Latency and player actions in online games
The growth and penetration of broadband access networks to the home has fueled the growth of online games played over the Internet. As we write this article, it is 5am on a typical weekday morning and Gamespy Arcade 1 reports more than 250,000 players online playing about 75,000 games! This proliferation of online games has been matched by an equivalent growth in both th
Virtual Reality Games for Motor Rehabilitation
This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion
A Reusable Component for Communication and Data Synchronization in Mobile Distributed Interactive Applications
In Distributed Interactive Applications (DIA) such as multiplayer games,
where many participants are involved in a same game session and communicate
through a network, they may have an inconsistent view of the virtual world
because of the communication delays across the network. This issue becomes even
more challenging when communicating through a cellular network while executing
the DIA client on a mobile terminal. Consistency maintenance algorithms may be
used to obtain a uniform view of the virtual world. These algorithms are very
complex and hard to program and therefore, the implementation and the future
evolution of the application logic code become difficult. To solve this
problem, we propose an approach where the consistency concerns are handled
separately by a distributed component called a Synchronization Medium, which is
responsible for the communication management as well as the consistency
maintenance. We present the detailed architecture of the Synchronization Medium
and the generic interfaces it offers to DIAs. We evaluate our approach both
qualitatively and quantitatively. We first demonstrate that the Synchronization
Medium is a reusable component through the development of two game
applications, a car racing game and a space war game. A performance evaluation
then shows that the overhead introduced by the Synchronization Medium remains
acceptable.Comment: In Proceedings WCSI 2010, arXiv:1010.233
