This paper describes the development of a framework that allows virtual object contact sounds to be synthesised in real time from information provided by a governing physics engine at physics refresh rate. The objects can be modified during run-time by their physical or perceptual parameters and both impact and continuous contact sounds can be created. The new contributions are features designed to...
In this paper we provide preliminary results on a new modeling approach for improved determination of facial expressions from a low-resolution video stream. An initial proof-of-concept using an extension of an Active Appearance Model (AAM) to measure facial parameters and a set of classifiers to determine facial states are described. We also discuss the potential for applying this technique to determine...
Techniques for improved 2D active appearance face models are presented. When these are applied to stereoscopic image pairs we show that sufficient information on image depth is obtained to generate an approximate 3D face model. Two techniques are investigated, the first based on 2D+3D AAMs and the second using methods based on thin plate splines. The resulting 3D models can offer a practical real-time...
In order to develop the core chip supporting binocular stereo displays for head-mounted display (HMD) and glasses-TV, a VLSI design scheme is proposed by using pipeline architecture for 3D display processing chip (HMD100B). Some key techniques including stereo display processing and high precision video scaling based on bicubic interpolation, and their hardware implementations are presented. A new...
Real-time camera tracking is steadily gaining in importance due to the drive from various applications, such as AR(augmented reality), human-machine interface, and ubiquitous computing. However, a real-time camera tracking using a single camera in an unknown environment is not a trivial work. In this paper, we describe a real-time camera tracking framework specifically designed to track a monocular...
This paper presents a framework for building VideoPlace-like vision-driven user interface using ldquooptical flowldquo measurements and elastic labeled silhouette. The optical flow not only detects the movements but also gives us an estimate of the direction and the speed of the movement. The proposed representation is based on a self-organizing system designed to learn to recognize both the characteristic...
In this paper, we will introduce a fast and robust method of constituting a probability map by extracting foreground object from background image which is basic technology to be applied to vision-based real-time game interaction. We implement a neural network with one hidden layer to recognize a motion of the probability map. In this process, we extract the foreground probability map which is robust...
Multi-agent system of autonomous interactive blocks that can display its active state through color and light intensity has been developed. Depending on the individual rules, these autonomous blocks could express emergent behaviors which are a basis for various educational games. The multi-agent system is used for developing games for behavioral training of autistic children. This paper features the...
In recent years there has been significant growth in the use of 3D virtual worlds for e-learning and distance education. These immersive environments offer the ability to create complex, highly interactive simulations using in-world modeling and scripting tools. Virtual learning environments' support teaching and learning in an educational context, offering the functionality to manage the presentation,...
This paper presents an application in which a feedforward neural network is trained by mathematics students to solve mathematical problems. The interface is designed as an educational computer game to help the students understand GCSE mathematics. A demonstration of the idea, using Matlab, is discussed and the results show that the idea is workable. The possibility of using evolutionary neural networks...
This paper describes the motivation and application of a Microsoft XNA extended library- XQUEST (XNA QUick & Easy Starter Template) in a software architecture course. Further, it presents the evaluation of the usability and usefulness of the XQUEST library in the context of a software architecture course. XQUEST was designed and implemented to save students' time in development projects offering...
In 2008, a game development project was introduced in a software architecture course at the Norwegian University of Science and Technology. The motivation for introducing the project was to let students learn how software architecture practices and processes can improve the final product in an inspiring and practical way. In the project, students organized in groups had to establish functional and...
Mobile culture refers to an increasingly important role that mobile communication and mobile media play in our everyday lives. Young people are often viewed as the driving force behind the innovation in mobile technology, since they comprise the majority of early adopters and most avid users of mobile gadgets and applications, especially mobile games. Many contemporary college students grew up surrounded...
Combined forces service interventions in the UK illegal drug market can be designed and evaluated using a serious game, where the illegal drug market can be simulated using an agent-based model with a large number of different classes of human behaviour. This paper presents NARCSim the Intelligent-ABM that used to power the illegal drug market serious game under construction. NARCSim is an Agent-Based...
Runesinger is a demo of a PC videogame to speak and spell Korean. The player practices a few nouns and verbs by serving food to hungry villagers during a North Korean famine. Inspired by melodic intonation therapy, the player sings a jingle. On each musical note, a ball bounces on an iconic syllable. Through a spelling puzzle, the player composes each syllable in Hangul, which is the phonetic alphabet...
