Social networks become increasingly important in today‘s society. Until now, human interaction with these networks has been restricted to the use of two-dimensional input devices, such as keyboard, mouse, or touch screens on smartphones. Till this day, there are no standardized input methods and interaction design patterns for body-controlled human-computer-interaction. The intention of this thesis is to prove the feasibility of a three-dimensional body-controlled social network on the basis of a natural user interface (NUI). The NUI should provide the user a natural user experience and fulfill this requirements and needs. The NUI has been developed specifically for body-controlled interaction techniques. To prove the feasibility of the concept, an interactive prototype has been engineered and illustrated with a proof-of-concept video.
