In information visualisation, zoomable user interfaces (ZUI) were developed in order to navigate in a big information space. They have an infinite space and allow the manipulation of infinite pans and zooms but the main drawback is the risk of getting lost in the information space. Understanding how a human being perceived the scale changes and how he is living this “zoomable” experience will help to avoid the user disorientation when he manipulate this kind of interfaces. While basing on ecological and enactive theories, we will try to bring some elements of responses in order to understand the navigation in ZUI.

The objective of this work concerns the design and the implementation of a zoomable interface implying the haptic modality. The initial postulate is that the zoom experience is not a natural, a direct experience, but supposes instrumentation and learning. In other words, the zoom experience is built by the appropriation of a technical substitution which makes it possible to modify the properties of the space-time flow; these properties which bind the subject to his (real or virtual) world are relational. To conceive this new interface, directly inspired from technologies known as of sensory substitution, we carried out a set of experiments allowing to define and to qualify the technical conditions and of use which favour the emergence of a perceptive experience of the zoom type. More generally, it concerns the proposition of more intuitive or immediate modes of instrumental interaction engaging explicitly the body in action.

In this study, we mentions the first results concerning the validity of the 2/3 power law for shapes explored by Tactos, a sensory substitution device.

Studies using the sensory substitution devices reveal that perceptive activity itself is embodied in a living body capable of movement and possessing its own spatial dimensions. To study the conditions of a prosthetic perception, we developed a minimal device, Tactos, which carries out a coupling between the pen of a graphics tablet and tactile sensory stimulators. This system allows subjects to explore virtual tactile pictures and is intended to give to blind people an access to computer graphics. We will present here experimental results regarding the different aspects of perception using this device.
