to obtain a deconvoluted recording.
