Direct 3D Manipulation Using Vision-Based Recognition of Uninstrumented Hands

Sinisa KolaricAlberto RaposoMarcelo Gattass

We describe a prototype of an interactive Mixed Reality application for direct spatial manipulation, based on the vision-based recognition of uninstrumented hands. In our application, we dynamically integrate both of the user's hands into the virtual environment, effectively creating a logical 2 × 3 DoF manipulation device. Using this logical device, we were able to implement, in conjuction with hand gestures, a number of fundamental 3D manipulation operations like select, deselect, translate, rotate, and scale.
