Implementation and Evaluation of a See-through the lens Interface in an Immersive Virtual Environment

摘要

Interaction in an immersive virtual environment is still limited by several factors such as imperfect depth cues and instable hand placement in midair. In this article, we summarize the design and implementation of a See-through the lens interface within an immersive environment using a handheld device such as a PDA or a UMPC. Our interface tries to alleviate the abovementioned problems by simplifying the selection and manipulation processes using image based interaction techniques. An empirical study shows the effectiveness of the proposed interface for selecting 3D objects, especially when the target is small or in motion.
