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.
