Assistive robots can support activities of elderly people to uplift the living standard. The assistive robots should possess the ability to interact with the human peers in a human friendly manner because those systems are intended to be used by non-experts. Humans prefer to use voice instructions that include uncertain information and lexical symbols.(More)
A vast range of human-friendly interactive robotics heads are developed by researchers. However, the interactive robot heads require improvements in construction and behavior to achieve more human-like interaction. Therefore this paper proposes a design of an interactive robotic head with human-like movements and human-friendly interactive features. The(More)
Service robots are being developed as a supportive aid for elderly people. Those robots are operated by non-expert users in heterogeneous domestic environments. Hence, the ability of a robot to be operated in a more natural human friendly manner enhances the overall satisfaction of the user. Humans prefer to use voice in order to convey instructions. Those(More)
This paper proposes a method for adapting robot's perception to produce fuzzy vocal responses about the size of an object based on the visual attention of the robot. In a human-human interaction, the humans may use vocal responses, which have qualitative terms such as "small", "large" etc. The actual quantitative meaning of those terms depends on spatial(More)
The Human shows a remarkable capability in localizing a sound source and navigating towards it. In the current context of robotic applications, machinery models have been developed, so that they can be used in sound source localization. But, it is not yet quantified the accuracy of human's sound source localization in different frequencies and distances at(More)
