Effects of Visual Field Restriction on the Stability of Human Head Position During Walking.

Abstract

The stability of human head position during walking was investigated, using angular velocity sensors, with emphasis on the effects of restriction of the visual field. The results (i) confirm the stability of head position during normal walking and (ii) demonstrate the importance of information from the peripheral visual field, as seen by differences in the amplitude of head movements. The effects of searching behavior on the head movements are discussed.
