Air+touch: interweaving touch & in-air gestures

摘要: We present Air+Touch, a new class of interactions that interweave touch events with in-air gestures, offering unified input modality expressiveness greater than each alone. demonstrate how air and are highly complementary: is used to designate targets segment while gestures add expressivity events. For example, user can draw circle in the tap trigger context menu, do finger 'high jump' between two touches select region text, or drag 'pigtail' copy text clipboard. Through an observational study, we devised basic taxonomy Air+Touch interactions, based on whether component occurs before, after touches. To illustrate potential our approach, built four applications showcase seven exemplar created.
