Game based training has gained a lively interest within the industry. We present a interdisciplinary work on the application of computer game principles and techniques within an automation industry training scenario. A data flow based component architecture forms the technical foundation of our system and enables us to exploit the capabilities of available middleware components like game- or physics engines. An interactive simulation of a real automation plant is built by the combination of state-based and physical object behavior. A model of training scenarios founded on the didactical principles of game based training is built upon our implemented system.

3D model reconstruction is an important issue in computer graphics, computer vision and virtual reality. This paper presents a new method in rapid reconstruction of detailed 3D surface models from a small number, e.g. 3-4, of 2D silhouettes of objects taken from different views. A statistical shape model is used to fit a set of landmarks points, which are automatically created from the 2D silhouettes, to reconstruct a full detailed surface. The landmark points are optimally distributed to guarantee that the salient features of objects are included in the reconstruction process. Some proof- of-concept computational experiments have been conducted to reconstruct a test object. The results show that the proposed method is capable of reconstructing an acceptable detailed 3D surface.

In this paper, we present a prototype Virtual Welding Simulator, which supports interactive training of welding process by using multimodal interface that can deliver realistic experiences. The goal of this research is to overcome difficult problems by using virtual reality technology in training tasks where welding is treated as a principal manufacturing process. The system design and implementation technical issues are described including real-time simulation and visualization of welding bead, providing realistic experience through 3D multimodal interaction, presenting visual training guides for novice workers, and visual and interactive interface for training assessments. According to the results from an initial user study, the prototype VR based simulator system appears to be helpful for training welding tasks, especially in terms of providing visual training guides and instant training assessment.

This paper presents a sketch-based modeling system with auxiliary planes as references for 3D freeform shape design. The user first creates a rough 3D model of arbitrary topology by sketching some contours of the model. Then the user can use sketching to perform deformation, extrusion, etc, to edit the model. To regularize and interpret the user's inputs properly, we introduce some rules for the strokes into the system, which are based on both the semantic meaning of the sketched strokes and human psychology. Unlike other sketching systems, all the creation and editing operations in the presented system are performed with reference to some auxiliary planes that are automatically constructed based on the user’s sketches or default settings. The use of reference planes provides a heuristic solution to the problem of ambiguity of 2D interface for modeling in 3D space. Examples demonstrate that the presented system can allow the user to intuitively and intelligently create and edit 3D models even with complex topology, which is usually difficult in other similar sketch-based modeling systems.

This paper analyses the Spatial Model of Interaction, a model that rules the possible interactions among two objects and that has been widely accepted and used in many CVE systems. As a result of this analysis, some deficiencies are revealed and a new model of interaction is proposed. Additionally, a prototype illustrating some of the best features of this model of interaction is detailed.

In this paper, novel methods for facial emotion recognition in facial image sequences are presented. Our facial emotional feature detection and extracting based on Active Appearance Models (AAM) with Ekman’s Facial Action Coding System (FACS). Our approach to facial emotion recognition lies in the dynamic and probabilistic framework based on Dynamic Bayesian Network (DBN) with Kalman Filter for modeling and understanding the temporal phases of facial expressions in image sequences. By combining AAM and DBN, the proposed method can achieve a higher recognition performance level compare with other facial expression recognition methods. The result on the BioID dataset show a recognition accuracy of more than 90% for facial emotion reasoning using the proposed method.

Recently, EEG-based technology has become more popular in “serious” games designs and developments since new wireless headsets that meet consumer demand for wear ability, price, portability and ease-of-use are coming to the market. Originally, EEG-based technologies were used in neurofeedback games and brain-computer interfaces. Now, such technologies could be used in entertainment, e-learning and new medical applications. In this paper, we review on neurofeedback game designs and algorithms, and propose design, algorithm, and implementation of new EEG-based 2D and 3D concentration games. Possible future medical applications of the games are discussed.

Haptic interaction is commonly used with 3D objects defined by their geometric and solid models. Extension of the haptic interaction to 3D Cyber worlds is a challenging task due to the Internet bandwidth constraints and often prohibitive sizes of the models. We study how to replace visual and haptic rendering of shared 3D objects with 2D image visualization and 3D haptic rendering of the forces reconstructed from the images or augmenting them, which will eventually simulate realistic haptic interaction with 3D objects. This approach allows us to redistribute the computing power so that it can concentrate mainly on the tasks of haptic interaction and rendering. We propose how to implement such interaction with small function descriptions of the haptic information augmenting images and video. We illustrate the proposed ideas with the function-based extension of VRML and X3D.

Nonverbal synchrony is an important and natural element in human-human interaction. It can also play various roles in human-computer interaction. In particular this is the case in the interaction between humans and the virtual humans that inhabit our cyber worlds. Virtual humans need to adapt their behavior to the behavior of their human interaction partners in order to maintain a natural and continuous interaction synchronization. This paper surveys approaches to modeling synchronization and applications where this modeling is important. Apart from presenting this framework, we also present a quantitative method for measuring the level of nonverbal synchrony in an interaction and observations on future research that allows embedding such methods in models of interaction behavior of virtual humans.
