In biological vision systems the attention mechanism is responsible for selecting the relevant information from the sensed field of view. In robotics this ability is specially useful because of the restrictions in computational resources which are necessary to simultaneously perform different tasks. An emerging area in robotics is developing social robots which are capable to navigate and to interact with humans and with their environment by perceiving the real world in a similar way that people do. In this proposal we focus on the development of an object-based attention mechanism for a social robot. It consists of three main modules. The first one preattentive stage implements a concept of saliency based on proto-objects. In the second stage semiattentive significant items according to the tasks to accomplish are identified and tracked. Finally the attentive stage fixes the field of attention to the most salient object depending on the current task. 1. Introduction In the last few years emphasis has increased in the development of robot vision systems according to the model of natural vision due to its .
