Virtual reality (VR) technologies have recently been applied to traditional arts and industrial area. In painting field, there are several researches to make realistic brushes and pens for drawing and calligraphy. However, a realistic method with a haptic device still has not been implemented yet. In this paper, we propose a virtual calligraphic brush model for a haptic device to enable a natural drawing. We observed force variation of a writing brush, and make our model based on a spring-dumper model. Area of grounded brush, compression power, and friction force were considered. The implemented VR calligraphy system is evaluated by experiments, and it is shown that the proposed model can achieve realistic calligraphy feelings.
