Scrolling and pagination for within document searching: The impact of screen size and interaction style

摘要

Increasingly, users are performing more sophisticated typesof tasks, like web browsing and particularly informationsearch, across computing platforms includingdesktops/laptops, tablets, and smartphones. While muchresearch has been done to improve efficiency for each ofthese devices in the area of information search, noinvestigations have taken a pragmatic approach todetermining the real efficiency costs across current state ofthe art devices and typical browser-based searchingparadigms. We examine comparative task execution timesfor within document searching tasks under three differentconditions: varying screen sizes (desktop, tablet,smartphone), varying interaction devices (mouse &keyboard and touchscreen) and varying interactiontechniques (scrolling and pagination). In addition, weexamine components of the task: scanning, skimming andraiding and combine reading rates and KLM measures totry to predict task execution time.
