Resizing beyond widgets: object resizing techniques for immersive virtual environments

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 Pointer Orientation-based Resize Technique (PORT) and the Gaze-Hand resize technique take advantage of the user's proprioceptive cues and their spatial knowledge of the environment. We present these techniques as an alternative to 3D widgets and perform 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.
