Abstract Programming education is very important in engineering education; however it is a challenge to find attractive issues for students that can motivate them. Students especially, need complex skills to develop new interactive projects that use noble devices. Kosaka, a lecturer of programming in the" Global Information Technology department at Kanazawa Technical College" which provides educations for game programming, application development project s and international language skills. Students' skills are not high at the ...

Abstract Recently, stable markerless 6 DOF video based handtracking devices became available. These devices simultaneously track the positions and orientations of both user hands in different postures with at least 25 frames per second. Such hand-tracking allows for using the human hands as natural input devices. However, the absence of physical buttons for performing click actions and state changes poses severe challenges in designing an efficient and easy to use 3D interface on top of such a device.

Abstract This paper describes an experiment conducted to study the influence of visual appearance of user's avatar (or 3D cursor) on the manipulation of virtual objects in virtual environments (VE). Participants were asked to pick up a virtual cube and place it at a random location in a VE. We found that one visual property of the avatar (the presence or absence of a directional cue) could influence the way participants picked up the cube in the VE.

Abstract We present redirection techniques that support exploration of large-scale virtual environments (VEs) by means of real walking. We quantify to what degree users can unknowingly be redirected in order to guide them through VEs in which virtual paths differ from the physical paths.

Abstract Capabilities of VR technologies grant a natural environment to researchers and engineers for the exploration of large data sets. During the last two decades several haptic rendering approaches have been developed in order to acquit the visual feedback and allow users to fully exploit the coupling of these two sensory channels. Some skilful results have been archived. In this paper we present a survey on the use of the haptic modality in large data sets exploration.

ABSTRACT. Researchers of the Ubiquitous Computing community (Ubicomp) have been pursuing the vision of a world where technologies and services permeates every object of our lives for years. With components getting smaller, cheaper and more powerful, it has become possible to manufacture connected objects capable of interacting with resources of the World Wide Web. This opens up the possibility for researchers and practitioners to consider information as a design material and objects as platforms for services.

Résumé-Dans cet article, il est question de décrire une méthode de conception d'artefacts issus des technologies émergentes telle la réalité virtuelle. Partant du constat que la phase d'identification des besoins n'est pas très détaillée dans les méthodes de l'ingénierie comparativement aux phases de réalisation technique, nous proposons d'améliorer une méthode d'ingénierie de conception de systèmes de réalité virtuelle: la méthode I²I.

ABSTRACT The growing number of tagged or Web-enabled objects today opens up the possibility for object-based applications or services to be designed. In this paper, we discuss the concept of an “object browser” for the Web of Things and present an Environment-based mobile Browser (EnvB) that facilitates the interactions with the resources (objects, services and people) of a physical place.

Abstract For many years, it was assumed that technical features were the most important ingredients to support an effective and efficient collaborative platform. Nowadays, ICT users are creating value in massively populating web applications and online role-playing games with their own activities and related data (ie eBay, Amazon, Linked-In, FaceBook, SecondLife, World-of-Warcraft).

Depuis l'avènement des premiers serious game expérimentaux dans les années 1980, le domaine n'a cessé de se développer et est désormais exploité par un large panel d'acteurs, des pédagogues aux publicitaires en passant par les industriels et les lobbyistes. Ce marché mondial des serious game, encore marginal au début des années 2000 a explosé pour se chiffrer à 52, 6 milliards de dollars en 2010 [1].
