Reducing Visual Dependency with Surface Haptic Touchscreens

摘要

Interactions with current touchscreens are highly dependent on a pattern of visual feedback. Recently, researchers have developed surface haptic technology that provides haptic feedback on flat touchscreens. This presents an opportunity to add tactile responses to touchscreen interactions. This paper demonstrates that surface haptic feedback can improve the task completion time and accuracy of manipulating non-visual bullseye menus giving users greater confidence while performing selection tasks. Results suggest that haptic technology could be incorporated into applications on touchscreen devices to improve accuracy where the user's visual sensory channel is not available or is already occupied by another task.
