VLEGO: a simple two-handed modeling environment based on toy blocks

Published: 01 July 1996 Publication History

Abstract

This paper describes a case study of building a prototype of an immersive three dimensional (3-D) modeler which supports simple two-handed operations. Designing 3-D objects in a virtual environment has a number of advantages for 3-D geometry creation over designing with traditional computer aided design (CAD) tools. In order to enhance the human-computer interaction in a virtual workspace, two-handed spatial input has been incorporated into a few 3-D designing applications. However, existing 3-D designing tools do not utilize two handed interaction for enhancing the interface sufficiently. Our prototype immersive modeler, VLEGO, employs some features of toy blocks to give flexible two-handed interaction for 3-D design. Features of VLEGO can be summarized as follows: Firstly, VLEGO supports various two-handed operations and hence it makes design environment intuitive and efficient. Secondly, possible location and orientation of primitives are discretely limited so that the user can arrange objects accurately with ease. Finally, the system automatically avoids collisions among primitives and adjusts their positions. As a result, precise design of 3-D objects can be achieved easily by using a set of two-handed operations in intuitive way. This paper describes the design and implementation of VLEGO as well as an experiment for examining the effectiveness of two-handed interaction.
