A game on a convex geometry was introduced by Bilbao as a model of partial cooperation. We investigate some properties of the core of a game on a convex geometry. First, we show that if a game is quasi-convex, then the core is stable. This result can be seen as an extension of a result by Shapley for traditional cooperative games. Secondly, we show the core on the class of balanced games on a c...

Since the late 1990s researchers started to investigate augmented tabletop games that are closing the gap between traditional board games and video games. With this development the necessity to evaluate these tabletop games increases. We identified ten heuristics, all of which have been evaluated with experts playing with four different tabletop games. Our heuristics contain all facets offered ...

This study examined the effects of using serious games for training on task performance and declarative knowledge outcomes. The purpose was to determine if serious games are more effective training tools than traditional methods. Self-efficacy, expectations for training, and engagement were considered as moderators of the relationship between type of training and task performance as well as typ...

Critics of games’ narrative ability fail to recognize that narrative impact in games is established differently than in traditional media. This paper demonstrates how agency and avatar relationships affect game narratives. Understanding these relationships may lead to improved understanding of the medium’s limitations or allow games to take on new types of narratives.

Destructable environments and objects in computer games make it difficult to use traditional game AI techniques for computer controlled agents. This paper presents a method to control the velocity of destructable flying objects with the help of system identification and model-based action extraction. A training scheme is developed that makes it possible to identify all parameters in isolation u...

Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...

besides being a recreational amusement, it also serves as an important function for the psychological, physiological and social development of a child. Children learn about themselves and the world and people around them; they develop and improve manifold and important skills, such as social competence, problem-solving and creativity. In contrast to traditional games, computer and video games t...

background: the rapid growth of computer games, has taken a major part of teenagers leisure time. the improper and overuse of these games, can be considered as physical, mental and social threats. the goal of this study was to determine the relationship between playing computer games and students’ aggression and academic progress.   methods: in this cross- sectional study, 292 students in grade...
