Abstract
Surface visualizations are essential in analyzing three-dimensional spatiotemporal phenomena. Given its ability to provide enhanced spatial perception and scene maneuverability, virtual reality (VR) is an essential medium for surface visualization and interaction tasks. Such tasks primarily rely on visual cues that require an unoccluded view of the surface region under consideration. Haptic force feedback is a tangible interaction modality that alleviates the reliance on visual-only cues by allowing a direct physical sensation of the surface. In this paper, we evaluate the use of a force-based haptic stylus compared to handheld VR controllers via a between-subjects user study involving fundamental interaction tasks performed on surface visualizations. Keeping a consistent visual design across both modalities, our study incorporates tasks that require the localization of the highest,…
