This paper reports on our progress and findings in building a Web annotation system for non-immersive 3D virtual environments. Over the last two years, we developed and tested two systems for collaborating designers to comment on virtual 3D models. Our first system, Redliner [12] lets design team members browse and leave text annotations on surfaces in three-dimensional models. Experience with Redliner, including two user evaluations in different settings, led us to develop Space Pen [13], a second annotation system with improved interaction capabilities. It goes beyond the post-it note metaphor, allowing users to draw in and on the virtual environment.

We present the beginnings of a Cognitive Theory of Creativity Support aimed specifically at understanding novices and their needs. Our theory identifies unique difficulties novices face and reasons that may keep them from engaging in creative endeavors, such as fear of failure, time commitment, and lack of skill. To test our theory, we use it to analyze existing creativity support tools from multiple domains. We also describe the design and initial implementation of a creativity support tool based on our theory. The creativity support tool, called StorySketch, is designed to empower storytellers without graphical skills to engage in visual storytelling.
