Abstract: We introduce two new interaction techniques for creating and interacting with non-photorealistic images using strokebased rendering. We provide bimanual control of a large interactive canvas through both remote pointing and direct touch. Remote pointing allows people to sit and interact at a distance with an overview of the entire display, while direct-touch interaction provides more precise control. We performed a user study to compare these two techniques in both a controlled setting with constrained tasks and an exploratory setting where participants created their own painting. We found that, although the direct-touch interaction outperformed remote pointing, participants had mixed preferences and did not consistently choose one or the other to create their own painting. Some participants also chose to switch between techniques to achieve different levels of precision and control for different tasks.
