Biological tissues display a very complex spatial structure and their mechanical properties remain largely unexplored on the nanometer scale. We are building an interface that allows humans to explore the spatially complex data of nanomechanical force fields interactively and with multiple senses simultaneously (visual, auditory, and haptic). From a technological viewpoint, the multisensory display has to translate the user’s hand motion fluently and quasi in real time into a haptic, visual, and auditory presentation of the data. Avoiding a perceivable delay between the different display channels is essential, since humans are very sensitive to asynchronies between the senses and to delays between perception and action. Of equally high importance as the technical challenge is the question of how particular nanomechanical properties—such as different types of adhesive and repulsive forces—can be translated to the human senses and represented so that they can be efficiently explored. Here we report on our implementation of the multisensory interface, its multisensory information design, and perceptional evaluation studies.
