Drawing, Painting, and Sculpting in the Air: Development Studies about an Immersive Free-Hand Interface for Artists

The main problems in immersive free-hand interfaces for artists are devices and methods to reach the level of fine motor skills in the human artistic capacity. The artist needs more solutions to flexibly master how the hand traces are left in the graphics. Leaving traces in immersion should not be only an action of controlling the route, but controlling also a variable outlook of the becoming line. For instance, as stretching the mouth of a tube, wherefrom fresh clay comes out when drawing it thru the air. This involves innovations about both drawing device and the handling of graphical primitives. We present our idea of a low prize palm-attachable device ‘Näprä’, a natural 3d finger tip control for elastic drawing profiles, and ideas about shaping both triangle meshes and particle clouds with it.
