- The purpose of the study reported in this paper was to compare three different types of interfaces providing: haptic information, graphic information, or combined haptic and graphic information in an easy menu selection task. The results suggested that the combined haptic and graphic interface was preferable to the graphic interface regarding accuracy, while both interfaces were fundamentally equal concerning completion time. The results also indicated that the combined haptic and graphic interface was less mentally demanding than either the graphic or the haptic interface. Solely haptic feedback obtained, without exception, worse results than the other cases.

- This paper introduces the multisense idea, with a special reference to the use of haptics in the medical field and, in particular, in the planning of total hip replacement surgery. We emphasise the integration of different modalities and the capability of the multimodal system to gather and register data coming from different sources.

A haptic interaction technique for volume images based on gradient diffusion

Konferensbidrag (refereegranskat)abstract
- The manual step in semi-automatic segmentation of medical volume images typically involves initialization procedures such as placement of seed-points or positioning of surface models inside the object to be segmented. The initialization is then used as input to an automatic algorithm. We investigate how such initialization tasks can be facilitated by using haptic feedback. This paper describes a haptic interaction technique based on gradient vector flow (GVF) that allows a user to feel object boundaries while still being centered inside the object. Our method is not limited to elongated structures, which is a common restriction for other approaches. Initial tests of the method shows encouraging results for differently shaped objects.
