It is described the integration of user tracking data into a WFS system and the use of such data to simulate directive focused and distant sources in combination with a room simulation based on measured room impulse responses. Section 2 reviews the derivation of the operator used to calculate the loudspeaker signals. In section 3 the single-useroptimization of the operator is described. A short listening experiment to verify the results is presented in section 4. Section 5 gives an extension to a multiuser-scenario. In section 6 the integration of a room simulation into this framework is presented. The paper ends with a conclusion in section 7.
