zPots : A Virtual Pottery Experience Through Spatial Interactions Using the Leap Motion Device
Proceedings of the ACM CHI' 14 Extended Abstracts on Human Factors in Computing System (CHI EA'14) April 26- May 1, Toronto, Canada.

We present zPots, an application for gesture-free hand-based design of virtual pottery enabled by the Leap Motion device. With zPots, a user can shape and color 3D pots by moving bare hands in the air with minimal or no training. Unlike large-space hand-and-body movements required by depth cameras such as the Kinect, the use of the Leap motion device facilitates close range 3D interactions collocated with the personal computer. We demonstrate our application as a synergistic combination of novel spatial interactions and tool metaphors that cater to engaging and realistic experiences while supporting creativity in 3D shape conceptualization and modeling.
