Application and taxonomy of through-the-lens techniques
Stanislav L. Stoev, Dieter Schmalstieg · 2002
In this work, we present a set of tools based on the through-the-lens metaphor. This metaphor enables simultaneous exploration of a virtual world from two different viewpoints. The one is used to display the surrounding environment and represents the user, the other is interactively manipulated and the resulting images are displayed in a dedicated window. We discuss in detail the various different states of the two viewpoints and the two synthetic worlds, introducing taxonomy for their relationship to each other. We also elaborate on navigation with the through-the-lens concept extending the ideas behind known tools. Furthermore, we also present a new remote object manipulation technique based on the through-the-lens concept.
