Video games are typically executed on Windows platforms with DirectX API and require high performance CPUs and graphics hardware. For pervasive gaming in various environments like at home, hotels, or internet cafes, it is beneficial to run games also on mobile devices and modest performance CE devices avoiding the necessity of placing a noisy workstation in the living room or costly computers/consoles in each room of a hotel. This paper presents a new cross-platform approach for distributed 3D gaming in wired/wireless local networks. We introduce the novel system architecture and protocols used to transfer the game graphics data across the network to end devices. Simultaneous execution of video games on a central server and a novel streaming approach of the 3D graphics output to multiple end devices enable the access of games on low cost set top boxes and handheld devices that natively lack the power of executing a game with high-quality graphical output.

This paper presents a user-study of the TOTEM.Scout mobile tool that has been developed for in-situ creation of location-based content for games and edutainment applications based on configurable data templates. It works in cooperation with the TOTEM.Designer web-based tool and enables convenient structuring, management and export of the created content to prepare arbitrary location-based experiences. We motivate the necessity of this tool as well as its architecture, and describe the layout, results and findings of the performed case study in a real context of use. The results provide insights into possible improvements in terms of user interface and the tool's functionality design, and suggest new features for data collection and management

Abstract-In this paper we present a new cross-platform approach for video game delivery in wired and wireless local networks. The developed 3D streaming and video streaming approaches enable users to access video games on set top boxes and handheld devices that natively are not capable to run PC games. During the development of the distributed gaming system we have faced a number of challenges and problems posed by the hardware and network limitations. In order to solve these problems we have developed a multilevel testing methodology which is based on user assessment and technical measures for the system under development. In this paper we focus on the technical measures and instrumentation that we use for the system's performance measurement and testing. The benefits of our testing methodology are demonstrated through examples from the development and testing work.

Distributed gaming enables access to interactive media from devices based on different platforms. It facilitates users to enjoy video games in various environments without the need for using a single device or operating system. Understanding the potential and limitations of such gaming-on-demand systems is key for their adoption and further growth in public places. This paper presents an in-depth, quantitative study performed with the Games@Large (GaL) distributed-gaming system and its potential users at an Internet café in Genoa, Italy. The approach of the study was multilevel, covering the player experience and user acceptance aspects as well as technical performance peculiarities. Results show that the GaL system has a high potential at Internet cafes, in particular when playing a casual genre game. Furthermore, results provide recommendations for deploying such systems in terms of social setting and technical aspects. The methodology and findings of the GaL system tests can be applied to similar game streaming systems and used as input for theories on social digital game play.
