| The desire to have intuitive, seamless 3D interaction fuels research into new 3D interaction approaches. However, research continues to rely on Brunelleschi's perspective to provide a sense of visual depth to create a 3D graphical display. The interactive control space has been mapped directly into the 3D virtual display space without much thought about the effect that perspective distortion has on the interaction.;There are a myriad of possible 3D control-display mappings. Previously, 3D interaction mapping options have focused on the manipulation of control-display ratio. In this thesis, I present a conceptual framework that provides a more general control-display description.;I conduct a user study to compare three different mappings to the commonly used mapping for 3D selection and manipulation tasks. The results indicate that all three may be considered viable alternatives. Together, this 3D control-display mapping framework and study open the door to further exploration of 3D interaction variations. |
