User's motion for shape perception using CyARM

Abstract

We have developed a new sensing device, named by "CyARM". CyARM is one of Active Perception device, based on activeness of human perception. In order to clarify information for shape perception using CyARM, an experiment had conducted. Results of this experiment show that shapes with sharp edges are identified easily, but shapes with smooth edges are identified with greater difficulty. In other words, the subjects perceived changes in distance from the sensor to the object as object edges. Furthermore, from the results of multi-dimensional scaling, it is suggested that object shapes perceived by the subjects were classified according to the sharpness of the edge and by the ratio of height and width. In addition, motion analyses were conducted. The result shows, it is suggested that user tend to swing arm to front arm mainly in motion of lateral direction. © 2009 Springer.
