Recent Methodological Opportunities in Online Hypermedia – a Case Study of Photojournalism in Singapore

This methodological paper reviews the recent work done by photojournalists in Singapore who have leveraged on the use of multimedia to create meaning-rich narratives of the social situations they investigate. Using an online multimedia project recently launched by journalists and photojournalists in Singapore, I will show how photographers'/photojournalists' expertise, knowledge and combination of text and photographs serve to exemplify the opportunities that hypermedia affords to sociologists, and argue that hypermedia presentations are particularly useful in extending auto/biographical narratives, encouraging collaborative research, as well as interrogating the everyday social lives of our informants.Visual Sociology, Hypermedia, Online Methods, Singapore, Photojournalism, Visual Methods, Photography

Experiencing Audio Recorded Research (EARR): Giving Voice to Qualitative Poster Presentations

Qualitative research emphasizes and honors the words of participants in an effort to generate meaning and knowledge, yet participants’ voices are rarely heard beyond data collection and analysis. We explore the potential to share participants\u27 voices when disseminating research through audio - enhanced poster presentations. Technological advancements in multimedia could revolutionize poster presentations, especially for qualitative research. We describe the history of audio guides and how they can be applied to the dissemination of qualitative research. We also introduce the Experiencing Audio Recorded Research (EARR) Model to facilitate designing a multisensory approach to qualitative data dissemination through integrating audio technology into presentations

The sweet smell of success: Enhancing multimedia applications with olfaction

This is the Post-Print version of the Article. The official published version can be accessed from the link below - Copyright @ 2012 ACMOlfaction, or smell, is one of the last challenges which multimedia applications have to conquer. As far as computerized smell is concerned, there are several difficulties to overcome, particularly those associated with the ambient nature of smell. In this article, we present results from an empirical study exploring users' perception of olfaction-enhanced multimedia displays. Findings show that olfaction significantly adds to the user multimedia experience. Moreover, use of olfaction leads to an increased sense of reality and relevance. Our results also show that users are tolerant of the interference and distortion effects caused by olfactory effect in multimedia

Personalization in cultural heritage: the road travelled and the one ahead

Over the last 20 years, cultural heritage has been a favored domain for personalization research. For years, researchers have experimented with the cutting edge technology of the day; now, with the convergence of internet and wireless technology, and the increasing adoption of the Web as a platform for the publication of information, the visitor is able to exploit cultural heritage material before, during and after the visit, having different goals and requirements in each phase. However, cultural heritage sites have a huge amount of information to present, which must be filtered and personalized in order to enable the individual user to easily access it. Personalization of cultural heritage information requires a system that is able to model the user (e.g., interest, knowledge and other personal characteristics), as well as contextual aspects, select the most appropriate content, and deliver it in the most suitable way. It should be noted that achieving this result is extremely challenging in the case of first-time users, such as tourists who visit a cultural heritage site for the first time (and maybe the only time in their life). In addition, as tourism is a social activity, adapting to the individual is not enough because groups and communities have to be modeled and supported as well, taking into account their mutual interests, previous mutual experience, and requirements. How to model and represent the user(s) and the context of the visit and how to reason with regard to the information that is available are the challenges faced by researchers in personalization of cultural heritage. Notwithstanding the effort invested so far, a definite solution is far from being reached, mainly because new technology and new aspects of personalization are constantly being introduced. This article surveys the research in this area. Starting from the earlier systems, which presented cultural heritage information in kiosks, it summarizes the evolution of personalization techniques in museum web sites, virtual collections and mobile guides, until recent extension of cultural heritage toward the semantic and social web. The paper concludes with current challenges and points out areas where future research is needed

SMIL State: an architecture and implementation for adaptive time-based web applications

In this paper we examine adaptive time-based web applications (or presentations). These are interactive presentations where time dictates which parts of the application are presented (providing the major structuring paradigm), and that require interactivity and other dynamic adaptation. We investigate the current technologies available to create such presentations and their shortcomings, and suggest a mechanism for addressing these shortcomings. This mechanism, SMIL State, can be used to add user-defined state to declarative time-based languages such as SMIL or SVG animation, thereby enabling the author to create control flows that are difficult to realize within the temporal containment model of the host languages. In addition, SMIL State can be used as a bridging mechanism between languages, enabling easy integration of external components into the web application. Finally, SMIL State enables richer expressions for content control. This paper defines SMIL State in terms of an introductory example, followed by a detailed specification of the State model. Next, the implementation of this model is discussed. We conclude with a set of potential use cases, including dynamic content adaptation and delayed insertion of custom content such as advertisements. © 2009 Springer Science+Business Media, LLC

Enhancing Social Sharing of Videos: Fragment, Annotate, Enrich, and Share

Media consumption is an inherently social activity, serving to communicate ideas and emotions across both small- and large-scale communities. The migration of the media experience to personal computers retains social viewing, but typically only via a non-social, strictly personal interface. This paper presents an architecture and implementation for media content selection, content (re)organization, and content sharing within a user community that is heterogeneous in terms of both participants and devices. In addition, our application allows the user to enrich the content as a differentiated personalization activity targeted to his/her peer-group. We describe the goals, architecture and implementation of our system in this paper. In order to validate our results, we also present results from two user studies involving disjoint sets of test participants

A case study of campus‐based flexible learning using the World Wide Web and computer conferencing

This paper explores the use of the World Wide Web (WWW) integrated with computer conferencing as a teaching and learning tool. The aim of the study described was to evaluate the effectiveness of the use of online materials designed in a flexible learning format and integrated with a computer conference. It was hoped that this would create additional opportunity for group discourse between campus‐based students. The paper is divided in the following way: a discussion of the context to new developments in teaching and learning is followed by an introduction to the case study. Finally the findings of the case study are discussed with reference to research from the field of collaborative systems (Orlikowski, 1992; Grudin, 1994) as a framework for reflection. Some tentative conclusions are made for future work

Audio masking effect on inter-component skews in olfaction-enhanced multimedia presentations

Media-rich content plays a vital role in consumer applications today, as these applications try to find new and interesting ways to engage their users. Video, audio, and the more traditional forms of media content continue to dominate with respect to the use of media content to enhance the user experience. Tactile interactivity has also now become widely popular in modern computing applications, while our olfactory and gustatory senses continue to have a limited role. However, in recent times, there have been significant advancements regarding the use of olfactory media content (i.e., smell), and there are a variety of devices now available to enable its computer-controlled emission. This paper explores the impact of the audio stream on user perception of olfactory-enhanced video content in the presence of skews between the olfactory and video media. This research uses the results from two experimental studies of user-perceived quality of olfactory-enhanced multimedia, where audio was present and absent, respectively. Specifically, the paper shows that the user Quality of Experience (QoE) is generally higher in the absence of audio for nearly perfect synchronized olfactory-enhanced multimedia presentations (i.e., an olfactory media skew of between {−10,+10s}); however, for greater olfactory media skews (ranging between {−30s;−10s} and {+10s, +30s}) user QoE is higher when the audio stream is present. It can be concluded that the presence of the audio has the ability to mask larger synchronization skews between the other media components in olfaction-enhanced multimedia presentations
