Since the initial publication in 1994, Coordination Theory (Malone and Crowston, 1994) has been referenced in nearly 300 journal articles, book chapters, conference papers and theses. This chapter will analyze the contribution of this body of research to determine how Coordination Theory has been used for user task analysis and modelling for HCI. Issues that will be addressed include: I) how th...

This study examines the effects of interacting with voice interfaces in an ingroup or an outgroup accent, for both native and non-native but competent English speakers. In a balanced, between-subjects experiment, (N = 96), ingroup and outgroup participants were randomly paired with one of two types of computer speech outputs: 1) computer speech output accent which matched the participants’ acce...

In this paper we discuss the different elements of the gaming experience and their relation to other concepts within HCI. The objective is to showcase how the different elements that form the gaming experience can be used to understand further issues regarding user experience. The objectives of games are, after all, to provide players with a positive experience. Understanding the elements that ...

This paper discusses previous work in developing intervention apps for sustainability that are designed to be cool and improve user engagement. While much work has been carried out by the HCI community in sustainability, particularly energy consumption; little has been done to improve interaction with this relatively mundane but serious topic to engender a compelling and cooler experience. Usin...

Recent advances in heat flux measurement have produced a robust thermopile heat flux sensor intended for use in hypersonic flight research. The High Temperature Heat Flux Sensor (HTHFS) is capable of operation at sensor temperatures up to 1050°C with simultaneous measurement of thermopile surface temperature and heat flux. Customization of the sensor design allows implementation in a broad rang...

A growing number of HCI models provide insights into humanand system-oriented aspects of design artefacts. Experience with modelling in practice suggests that the more difficult design problems are cross-disciplinary, and there is a need to be able to integrate both the results and the process of HCI modelling. This document reports on the techniques for integration that have been developed and...

This topic introduces the concept of Hot Swapping DC power buses and why hotswapping has become a mainstream requirement, particularly in the telecommunications industry. Several methods of implementing hot swap will be provided along with the pros and cons of each method. Finally, a hot swap design utilizing a Hot Swap Power Manager will be presented for a typical -48V telecom
