Synthèse et commande de dispositifs haptiques pour la communication à distance : application à une interface robotique anthropomorphe pour la poignée de main
|Abstract:||Remote communication systems have significantly improved in the course of the recent years, in concert with technological innovations of our society. In order to realize a realistic and intuitive communication, the system must activate the part of the sensory system that is normally stimulated in an interaction between two people, i.e., the auditory system, the visual system and the haptic perception system, which concerns touch. The telephone represented an innovating communication system. It allowed to directly talk to the interlocutor without any need for a coded signal such as the Morse code. Remote communications have been further improved with the introduction of the video calls, which allow people not only to talk to but also to see each other. Several researches proved that the sense of touch plays a crucial role in social interactions. Haptic technology, which is relatively recent, approaches the problems related to the perception and the transmission of touch. One objective is to render remote communications even more complete and realistic. Haptic technology is also used in other important applications such as, for instance, rehabilitation and guided learning process of people with movement impairments. This thesis concerns the development of the haptic technology devoted to the implementation of remote communication systems. The final objective is to realize a teleoperation system which allows two users to remotely shake hands. In order to achieve this objective, two main issues must be faced : the design of a haptic interface capable of reproducing the required movement and the implementation of a control law which guarantees the proper response of such an interface. In the framework of a remote interaction via a haptic device, an interface for the training and assessment of handwriting capabilities is also presented. The latter application demonstrates the importance of haptic signals in a remote human-human interaction and its influence on the users.|
