Abstract: A system (120) and/or corresponding method introduces a minor change to a given set of parameters (110) that affect an ambiance (130) associated with an environment, and collects the user's response to the change. Based on the user's response, the system learns which changes to which parameters lead to an improved effect. By repeating the change-feedback sessions, the system approaches an optimal setting for achieving the desired ambiance in the given environment. Preferably, the change-feedback session is non-obtrusive, and occurs, for example, each time a light is turned on, and the feedback is collected when the light is turned off, using a multiple switch arrangement. If the light is turned off using one switch, the feedback is positive; if the light is turned off using an alternative switch, the feedback is negative. Alternatively, the system can be placed in a rapid-learning mode, wherein the change-feedback cycles occur more frequently.
