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......

A physically grounded approach to coordinate movements in a team
- Trang 373-378
Focuses on the problem of coordinating the movements of a cooperative team in an environment, and proposes an approach that takes inspiration from the laws of physics. The idea is to have the movements of team members driven by abstract force fields, generated by team members themselves and propagated via some embedded infrastructure. A globally coordinated and self-organized behavior in team memb......

Efficient distribution-based event filtering
- Trang 525-532
Event notification services are used in various applications, for example, stock tickers, environmental monitoring, and facility management. Several filtering algorithms for such services have been proposed. The best performance results are achieved by tree-based algorithms. However to our knowledge existing algorithms do not consider the influence of event and profile distribution on the filter p......

A collaborative infrastructure for scalable and robust news delivery
- Trang 655-659
In this paper we describe the model used for the NewsWire collaborative content delivery system. The system builds on the robustness and scalability of Astrolabe to weave a peer-to-peer infrastructure for real time delivery of news items. The goal of the system is to deliver news updates to hundreds of thousands of subscribers within tens of seconds of the moment of publishing. The system signific......

A service-based architecture for in-vehicle telematics systems
- Trang 741-742
The growing needs to access information in remote, mobile environments have sparked interests in so-called In-Vehicle Telematics Systems (IVTS). These relatively new systems have the potential to deliver computing facilitates to road vehicles, which may include in-vehicle infotainment, route-guidance and navigation and the provision of vital information resources used by fleet haulage companies an......

Assuring message delivery in mobile ad hoc networks with packet erasure recovery
- Trang 14-19
In addition to depending on wireless links-which are less reliable than wired ones-mobile ad hoc networks (MANET) introduce a unique set of operational characteristics that affect message delivery assurance. One such characteristic is that the mobility of nodes in a MANET causes the topology of the entire network to alter dynamically. In particular, as a change in a single link can alter the entir......

Progressive HTML for proximate and automatic interactions
- Trang 723-727
Development and projections in the field of PDAs and wireless communication architectures let us consider new applications which exploit short range and direct exchanges. In a close future we may imagine mobile users equipped with wireless PDAs dynamically and spontaneously exchanging rich information in an ad hoc manner In such a context, a connection between two PDAs may be broken at any time be......

Mobility of context for project teams
- Trang 391-395
In the last decade, bureaucratic organizational hierarchies increasingly have been replaced with flatter organizational forms, bringing together people from different disciplines to form project teams within and between organizations. Distributed project teams often are self-configuring networks of mobile and "fixed" people, devices, and applications. They are the natural next step in the evolutio......

An agent based matchmaking system using knowledge base
- Trang 142-146
With the spread of the Internet, the number of users and hosts has been increased exponentially. Also, newly emerging services try to provide users with more enhanced quality of service (QoS). The increase of users and hosts and the enhancement of QoS have caused a radical increase of Internet traffic. As a result, it is very difficult for users to find required information and the information loc......

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......
