HyperAT: HCI and Web Authoring
We review HCI problems with hypertext, and for authoring World Wide Web documents in particular. We suggest that a framework is required to understand the usability issues, and that these issues cannot be seen as psychological or computing: they are multi-disciplinary. We discuss HyperAT, a protorype authoring tool, being implemented to test these ideas.

Improving mobile internet usability
Mobile internet technologies, such as WAP, are important for pervasive, anytime, anywhere computing. Although much progress has been made in terms of technological innovation, many of mobile internet systems are difficult to use, lack flexibility and robustness. They give a poor user experience. Evaluation and theoretical analysis of usability combined with innovative design can achieve significant improvements in user performance and satisfaction. Using such multidisciplinary methods explains the negative reactions to WAP, and — more constructively — suggest ways of developing more effective and efficient devices and services.

The music is the message
the music being played by her tiny mobile audio appliance. She's standing waiting for a train. Other commuters swarm nearby, headphones on, listening in more muted ways to the soundtracks they've chosen to accompany today's episode of their daily routine. Mobile music players—iPods, Walkmans and the like—are exciting for those of us involved in thinking about the future of mobile devices and services. Like the mobile phone—increasing numbers of which also sport a music player—these are gadgets that people actually desire, and aspire to own. They have vast storage capacities, increasingly sophisticated processors and pleasing, effective mechanisms for users to control their func-tionality. From click and jog wheels to high-resolution color displays, these players are far from being the impoverished devices that typified mobile platforms just a few years ago. And there are hundreds of millions of them in circulation—Apple sold five million in the first quarter of 2006 alone. But at the same time, these marvelous mobiles could be seen as an obstacle to the bright futures dreamt up in the research labs. How will people be able to make use of the ubiquitous computing infrastructure being envisaged, the anytime, everywhere access to information and services, when they are immersed in digital sound bubbles of their own choosing? Some mobile listeners, at first sight, certainly appear cut off. Another scene: A young man stares out of a train window, watching the long green fields flash by. His eyes are bright but still; his gaze betrays a mood of deep reflection. Listening to music on expensive , noise-reducing headphones, what is he thinking? Is he sadly contemplating a lover left or anticipating a longed-for meeting at his destination? How can we design mobile services that will fit this context? The conventional clumsy beeps, vibrations, and attention-seeking displays seem out of place. What opportunities are there to build more emphatic systems , systems to enhance the music and environmental experience or to provide ways for the listener to later reflect on the situations they've lived through in relation to the music they've heard? At other times, though, these sound bubbles seem more permeable, don't they? One of the photos of people listening to music available on a popular image-sharing site is entitled " Listening to Kim's iPod and talking to Joe! " A teenager holds a mobile phone to her left ear while wearing the distinctive white music-player headphones. Chatting and …

A digital library of conversational expressions: helping profoundly disabled users communicate
Digital libraries are for everyone. This paper describes the development of a digital library for a user who has a profound physical disability that means she cannot communicate verbally, and cannot use conventional communication tools.

Shape representation using space filled sub-voxel distance fields
Voxelisation is the process of converting a source object of any data type into a three-dimensional grid of voxel values. This voxel grid should represent the original object as closely as possible, although some inaccuracies will occur due to the discrete nature of the voxel grid representation. In this paper we report our ongoing research into methods for representing objects as voxelised distance fields, in particular we report fast methods for accurate distance field production. A review of current alternative voxelisation methods is also given.

Volumes of expression: artistic modelling and rendering of volume datasets
This paper presents the design and implementation of artistic effects in modelling and rendering of volume datasets. Following different stages of a volume-based graphics pipeline, we examine various properties of volume data, and illustrate how expressive and non-photorealistic effects can be implemented. We demonstrate that the true 3D nature of volume data makes it particularly applicable for this use, allowing the addition of complex effects at the modelling stage as well as during rendering.

Wikifying your interface: facilitating community-based interface translation
We explore the application of a wiki-based technology and style of interaction to enabling the incremental translation of a collaborative application into a number of different languages, including variant English language interfaces better suited to the needs of particular user communities. The development work allows us to explore in more detail the design space of functionality and interfaces relating to tailoring, customization, personalization and localization, and the challenges of designing to support ongoing incremental contributions by members of different use communities.

Operating system directions for the next Millennium
We believe it is time to reexamine the operating system's role in computing. Operating systems exist to create an environment in which compelling applications come to life. They do that by providing abstractions built on the services provided by hardware. We argue that advances in hardware and networking technology enable a new kind of operating system to support tomorrow's applications. Such an operating system would raise the level of abstraction for developers and users, so that individual computers, file systems, and networks become unimportant to most computations in the same way that processor registers, disk sectors, and physical pages are today.
