In this paper, we introduce a novel interface, the Tangible Spin Cube, for experiencing a 3D ring menu in real space. It enables a tangible object-referenced 3D ring menu and its items’ placement by using multimarker tracking. Also, it supports spin interaction using hall sensor-based spin detection for natural menu browsing. Finally, we evaluate the performance of the current prototype’s spin detection and show an example of a 3D ring menu application.
