A new approach to touch-screen set-up position for best physical workload and visibility

This study aimed to propose a new method for a bi-objective optimization. Ten student participants used a touch screen at 3 different installation heights, 3 tilt angles and with 3 button sizes. The joint angles, while using a touch screen, were measured to estimate physical workload. With the subjective screen visibility determined, the Pareto optimal solution showed ranges of 1124-1251 mm height and 44.4-67.9° tilt angle for the optimal installation of touch screens.
