Sketching-out virtual humans: From 2d storyboarding to immediate 3d character animation

Virtual beings are playing a remarkable role in today’s public entertainment, while ordinary users are still treated as audiences due to the lack of appropriate expertise, equipment, and computer skills. In this paper, we present a fast and intuitive storyboarding interface, which enables users to sketch-out 3D virtual humans, 2D/3D animations, and character intercommunication. We devised an intuitive “stick figurefleshing-outskin mapping” graphical animation pipeline, which realises the whole process of key framing, 3D pose reconstruction, virtual human modelling, motion path/timing control, and the final animation synthesis by almost pure 2D sketching. A “creative model-based method” is developed, which emulates a human perception process, to generate the 3D human bodies of variational sizes, shapes, and fat distributions. Meanwhile, our current system also supports the sketch-based crowd animation and the storyboarding of the 3D multiple character intercommunication. This system has been formally tested by various users on Tablet PC. After minimal training, even a beginner can create vivid virtual humans and animate them within minutes

TLAD 2010 Proceedings:8th international workshop on teaching, learning and assesment of databases (TLAD)

This is the eighth in the series of highly successful international workshops on the Teaching, Learning and Assessment of Databases (TLAD 2010), which once again is held as a workshop of BNCOD 2010 - the 27th International Information Systems Conference. TLAD 2010 is held on the 28th June at the beautiful Dudhope Castle at the Abertay University, just before BNCOD, and hopes to be just as successful as its predecessors.The teaching of databases is central to all Computing Science, Software Engineering, Information Systems and Information Technology courses, and this year, the workshop aims to continue the tradition of bringing together both database teachers and researchers, in order to share good learning, teaching and assessment practice and experience, and further the growing community amongst database academics. As well as attracting academics from the UK community, the workshop has also been successful in attracting academics from the wider international community, through serving on the programme committee, and attending and presenting papers.This year, the workshop includes an invited talk given by Richard Cooper (of the University of Glasgow) who will present a discussion and some results from the Database Disciplinary Commons which was held in the UK over the academic year. Due to the healthy number of high quality submissions this year, the workshop will also present seven peer reviewed papers, and six refereed poster papers. Of the seven presented papers, three will be presented as full papers and four as short papers. These papers and posters cover a number of themes, including: approaches to teaching databases, e.g. group centered and problem based learning; use of novel case studies, e.g. forensics and XML data; techniques and approaches for improving teaching and student learning processes; assessment techniques, e.g. peer review; methods for improving students abilities to develop database queries and develop E-R diagrams; and e-learning platforms for supporting teaching and learning

Public HMDs: Modeling and Understanding User Behavior Around Public Head-Mounted Displays

Head-Mounted Displays (HMDs) are becoming ubiquitous; we are starting to see them deployed in public for different purposes. Museums, car companies and travel agencies use HMDs to promote their products. As a result, situations arise where users use them in public without experts supervision. This leads to challenges and opportunities, many of which are experienced in public display installations. For example, similar to public displays, public HMDs struggle to attract the passer-by's attention, but benefit from the honeypot effect that draws attention to them. Also passersby might be hesitant to wear a public HMD, due to the fear that its owner might not approve, or due to the perceived need for a prior permission. In this work, we discuss how public HMDs can benefit from research in public displays. In particular, based on the results of an in-the-wild deployment of a public HMD, we propose an adaptation of the audience funnel flow model of public display users to fit the context of public HMD usage. We discuss how public HMDs bring in challenges and opportunities, and create novel research directions that are relevant to both researchers in HMDs and researchers in public displays

Rivale: A Prototype realistic Immersive Virtual Agent-Based Learning Environment Case Study for Learning Requirements Elicitation Skills

Current ways of teaching requirements analysis, such as paper-based case studies, do not sufficiently support development of skills to investigate a problem situation. This paper reports on research to develop and evaluate an initial prototype of a Realistic Immersive Virtual Agent-based Learning Environment (RIVALE) virtual case study. The example fictional case study in this paper would be used as an exercise for students taking a systems analysis and design class to practice and learn requirements elicitation skills, such as interviewing, questionnaires, document review, form review, and observation. The intention is to provide a more realistic experience and to thereby support better learning as well as more realistic assessment of and feedback concerning student skills in requirements elicitation. The requirements, design, implementation, and initial, lightweight evaluation of the initial prototype are described. The initial prototype shows promise, but specific issues, especially problems with achieving realistic conversation, are identified and recommendations for further research are provided.

Essential Feature - Cooperative Gameplay

Although single player and multiplayer is very important in today game, cooperative mode is an essential part of a great game. There are a lot of benefits of playing co-op mode in a game such as education and joy. Communicating, solving problems, handling stress, managing time, making decision, following instructions, acting fast as well as working in a team are skills that students can learn and practice while they are playing cooperative games. These skills are valuable for students to use in education and even in careers

The Durham difference: considering our context

This article reflects on the experience of Durham University Library staff in promoting services as part of undergraduate induction. It challenges the perception that all methods of marketing are equally valuable to all institutions and explores some alternatives

VR Exergames for ocular diseases diagnosis

According to the World Health Organization, in 2011 there were about 314 million people with impaired vision, due either to ocular diseases or uncorrected ocular errors. Around 45 million people, of these 314 million, are blind. About 75% of all blindness and visual impairment cases caused by these diseases are avoidable. There are already some practical and relatively cheap tools to make this diagnosis, but all of them are intrusive, which doesn’t make them too attractive. To solve this issue, we thought of a non-intrusive way to diagnose eye problems. So we created a Virtual Reality exergame, EyeCare, that tests users’ vision, while they are having fun playing it. This exergame is meant to be played by teenagers and young adults, using only a smartphone and Virtual Reality visor. EyeCare consists in a game where users have to complete several puzzles to escape the forest. The users play the puzzles to assess their astigmatism, contrast sensitivity, color blindness, and peripheral vision. In the end, the results are given to the users as problems that they may have. With this solution, our goal is to diagnose diseases early enough, so they can be monitored, and thus reducing the number of people with impaired vision and blindness
