Voodoo dolls： seamless interaction at multiple scales in virtual environments

The content related to the CGUI Lab Research (FMRG) context is quite similar to the classic one. Was it this short?

• The Voodoo Dolls technique is an interaction method used in immersive virtual environments to manipulate objects from a distance.
• This technique overcomes some limitations of existing methods by offering a simple way to interact with objects of various sizes and enabling the selection and manipulation of a wider range of objects.
  • Here, “lightweight” refers to the ease of interaction.
• In the Voodoo Dolls technique, users create temporary copies of objects, called dolls, which mimic the movements of the user’s hands holding them. For the sake of simplicity, it is assumed that the user is right-handed in the discussion that follows.
  • Creating copies.
• When a user holds a doll in their right hand and moves it in relation to a doll in their left hand, the object represented by the right-hand doll moves to the same position and orientation relative to the object represented by the left-hand doll.
  • If a user is holding a doll, movements of the opposite hand are interpreted as relative coordinates of the doll.
• The system adjusts the size of the dolls so that the left-hand doll is half a meter long along its longest dimension, while the other dolls maintain the same relative size. This feature allows users to seamlessly work at different scales.
  • Working across multiple scales is interesting.
• The Voodoo Dolls technique enables the selection of both visible and hidden objects and provides a fixed reference frame for working with objects in motion.
  • This is something that cannot be done in a typical environment.
