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...

The recent deployment of many seismometers and occurrences of earthquakes in Japan revealed explosive nature of earthquakes. There have been a few reports that earthquakes and eruption of helium gas took place simultaneously, but there has been no hypothesis to co-relate each other. Recently, a new idea that atomic hydrogen can generate energy somewhat between chemical reaction and nuclear reac...

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...

The debate of life on Mars centers around the source of the globular, micrometer-sized mineral carbonates in the ALH84001 meteorite; consequently, the identification of Martian processes that form carbonates is critical. This paper reports a previously undescribed carbonate formation process that occurs on Earth and, likely, on Mars. We identified micrometer-sized carbonates in terrestrial aero...

The purpose of this review is to describe various geological and chemical factors that are controlling the fluoride concentration in soil, rocks, water, air, plants, animals and food stuffs. Further to discuss well established method that is used as the standard methods of analysis. Rock, Soil, Water, air, plants, animals, foodstuffs all contain fluoride in widely varied concentration. Industri...

Abstract Micrometer sized stromatolitic structures called Frutexites are features observed in samples from the deep subsurface, and hot-spring environments. These comprised of fine laminations, columnar morphology, commonly consist iron oxides, manganese and/or carbonates. Although a biological origin is invoked, few reports have shown direct evidence their association with microbial activity. ...
