In this paper, we propose a method for image selection using Web image search for automatic video biography authoring. In the proposed method, images are selected from the image search results considering their visual contents for inclusion in the video biography. Through evaluation, we confirmed the effectiveness of the proposed image selection method compared to a baseline method which simply selects the top 1 search result.

Since the Like-button was introduced in 2009 by Facebook, its use increased rapidly. Liking became an important part of our daily routines on the internet since we are able to like almost any creative expression, such as photos and videos. Little is known about the effects of liking (and disliking) on these creative expressions. This paper investigates how the (dis)liking feature influences creativity. We conducted an experiment with a photo-application for mobile phones and provided different combinations of liking and disliking to two research groups and a control group. Our findings suggest that providing a liking feature is beneficial to creativity in terms of the production of creative content and results in higher amounts of photos. Providing a disliking feature as well is beneficial to creativity in terms of quality and results in higher rates for the photos.

Art can reflect in depth about data (vertical) and at the same time has an aesthetical, ontological, intentional, and conscious realm (horizontal) that can communicate cross-dimensionally to the general public. In that way data can be contextualized in its being, can be made palpable and hence facilitate the communication of data into communication about data. The art exhibition of the 24th ACM MM conference will be presented at the Amsterdam Public Library (http://www.oba.nl/oba/english.html) and aims to provide art works that critically reflect on the use of data in procedural contexts. The presented art works were established in collaborations between artists and researchers that, in cases, have access to large data volumes. The presented art works make use of non-motivated and motivated functions art is valued for, as it is art in its act of resembling, expression and the presentation of the self that facilitates the representation of reality.

The study used a research-through-design approach and organized game jams as a method to examine game design processes, with the aim to investigate how the diverse identities of designers affect and inspire their game designs. During the Game [4Diversity] Jams we hypothesised that homogeneity in groups may lead to a single-minded message in their games, and diversity in groups may result in games that allow more freedom for players to create their own personal interpretation(s) of the game's content and mechanics. The results of this study suggest that a narrow theme and diverse team composition may assist designers in creating novel games. As such, designers can find diverse gameplay and content from additional specificity in the game jam's organisation.

This paper presents the motivation, design and evaluation of CountMeIn, a mobile collaborative pervasive memory game to revive social interactions in public places (e.g. a train station or bus stop). Two versions of CountMeIn were tested; an NFC-based and a touchscreen version. In a 2×1 within-subject (NFC vs. Touch) experiment (N = 20), postexperiment group interviews and findings indicate the NFC version led to increased perception of social presence while participants were more aware of others' actions and intentions (mode of co-presence). However, we did not find quantitative evidence that attributes of social presence were higher from the Social Presence Game Questionnaire. Together, our findings suggest that placement of a physical NFC interface does not necessarily increase perceived social presence when users play collaboratively. However, social expansion in mobile collaborative pervasive games can greatly benefit from people's mutual awareness from such an interface. This mutual awareness has the potential to both attract users and spectators, and reduce anxiety of users to invite spectators, or accept an invite from users.

Computer-supported group formation enables educators to assign students to project teams.The focus in this paper is placed on gathering data about student attributes that are relevant in the context of specific course projects.We developed a method that automatically produces learner models from existing documents, by linking students to topics and estimating the levels of skill, knowledge, and interest that students have in these topics.The method is evaluated in an experiment with student participants, wherein its performance is measured on two levels.Our results demonstrate that it is possible to link students to topics with high precision, but suggest that estimating mastery levels is a more challenging task.

Urban mobility analysis of geotagged photos can unlock mobility patterns of users who took these photos, which can be used for exploration-based city route planners. Applying sequence alignment techniques on 5 years of geotagged Flickr photos in Amsterdam (The Netherlands) allowed creating walkable city routes based on paths traversed by multiple photographers (or photographer paths). To evaluate our approach, we conducted a user study with Amsterdam residents to compare our routes with the most efficient and popular route variations. Drawing on experience questionnaire data, web survey responses, and user interviews, our results show that our photographer paths were perceived as most stimulating and suitable for city exploration. Moreover, while digital aids based on photographer paths can potentially aid city exploration, their acceptance in mainstream route planners likely depends on their visualization. From our proof-of-concept approach and user study findings, we discuss the potential of data-driven exploration-based city route planners.

Aggregated search interfaces provide users with an overview of results from various sources. Two general types of display exist: tabbed, with access to each source in a separate tab, and blended, which combines multiple sources into a single result page. Multi-session search tasks, e.g., a research project, consist of multiple stages, each with its own sub-tasks. Several factors involved in multi-session search tasks have been found to influence user search behavior. We investigate whether user preference for source presentation changes during a multi-session search task.

This paper describes a field study evaluating a mobile map application for the Paris Air Show. The aim of the study was to investigate how well users can navigate (to static and moving targets) and orient themselves in a fair (an unknown environment posing realistic challenges for wayfinding) with a mobile map system. The study involved 14 fair visitors who carried out three navigation tasks, which required them to switch between map navigation and deciding upon their orientation in the physical environment. Our results indicate that navigation and orientation are not as tightly coupled as described in the traditional wayfinding literature and may require different modality approaches to optimally support users. Based on this, we draw design implications on how to balance supporting the user in navigation and orientation with mobile systems without diminishing users' awareness of their surroundings.

Media studies concerns the study of production, content, and/or reception of various types of media. Today's continuous production and storage of media is changing the way media studies researchers work and requires the development of new search models and tools.

In this paper we present first results of an observation study on indoor navigation behaviour of visitors at a large public fair. As an outcome we present a number of requirements for mobile indoor navigation systems that support collaborative destination and path finding tasks.

