We are also interested by the relations between image, sound, gesture and the perception of movement within the context of virtual environments and technological convergence. A perspective to explore in the mobile phone and nomad technologies would be to conceive sound and image as a signal (we oppose here sign and signal). Image would express rythms, temporality and others characteristics tradionally linked to music. We have then to explore the concept of intersensoriality: how to compose with sound and images, a visual music? We could start with a study of the relations of complementarity between sound and image. How the visual can help to listen to the spatialisation of sound? Can the spatialisation of sound contribute to enhance a visualisation? How much a sound loose its perceptive importance as soon as it is visualised? Where is the threshold beyond which the image perception take over the musical perception? Is there a level between sign and signal?
