✦ Synopsis

In this paper we investigate attraction techniques, using the haptic modality, for CAD applications. An important issue in CAD systems is the modification of the Boundary Representation (B-Rep) of 3D objects. However, this fundamental task is possible only if a geometric element (vertex, edge, face) has already been selected. This paper focuses on a generic force feedback model of haptic attraction for CAD applications. Our model is flexible and allows the experimentation of several behaviours. Several evaluation studies are carried out to compare the impact of the model parameters on the user performance and comfort of use.
