Users often become frustrated when they are unable to understand and control a pervasive computing environment. Previous studies have shown that allowing users to pose why and why not questions about context-aware applications resulted in better understanding and stronger feelings of trust. Although why and why not questions have been used before to aid in debugging and to clarify graphical user interfaces,...
This paper presents a computer vision system that analyzes a scene, recognizes human behavior, and produces a semantic interpretation of the recognized behavior. Scene analysis consists of detecting motion and tracking detected objects. Then, the system detects events that define the current behavior of a person. Once behaviors are classified the system recognizes various predefined scenarios. Finally...
We propose a new method to analyze light transport in homogeneous scattering media. The incident light undergoes multiple bounces in translucent objects, and produces a complex light field. Our method analyzes the light transport in two steps. First, single and multiple scattering are separated by projecting high-frequency stripe patterns. Then, multiple scattering is decomposed into each bounce component...
In this paper we describe a system for creating a navigable mirror world, utilizing community photographs of real life environments. We present the essential architecture and a prototype solution for not only geotagging, but also spatially structuring content. Mash-up interfaces are available towards 3rd parties, for linking and georeferencing their content.
We present a prototype mobile augmented reality client addition to the ??Image Space?? mixed reality media sharing service. We have explored how the real world aligned "mirror world" content from that service can be interacted with in-situ and identified two different use scenarios - geospatial media sharing and social connection. Since both the existing web based mirror world modality and...
The paper proposes an architecture of SIP-based network video surveillance system. Call mechanism of SIP gives a solution to the interconnection among multi-surveillance systems under complex networks. H.264 is adopted as encoding/decoding technology which has the higher compression rate than other technologies. The process of design and implementation are described and some key technologies are discussed...
Assault and robbery on the public transport is a social problem. Almost every day, people lose possessions and, in some cases, thieves or citizens get hurt or even die, in the process. In Mexico, attempts to reduce or prevent crime include vigilance by armed agents [1] and video cameras on public transport [2]. This work contributes to crime reduction and/or prevention on public transport by taking...
Leveraging large collections of georeferenced, community-contributed photographs can help solve three knowledge-discovery problems: annotating novel images, annotating geographic locations, and performing geographic discovery.
We propose a system for collecting and connecting people's stories. In order to help encourage participants to engage their ??expression mode,?? we employed mobile phones for video capture, as opposed to traditional video cameras. As part of our work, we held a workshop in an art festival. In the workshop, facilitators capture participants' stories using mobile phones. Applying a question-and-answer...
The IP Multimedia Subsystem (IMS) is being widely adopted as the standard service delivery architecture for Next Generation Networks. The IMS delivers rich IP-based multimedia services to end users. In order to fully utilize the potential of the IMS, the convergence of the World Wide Web and IMS capabilities is imperative. Services composed of Web 2.0 technologies and IMS based call control and multimedia...
The development and expansion of broadband technologies has stimulated the multimedia streaming market for the delivery of live streaming services which can be used for a variety of applications. The design of a generic audio and video streaming platform that can be employed for a wide range of applications is presented in this paper. A key feature of the platform is the `subscription framework' which...
Homelog is a continuous collection of digital records of various entities (including family members) about their existence states and activity experiences occurring in a home from the past to the present. The homelog can be regarded as a special home-oriented database whose data is captured automatically via various ubiquitous devices such as cameras, microphones, sensors, RFID tags, etc., which are...
This paper aims at responding to the questions in the traditional cultural heritage protection and exploring new visual representation forms and human-computer natural interaction design methods to carry forward the digital cultural heritage(DCH) projects. This paper combined interaction design with Chinese traditional shadow puppet art to create a new media artwork based on computer image capturing...
We are interested how to contextualize the digital content of an individual user with the help of content from other users, how to create a positive user experience from that, and what kind of interaction that can encourage between users. As a result the environment can be modelled. Creating a digital representation of the world from photographs is an exciting opportunity, for e.g. as a registering...
Rapidly evolving and widely-used smart phones provide many novel applications and services, making it possible to gather information from any location. Recent advances in technology have introduced many useful functions to assist users of outdoor mobile devices by sensing nearby conditions, such as the user's current location and even the user's slightest motions. Among these growing capabilities...
In the mixed reality of the computer installation Presence, which functions as a prototype for a smart space, the visitor is placed in the position of a person in audience with the king. The interaction with a digital avatar is structured according to the rules of social behaviours and following the script of the Shakespeare's play. The paper explains different aspects of the conceptualisation of...
Presently many posters, pamphlets, magazines, and company brochures have Internet URLs printed on them. Details that cannot be printed on paper such as the latest information or information about related services are published on the Internet. However there are various problems. Inputting a URL while looking at the printed material is troublesome, input mistakes can happen, and even if there are multiple...
This paper introduces and discusses a recent standardization project by the MPEG group that aims at providing an interoperable file format tailored to the needs of the surveillance industry. The new standard is called Video Surveillance Application Format and extends the H.264 - AVC file format specification. Based on a review of the application requirements, the rationale is provided for the technical...
This paper explores art, Artificial Life and the creation of new modes of realism. A brief survey charting significant Artificial Life artworks using aesthetic selection contextualizes the current status of realism in Artificial Life. Drawing on dasiamedia ecologypsila the paper examines the relationship between realism, codes of representation and what we see as real and dasiatrue to lifepsila. These...
