ABSTRACT
While research on non-photorealistic rendering is providing simulation-based realistic watercolor painting effects, the current digital painting interfaces are yet to be improved for providing realistic watercolor painting experience. This study proposes a digital watercolor painting interface to support real watercolor painting processes. We evaluated the new interface in comparison with a conventional digital watercolor painting interface with respect to effectiveness, efficiency, and satisfaction. The new interface was not different in terms of efficiency, but was shown to be more effective in that it enabled the users produce more satisfactory paintings than the conventional interface. It was also favored in terms of satisfaction. This result suggests that a user interface supporting real watercolor painting processes is important for the usability of a simulation-based digital watercolor painting system.