One of the common parts of news is to provide the background for a current event, such as the resignation of a Prime Minister. This paper addresses a framework that facilitates semi-automated authoring of explanatory audio-visual news topics in a retrospective style for the domain of politics based on already edited new stories available in the repository of the news corporation. The aim is to facilitate a journalist with an audio-visual body based on which he/she can finalize the explanatory piece. The proposed framework enhances current state of the art video summarization by allowing the combination of different news stories into one coherent explanation about a topic of the current news. The framework introduces techniques that exploit demoscopic data in form of polls for the development of the general story outline; the automatic retrieval of relevant material by using a combination of event templates and automatic news summarization over topic threads; and the generation of the final video by applying a set of trimming rules. Example generations are presented and discussed and an outline of future work is presented.

In this paper we outline the aims and organization of the ACM MM 10 workshop on 'Interactive Multimedia Computing for Creativity and Expression'.

Stories are one of the primary forms we use to organize our lived experiences into patterned narratives that aspire to communicate that which is memorable and valuable. SRMC 2008 provides a forum for multimedia researchers and practitioners to share their novel insights and understandings of the human and machine storytelling abilities necessary for the development of engaging, participatory and sustainable multimedia systems.

Historically, the ACM Multimedia Conference is split into a "technical" program and an "arts" program. These programs sometimes seem completely separate from one another, victims of a "semantic gap" between disciplines. The goal of this panel is to create a space in which scientists learn from artists, and arts from science. We need to discover new connections between modalities of research. In order to create the most exciting and powerful future forms of interactive multimedia systems, the ones that will create the most beneficial broader impact on humanity, we need to foster new collaborations between artists and scientists. This panel seeks to bridge the great divide of language and communities that has fragmented us, creating a new space for developing connections between the arts and sciences of multimedia research, as embodied through the artists and scientists of ACM Multimedia. The goal is to make this conference a premier site for catalyzing emergent connections.

Blogs, wikis, tagging, podcasts, and social networking websites such as MySpace, Facebook, Flickr and YouTube have radically changed user interactions on the World Wide Web from a static, one-way, consumption model to a dynamic, multi-way, participation model. Broad user power and flexibility have changed how people engage in and experience their interconnections, interests, and collaborations. Online social interactions will evolve in the next decade to address the growing needs of its user community and make entries into many aspects of our lives. This evolution may very well be among the most exciting ones of our times where the individual and collective power of people to contribute and share content, experiences, ideas, expertise etc. may be even more enhanced than it is today. The enhancement may be shaped through a better understanding of user needs and behavior and it may be enabled through the seamless convergence of multi-modal technologies, new applications, new domains, data mining and better navigational and search capabilities. Some of these changes will also permeate into the workplace and change the way we work. This panel will discuss how online social interactions may evolve in the next decade and what impact it may have on diverse dimensions in our world.

The move.me prototype illustrates a scenario for social interaction in which users can manipulate audio-visual sources presented on various screens through an interaction with a sensor-enhanced pillow. The technology developed for move.me uses the surface of a pillow as a tactile interface. We describe the underlying concepts of move.me and its motivations. We present a case study of the environment as the context of evaluating aspects of our approach and conclude with plans for future work.

This paper describes the move.me interaction prototype developed in conjunction with V2_lab in Rotterdam. move.me proposes a scenario for social interaction and the notion of social intimacy. Interaction with sensory--enhanced, soft, pliable, tactile, throw-able cushions afford new approaches to pleasure, movement and play. A somatics approach to touch and kinaesthesia provides an underlying design framework. The technology developed for move.me uses the surface of the cushion as an intelligent tactile interface. Making use of a movement analysis system called Laban Effort-Shape, we have developed a model that provides a high-level interpretation of varying qualities of touch and motion trajectory. We describe the notion of social intimacy, and how we model it through techniques in somatics and performance practice. We describe the underlying concepts of move.me and its motivations. We illustrate the structural layers of interaction and related technical detail. Finally, we discuss the related body of work in the context of evaluating our approach and conclude with plans for future work.

We use rhetorical annotations to specify a generation process that can assemble meaningful video sequences with a communicative goal and an argumentative progression. Our annotation schema encodes the verbal information contained in the audio channel, identifying the claims the interviewees make and the argumentation structures they use to make those claims. Based on this schema, we construct a semantic graph which is traversed by rhetoric-based strategies selecting video segments. The selected video segments are edited to form a meaningful video sequence.

Multimedia authoring is a complex, resource demanding, knowledge-intensive, and multilayered process. While a large part of presentation creation cases involve manual production of presentations, such as performed in daily work of students and teachers, most applications for manual production (e.g. PowerPoint, Director) are only working environments with no help on the conceptual level. We propose a framework for the authoring system called SampLe (semiautomatic presentation generation environment), where the system support is provided at any stage of the presentation building process. The support is managed by incorporating explicit knowledge about the domain, narrative structures, media modalities, and tasks involved into the process of multimedia presentation creation.

Multimedia presentation generation has to be able to balance the functional aspects of a presentation that address the information needs of the user and its aesthetic form. We demonstrate our approach using automatic colour design for which we integrate relevant aspects of colour theory. We do not provide a definition of the relative importance of form versus function, but seek to explore the roles of subjective elements in the generation process.

This paper considers the automated and semi-automated annotation of audiovisual media in a new type of production framework, A4SM (Authoring System for Syntactic, Semantic and Semiotic Modelling). We present the architecture of the framework and outline the underlying XML-Schema based content description structures of A4SM. We then describe tools for a news and demonstrate how video material can be annotated in real time and how this information can not only be used for retrieval but also can be used during the different phases of the production process itself. Finally, we discuss the pros and cons of our approach of evolving semantic networks as the basis for audio- visual content description.
