The MooDS protocol: a J2ME object-oriented communication protocol

This paper describes MooDS, an object-oriented communication protocol dedicated to Java 2 Micro Edition (J2ME) based mobile phones. This protocol is used in GASP, an open source middleware enabling J2ME multiplayer gaming interactions. This paper enlightens the difficulty in developing mutiplayer games in heavily constrained environments, like the J2ME CLDC platform: small application memory footprint, lack of object serialization support, network protocol limitations, small bandwith and lack of client IP addressing support within cellular phone networks. This paper details how MooDS takes care of these constraints by providing an efficient object serialization protocol in order to reduce the amount of transmitted data and to increase the communication speed. Moreover, MooDS is compared with the available J2ME SOAP based protocol implementations, kSOAP2 and JSR172. This paper shows that MooDS obtains the best results in terms of encoding length, transmission delay, memory allocation and application code size, thus supplying a proper gaming interaction support, in particular for time critical multiplayer games.

When RFIDs meet artist's painting

This work challenges to create paintings augmented with RFIDs.

Exploring contemporary painting through spatial annotations using RFID tags

One of the least explored RFID application-domains concerns the areas of entertainment and culture. This paper proposes a mobile application -conceived for and with a contemporary artist- allowing the spatial annotation of paintings and the delivery of multimedia related interpretation material to the concerned public, through the combined use of RFID tags and NFC (Near Field Communication) mobile phones, serving as delivery platforms. The paper reports on the design and implementation of the application as well as on the results of a first, proof-of-concept, evaluation.

Player profile management on NFC smart card for multiplayer ubiquitous games

One of the goals of mixed reality and ubiquitous computing technologies is to provide an adaptable and personal content at any moment, anywhere, and in any context. In Multiplayer Ubiquitous Games (MUGs), players have to interact in the real world at both physical and virtual levels. Player profiles in MUGs offer an opportunity to provide personalized services to gamers. This paper presents a way to manage MUG player profiles on an NFC Smart Card, and proposes a Java API to integrate Smart Cards in the development of MUGs. This user centric approach brings new forms of gameplay, allowing the player to interact with the game or with other players any time and anywhere. Smart Cards should also help improve the security, ubiquity, and the user mobility in traditional MUGs.

RFID Painting Demonstration

This demonstration challenges the conventional art experience. It brings together the fields of art, science, and software integration. The goal was to create a new kind of painting based on embedded technology, experimenting with a new media: paintings augmented with RFIDs. The aim was to achieve interaction between the artists paintings and art gallery visitors.

Vers une intégration du RFID et de la cartographie pour une visite autonome du musée des arts et métiers

We describe current works related to technological building blocks able to help people visiting museums. We present the use of RFID tags through a mobile phone and web enabled indoor maps. The paper concludes with future works.
