Optical Sight Metaphor for Virtual Environments

Abstract

Optical sight is a new metaphor for selecting distant objects or precisely pointing at close objects in virtual environments. Optical sight combines ray-casting, hand based camera control, and variable zoom into one virtual instrument that can be easily implemented for a variety of virtual, mixed, and augmented reality systems. The optical sight can be modified into a wide family of tools for viewing and selecting objects. Optical sight scales well from desktop environments to fully immersive systems
