To design handheld devices, physical comfort is one of the most crucial requirements. Recently, curved handheld touchscreens were released for enhancing comfort, but the effect has not been proved yet. Regarding user behavior with the device, it has been observed that 1/3 of user population of smartphone operate the device unimanully in a previous research. This study aimed to verify the effect of curvature on comfort when using handheld touchscreen devices. Comfort level was measured employing both the subjective rating and EMG methods. Three mock-ups of handheld touchscreen device with different curvatures were utilized. One was flat device and the others had curvatures of 400R and 100R. An experiment was conducted on tapping, typing and dragging tasks. The results indicated that curvature of the handheld touchscreen devices did not affect muscle activities, but subjective comfort level. Overall, this study suggests that there may be other design elements more important than curvature of handheld touchscreen determining comfort of touch screen use.
