Location-based services, which can be applied in navigation systems, are a key application in mobile and ubiquitous computing. Combined with indoor localization techniques, pico projectors can be used for navigation purposes to augment the environment with navigation information. In the present empirical study (n = 24) we explore users' perceptions, workload and navigation performance when navigating with a mobile projector in comparison to a mobile screen as indoor navigation interface. To capture user perceptions and to predict acceptance by applying structural equation modeling, we assessed perceived disorientation, privacy concerns, trust, ease of use, usefulness and sources of visibility problems. Moreover, the impact of user factors (spatial abilities, technical selfefficacy, familiarity) on acceptance was analyzed. The structural models exhibited adequate predictive and psychometric properties. Based on real user experience, they clearly pointed out a) similarities and device-specific differences in navigation device acceptance, b) the role of specific user experiences (visibility, trust, and disorientation) during navigation device usage and c) illuminated the underlying relationships between determinants of user acceptance. Practical implications of the results and future research questions are provided. Copyright 2012 ACM.

Projector phones, handheld game consoles and many other mobile devices increasingly include more than one display, and therefore present a new breed of mobile Multi-Display Environments (MDEs) to users. Existing studies illustrate the effects of visual separation between displays in MDEs and suggest interaction techniques that mitigate these effects. Currently, mobile devices with heterogeneous displays such as projector phones are often designed without reference to visual separation issues;therefore it is critical to establish whether concerns and opportunities raised in the existing MDE literature apply to the emerging category of Mobile MDEs (MMDEs). This paper investigates the effects of visual separation in the context of MMDEs and contrasts these with fixed MDE results, and explores design factors for Mobile MDEs. Our study uses a novel eye-tracking methodology for measuring switches in visual context between displays and identifies that MMDEs offer increased design flexibility over traditional MDEs in terms of visual separation. We discuss these results and identify several design implications. © 2011 ACM.

This article reports on the experience of conducting the program committee (PC) meeting for the IEEE VR 2009 conference in Second Life. More than 50 PC members from around the globe met virtually over a two-day period to decide which papers to accept for presentation at the conference. Survey responses from 42 of the PC members indicate generally positive feelings toward this meeting format, although several alterations will help improve interaction between attendees in future meetings. © 2009 IEEE.

22nd British HCI Group Annual Conference on People and computers: Culture, Creativity, interaction, BCS HCI 2008

As computing is changing and becoming increasingly social in nature, the role of emotions in computing has become ever more relevant and commercial. Emotions are central to culture, creativity, and interaction. The topic attracts more and more researchers from a range of multidisciplinary fields including design, gaming, sensor technologies, psychology and sociology. The need for discussion, exchange of ideas, and interdisciplinary collaboration is ever-increasing as the community grows. This workshop will meet requirements of individuals working in the field, giving them a podium to explore different aspects of emotion in HCI, raise questions and network with like-minded people on common subjects. The workshop will focus around working group sessions, and will use predominantly small group work, rather than being presentation-based. © 2008 The Author Published by the British computer Society.

Zoomable user interfaces in scalable vector graphics

Zoomable user interfaces in scalable vector graphics

5th Annual Conference on Scalable Vector graphics, SVG Open 2007

作者： Rotard, Martin Eissele, Mike Van Putten, Raul Ertl, Thomas Researcher in Computer Graphics and Human Computer Interaction University of Stuttgart Visualization and Interactive Systems Institute Universitaetsstr. 30 Stuttgart 70569 Germany

Zoomable user interfaces are an evolutionary outgrowth of graphical user interfaces. In this paper we propose a zoomable user interface based on Scalable Vector graphics. Three-level zooming is proposed as a new paradigm to combine different zooming functionalities in a common interface and support zooming within the window manager. This helps to unify zooming techniques of different applications. To meet the demand of efficient and easy navigation on a user interface, several novel interaction techniques are shown that further support the integration of three-level zooming within the underlying presentation system. For mobile small-screen devices, where the benefit of zooming user interfaces is even higher, the proposed system can be operated with simple pen tap or tap and drag operations. We also present a prototypical implementation, which demonstrates how applications based on the SPARK toolkit can transparently benefit form the proposed technology.

We present a real-time simulation of spray painting incorporated into a VR environment as an alternative training system for ship-building industries. The system allows the user to try out a painting work on life-size structures with a spray gun. Our goal is to provide a trainee realistic painting experience in real-time as well as to represent the thickness of the deposited paint on the surface for evaluation of his performance. The Gaussian model is used for a painting deposition model, and texture mapping technique is utilized to provide efficient visual feedback. We also present effective collision detection methods for a volume of spray paint particles. ©2007 IEEE.

Emotions in HCI: an affective e-learning system

Proceedings of the HCSNet workshop on Use of vision in human-computer interaction - Volume 56

作者： Robin Kaiser Karina Oertel Fraunhofer Institute for Computer Graphics Rostock Human Centered Interaction Technologies Germany

This paper presents results of a master thesis at the Fraunhofer Institute for computer graphics Rostock (IGD-R) at the department for human-Centered interaction. Using an emotion recognition sensor system, an e-learning system was enhanced with affective abilities. By taking certain actions, the user is supported to handle negative emotions, which should enable a better learning as well as a greater satisfaction. The affective communication and actions are encapsulated by an Affective Component, which was implemented as a prototype and evaluated at a first glance.

The effect of field-of-view, display type and user role on the experience of simulator sickness and presence in users of a virtual environment was investigated. A PC based assessment instrument was created to administer the Presence, Immersive Tendencies and Simulator Sickness questionnaires. The field-of-view was found to be the major determinant of both simulator sickness and presence.

Professor John Belcher developed a series of short videos with animation and text of selected experiments to properly demonstrate the phenomena of electromagnetism. Such 3D animations are visually compelling, instilling in the student both a sense of wonder about the phenomena and a mental model of why and how it works. The products of these approach includes video clips of demonstrations, 3D animations of these demonstration which display time changing field-lines as a guide to understanding their dynamical effects and Java applets which allow the student to actively construct and animate 2D field lines for varying configurations of sources. These technologies are also implemented to develop animations for Faraday's insights, using video clips.
