Interactive Stroke-Based NPR using Hand Postures on Large Displays

Description:

We explore the use of hand postures to interact with stroke-based rendering (SBR) on touch-sensitive large displays. In contrast to traditional WIMP interfaces, we allow people to directly engage with and influence a rendering. Our system allows the creation of new stroke primitives as well as provides mechanisms to distribute and then manipulate them on the canvas. We offer a set of natural mappings from hand postures to rendering parameterizations. The resulting system allows an intuitive exploration of SBR without the need for traditional desktop interfaces.

Demo:

You can download a demo of the Hand-Posture based Interactive Stroke-Based NPR (Win32, 9.1 MB) and try it out for yourself. To be fully functional, however, the demo requires Smart DViT hardware.

This technique is based on a buffer framework for supporting responsive interaction and was later used for interacting with glyph-based 2D vector data visualizations.
