“ It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them. ”

Zanella, A., Carpendale, M. S. T. and Rounding, Michael (2002): On the effects of viewing cues in comprehending distortions. In: Proceedings of the Second Nordic Conference on Human-Computer Interaction October 19-23, 2002, Aarhus, Denmark. pp. 119-128.

“As a community, human-computer information and interface designers have tended to avoid use of fisheyes, and multi-scale presentations with their attendant distortion because of concern about how this distortion may lead to confusion and misinterpretation. On the other hand, for centuries, hand-created information presentations have made regular use of distortion to provide emphasis and actually enhance readability. Is the lack of use in computer presentations because thus far in our computational uses of distortion we have failed to provide adequate support that allows people to comprehend the manner in which the information is being presented? We describe a study about relative difficulty in reading distortions that investigates the effect of the use viewing cues such as the cartographic grid and shading on people's ability to interpret distortions. We look at two interpretation issues: whether people can locate the region of magnification and whether people can read the relative degree of magnification of these regions. We present the findings of this study and a discussion of its results.”

Carpendale, M. S. T. and Montagnese, Catherine (2001): A framework for unifying presentation space. In: Marks, Joe and Mynatt, Elizabeth D. (eds.) Proceedings of the 14th annual ACM symposium on User interface software and technology November 11 - 14, 2001, Orlando, Florida. pp. 61-70.

“Making effective use of the available display space has long been a fundamental issue in user interface design. We live in a time of rapid advances in available CPU power and memory. However, the common sizes of our computational display spaces have only minimally increased or in some cases, such as hand held devices, actually decreased. In addition, the size and scope of the information spaces we wish to explore are also expanding. Representing vast amounts of information on our relatively small screens has become increasingly problematic and has been associated with problems in navigation, interpretation and recognition. User interface research has proposed several differing presentation approaches to address these problems. These methods create displays that vary considerably, visually and algorithmically. We present a unified framework that provides a way of relating seemingly distinct methods, facilitating the inclusion of more than one presentation method in a single interface. Furthermore, it supports extrapolation between the presentation methods it describes. Of particular interest are the presentation possibilities that exist in the ranges between various distortion presentations, magnified insets and detail-in-context presentations, and between detail-in-context presentations and a full-zooming environment. This unified framework offers a geometric presentation library in which presentation variations are available independently of the mode of graphic representation. The intention is to promote the ease of exploration and experimentation into the use of varied presentation combinations.”
