User Experience User experience is now becoming central to our understanding of the usability of technology. Today many interactive technology companies describe on their Web sites their commitment to experience-based design. There is also a trend in HCI communities to foreground experience-centered approaches to technology, a movement reflected in several(More)
In this paper, we present a new approach to interaction modelling based on the concept of information resource. The approach is inspired by recent distributed cognition (DC) literature but develops a model that applies specifically to human-computer interaction (HCI) modelling. There are of course many approaches to modelling HCI and the motivation of this(More)
BACKGROUND AND PURPOSE Knowledge of the topographic distribution of infarcts of the middle cerebral artery (MCA) may give insight into the limits of the arterial territory and infarct mechanism and may influence the decision to use thrombolytic therapy. We describe the creation of a digital atlas of MCA (DA-MCA) infarction associated with MCA branch and(More)
BACKGROUND Rocuronium, a new nondepolarizing muscle relaxant, has a rapid onset of activity and may be suitable as a component of a rapid-sequence induction of anesthesia. We evaluated a range of doses on onset and duration of effect at the larynx and the adductor pollicis and compared these characteristics with those of succinylcholine. METHODS(More)
BACKGROUND The authors evaluated the influence of temperature on the pharmacokinetics and pharmacodynamics of vecuronium because mild core hypothermia doubles its duration of action. METHODS Anesthesia was induced with alfentanil and propofol and maintained with nitrous oxide and isoflurane in 12 healthy volunteers. Train-of-four stimuli were applied to(More)
An evaluation of earcons was carried out to see whether they are an effective means of communicating information in sound. An initial experiment showed that earcons were better than unstructured bursts of sound and that musical timbres were more effective than simple tones. A second experiment was then carried out which improved upon some of the weaknesses(More)
A detailed experimental evaluation of earcons was carried out to see whether they are an effective means of communicating information in sound. An initial experiment showed that earcons were better than unstructured bursts of sound and that musical timbres were more effective than simple tones. Musicians were shown to be no better than non-musicians when(More)
In this paper we describe the Prayer Companion, a device we developed as a resource for the spiritual activity of a group of cloistered nuns. The device displays a stream of information sourced from RSS news feeds and social networking sites to suggest possible topics for prayers. The nuns have engaged with the device enthusiastically over the first ten(More)
Viewpoint is a public voting device developed to allow residents in a disadvantaged community to make their voices heard through a simple, lightweight interaction. This was intended to open a new channel of communication within the community and increase community members' perception of their own efficacy. Local elected officials and community groups were(More)
