This paper discusses visual information representation from the perspective of human comprehension. The distortion viewing paradigm is an appropriate focus for this discussion as its motivation has always been to create more understandable displays. While these techniques are becoming increasingly popular for exploring images that are larger than the… (More)
A fundamental issue in user interface design is the effective use of available screen space, commonly referred to as the screen real estate problem. This paper presents a new distortion-based viewing tool for exploring large information spaces through the use of a three-dimensional pliable surface. Arbitrarily-shaped regions (foci) on the surface may be… (More)
As the use of 3D information presentation becomes more prevalent the need for effective viewing tools grows accordingly. Much work has been done in developing tools for 2D spaces which allow for detail in context views. We examine the extension of such 2D methods to 3D and explore the limitations encountered in accessing internal regions of the data with… (More)
It is a diicult problem to display large, complex graphs in a manner which furthers comprehension. A useful approach is to expand selected sections (foci) of the graph revealing details of subgraphs. If this expansion is maintained within the context of the entire graph, information is provided about how subgraphs are embedded in the overall structure.… (More)
As the ability to accumulate and generate very high resolution image data explodes so does the need for appropriate access tools. We present a multi-scale or detail in context viewing tool for image data.
We explore the application of our visual access distortion technique to a block of temporal data created from a sequence of landscape event based information. This type of access extends the possibilities of visual exploration for temporal and spatial interrelations in a data set.
We describe a novel solution to the problem of occlusion in viewing three-dimensional data. A distortion function is used to clear a line of sight to previously obscured interior elements .
