Abstract
Gesture-based 3D interaction has been considered a relevant research topic as it has a natural application in several scenarios. Yet, it presents several challenges due to its novelty and consequential lack of systematic development methodologies, as well as to inherent usability related problems. Moreover, it is not always obvious which are the most adequate and intuitive gestures, and users may use a variety of different gestures to perform similar actions. This chapter describes how spatial freehand gesture based navigation methods were developed to be used in virtual walkthroughs meant to be experienced in large displays using a depth sensor for gesture tracking. Several iterations of design, implementation, user tests, and controlled experiments performed as formative and summative evaluation to improve, validate, and compare the methods are presented and discussed.
