“…In another study investigating the effects of interacting with content on handheld devices, Albers and Kim (2000) also found that traversing pages led to an increase in cognitive load. Other studies have found that increased within page navigation also has the effect of increasing task completion times (Jones et al, 1999b;Kim & Albers, 2001;Jones, Buchanan, & Thimbleby, 2003). However, this may not translate to an increase in task error rates Kim and Albers (2001).…”

The paper presents a study investigating the effects of incorporating novelty detection in automatic text summarisation. Condensing a textual document, automatic text summarisation can reduce the need to refer to the source document. It also offers a means to deliver device-friendly content when accessing information in non-traditional environments. An effective method of summarisation could be to produce a summary that includes only novel information. However, a consequence of focusing exclusively on novel parts may result in a loss of context, which may have an impact on the correct interpretation of the summary, with respect to the source document. In this study we compare two strategies to produce summaries that incorporate novelty in different ways: a constant length summary, which contains only novel sentences, and an incremental summary, containing additional sentences that provide context. The aim is to establish whether a summary that contains only novel sentences provides sufficient basis to determine relevance of a document, or if indeed we need to include additional sentences to provide context. Findings from the study seem to suggest that there is only a minimal difference in performance for the tasks we set our users and that the presence of contextual information is not so important. However, for the case of mobile information access, a summary that contains only novel information does offer benefits, given bandwidth constraints.

“…Comparable user studies have also been performed in the past, but only with desktop devices [10][11][12], old cell-phones [13] or PDAs [14], so their results are not necessarily valid for current smartphones. Previous user studies on touch-based devices (e.g., PDA or smartphone) assumed that the user does not like to scroll and, therefore, primarily focused on investigating strategies to avoid or minimize scrolling [15][16][17].…”

Abstract. Web-based graphical user interfaces (GUIs) are mostly not tailored for small devices with touchscreens, such as smartphones. There is little scientific evidence on the conditions where additional taps for navigation are better or scrolling. Therefore, we conducted a user study in which we evaluated different ways of tailoring a GUI for a smartphone. Each participant performed the same task with two different layouts of the same GUI. We collected quantitative data through measuring task completion time and error rates, as well as qualitative data through subjective questionnaires. The main result is that minimizing the number of taps is important on a smartphone. Users performed significantly better when they could scroll (vertically), instead of tapping on widget elements (tabs). This preference was also reflected in their subjective opinions.

“…The issue isn't simply one of how do we design for low resolution screens-160 x 160 pixel resolution-instead of the resolution of a standard computer monitor at 640 x 480, a reduction of resolution of 1,200 percent. Articles in Technical Communication (Kim and Albers 2002) and other journals can provide an overview of these issues and provide design guidelines.…”
