In graduate school, learning about how to build intelligent CAD interfaces greatly interested me. Around the same time, I was exposed to the Leap Motion Controller, a device that can use hand and finger positions as input. As part of a project in the Human in the Loop Systems Lab, I was inspired to make a CAD interface with which users can generate and interact with 3D models using native gestures instead of mouse and keyboard. I defined gestures, wrote the software in MATLAB to recognize the gestures, and programmed a CAD interface to allow input of those gestures to create and manipulate 3D models. This work resulted in a publication.
