Abstract
This study investigated the effect of pseudo-haptic feedback that is rendered based on visuo–haptic interaction with a touchscreen, on a visual memory task during image browsing. Pseudo-haptic feedback on a touchscreen is rendered by changing the control/display ratio (C/D ratio), which is the ratio of the movement of the user’s finger (control) to the movement of the background image on the display (display). By using this method, we compared the performances of the visual memory task under two visual modification conditions (i.e., with and without dynamic C/D ratio modification) and two interactivity conditions (i.e., with an interactive system and with an autonomous system). The experimental results showed that the figures associated with the pseudo-haptic feedback significantly remained in memory, and the participants showed the best performance of the visual memory task when using interactive scrolling with dynamic C/D ratio modification. These results show that pseudo-haptic feedback on touchscreens affects a user’s memory during image browsing.
