Abstract Scripting is used extensively in game development for the implementation of AI based behaviors. Game scripting languages have not, as yet, benefited from the move to multicore architectures. We propose a synchronous model of concurrency particular to game AI scripting that allows game scripting languages to fully utilize multicore processors. The next steps in developing this model further are discussed.... Scripting is used extensively in game development for the implementation of AI based behaviors.

Abstract This paper presents a new approach to model crowd behaviour in normal and risky situations. Our model is based on human cognitive characteristics specially personality type, perception and emotion that we assume relevant to individuals’ behavioural decisions. The model supports an efficient interaction between the different architecture components to provide behaviour. A formal definition of cognitive characteristics will be given... This paper presents a new approach to model crowd behaviour in normal and risky situations. Our model is based on human cognitive characteristics specially personality type, perception and emotion that we assume relevant to individuals’ behavioural decisions. The model supports an efficient interaction between the different architecture components to provide behaviour. A formal definition of cognitive characteristics will be given with a description of its use on the model.We demonstrate in this paper the ability of our model to provide emergent behaviour simulating realistic reactions within a crowd based on each individual’s attributes and environmental changes.

Abstract This work presents the current development of a Goal- Oriented Action Planning Architecture to be used in the DVRMedia2 Framework AI Engine. The purpose of this research is to model complex behaviours to be used for massive simulations, with thousands of virtual characters acting in a congruent manner in emergency situations, where first responders and civilian popula- tion could be...

The purpose of this research is to model complex behaviours to be used for massive simulations, with thousands of virtual characters acting in a congruent manner in emergency situations, where first responders and civilian popula- tion could be senzibilized and trained.

Abstract People experience emotions when playing videogames. It can be argued that these emotions are their main reason for playing. In this paper, we investigate whether colors can be used in videogames to elicit specific emotions.

People experience emotions when playing videogames. It can be argued that these emotions are their main reason for playing. In this paper, we investigate whether colors can be used in videogames to elicit specific emotions. We ran an experiment with a videogame in which four different colors, associated with four specific emotions, were used in four different conditions (in this case, four different rooms in the game). After each condition we measured the players’ emotional responses by means of a Self-Assessment Manikin (SAM) questionnaire. Our analysis revealed that the color red evoked a highly-aroused, negative emotional response, while the color yellow evoked a positive emotional response. These results were significantly different from the emotional responses measured for other colors. Furthermore, we found that inexperienced players showed much more explicit reactions to colors than experienced players. We conclude that the use of colors is a suitable method for game designers to elicit specific emotional responses from the players, in particular from novice players. Read More Read Less
