Santa-Maria, Luis and Dyson, Mary C. (2008): The effect of violating visual conventions of a website on user performance and disorientation: how bad can it be?. In: DOC08 2008. pp. 47-54.

“This experiment investigates what happens to user performance and disorientation when visual conventions of a genre are violated. It also looks at what happens to the user performance and disorientation over time. Twenty-eight participants were randomly allocated to two independent groups: one was tested with a conventional website and the other with a convention-violating website. The study comprised of two parts and on each part participants were tested on a different website. Results showed that in the first part participants who used the violating site performed worse and were more disoriented than participants who used the conventional version. But the performance of the participants of the convention-violating group improved over time so that by the end of the first part performance on both groups were equivalent. In the second part performance and disorientation on both groups were equivalent suggesting that users might rapidly adapt to visual convention violations.”

Dyson, Mary C. (2004): How physical text layout affects reading from screen. In Behaviour and Information Technology, 23 (6) pp. 377-393.

“The primary objective of this paper is to critically evaluate empirical research on some variables relating to the configuration of text on screen to consolidate our current knowledge in these areas. The text layout variables are line length, columns, window size and interlinear spacing, with an emphasis on line length due to the larger number of studies related to this variable. Methodological issues arising from individual studies and from comparisons among studies are identified. A synthesis of results is offered which provides alternative interpretations of some findings and identifies the number of characters per line as the critical variable in looking at line length. Further studies are needed to explore the interactions between characters per line and eye movements, scrolling movements, reading patterns and familiarity with formats.”

Dyson, Mary C. and Haselgrove, Mark (2001): The Influence of Reading Speed and Line Length on the Effectiveness of Reading from Screen. In International Journal of Human-Computer Studies, 54 (4) pp. 585-612.

“With such a large volume of material accessible from the World Wide Web, there is an urgent need to increase our knowledge of factors influencing reading from screen. We investigate the effects of two reading speeds (normal and fast) and different line lengths on comprehension, reading rate and scrolling patterns. Scrolling patterns are defined as the way in which readers proceed through the text, pausing and scrolling. Comprehension and reading rate are also examined in relation to scrolling patterns to attempt to identify some characteristics of effective readers. We found a reduction in overall comprehension when reading fast, but the type of information recalled was not dependent on speed. A medium line length (55 characters per line) appears to support effective reading at normal and fast speeds. This produced the highest level of comprehension and was also read faster than short lines. Scrolling patterns associated with better comprehension (more time in pauses and more individual scrolling movements) contrast with scrolling patterns used by faster readers (less time in pauses between scrolling). Consequently, effective readers can only be defined in relation to the aims of the reading task, which may favour either speed or accuracy.”
