Adaptive Presentation Supporting Focus and Context

mc at ecs.soton.ac.uk This paper focuses on how content adaptation is provided in adaptive and adaptable hypermedia systems. Questions that we investigate are: How focus and context can be supported by content-adaptation techniques? Are there any techniques that can be easily generalized to adapt the content of generic Web pages without requiring much effort from the author of the pages? How different adaptation techniques should be compared? We propose a new technique of adaptive presentation of Web content, which derives from fisheye views. This technique applies adaptation by modifying the scale of the visual elements in Web pages. We present an adaptable Web application that applies the technique to a set of real-world pages. We also identify existing adaptation techniques that relate to the proposed technique and examine their strengths and weaknesses. Finally, we present and discuss the results of a pilot study which compared our fisheye technique against stretchtext adaptation. The results indicate that our technique is promising while they give valuable feedback about future work. 1
