Recently, touch-sensitive screen has been in widespread use as interface with high usability in public facilities. However, it is pointed out that installation height and screen tilt angle are not inequable for its user because there is a difference of the body type. In this study, for the purpose of taking the knowledge applicable to the design guide of touch-sensitive screen, we investigated the relationship between installation position of touch-sensitive screen and operability. Moreover, we measured maximum torque ratio of upper limb to examine the effect of installation position to arm burden. We asked examine to operate on touch-sensitive screen in nine conditions. Three conditions depend on the height of center of touch-sensitive screen (height of shoulder, elbow and lower back), and the other three conditions depend on the screen tilt angel (0°, 45°, 90°). The result showed that installation height and screen tilt angle of touch-sensitive screen have an influence on pointing time and arm burden. From this study, we suggest the installation positions that are easy to operate and lightly-loaded.
