title = "SegTouch: Enhancing touch input while providing touch gestures on screens using thumb-to-index-finger gestures",
abstract = "Insufficient input modality on touchscreens causes icons, toolbars and mode switching steps required to perform different functions. Although various methods are proposed to increase touchscreen input modality, touch gestures (e.g., swipe), usually used in touch input, are not provided in previous methods (e.g., Force Touch on iPhone 6s). This still restricts the input modality on touchscreens. Hence, we propose SegTouch to enhance touch input while providing touch gestures. SegTouch uses thumb-to-index-finger gestures, i.e., the thumb slides on the index finger, to define various touch purposes. Based on a pilot study, the middle and base segments on the index finger are suitable input areas for SegTouch. To observe how users leverage the proprioception and natural haptic feedback from index finger landmarks to perform SegTouch, different layouts on the index finger segments were examined in the eyes-free. Including the normal touch without thumb-to-index-finger gesture, SegTouch provides 9 input modality and touch gestures on the screen, so novel applications are enabled.",
