ABSTRACT
The most common technique for resizing 3D objects in virtual environments is the use of 3D widgets. However, such techniques often exhibit usability problems due to difficulties in selecting and manipulating the widgets. We have developed two novel interaction techniques for resizing objects in immersive VEs. Our two techniques, the Pointer Orientation-based Resize Technique (PORT) and the Gaze-Hand resize technique, take advantage of the user's proprioceptive sense and their spatial knowledge of the environment. We designed these techniques as an alternative to 3D widgets and performed a usability study to compare the effectiveness of all three techniques. Our results show that participants were able to perform tasks significantly faster with the two new techniques than with the existing 3D Widgets technique.
