The bachelor thesis „Implementation of a modular developing environment for extending sensory and actory features to a knob“ was written as part of the research project „potentials of ambient communication environments“. (Reviewed by Prof. Hannes Nehls and Prof. Dr. Clemens Westerkamp) The goal of this thesis was to explore and shape awareness for ambient interactions for common input devices. One of this devices which is often used in different types of products in our daily use is the knob/ rotary encoder. It was identified that the knob as an input device has a potential for extending itself with ambient communication interactions. Different ambient technologies to achieve this were explored and classified.
