Improving finger contact models for haptic interaction

Rasmus Buchmann, Leibniz Universität Hannover, diploma thesis

In the finished EU-research project HAPTEX, the Welfenlab developed a VR-system allowing the interaction between two fingers and a textile. For the interaction it was necessary to create a contact model for the objects simple enough to  maintain  a high update rate (~1kHz) for the computations driving the force feedback.

In this thesis work a more precise contact model has to be developed considering the common approaches in the field of contact mechanics. An analysis and comparison of the new model against the previous work should be conducted.
