It is impossible to design systems which are appropriate for all users and all situations. We believe that a useful technique is to have end users tailor their systems to match their personal work practices. This requires not only systems which can be tailored, but a culture within which users feel in control of the system and in which tailoring is the(More)
At EuroPARC, we have been exploring ways to allow physically separated colleagues to work together effectively and naturally. In this paper, we briefly discuss several examples of our work in the context of three themes that have emerged: the need to support the full range of shared work; the desire to ensure privacy without giving up unobtrusive awareness;(More)
In this paper, we seek to contribute to the Ubiquitous Computing agenda by focusing on one of its earliest, but most difficult, design ambitions - making technology "invisible in use". We draw on field studies of domestic life as this domain is becoming increasingly important for new technologies and challenges many of the assumptions we take for granted in(More)
In order to understand some problems associated with work-flow, we set out an analysis of workflow systems, identifying a number of basic issues in the underlying technology. This points to the conflation of temporal and dependency information as the source of a number of these problems. We describe Freeflow, a prototype which addresses these problems using(More)
A powerful way of reaching through technology is to use analogy to make the technology transparent by exploiting the user's familiarity with other situations. However, analogy has a number of roles in user interface design in addition to the one of helping the user understand the system. In this paper we consider some of these roles and their relationship(More)
Design Rationale emphasises working with explicit representations not only of possible design solutions, but also of the reasons and processes behind them. Although the arguments for using Design Rationale are compel~mg, there is still very little experience of applying the current approaches in practice. To explore its use in a practical setting we have(More)
Estimation of tumour proliferation may allow the design of individualised radiotherapy schedules to optimise response. This prospective study correlates the tumour proliferation rate of cervical carcinoma with response to conventional radiotherapy. The potential tumour cell doubling rate (Tpot) was estimated following flash labelling of the tumours in vivo(More)
We assert that the product of user interface design should be not only the interface itself but also a rationale for why the interface is the way it is. We describe a representation for design based around a semi-formal notation which allows us explicitly to represent alternative design options and reasons for choosing among them. We illustrate the approach(More)
