Acceptable Dwell Time Range for Densely Arranged Object Selection Using Video Mirror Interfaces
説明
We evaluated an acceptable dwell time range to decrease erroneous selections using a video mirror interface. In this interface, users select a target object by moving his/her palm and dwelling on the object. We focused on a situation wherein objects are densely arranged and users must select a target object from these objects. The effects of dwell time, object size, and distance between objects on the object selection task were experimentally evaluated. The results indicated that a dwell time of 0.3i¾?s is the most appropriate to decrease both erroneous selections and unpleasant experiences. The results of this study can contribute to defining an effective basis for dwell time for selection operations in gesture-based interaction systems.
