Abstract:
In order to make the virtual environments(VE’s) more realistic and to increase human performance, the inclusion of haptic modality becomes more important. In this paper we present two new haptic guides. The haptic guides are fundamentally aimed to assist users for object selection in VE’s. We divide the virtual environment into three zones. In the first zone the user can freely move and don’t use any sort of guides. In the 2nd zone, user is given visual guidance and the 3rd zone contains haptic guides along with visual guides. As the paper presents two different models of the haptic guides, one for free and multidirectional selection and the second for precise and single direction selection. We not only study the effect of these guides on human task performance in the VE but also investigate a comparison of the two haptic models.
