A Study on Workspaces for Retrieval and Placement Using Visual Characteristics and Muscle Load

Abstract

The standards of a working area are usually proposed to be determined by standard size of body and the range of movement. This study examined the proper operation area in view of vision and movement load while working through measuring the visual characteristics and muscle load in movement while working. The experiment was conducted through the assembly of model products and the retrieval and placement of parts with changed arrangements of parts within various working areas. As the result, the following was revealed : 1) Accordingly, as the working area is extended, the view stopping time decreases significantly, and the horizontal arrangement of parts is more efficient than vertical arrangement in terms of visual recognition. 2) It was identified that the muscle load caused by retrieval and placement varies according to the angle and the distance. 3) It was proven that the working area is divided by the muscle load and proper part arrangement area for particular conditions.
