Playing online multiplayer games entails matching oneself with other players. To do so, players must typically employ various types of communication tools that are part of the game or of game-external matching services. But despite the centrality of these tools they receive little attention in discussions of game design and game HCI. This paper seeks to rectify this situation by presenting an i...

In the design of interactive systems, overall performance issues tend to receive less attention than provision of functionality. As a result, systems may not always offer performance improvements to their users. In this paper we present some proposals for methods based on the use of application-specific critical parameters, i.e., performance parameters that measure how well the system serves it...

Introduction We report on two of our own studies, each of which has built on a laboratory based finding and explored if and how the effects played out in everyday settings. In each, we fou...

The importance of the domestic soundscape as a context for technological interventions has received little attention in HCI research. In this paper, we discuss how an ethnomethodological soundwalk method facilitated design principles for a phatic technology probe for seniors living alone. Taking soundscape concepts as a starting point, we suggest that the soundwalk works much like a breaching e...

What is culture in HCI? This article presents how the term culture has been used and discussed by authors in the discipline. Since culture is a complex concept, there is no aim to establish the term as a fixed definition in this paper. Instead the purpose is to enlighten some previous discussions and uses in order to ask questions, encourage new discussions and give motivation for searching com...

acrylic resin denture bases undergo dimensional changes during polymerization. injection molding techniques are reported to reduce these changes and thereby improve physical properties of denture bases. the aim of this study was to compare dimensional changes of specimens processed by conventional and injection-molding techniques.sr-ivocap triplex hot resin was used for conventional pressure-pa...

Over recent years, the study of games and players has become an established domain with HCI research. However, while a range of methods has been employed within this area, questions remain as to how to develop in-depth understandings of players and the contexts they play within. Drawing upon the social sciences, this paper proposes case studies as an additional methodology for player research. ...

In this introductory chapter, we describe the key lessons from an earlier HCI Educators’ conference, held in Limerick in 2006, the outcomes of which led to the theme of HCIEd 2007 – Creativity: Experiencing to Educate and Design. The paper discusses the lessons leant around four key questions: nature vs. nurture: can creative invention be taught; what tools and methods are there to help student...

Gamification has been widely accepted in the HCI community in the last few years. However, the current debate is focused on its short-term consequences, such as effectiveness and usefulness, while its side-effects, long-term criticalities and systemic impacts are rarely raised. This workshop explores the gamification design space from a critical perspective, by using design fictions to help res...

Papers in HCI play different roles, whether to inspire, solve industrial problems or further the science of HCI. There is a potential conflict between the different views, and a danger that different forms of validity are assumed by author and reader — deliberately or accidentally. This paper reviews some of the issues in this complex area and makes
