Enjoyable carving with ChiselDevice in mixed reality space

In this paper, we propose a system that can carve virtual objects in Mixed Reality (MR) space. The procedures of real-world carving include sculpting a rough outline, shaping sections, and carving patterns onto an object's surface. Of these, we focus on the procedure for carving patterns. Users of our system stroke a real object directly using ChiselDevice, and the surfaces of 3D virtual objects superimposed on the real object are "carved." This paper describes the design and development of the ChiselDevice and the MR carving system and the findings of users' experiences of our system.
