Robots operating in the presence of humans should adapt their plans and behavior accordingly. The recent area of human-aware planning (HAP) addresses this problem. In this paper, we propose a method for extending HAP to so-called Socially Aware planning. We build on known principles for human context recognition, extending them to support different social situations. In this new paradigm, we are able to define social norms and rules which are taken into account by the planning mechanism to obtain plans consisting of socially adjusted behaviors.
