Narrative is an important component of modern digital games. As computer graphics have become more sophisticated and realistic, it has become increasingly necessary for game designers to develop new techniques to capture the attention of their audience. One such technique is the introduction of a narrative element as an integral part of the game experience [1]. The ability to effectively tell a...

We have previously developed Astrojumper, an exercise video game with a space theme that uses the Microsoft Kinect to support full-body exertion play. In this paper, we present the design and evaluation of Astrojumper-Intervals, a new version of our Astrojumper exergame, that explores methods of improving upon the previous game in both aspects of enjoyment and exercise effectiveness. We also in...

Equilibrium or near-equilibrium solutions to very large extensive form games are often computed by using abstractions to reduce the game size. A common abstraction technique for games with a large number of available actions is to restrict the number of legal actions in every state. This method has been used to discover equilibrium solutions for the game of no-limit heads-up Texas Hold’em. When...

The game-playing technique is a powerful tool for analyzing cryptographic constructions. We illustrate this by using games as the central tool for proving security of three-key tripleencryption, a long-standing open problem. Our result, which is in the ideal-cipher model, demonstrates that for DES parameters (56-bit keys and 64-bit plaintexts) an adversary’s maximal advantage is small until it ...

Procedural content generation is often seen simply as a means to generate ‘stuff ’, elaborating on or rearranging abstract data types that describe levels or modular pieces of gameplay. Generating content which is situated in an understanding of the real-world is a much harder task; it requires access to large amounts of knowledge, and a good technique for parsing and using that knowledge. In t...

It has been shown that the emotional state of students has an important relationship with learning; for instance, engaged concentration is positively correlated with learning. This paper proposes the Fuzzy Control for Improving Learning (FCIL), the proposed technique induces emotions in the player for supporting the learning process. The fuzzy system analyzes the players' emotional state for co...

This study intends to use data visualization to examine learners’ behaviors in a 3D immersive serious game for middle school science to understand how the players interact with various features to solve the central problem. The analysis combined game log data with measures of in-game performance and learners’ goal orientations. The fi ndings indicated students in the high performance and master...

Xbox-360 has three cores with six logical threads and the PlayStation-3 has one master core and six independent worker cores. According to the current design trends, multicore processors will be ubiquitous in every game computer. A game engine has many ‘components’ and multithreading is an important technique to parallelize the execution of these components. However, effective programming of mu...
