Abstract
Compared with the traditional control panel, touch screen provides better user experience for the operator. The heights and angles of touch screen were the main factors in structure design. A device with adjustable heights and angles were designed to provide different heights and angles in this study, and 12 participants with different heights took part in the experiment. The subjective score about heights and the preferred angles of touch screen were recorded during the experiment. Data analyzing results shown the preferred heights were 90 cm–125 cm from ground and the preferred angles at each height can be calculated by the equation y = −0.7345 x + 224.9816. The verification tested the patterns and shown the accuracy. The results can provide reference for the structure design of touch screen on standing posture.
