Interpersonal recognition through mediated tactile interaction

For several years, we have been developing a system of perceptual supplementation (Tactos) so as to render spatialized digital information accessible to users with visual deficiencies. After having validated this device in experimental situations and in practical use, we now propose to connect several Tactos systems in a network, so as to allow for access to shared digital spaces via the tactile modality (Intertact). This opening up of previously individual use to collective use makes it possible to conceive digital spaces designed for tactile interaction, by proposing practical, pedagogical and gaming functionalities. This new possibility of tactile interaction opens the way to the production of a technical aid for visually impaired persons with a social dimension. At the same time, the design of shared tactile spaces goes together with a fundamental reflection concerning perceptual interactions. We therefore propose an experimental study in order to provide the necessary steps to characterize the processes of mutual engagement in the interactions. The first results suggest that these processes seem to constitute a mutual dynamics, which is the basis for an active co-construction of meaning.
