An Introduction to 3D User Interface Design

3D user interface design is a critical component of any virtual environment (VE) application. In this paper, we present a broad overview of three-dimensional (3D) interaction and user interfaces. We discuss the effect of common VE hardware devices on user interaction, as well as interaction techniques for generic 3D tasks and the use of traditional two-dimensional interaction styles in 3D environments. We divide most user interaction tasks into three categories: navigation, selection/manipulation, and system control. Throughout the paper, our focus is on presenting not only the available techniques, but also practical guidelines for 3D interaction design and widely held myths. Finally, we briefly discuss two approaches to 3D interaction design, and some example applications with complex 3D interaction requirements. We also present an annotated online bibliography as a reference companion to this article

Sources of Computer Metaphors for Visualization and Human-Computer Interaction

This chapter is devoted to finding sources for metaphors of computer visualization and human-computer interaction. Computer metaphor is considered the basic idea for the development of interfaces, visualization views, and scenarios of visualization and interaction. Global metaphors map the main design idea. These ideas depend on global events and changes in society, art, and science. In the “pre-computer” era, such ideas formed the basics of cartography, engineering drawings, and drawing function graphs on the Cartesian plane. When designing visualization and interactive systems, computer metaphors use “magic features” beside analogies with daily life. Nowadays ideas of visualization are often based on “gamification.” This approach presupposes creating tools that provide software engineers with an interface similar to that of computer games. In this chapter, ideas drawn upon fairy tales, science fiction books, fantasy films, and other similar spheres are considered as sources of computer metaphors. Such metaphors are very interesting when designing visualization systems based on virtual reality

Spatial metaphors of the ancient world: theory and practice

Group C-2 of the Excellence Cluster 264 Topoi Space and Metaphor in Language, Cognition, and Texts is dedicated to the study of spatial metaphors and their functions in texts of different genres, languages, and epochs. This outline of the work of group C-2 takes as its point of departure and theoretical framework a general linguistic typology of spatial metaphors. This outline is followed by a series of case studies ranging from wisdom texts and philosophical treatises to tragedy and from Ancient Egyptian to Shakespearean English. These examples are aimed at illustrating both the challenges and the possibilities of the study and interpretation of spatial metaphors in their respective contexts

Working in the dark

Professional engineers work as experts who influence the work of others. They rarely have direct contact with the products of an enterprise. They work with analogues such as graphs, algorithms and simulations, and engage in discussions in specialized languages, which develop alongside the technological changes they promote or oppose. The engines of linguistic development are metaphors and analogies, however there is no system for creating them. Some metaphors and analogies become so familiar that they are treated as literal terms or literal explanations and become embedded in engineering language games. The field of electrical engineering offers hosts of examples. Students wishing to practice in engineering will need to become fluent in the language games of the profession. The haphazard evolution of language games offer students little help. As with acquisition of any language, repeated rehearsal is vital and practice in playing specialised language games is a primary part of engineering education

Usability dimensions in collaborative GIS

Collaborative GIS requires careful consideration of the Human-Computer Interaction (HCI) and Usability aspects, given the variety of users that are expected to use these systems, and the need to ensure that users will find the system effective, efficient, and enjoyable. The chapter explains the link between collaborative GIS and usability engineering/HCI studies. The integration of usability considerations into collaborative GIS is demonstrated in two case studies of Web-based GIS implementation. In the first, the process of digitising an area on Web-based GIS is improved to enhance the user's experience, and to allow interaction over narrowband Internet connections. In the second, server-side rendering of 3D scenes allows users who are not equipped with powerful computers to request sophisticated visualisation without the need to download complex software. The chapter concludes by emphasising the need to understand the users' context and conditions within any collaborative GIS project. © 2006, Idea Group Inc

Convening Publics: The parasitical spaces of public action

About the book: Political Geography is a core subdiscipline of Human Geography, the Handbook of Political Geography will provide a highly contextualised and systematic overview of the latest thinking and research. Edited by key scholars, with international contributions from acknowledged authorities on the relevant research, the Handbook of Political Geography is divided into six sections: - Scope and Development of Political Geography - key debates; the geography of knowledge; conceptualisations of power; and conceptualisations of scale - Geographies of the State - state theory; territory and central local relations; legal and judicial geographies; borders; and states and nature - Participation and representation - citizenship; space; electoral geography; place; media public space; and social movements - Political Geographies of Difference - class; nationalism; gender, sexuality ; and culture - Geography Policy and Governance - regulation; welfare; urban space; planning, environment - Global Political Geographies - geographies of imperialism; post-colonialism; globalization; environmental politics; international relations; war; and migration The Handbook of Political Geography will be the standard work, widely used and highly-cited, by all scholars with an interest in politics and space

Post-place branding as nomadic experiencing

This paper introduces post-place branding in the context of the post-representationalist turn in marketing research by drawing on Deleuze and Guattari’s (A thousand plateaus: capitalism and schizophrenia, University of Minnesota Press, Minneapolis, 1987) theory of nomadology. By engaging critically with fundamental concepts in the place and destination branding literature, post-place branding offers an alternative perspective to entrenched definitions of subjectivity, place, and event experiencing, by effecting a paradigmatic shift from processing monad to nomad, from event as symbolic structure to micro-events, from pre-constituted place to spacing in the process of deand reterritorializations. Post-place branding is illustrated by re-imagining the brand architectural components of the experiential events of 70,000 Tons of Metal and The Boiler Room. The analysis culminates in a metaphorical modeling exercise that draws nomadological guidelines for brandcomms’ message strategy

Directional adposition use in English, Swedish and Finnish

Directional adpositions such as to the left of describe where a Figure is in relation to a Ground. English and Swedish directional adpositions refer to the location of a Figure in relation to a Ground, whether both are static or in motion. In contrast, the Finnish directional adpositions edellä (in front of) and jäljessä (behind) solely describe the location of a moving Figure in relation to a moving Ground (Nikanne, 2003). When using directional adpositions, a frame of reference must be assumed for interpreting the meaning of directional adpositions. For example, the meaning of to the left of in English can be based on a relative (speaker or listener based) reference frame or an intrinsic (object based) reference frame (Levinson, 1996). When a Figure and a Ground are both in motion, it is possible for a Figure to be described as being behind or in front of the Ground, even if neither have intrinsic features. As shown by Walker (in preparation), there are good reasons to assume that in the latter case a motion based reference frame is involved. This means that if Finnish speakers would use edellä (in front of) and jäljessä (behind) more frequently in situations where both the Figure and Ground are in motion, a difference in reference frame use between Finnish on one hand and English and Swedish on the other could be expected. We asked native English, Swedish and Finnish speakers’ to select adpositions from a language specific list to describe the location of a Figure relative to a Ground when both were shown to be moving on a computer screen. We were interested in any differences between Finnish, English and Swedish speakers. All languages showed a predominant use of directional spatial adpositions referring to the lexical concepts TO THE LEFT OF, TO THE RIGHT OF, ABOVE and BELOW. There were no differences between the languages in directional adpositions use or reference frame use, including reference frame use based on motion. We conclude that despite differences in the grammars of the languages involved, and potential differences in reference frame system use, the three languages investigated encode Figure location in relation to Ground location in a similar way when both are in motion.
