The aim of this paper is to develop algorithms to measure motion features by investigating concepts which are commonly used to describe movement characteristics in both research studies and everyday life: impulsivity and smoothness. We also aim to implement such definitions in our developing environment VisNet and finally test if they can effectively measure impulsivity and smoothness in the sa...

Within the field of HCI there are a number of preferred approaches towards design. As within other disciplines, these approaches are often irreconcilable. We explore the possibilities of using ethics as a way to bridge the gap and re-establish the design focus of doing good towards the user. This is the idea of ‘justice’ to aid improved design. According to Aristotle, justice is classed as a vi...

Accepted for publication 26 March 1991 Abstract The oesophageal acid clearance time was evaluated in 10 healthy volunteers of 'small' boluses of 0 5 and 1 ml and 'minute' boluses of 0-05 and 0*1 ml 0.1 N HCI, as well as 0-1 and 1 ml 0*01 and 0.001 N HCI. Swallow rate was normalised at q 60 seconds. For 0.1 ml 0.1 N HCI, acid clearance time was also measured for swallow intervals of q 30 and 120...

This reports research on users’ attitudes towards and use of GSM devices and discusses the implications these have for the future evolution of hand-held devices. It argues that current usage patterns suggest that there i s unlikely to be a widespread convergence of information accessing devices and person to person communication devices. It also argues that the latter devices and their associat...

IS continuance is important for IS providers to increase both their revenues and profits, and to achieve success. With the penetration of SNS into people’ lives, SNS has attracted the attentions of IS researchers and become a hot topic. This study develops a model to explore the factors determining individuals’ continuous intention and use of SNS. Based on 221 useful questionnaires, the researc...

Designing virtual personal assistants that are able to engage users in an interaction have been a challenge for HCI researchers for the past 20 years. In this work we investigated how a set of vocal characteristics known as “conversational style” could play role in engaging users in an interaction with a virtual agent. We also examined whether the similarity attraction principle influences how ...

but I prefer to use needs and desires because I feel these terms better frame discussions from the user's perspective, and work better when discussing the parallel between an organization's perspective and that of the user of its products.

Much attention has been paid in HCI to techniques for designing systems that conform to the tasks users wish to carry out. It is often the case that such approaches rely on identifying the combinations of commands a user will be expected to issue and information thay will need to access, and designing an interface with appropriate temporal behaviour. Many fields of activity, however, are highly...
