Abstract

Possible cardiac linked contributions were found in signals taken from an accelerometer located on a person´s head. This could provide insight into perceptual thresholds of translational whole body moves of a seated subject. The signal might create a noise floor that could explain why near-constant acceleration perceptual thresholds are seen in blindfolded and seated subjects (where only vestibular input is available) regardless of displacement or velocity of the move.
