Abstract: We proposed the virtual carving system using the chisel device in a mixed reality (MR) space. Using this system,
users can carve on the virtual surface superimposed onto a real object, just as the real world. However, the carving in the realworld has some issues; for example, carving complex patterns require some skills and the real world carving does not allow
redo/undo carved patterns. In this paper, we show some functions to support such issues on carving complex patterns.
