Voodoo dolls： seamless interaction at multiple scales in virtual environments

The content in the context of CGUI Lab Research (FMRG) 2024~ is quite close to a classic one. Or was it this short?

• The Voodoo Dolls technique is a method of interacting with objects from a distance in virtual reality environments. This technique overcomes some limitations of existing methods by offering a simple way to interact with objects of various sizes and allowing selection and manipulation of a wider range of objects.

• In the Voodoo Dolls technique, users create temporary copies of objects called “dolls” that can be manipulated by the hand holding them. For the sake of simplicity, it is assumed that the user is right-handed in the following discussion.

• By moving a doll held in the right hand relative to a doll in the 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. The user’s actions with the dolls are interpreted based on relative coordinates.

• The system scales the dolls so that the left-hand doll is half a meter in its longest dimension, while maintaining the relative sizes of other dolls. This feature enables users to seamlessly work at different scales.

• Additionally, the Voodoo Dolls technique allows users to select both visible and hidden objects, and provides a fixed reference point for working with moving objects, which is not typically possible in regular environments.
