“…This is usually done by the lecturer in the classroom, when explaining the animation being run, but an oral explanation is not usually available in simulations provided on-line. Other researchers have tried to activate other channels, for example, using color to code animation objects, or using sound effects to make users "hear" their data or programs (DiGiano & Baecker, 1992a, 1992bFrancioni, Albright, & Jackson, 1991;Gaver, O'Shea, & Smith, 1991).…”

This article is a review of the pedagogical experience obtained with systems for algorithmic animation. Algorithms consist of a sequence of operations whose effect on data structures can be visualized using a computer. Students learn algorithms by stepping the animation through the different individual operations, possibly reversing their effect. Algorithmic animation seems to improve the student's understanding of algorithms, but mainly when they can become active participants, not just spectators. Students who write their own algorithmic animations are more engaged and can profit more from them. At the end of this article, we extract some consequences for the development of future algorithmic animation systems.

“…Le son a toujours été utilisé pour illustrer des fonctions systèmes [5], [7], [10], pour le débuggage [8], [9] ou dans les interfaces utilisateurs sonores ou multimodales [3], [13], [15]. Plus récemment, l'audio 3D est devenu de plus en plus sollicité par les domaines comme la ré-alité augmentée, les applications portables, pro-actives ou envahissantes (« pervasive applications ») [4].…”

RESUMEAvec l'émergence de l'internet mobile et des nouvelles générations d'ordinateurs portables ultra-mobiles ( ou « wearable PCs »), il est incontestable que nous entrons dans une ère nouvelle où les systèmes informatiques vont adapter leurs ressources au corps, à l'esprit et aux préférences de l'utilisateur humain. Il sera donc plus aisé pour un utilisateur d'énoncer des commandes indépendamment des implications matérielles et procédurales requises pour son exécution ; l'ordinateur s'en occupe comme un réel assistant. Dans le contexte de ce nouveau mode d'interaction homme-machine, nous proposons un modèle de présentations d'interfaces utilisateurs basées sur la spatialisation du son (ou audio 3D) et qui tient compte de la mobilité de l'usager et de la portabilité du matériel. Dans le cadre de ce papier, nous illustrons notre travail par des présentations d'informations extraites automatiquement de la toile (nouvelles, informations météorologi-ques et économiques) qui sont spatialisées avant d'être présentées à des utilisateurs mobiles dotés d'oreillettes permissives pour les écouter. MOTS CLES :Interface utilisateur avancée, audio 3D, spatialisation du son, mobile, portable ultra-mobile, portable ultra-léger. ABSTRACTWith the emergence of the mobile Internet combined with wearable personal computing, we are now entering a new information era where PCs are self-adapting their resources to human bodies, minds and preferences, prevailing a more effective work environment. In this new world, working effectively is inextricably related to accessing reliable information sources anytime and anywhere. In this paper, we propose innovative UI news presentations based on three-dimensional (3-D) audio modeling.We illustrate how news, weather and business reports are extracted, spatialized and presented to mobile users wearing permissive earsets.

“…Sounds have proven effective as a way to represent multi-variate data in studies with botanical classification [15], monitoring a patient during surgery [16], the analysis of sociological data [13], atmospheric chemistry [4], and debugging parallel computer programs [12]. The potential for real-time interactive sonification in virtual environments was demonstrated with chaotic data at the NCSA [9].…”

This paper describes tools and techniques for the exploration of geo-scientific data from the oil and gas domain in stereoscopic virtual environments. The two main sources of data in the exploration task are seismic volumes and multivariate well logs of physical properties down a bore hole. We have developed a props-based interaction device called the cubic mouse to allow more direct and intuitive interaction with a cubic seismic volume. This device effectively places the seismic cube in the user's hand. Geologists who have tried this device have been enthusiastic about the ease of use, and were adept only a few moments after picking it up.We have also developed a multi-modal visualisation and sonification technique for the dense, multivariate well log data. The visualisation can show two well log variables mapped along the well geometry in a bivariate colour scheme, and another variable on a sliding lens. A sonification probe is attached to the lens so that other variables can be heard. The sonification is based on a Geigercounter metaphor that is widely understood and which makes it easy to explain. The data is sonified at higher or lower resolutions depending on the speed of the lens. Sweeps can be made at slower rates and over smaller intervals to home in on peaks, boundaries or other features in the full resolution data set.
