Multimedia human computer interface for oriental calligraphies
Most researches on oriental calligraphies simulation are based on the texture rendering methods with input from pointing devices. However, the traditional way is by using the hairy brush which is not employed in these applications. In this paper, we proposed a novel multimedia human computer interface that allows users which including artists to use the physical hairy brushes to write without training, so as to provide the same user experience. A virtual paper is projected on the transparent screen, the interface for using the hairy brush. An infra-red camera is used in capturing the image as the system input. A software framework was proposed to compute the contact region and the ink absorption between the ink-brush and the virtual paper. This information is highly useful in further rendering the texture of the brushstrokes and the ink spreading on the paper.
