Chopsticks API Allows Application Developers to Submit Raw Signed Transactions to All Post-2018-November-15-Fork BCH Chains

This paper is use case oriented. It focuses on RFID/NFC architectures and their main features to provide serious pervasive games in a museum context. It relates our experiments and results issued from the PLUG (Play Ubiquitous Games and play more) research project. Two mixed reality games have been provided. Each one is supported by its own middleware. The two middlewares and their main characteristics are presented. We underline in each case the advantages of using RFID/NFC technologies.

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… Show more

Ubiquitous computing architectures are an obvious choice for enabling interaction and collaboration in a multiuser application. We de- scribe important properties of such an architecture that are necessary to support the demands of mobility, communication, and general context- awareness, and discuss the challenges of applying these in a real-world, practical scenario of a multi-user game, ”SoundPark,” that operates over heterogeneous hardware and run-time environments. In addition, we note how… Show more

uGASP is an OSGi based middleware dedicated to ubiquitous multiplayer games. This middleware is built on top of the iPOJO service oriented component model. This demonstration enlightens the benefits of an OSGi / iPOJO approach to make a flexible, modular and configurable middleware. Moreover, it introduces our component model to provide ubiquitous gaming services to the hosted game server logics. Finally, it presents the first ubiquitous service for uGASP which enables to create multiplayer… Show more

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… Show more

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. Show less

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… Show more

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.
