Five interaction techniques were designed and evaluated considering different aspects of domain requirements and human limitations. We demonstrated their effectiveness of designed techniques in two usability studies. The results suggested that no single technique is best for all task conditions. Techniques designed for cloning improved the domain task performance profoundly. The work suggests a further direction: passing domain knowledge to the design process to increase the usefulness of VEs.application/pdfenIn CopyrightVirtual environmentsTechnical reportTR-05-16http://eprints.cs.vt.edu/archive/00000727/01/cloning-2005.pdf
