The eSleeve: a novel wearable computer configuration for the discovery of situated information
- Trang 793-796
Describes work in progress on wearable computing configurations which provide audio and visual output based on the position and orientation of the user. We introduce the 'eSleeve'-a wearable wrist computer with position and heading sensors combined with a user interface employing speech recognition and a small display. Applications described include searching a database of locations, and implement......

The numeric indexing for music data
- Trang 258-263
The management of large collections of music data in a multimedia database has received much attention in the past few years. In most current work, researchers extract features from the music data and develop indices that will help to retrieve the relevant music quickly. Several reports have pointed out that these features of music can be transformed and represented in the form of music feature st......

A multi-user interactive 3D presentation system via the Internet
- Trang 279-284
The popularity of the Internet has opened up many ways to distribute information to a desired audience. The information usually comes in the way of web sites, chat rooms, newsgroups, etc. Although the above methods of presenting information are invaluable, technology has come to the stage in which a more robust method of presenting information can be widely distributed. This paper presents a new m......

Implementing a distributed lecture-on-demand multimedia presentation system
- Trang 111-115
Lecture-on-demand (LOD) multimedia presentation technologies in networks are most often used in communication services. Examples of those applications include video-on demand, interactive TV and communication tools in a distance learning system, etc. In this paper, we describe how to present different multimedia objects on a Web-based presentation system. The distributed approach is based on an ex......

Toward a peer-to-peer shared virtual reality
- Trang 695-700
This paper envisions a shared virtual reality system that could handle millions of users and objects. The SOLIPSIS system does not rely on servers and is based on a network of peers that collaborate to build up a common virtual world. Real-time interactions and virtual co-presence are enabled by the means of emissive and receptive fields that determine how avatar kinestesia and multimedia streams ......

Exploiting logical mobility in mobile computing middleware
- Trang 385-386
We consider the following forms of mobile interactions: client/server interactions, whereby the request of a client triggers the execution of a unit of code in a server and returns the results to the client; remote evaluation, where a device can send code to another host, have it executed and retrieve the result; code on demand, where a host can request a unit of code from another device to be ret......

Subscription summaries for scalability and efficiency in publish/subscribe systems
- Trang 619-624
A key issue when designing and implementing largescale publish/subscribe systems is how to efficiently propagate subscriptions among the brokers of the system. Brokers require this information in order to forward incoming events only to interested users, filtering out unrelated events, which can save significant overheads (particularly network bandwidth and processing time at the brokers). In this......

An adaptive run time manager for the dynamic integration and interaction resolution of features
- Trang 445-450
With modern software systems, an important requirement is the ability to be auto adaptive, i.e. being able to adjust itself its changing environment. In line with this, a run time manager for dynamic feature integration of telecommunication systems, interaction detection and resolution is described in this paper with aspects being used to implement features. The manager manages the interaction of ......

An event-driven system for distributed multimedia applications
- Trang 583-584
We propose an architecture for distributed multimedia applications based on an event-driven programming model. To avoid the synchronization problems inherent to multi-threaded programming, the proposed architecture is based on a single-threaded structure. Instead of multi-threading, we opted for the event-oriented approach allied to multiple communication channels with user-defined handling proced......

PFTPD: an FTP proxy system to assure the freshness of files
- Trang 57-62
As more software is being developed and distributed via the Internet, the number of accesses to file servers, such as FTP servers or WWW servers, is increasing. To reduce concentrated access to the original file server, mirror servers which have the same directories and files as the original server stores have been introduced. However, inconsistency among mirror servers and the original server is ......
