From Gesture to Form: The Evolution of Expressive Freehand Spatial Interfaces

Article PDF (743.79 KB)

This paper presents a series of insights from an ongoing investigation into refining custom spatial computer interfaces and graphical primitives for suggesting 3D form in immersive digital spaces. Technical innovations utilizing 3D gesture capture, force feedback, and stereoscopic presentation are described through reference to specific free-form digital sculptures created with the CavePainting and Drawing on Air interfaces. The role of the human hand in digital art practice and the potential of interfaces that tightly couple freehand movements with geometric algorithms are discussed.
