我们展示了两种不同的“闪-刹”技术，这种技术不仅允许用户通过轻弹触摸屏来触发运动，还允许用户随后通过改变静止手指的压力来调节滚动速度。这些技术进一步利用了巨大车轮的隐喻，为用户提供了在线摩擦控制。我们描述了一个有限状态机，它模拟了各种轻弹交互风格，有或没有压力控制。我们报告了一项初步用户研究的结果，该结果表明，对于中远距离滚动，“弹-刹”技术需要的手势活动比标准轻弹更少。该技术的两种变体之一速度更快，但准确性并不低于最先进的弹射。用户还表示，比起标准的轻弹，他们更喜欢“一闪一停”，并认为这种方式更有效率。我们指出初步调查结果提出的一些悬而未决的问题。
We present two variants of Flick-and-Brake, a technique that allows users to not only trigger motion by touch-screen flicking but also to subsequently modulate scrolling speed by varying pressure of a stationary finger. These techniques, which further exploit the metaphor of a massive wheel, provide the user with online friction control. We describe a finite-state machine that models a variety of flicking interaction styles, with or without pressure control. We report the results of a preliminary user study that suggests that for medium to long distance scrolling the Flick-and-Brake techniques require less gestural activity than does standard flicking. One of the two variants of the technique is faster, but no less accurate, than state-of-the-art flicking. Users also reported they preferred Flick-and-Brake over the standard flick and judged it more efficient. We indicate some pending issues raised by the results of this preliminary investigation.
