摘　　要：在多屏幕环境中,实现跨屏幕内容分享的现有技术忽视了对空中手势的利用.为验证空中手势,实现并部署了一套跨屏幕界面共享系统,支持使用空中手势完成屏幕间界面内容的实时分享.根据一项让用户设计手势的调研,实现了“抓-拖拽”和“抓-拉-放”两种空中手势.通过对两种手势进行用户实验发现:用空中手势完成跨屏幕内容分享是新颖、有用、易于掌握的.总体上,“抓-拖拽”手势用户感受更好,但“抓-拉-放”手势对于复杂情景的通用性更好;前者更适合近屏场景,推荐在屏幕相邻且间距不大、操作距离近时使用;后者更适合远屏场景,推荐在目标屏幕间有间隔屏幕或相距较远时使用.因此,将两种手势相结合使用更为合理.Mid-air gestures have been largely overlooked for transferring contents among multiple screens. For verification, a cross-screen interfaces sharing system is designed, which enables users to move interface content across screens by gestures in real time. According to the user-designed gesture survey, two mid-air gestures,“grab-drag” and “grab-pull-drop”, are implemented. User experiment shows that they are novel, useful, and easy to learn. In general,“grab-drag” provides better user experience, while “grab-pull-drop” is more versatile in complex scenarios. The former gesture is more suitable when the two screens are adjacent and the operation distance is short too;while the latter suits are better in away-from-screen scenarios, when there is a third screen among target screens or screens are widely spaced. Therefore, a combination of the two gestures will be a rational solution.
