A Smart Phone Tool to Create Photo Collages

AbstractThis paper presents the application PhotoPieces, a software tool which allows people to create photo collages on the fly in a camera-equipped handheld device using predefined or custom templates. Users can also create their own templates on-the- fly taking a photo and transforming it into a multi-region image template. A preliminary study with different types of users has been conducted to evaluate its value as a creative tool

Distributed multi-touch virtual collaborative environments

Abstract – We present a Remote Multi-touch Collaborative Environment that integrates videoconferencing in an immersive shared space. The proposed solution supports synchronous remote and co-located interactions of two or more users sharing the same virtual workspace. Two applications, that incorporate 2D and 3D shared space, have been developed. I

Proof-of-Concept Application - Annual Report Year 1

In this document the Cat-COVITE Application for use in the CATNETS Project is introduced and motivated. Furthermore an introduction to the catallactic middleware and Web Services Agreement (WS-Agreement) concepts is given as a basis for the future work. Requirements for the application of Cat-COVITE with in catallactic systems are analysed. Finally the integration of the Cat-COVITE application and the catallactic middleware is described. --Grid Computing

Proof-of-Concept Application - Annual Report Year 2

This document first gives an introduction to Application Layer Networks and subsequently presents the catallactic resource allocation model and its integration into the middleware architecture of the developed prototype. Furthermore use cases for employed service models in such scenarios are presented as general application scenarios as well as two very detailed cases: Query services and Data Mining services. This work concludes by describing the middleware implementation and evaluation as well as future work in this area. --Grid Computing

Performance Evaluation - Annual Report Year 2

In this paper a performance measuring infrastructure,developed for the prototype and simulator, concering the experiment configuration, data measurement, and data collection, is presented. A corresponding performance evaluation framework is defined to obtain the metrics from the measured data. Initial experiments were carried out to test the developed prototype, simulator and the performance measuring infrastructure. --Grid Computing

Application deployment using catallactic Grid middleware

In this paper we describe an application deployment using a Catallactic Grid-enabled middleware, which is based on the Catallaxy "free market" self-organisation approach described by von Hayek [7], who understood the market as a decentralised coordination mechanism opposite to a centralised command economy. The implementation makes use of Globus Toolkit, JXTA and WSRF. The paper envisages the resource virtualization in the WSRF context as the main driver for a proper connection middleware-base platform (on the broad scenario of grid applications)
