There has been limited consideration of teenagers (defined as 12-19 year olds in this work) as participants and end-users in Child-Computer Interaction and mainstream HCI communities. Teenagers reside in a fascinating and dynamic space between childhood and adulthood, and working more closely with teenagers within HCI may bring great insights and benefits. This paper provides an overview of tee...

HCI is diverse, exciting, and expanding. Inevitably the HCI community pulls itself in different directions, sometimes with the result that some worthwhile research is under-valued. This paper explores the systemic issues, and makes some constructive suggestions.

Music and other art based methods should play a significant role in the HCI field when designing with children, taking the developmental stage of the children into consideration. Music has been neglected in the design process in HCI research, while there is a lot of meaningful research in social and educational studies. HCI research has concentrated more on technological products and technologi...

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...

This volume is published and copyrighted by its editors. 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...

Hot carrier thermalization is a major source of efficiency loss in solar cells. Because of the subpicosecond time scale and complex physics involved, a microscopic characterization of hot carriers is challenging even for the simplest materials. We develop and apply an ab initio approach based on density functional theory and many-body perturbation theory to investigate hot carriers in semicondu...
