520 $a This thesis contributes to addressing two important questions related to haptic rendering: how to reduce computation and how to apply haptic rendering to enhance the efficiency in the design process.
520 $a This thesis proposes two methodologies for reducing computation in haptic rendering, one from the viewpoint of modeling techniques; the other from the viewpoint of human force perception. For the former, we propose a new level-of-detail technique to reduce computation on a mass-spring model, based on the observation that the user focuses on the local contact area when interacting with a simulated deformable object. Higher levels of detail in the local area offer the user better realism, while keeping the complexity of the whole object under control. The latter methodology we propose is based on our analysis of the human perception of force. The hypothesis is that humans will not be able to distinguish two objects with different levels of detail, if the level of mesh refinement for each object exceeds a certain threshold.
