摘要

尽管它很受欢迎,但现代多点触摸界面中使用的经典捏缩放手势有缺点:具体来说,需要支持扩展范围的缩放,并且需要将内容保持在显示器的视图窗口内,这可能导致需要抓握和平移。在单手和双手捏缩放的两项形成性研究中,我们发现了模式:缩放操作遵循可预测的弹道速度曲线,用户倾向于将兴趣点移向屏幕中心。我们将这些结果应用于设计一种增强的缩放技术,称为缩放- plus (PZP),与标准的缩放行为相比,它减少了抓紧和平移操作。

Pinch-to-zoom-plus: an enhanced pinch-to-zoom that reduces clutching and panning
Despite its popularity, the classic pinch-to-zoom gesture used in modern multi-touch interfaces has drawbacks: specifically, the need to support an extended range of scales and the need to keep content within the view window on the display can result in the need to clutch and pan. In two formative studies of unimanual and bimanual pinch-to-zoom, we found patterns: zooming actions follows a predictable ballistic velocity curve, and users tend to pan the point-of-interest towards the center of the screen. We apply these results to design an enhanced zooming technique called Pinch-to-Zoom-Plus (PZP) that reduces clutching and panning operations compared to standard pinch-to-zoom behaviour.
