“…Les autres paramètres contrôlables par l'utilisateur, à gauche de l'interface, sont le rayon de la sphère de filtrage (permettant de ne sonifier que les points situés à l'extérieur de cette sphère) et la vitesse de parcours de la protéine du centre vers l'extérieur (durée totale de lecture). La spatialisation du rendu sonore suit un procédé d'ambisonique virtuel [13], avec un encodage ambisonique d'ordre 3 et un décodage en binaural pour une restitution sur casque. Le rendu ambisonique est effectué avec la librairie HOA du CICM [17].…”

Afin d'étendre les modes de visualisation de protéines déjà disponibles, nous présentons ici une nouvelle approche de sonification permettant de représenter la surface d'une protéine par du son. A chaque point de la surface discrétisée est associée une source sonore, dont les paramètres sonores sont liés à la protéine, spatialisée de sorte que l'utilisateur soit immergé au centre de la protéine. Un système de filtrage interactif, sous la forme d'une sphère de rayon réglable par l'utilisateur, permet de sélectionner les points de la surface qui seront lus afin d'améliorer l'interprétation auditive de la forme 3D. Plusieurs questions, pouvant bénéficier à la communauté IHM, sur la mise en place de filtrages sonore et audiovisuel d'informations et sur l'optimisation des combinaisons multimodales issues de points de vue et écoute différents sont exposées. Mots Clés Sonification interactive; Audio 3D; Objets 3D; Surface de protéines AbstractTo extend pre-existing protein visualisation methods, we present a new approach of immersive sonification to represent protein surfaces through sound. The protein surface is first discretized so each point of the surface is attached to a sound source spatialized in such a way the user is im-mersed in the center of the protein. We add a spherical filtering system, that the user can control, to select the surface points that would be rendered in order to reinforce the auditory interpretation of the 3D shape. Several questions, which can benefit the HCI community, are discussed both on audio and audiographical filtering consistency, and on multimodal integration of data coming from different point of view and point of listening.

“…An extensive literature is now available on the theory and applications of Ambisonics. Some of the relevant publications are, among others, [Fel75], [CG77], [Mal99], [Cot02], [Wig04], [SS06], [Sol08], [HS09], [AS08a], [AS08b], [AS08c], [SA08], [MAA07], [ZPF09], [SH01], [NMSH03], [FU98] and [HLB08] In the work of Daniel et al [DNM03] it is reported that Ambisonics is based on the The decoding procedure discussed above is usually referred as basic decoding. Other decoding strategies have been proposed, such as the in-phase decoding or the energy vector maximization decoding (see for example [Dan00]).…”

“…The solution is not ready yet, but a promising way of sound field reference data is using spatial data formats that form an intermediate step from the spatial sound field to binaural signals. If the directional sound field is known, its transformation into binaural signals can be done subsequently and individually (Meyer, & Elko, 2002) (Noisternig, Sontacchi, Musil, & Höldrich, 2003) (Song, Ellermeier, & Hald, 2008). The spatial sound field is, thus, a basis for postprocessing in various applications in general.…”

The conditions of sound fields used in research, especially testing and fitting of hearing aids, are usually simplified or reduced to fundamental physical fields, such as the free or the diffuse sound field. The concepts of such ideal conditions are easily introduced in theoretical and experimental investigations and in models for directional microphones, for example. When it comes to real-world application of hearing aids, however, the field conditions are more complex with regard to specific stationary and transient properties in room transfer functions and the corresponding impulse responses and binaural parameters. Sound fields can be categorized in outdoor rural and urban and indoor environments. Furthermore, sound fields in closed spaces of various sizes and shapes and in situations of transport in vehicles, trains, and aircrafts are compared with regard to the binaural signals. In laboratory tests, sources of uncertainties are individual differences in binaural cues and too less controlled sound field conditions. Furthermore, laboratory sound fields do not cover the variety of complex sound environments. Spatial audio formats such as higher-order ambisonics are candidates for sound field references not only in room acoustics and audio engineering but also in audiology.
