Recently the whole society tends to attach importance to humanity and human life. One’s KANSEI such as feeling, sense, taste, preference and so on has been utilized to product design. Consequently the design technique has been adopted which the function or specification is decided according to measurement and analysis of KANSEI. And an approach to those technique by KANSEI information processing and KANSEI engineering has been focuse on and is discussed in this paper.

Nishikawa found that error frequency in the Uchida-Kreapelin Test wss very low and constant, and errors occurred independently of each other. Kodama and Masuyama made a prototypical system to conduct the same test using a personal computer and a mouse. In this report, we carried out spectral analysis using the error occurrence data of Kodama and Masuyama, and found that a certain personal computer system and the test paper.

This paper proposes a new device for knee and hip joints CPM/rehabilitation. The machine has three D.O.F. mechanism to follow complicated human joint motion, direct-teaching system to implement therapist motion directly to the device, and impedance control to decrease load to joints. Also, the device is able to measure those joints angle and their load torque.

To propose a comfortable design of VDT (visual display terminal) workstation, vertical eye movements were analyzed while performing word processing task using three different types of workstation. The vertical gaze direction is an useful index in the field o visual ergonomics, because direction became higher while viewing display as the distance between a display and a keyboard increased. The higher gazing direction causes strong eye irritation. Thus the display should be set lower and closer to the keyboard to realize a comfortable VDT workstation.

A laboratory study was conducted to determine the effects of position and the bed height when lifting a patient from a lying to sitting position. Eight student nurses lifted a female volunteer who served as the patient. Three different standing positions at bed side and two different bed heights were used. The experiments were done with and without patient assistance while each nurse lifted.
A pair of forceshoes, which can measure the left and right ground reaction forces, was developed. The forceshoes were able to measure the ground reaction forces independently at the toe and heel. For each lifting task, normal reaction forces and the standing position of nurses were measured to determine the center of balance. The data thus obtained were used to analyze the center of balance, the impulse and the duration of lifting.
On the whole, it was shown that (1) the lifting time appeared to be decreased when the nurses stood at the upper part rather than lower part of the bed. (2) The loci of center of balance formed a strait line and it was shown that moderate level of lifting exertion to sit the patient upright was required at a high bed height, standing toward the upper part of a bed and with patient assistance.
