我们提出了一种技术，结合虚拟增强的视觉效果与直观的互动的真实的世界。我们通过引入上下文感知光源的概念来实现这一点。该光源基于场景上下文实时提供照明。这使我们能够在用户操作对象时将功能增强就地投影到对象上。可以采用单独的代理光源来实现交互式场景分析的自由可编程着色响应。我们创建了一个原型硬件设置，并实现了几个演示该方法的应用程序，如锐化灯，边缘高亮灯，聚光灯和具有可编程非线性着色响应的灯。
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.
