The purpose of this study was to verify the performance of recently developed body-worn sensor packs against 3D motion analysis of trunk and lower-limb movements. Five sensor packs, each consisting of rate gyroscope and two 2-D accelerometers controlled by a microprocessor were attached to the trunk, thighs, and shanks of an able bodied subject. A 6-camera… (More)
Auditory icons – or environmental sounds – have the potential to convey information by non-verbal means quickly and accurately. In addition, human listeners are quick to determine many qualities of an auditory object, such as location, distance, size, and motion, from acoustics of the signal. An experiment tests these two coupled assumptions in a controlled… (More)

(as well as seminar participants in various places) for helpful comments. We are particularly grateful to two anonymous referees, whose perceptive remarks led to major improvements in the paper. Abstract Analysts should correct for distributional differences before undertaking local progressivity comparisons between income tax or tax and benefit schedules.… (More)
