Psychophysical Interaction

A telemanipulation system for psychophysical investigation of haptic interaction

We report an experimental highdelity system for making psychophysical measurements on human operators performing real, virtual, and real-remote 3D haptic manipulation tasks. Operators interact with task environments through six-degree-of-freedom (6-DOF) Lorentz magnetic levitation haptic devices. This arrangement allows the operator to exert and experience real, virtual, and real-remote forces/...

Psychophysical Scaling

Psychophysical Scaling'"

their helpful criticisms of a preliminary draft of this chapter. A special word of thanks is due Dr. Stevens, u~ho, in addition to discovering seueral errors of fact and a nutnber of stylistic blunders, forced us to reconsider some of our views on various aspects of scaling. His comments coupled wzth our own misgivings resulted in a complete revision oj'the section on magnitude estimation and t...

Psychophysical Methods

When Fechner (1860/1966) introduced the new transdisciplinary research program of “Psychophysik”, his goal was to present a scientific method of studying the relations between body and mind, or, to put it more precisely, between the physical and phenomenal worlds. The key idea underlying Fechner’s psychophysics was that body and mind are just different reflections of the same reality. From an e...
