The notion of ‘Smart Artifacts’ describes technology-enhanced everyday objects, which are equipped with sensors, memory and communication capabilities (see, e.g., Ferguson, 2003 or Gellersen et al., 2000). Hence, they are able to capture information about their surrounding, communicate with each other and react according to previously defined rules (Schoch and Strassner, 2003). Through the capability to interact with humans directly, they can help users to accomplish their tasks in new, intuitive ways (Bohn et al., 2004; 2005). The terms ‘Smart Objects’ and ‘Intelligent Objects’ are synonymously used and describe the same underlying concepts.

Abstract
In this chapter we present a novel concept for personalized privacy support on large public displays. In the first step, two formative evaluations are conducted in order to analyze the requirements of potential users regarding the protection of private information on large public displays. The insights gained in these evaluations are used to design a system that automatically adapts the information visible on public displays according to the current social situation and the individual privacy preferences of the user working on the display. In a third evaluation, the developed system is evaluated regarding its appropriateness for daily usage and its usefulness to protect privacy. The results of the evaluation show that users are in general willing to trust system-based protection mechanisms, provided that they are well implemented. In this context, the proposed combination of pre-defined privacy profiles and context-adapted information visualization proved to be a good trade-off between usability and adequate privacy protection.
