Human tracking based on attention distraction

The face tracker system of a humanoid, ISAC (Intelligent Soft Arm Control), is integrated with two modalities for localizing humans in order to direct ISAC´s attention and to prevent ISAC from being quickly distracted. The sound source localization and passive infrared (PIR) motion detection systems are used to provide the face tracker system with candidate regions for finding a face. However, the sensing modules should not directly gain control of the tracking if the system has recently acquired a new face. Our goal is to allow a human to redirect the attention of the system, but give the system a method to ignore the distraction if recently engaged
