In this paper, we present a novel method for object manipulation in immersive virtual environments. The proposed technique exploits a novel widget, called “Smart Pin”, to enable the user to select, translate, rotate and scale objects relying entirely on the positional tracking of a single hand. It is, therefore, suitable for several real-world applications where handheld devices are not available, the surrounding environmental conditions make orientation tracking hard, and the non-dominant hand may be involved in different tasks. We evaluated the method with users on two classical tasks such as detail search and docking, comparing it with a successful two-handed manipulation technique (Handlebar). The measured execution efficiency obtained with the two methods was similar, but most users preferred the Smart Pin for its gestural comfort and ease of use.

Abstract

In this paper, we present a novel method for object manipulation in immersive virtual environments. The proposed technique exploits a novel widget, called “Smart Pin”, to enable the user to select, translate, rotate and scale objects relying entirely on the positional tracking of a single hand. It is, therefore, suitable for several real-world applications where handheld devices are not available, the surrounding environmental conditions make orientation tracking hard, and the non-dominant hand may be involved in different tasks. We evaluated the method with users on two classical tasks such as detail search and docking, comparing it with a successful two-handed manipulation technique (Handlebar). The measured execution efficiency obtained with the two methods was similar, but most users preferred the Smart Pin for its gestural comfort and ease of use.
