With the rapid development of embedded system, distributed and mobile computing technologies, more and more intelligent space are establishing around us, such as smart meeting room, smart home, intelligent museum, digital library and so on. Meanwhile, ubiquitous computing has received an intensive interest in the past years. Many models have been proposed. How to utilize these models to enhance those intelligent spaces is a challenging research problem. We have introduced the prototype of rich servants service (RSS) model (Shi et al., 2007). In this paper, we will extend the RSS model to fulfill those intelligent spaces. The model defines elements, interfaces, agents, services discovery and other facts related to the system. Through a case, we show how to combine the RSS model with real-world applications.

This paper describes two algorithms for optimizing the design of distributed perimeter security systems. The first algorithm is a straightforward algorithm whose primary purpose is to help us formulate the problem formally. The second algorithm, is a genetic algorithm. Both algorithms were incorporated into a new module for our distributed security systems CAD software. Tests of the module show that it produced better solutions more quickly than any other algorithms that are known to us.

In an effort to develop a tool for automatic ontology building from Malay text based on formal concept analysis, an effective natural language processing (NLP) tool as the pre-processing components is needed. The goal of the study is to investigate whether existing Malay NLP tools can be a viable component to be part of the ontology learning tool. This paper discusses the outcome of the study on three NLP applications. The annotated corpus approach was adopted in this study as deemed suitable for exploratory research. Using the metrics relative subject recall and precision, the results obtained show that statistical modeling technique outperformed pola grammar technique.

This paper introduces techniques for the exploration of images augmented with additional information. We present the so-called meta-previewer and propose the cascading-views which are widgets that can assist the end-user in interactively exploring metadata embedded in augmented images. In this regard, the term Interactive Images (Sonnet et al., 2008) will refer to those augmented images which allow the end-user to request further information which is in relation to the entire image or parts of it. Using our tools, data exploration process is accomplished following three steps: (i) getting an overview of the image regions that contain additional information, (ii) requesting and displaying the additional information which is of interest, and (iii) diving into that additional information to get even more information linked with it.

In this paper, we describe a digital library initiative for non-textual documents. The proposed framework will integrate different types of content-repositories - each one specialized for a specific multimedia domain - into one seamless system and will add features such as automatic annotation, full-text retrieval and recommender services to non-textual documents. Two multimedia domains, 3D graphics and music, will be introduced. The repositories can be searched using both textual (metadata-based) and non-textual retrieval mechanisms (e.g. using a complex sketch-based interface for searching in 3D-models or a query-by-humming interface for music). Domain-specific metadata models are developed and workflows for automated content-based data analysis and indexing proposed.

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. Among the ancient Greeks, the techne, which included the sciences, were based in the arts. Our modes of knowledge production have since separated and grown alienated. "What weird stuff are those people doing?" To bridge the divide, we must understand and acknowledge differences, and use this as a basis for discovering common ground. In the sciences, knowledge is constructed empirically, through hypotheses and validations. Aesthetics and concepts play essential roles in how works of art are formulated to stimulate experiences. Where do these aims intersect and how might they inform each other? In this conference, one track develops pattern recognition methods for content analysis and retrieval. Another develops network and system techniques. Applications invoke these methods in usable systems. Human-centered multimedia serves as a bridge connecting human experiences with algorithmic methods. The interactive art program develops new concepts of how multimedia can function culturally, amidst society,

We present a method to produce smooth transitions between arbitrary pieces of character animation, which is based on the application of dynamic transition curves. Unlike other approaches, we achieve anytime interruptibility for body expressions, that is, gestures can be changed anytime during execution while maintaining naturalness of motion transition. To obtain highly natural skeletal movement, our approach is integrated with motion parametrization, as proposed in the\Verbs and Adverbs" technique [18], and further methods of fuzzy motion blending. We will demonstrate how the latest version of the Multimodal Presentation Markup Language (MPML3D) integrates parameterized agent behavior, and can support the incorporation of personality and emotional attentiveness in a straightforward way.

Delay-tolerant networking (DTN) is an architecture to enable data communications between isolated or remote regions, where long delays and intermittent connectivity can be tolerated. An emerging class of DTN, called vehicular DTNs (VDTN), exploits transportation systems as the transport layer to transfer data. In these networks, vehicles (e.g., busses, boats, trains) act as mobile nodes and carry data messages around. Mobile nodes can exchange data messages using devices called relay nodes. Relay nodes, placed in strategic positions along vehicle routes, have the capability to download, store, and upload the data messages from/to the mobile nodes. An important issue in VDTN is the optimal placement of the relay nodes such that delay-tolerant connectivity in VDTN is ensured at minimum cost. In this paper we show that the problem of optimal relay node placement is an NP-hard problem. Other contributions of this paper are the formulation of the relay node placement problem using ILP and the proposal of heuristic algorithms solving the optimization problem. Using simulation results, we compare the performance of each algorithm under different network constraints, such as node storage capability and network topology.
