Interaction naturelle avec une scène virtuelle de micromanipulation

Abstract : Micromanipulation is an important tool for recent developments in microscale production, characterization and analysis. However, micromanipulation systems and interfaces are not widely used in the research field or in the industry. They remain unhandy and complex to manage from the user’s point of view. Hence, the operator has to learn a complex symbolic language to communicate with the interface, like clicking on specific buttons or performing gestural or vocal commands. The objective of this work is to propose more natural interfaces dedicated to micromanipulation. To overcome these limitations, three aspects are addressed: •An intuitive simulator for a typical micromanipulation task with an AFM cantilever is implemented. The complexity of the real system is masked. The objective is to introduce a simulator suitable for non-expert users. •To detect the decision to grab or drop an object, a non symbolic model of intention prediction inspired by cognitive science is proposed. It exploits targeted gesture invariants on velocity assuming that the target is known. •A selection method is proposed to adapt the achieved results to realistic contexts where the target position is not known a priori. This model exploits the direction of motion of the gesture and the gaze to activate a dynamic neural field. The main bubble of activity within the field corresponds to the user's focus of attention. The results show a significative quantitative and qualitative improvement compared with classical approaches to detecting decisions. This work shows the contribution of non symbolic interaction approaches for new user-centered interfaces.
