Agents, Believability and Embodiment in Advanced Learning Environments

On the World Wide Web we see a growing number of general HCI interfaces, interfaces to educational or entertainment systems, interfaces to professional environments, etc., where an animated face, a cartoon character or a human-like virtual agent has the task to assist the user, to engage the user into a conversation or to educate the user. What can be said say about the effects a human-like agent has on a student's performance? We discuss agents, their intelligence, embodiment and interaction modalities. In particular, we introduce viewpoints and questions about roles embodied agents can play in educational environment

Recognizing complex gestures via natural interfaces

Natural interfaces have revolutionized the way we interact with computers. They have provided in many fields a comfortable and efficient mechanism that requires no computer knowledge, nor artificial controlling devices, but allow as to interoperate via natural gestures. Diverse fields such as entertainment, remote control, medicine, fitness exercise are finding improvements with the introduction of this technology. However, most of these sensorial interfaces only provide support for basic gestures. In this work we show how it is possible to construct your own complex gestures using the underlying capabilities of these sensor devices.Universidad de Málaga.

Human factors in entertainment computing: designing for diversity

Although several casual gaming systems have been developed during the past years, little research examining the impact of human factors on the design and use of digital games has been carried out, and commercially available games are only partially suitable for audiences with special needs. The research project described within this paper aims to analyze and explore design guidelines for diverse audiences and results of focus group gaming sessions to develop a research toolbox allowing for the easy creation of adaptable and accessible game scenarios. Thereby, a controllable environment for the detailed evaluation of the interrelations between human factors and entertainment systems is provided. Results obtained by further testing will be integrated in the toolbox, and may foster the development of accessible games, thus opening up new opportunities for diverse audiences and allowing them to further engage in digital games.

Observations on Experience and Flow in Movement-Based Interaction

Movement-based interfaces assume that their users move. Users have to perform exercises, they have to dance, they have to golf or football, or they want to train particular bodily skills. Many examples of those interfaces exist, sometimes asking for subtle interaction between user and interface and sometimes asking for ‘brute force’ interaction between user and interface. Often these interfaces mediate between players of a game. Obviously, one of the players may be a virtual human. We embed this interface research in ambient intelligence and entertainment computing research, and the interfaces we consider are not only mediating, but they also ‘add’ intelligence to the interaction. Intelligent movement-based interfaces, being able to know and learn about their users, should also be able to provide means to keep their users engaged in the interaction. Issues that will be discussed in this chapter are ‘flow’ and ‘immersion’ for movement-based interfaces and we look at the possible role of interaction synchrony to measure and support engagement

Preface

These are the proceedings of the 3rd International Conference on Intelligent Technologies for Interactive Entertainment (INTETAIN 09). The first edition of this conference, organised in Madonna di Campiglio, saw the gathering of a diverse audience with broad and varied interests. With presentations on topics ranging from underlying technology to intelligent interaction and entertainment applications, several inspiring invited lectures, a demonstration session and a hands-on design garage, that first edition of INTETAIN generated a lot of interaction between participants in a lively atmosphere. We hope that we have managed to continue this direction with the third edition, which will take place in Amsterdam, following the second edition held in Cancun. The submissions for short and long papers this year show a certain focus on topics such as emergent games, exertion interfaces and embodied interaction, but also cover important topics of the previous editions, such as, affective user interfaces, story telling, sensors, tele-presence in entertainment, animation, edutainment, and (interactive) art. The presentation of the accepted papers, together with the many interactive demonstrations of entertainment and art installations, and other participative activities to be held during the conference, should go some way towards recreating the open and interactive atmosphere that has been the goal of INTETAIN since its beginning. In addition to the aforementioned papers and demonstrations, we are happy to present contributions from three excellent invited speakers for INTETAIN 09. Matthias Rauterberg of Eindhoven University, in his contribution titled “Entertainment Computing, Social Transformation and the Quantum Field��?, takes a broad view as he discusses positive aspects of entertainment computing regarding its capacity for social transformation. Michael Mateas, of the University of California, Santa Cruz, talks about his work in interactive art and storytelling. Antonio Camurri, of InfoMus Lab, Genova, discusses an approach to Human Music Interaction that assigns a more active role to users listening to and interacting with music, in his contribution titled “Non-verbal full body emotional and social interaction: a case study on multimedia systems for active music listening��?

Handling Data-Based Concurrency in Context-Aware Service Protocols

Dependency analysis is a technique to identify and determine data dependencies between service protocols. Protocols evolving concurrently in the service composition need to impose an order in their execution if there exist data dependencies. In this work, we describe a model to formalise context-aware service protocols. We also present a composition language to handle dynamically the concurrent execution of protocols. This language addresses data dependency issues among several protocols concurrently executed on the same user device, using mechanisms based on data semantic matching. Our approach aims at assisting the user in establishing priorities between these dependencies, avoiding the occurrence of deadlock situations. Nevertheless, this process is error-prone, since it requires human intervention. Therefore, we also propose verification techniques to automatically detect possible inconsistencies specified by the user while building the data dependency set. Our approach is supported by a prototype tool we have implemented.Comment: In Proceedings FOCLASA 2010, arXiv:1007.499
