Article
Full-text available
This paper is dedicated to the study of existing approaches that explicitly use mental simulation. Current implementations of the mental simulation paradigm, taken together, computationally address many aspects suggested by cognitive science research. Agents are able to find solutions to nontrivial scenarios in virtual or physical environments. Exi...
Conference Paper
Full-text available
Using mental simulation as a means of selecting actions for an agent is not new to the scientific community, but implementations from literature focus on specific scenarios and strategies built by domain-experts. In this paper, we propose a generic decision-making agent architecture which uses mental simulation. Our architecture allows an agent to...

We investigate the decision-making and behavior of robotic biped goalkeepers, applied to the RoboCup 3D Soccer Simulation League. We introduce two approaches to the goalkeeper’s behavior: first a heuristics-based approach that uses linear regression and Kalman filters for improved perception, and another based on mental models which uses nonlinear...
Conference Paper
Full-text available
Believability of automated characters in virtual worlds has posed a challenge for many years. In this paper, the author discusses a novel approach of using human-inspired mirroring behavior in MirrorBot, an Unreal Tournament 2004 game bot which crossed the humanness barrier and won the 2K BotPrize 2012 competition with the score of 52.2%, a record...
Article
Full-text available
Simulation is widely used to make model-based predictions, but few approaches have attempted this technique in dynamic physical environments of medium to high complexity or in general contexts. After an introduction to the cognitive science concepts from which this work is inspired and the current development in the use of simulation as a decision-...

We posit that human-robot interfaces that integrate multimodal communication features of a 3-dimensional graphical social virtual agent with a high degree of freedom robot are highly promising. We discuss the modular agent architecture of an interactive system that integrates two frameworks (our in-house virtual social agent and robot agent framewo...

Object detection is crucial for autonomous robotic systems to interact with the world around them but, in robots with low computational resources, deep learning is difficult to take advantage of. We develop incremental improvements to related work on feature approximation and describe an adaptive fHOG feature pyramid construction scheme based on hi...
Conference Paper
Full-text available
Although socially interactive agents have emerged as a new metaphor for human-computer interaction, they are, to date, absent from the Internet. We describe the design choices, implementation, and challenges in building EEVA, the first fully integrated platform-independent framework for deploying realistic 3D web-based social agents: with real-time...
Preprint
Full-text available
Recent advances in haptic hardware and software technology have generated interest in novel, multimodal interfaces based on the sense of touch. Such interfaces have the potential to revolutionize the way we think about human computer interaction and open new possibilities for simulation and training in a variety of fields. In this paper we review s...
Conference Paper
Full-text available
Real time user independent facial expression recognition is important for virtual agents but challenging. However, since in real time recognition users are not necessarily presenting all the emotions, some proposed methods are not applicable. In this paper, we present a new approach that instead of using the traditional base face normalization on w...
Conference Paper
Full-text available
Video game development is not only one of the most profitable entertainment industries but also represents a very interesting field of research. Particularly in the area of Artificial Intelligence (AI), it provides many interesting (and hard to tackle) challenges. One of them consists in creating artificial bots (i.e., game characters not controlle...
Article
This article deals with artificial intelligence models inspired from cognitive science. The scope of this paper is the simulation of the decision-making process for virtual entities. The theoretical framework consists of concepts from the use of internal behavioral simulation for human decision-making. Inspired from such cognitive concepts, the con...
Conference Paper
We present in this work GRASPhere, a prototype device that enables users to select and manipulate on-screen objects with grasping gestures. We demonstrate GRASPhere as an extension of a widely-employed force-sensing device, the Phantom OMNI. The hardware design of GRASPhere employs a minimum of components that cost less than $20, which makes our pr...
Thesis
Full-text available
Interactive virtual environments pose a wide variety of challenges for intelligent agents, especially to make decisions in order to reach their goals. The difficulty of decision making tasks rises quickly when introducing continuous space and real time. It also becomes increasingly harder to build intelligent agents that can meaningfully interpret...
Conference Paper
Full-text available
User immersion inside an unfamiliar Virtual Environment can be significantly increased by exploring the possibilities of haptic technology. Claim: bidirectional physical interaction-where both, the user and the system, play an active role-could be the most efficient way to assist and engage the user. This paper consists in a comparison between thre...

Article
Full-text available
Any virtual environment (VE) built in a classical way is dedicated to a very specific domain. Its modification or even adaptation to another domain requires an expensive human intervention measured in time and money. This way, the product, that means the VE, returns at the first phases of the development process. In a previous work we proposed an a...

The paper presents some activities carried out within a project on the multimodal environment for cooperative and transnational education activities.
Conference Paper
Full-text available
This paper presents a physical user interface intended to help the user (or multiple simultaneous users) to achieve an intuitive movement inside a 3D environment without using common interaction devices such as mouse or keyboard, while stressing the aspect of reducing financial investments. After exposing an analysis of current solutions and implem...
Conference Paper
This paper deals with a project that aims at improving students engineering skills especially when the actors of the project, the tasks to be achieved and the knowledge, are distributed between several different countries. The goal is to obtain a digital environment that is capable of hosting distributed and cooperative practical activities for gro...

Virtual environments constitute the support platform for various teaching and learning activities. Instead of a local application for this purpose, this paper explores the effects of using distributed virtual reality environments in the educational process. The architecture of the presented system is based on the recently developed web-based techno...
Article
Full-text available
We discuss the effects of using distributed virtual reality environments in the educational process. Pedagogical, technical and implementation aspects are explored in conjunction with a virtual environment used in the engineering training curricula. Knowledge exchange occurs in the process of social interaction. The complexity of the actual knowled...

In the present contribution we shall introduce the IIUBAR system, which represents an Interactive Informative Unit Based on Augmented Reality technology (AR), provided by the Augmented Reality Toolkit (ARToolkit) API. After invoking the potential of the proposed system in educational contexts, theoretical concept behind the ARToolkit package as wel...
