Interaction between humans involves a plethora of sensory information, both in the form of explicit communication as well as more subtle unconsciously perceived signals. In order to enable natural human-robot interaction, robots will have to acquire the skills to detect and meaningfully integrate information from multiple modalities. In this article, we focus on sound localization in the context of a multi-sensory humanoid robot that combines audio and video information to yield natural and intuitive responses to human behavior, such as directed eye-head movements towards natural stimuli. We highlight four common sound source localization algorithms and compare their performance and advantages for real-time interaction.     «
