Abstract:
We present a technique that combines the visual benefits of virtual enhancement
with the intuitive interaction of the real world. We accomplish this by
introducing the concept of a context-aware light source. This light source
provides illumination based on scene context in real-time. This allows us to
project feature enhancement in-place onto an object while it is being
manipulated by the user. A separate proxy light source can be employed to
enable freely programmable shading responses for interactive scene analysis. We
created a prototype hardware setup and have implemented several applications
that demonstrate the approach, such as a sharpening light, an edge highlighting
light, an accumulation light, and a light with a programmable, nonlinear
shading response.
