For human–robot interaction (HRI), perception is one of the most important capabilities. This
paper reviews several widely used perception methods of HRI in social robots. Specifically …

This paper gives an overview of the research papers published in Symbol Grounding in the
period from the beginning of the 21st century up 2012. The focus is in the use of symbol …

One of fundamental issues for service robots is human–robot interaction. In order to perform
such a task and provide the desired services, these robots need to detect and track people …

Anchoring is the problem of connecting, inside an artificial system, symbols and sensor data
that refer to the same physical objects in the external world. This problem needs to be solved …

This paper proposes a tracking system called VooDoo for 3D tracking of human body
movements based on a 3D body model and the iterative closest point (ICP) algorithm. The …

In this paper we describe a system that enables a mobile robot equipped with a color vision
system to track humans in indoor environments. We developed a method for tracking …

Head pose and gesture offer several key conversational grounding cues and are used
extensively in face-to-face interaction among people. We investigate how dialog context …

Our work evaluates a mobile robot's ability to communicate intended movements to humans
via projection of visual arrows and a simplified map. Humans utilize a variety of techniques …

In order to enable the widespread use of robots in home and office environments, systems
with natural interaction capabilities have to be developed. A prerequisite for natural …

In the recent past, service robots that are able to interact with humans in a natural way have
become increasingly popular. A special kind of service robots that are designed for personal …
