We present a scalable visualization technique for automatic animation of data-flow visual program execution. We also show a framework to assist programmers' browsing tasks by automatically producing the views of execution that highlight significant aspects of the program. The techniques described in this paper are based on the visual design patterns (VDPs) proposed in our VL'97 paper, which ser...

Raising computer power enables more and more realistic visual representations of real world objects. However , existing graphical systems and data formats strongly emphasize rendering aspects. Therefore, more complex objects are hard to implement, and only a subset of the object-speciic aspects can be covered by the visual representation. This paper describes a consistent object-oriented mode-l...

We describe a patient (P.S.) who, following a right prestriate lesion, reported that objects in the left visual field appeared distorted and smaller than those on the right. Other aspects of visual processing were remarkably unaffected. We carried out a series of size comparison tests using simple or complex stimuli and requiring different types of behavioural responses. We found that P.S. sign...

People have long strived to augment music sensation with visuals. Throughout history there have been many different ways to achieve this, one of them being the color organ. After seeing some of the more ancient color organs, we felt this could also be done in a digital age, so we set off to create a digital color organ of our own. A quest that would lead us through different styles of combining...

When one says “I see,” what is usually meant is “I understand.” But what does it mean to create a sense of understanding a large, complex, problem, one with many interlocking pieces, sometimes ill-fitting data and the occasional bit of contradictory information? The traditional computer science perspective on helping people towards understanding is to provide an armamentarium of tools and techn...

In studying through simulation, choosing an appropriate tool/language would be a difficult task because many of them are available. On the other hand, few research works focus on evaluation of simulation tools/languages and their comparison. This paper makes a couple of evaluations and ranks more than fifty simulation tools that are currently available. The first evaluation and ranking is in th...

This thesis is an inquiry into the creative processes of poetry and poetic expression in documentary. The practice-based element is a 60 minute video about a poet living in Exeter, UK, called James Turner. The documentary is entitled, The Knotweed Factor. This written element of the thesis contextualises the investigation as a discourse on blindness and visual impairment. There are few represen...

A large portion of the central nervous system is dedicated to vision and therefore strokes have a high likelihood of involving vision in some way. Vision loss can be the most disabling residual effect after a cerebral infarction. Transient vision problems can likewise be a harbinger of stroke and prompt evaluation after recognition of visual symptoms can prevent future vascular injury. In this ...
