We study to which extent Leap Motion can be used for midair interaction while working on various virtual assembling and shape modeling tasks. First, we outline the conceptual design phase, which is done by studying and classification of how human hands are used for various creative tasks in real life. Then, during the phase of the functional design, we propose our hypothesis how to efficiently implement and use natural gestures with Leap Motion and introduce the ideas of the algorithms. Next we describe the implementation phase of the gestures in virtual environment. It is followed by the user study proving our concept.
