Abstract
Using Atomic Force Microscopes (AFM) to manipulate nano-objects is an actual challenge for both physicians and biologists. Many visual and haptic interfaces between the AFM and experimentalists have already been implemented. The multi-sensory renderings (seeing, hearing, feeling) studied from a cognitive point of view increase the efficiency of the actual interfaces and represent our challenge. To allow the experimentalist to feel and touch the nano-world, we add mixed realities between an AFM and a force feedback device, enriching thus the direct connection by a modeling engine. The functionality of an AFM is described in this paper through physical and energetic analogies. Firstly, we present a physical model, able to be simulated in real time that allows user to feel in his fingers and act on the virtual scene of a nano-world. The existing force between the AFM tip and the nano-surface in a cohesive interaction is transmitted to the experimentalist in real time through the designed model and the Force Feedback Gestural Device, making thus possible a human haptic perception of the approach-retract interaction. This minimal representation of the real and complex phenomenon of approbation interaction is then strengthened and validated by an electro-mechanical model, through which we integrate functional AFM components in a Simulink model. Secondly, we describe the same interactions from the dual energetic point of view. This
