In this paper, we present a new model to analyse therapeutic games. The goal of the model is to describe and analyse the relations between the three aspects of a therapeutic game: the player, the game, and the therapy. The model is intended to game designers. It is a tool to improve the communication between health experts and game designers, and to(More)
In this this paper, we discuss the interest and the need to evaluate the difficulty of single player video games. We first show the importance of difficulty, drawing from semiotics to explain the link between tension-resolution cycles, and challenge with the player's enjoyment. Then, we report related work on automatic gameplay analysis. We show through a(More)
This paper is a first step toward the exploration and further development of the narrative possibilities offered by emergent games. First, we present the five characteristics of emergent narratives that we believe to be fundamental: coherence, agency, possibility space, uncertainty and co-authoring. Then, we investigate the presence of these characteristics(More)
This paper synthetically presents a reliable and generic way to evaluate the difficulty of video games, and an experiment testing its accuracy and concordance with subjective assessments of difficulty. We propose a way to split the gameplay into measurable items, and to take into account the player's apprenticeship to statistically evaluate the game's(More)
This paper describes the DEEP project (Dialogs taking into account Experience, Emotions and Personality, adapted to computer games), which started in June 2006. The aim of the project is to provide generic solutions for the integration of autonomous Non Player Characters (NPCs) in next-generation adventure games. DEEP NPCs, equipped with a personality and a(More)
In this paper, we present a collaborative game designed for Sifteo Cubes, a new tangible interface for multiplayer games. We discuss how this game exploits the platform's interface to transfer some of the game mechanics into the non-digital world, and how this approach affects both the player's experience and the design process. We present the technical(More)
Protein-protein interactions play a crucial role in biological processes. Protein docking calculations' goal is to predict, given two proteins of known structures, the associate conformation of the corresponding complex. Here, we present a new interactive protein docking system, Udock, that makes use of users' cognitive capabilities added up. In Udock, the(More)
In the present work, we describe and discuss two interactive visual-ization techniques recently added to the Udock software. First, we propose to display a spherical projection of the protein's molecular surface properties. The resulting 2D map allows to get in one glance a global view of the protein. Second, we propose to let the user choose a specific(More)
