In this paper, we show that people frequently return to previously-visited regions within their documents, and that scrollbars can be enhanced to ease this task. We analysed 120 days of activity logs from Microsoft Word and Adobe Reader. Our analysis shows that region revisitation is a common activity that can be supported with relatively short recency(More)
We describe a method for applying gain to events reported by scrolling input devices such as scroll wheels. By treating document length as an input to our gain functions, the method allows rapid document traversal regardless of document length; it also allows slow and precise scroll control at shorter distances. An initial experiment characterises four(More)
Flashcard systems typically help students learn facts (e.g., definitions, names, and dates), relying on intense initial memoriztion with subsequent tests delayed up to days later. This approach does not exploit the short, sparse, and mobile opportunities for microlearning throughout the day, nor does it support learners who need the motivation that comes(More)
Flick scrolling is a natural scrolling method for mobile touch devices such as the iPhone#8482;. It is useful not only for its performance but perhaps even more so for its ease of use and user experience. Tilt scrolling instead uses the device's tilt to determine the rate of scrolling, which offers several potential interaction advantages over touch(More)
Navigating to files through a hierarchy is often a slow, laborious, and repetitive task. Recent lab studies showed that file browser interface augmentations, such as Icon Highlights and Search Directed Navigation, have the potential to reduce file retrieval times. However, for this potential to be realised in actual systems, further study is necessary to(More)
We propose MultiScroll, a general purpose hybrid scrolling technique that uses multitouch input to allow for a combination of rate based scrolling for navigating short and medium distances and zero-order scrolling for navigating large distances. The design challenges of supporting both scrolling modes on mobile devices are discussed, including the use of(More)
