A wide range of human–robot collaborative applications in diverse domains, such as
manufacturing, health care, the entertainment industry, and social interactions, require an …

Compact multi-sensor platforms are portable and thus desirable for robotics and personal-
assistance tasks. However, compared to physically distributed sensors, the size of these …

The paper describes progress achieved in our long-term research project ShopBot, which
aims at the development of an intelligent and interactive mobile shopping assistant for …

The problem of tracking multiple moving speakers in indoor environments has received
much attention. Earlier techniques were based purely on a single modality, eg, vision …

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 …

In this paper, we propose a novel method which is able to detect and separate audiovisual
sources present in a scene. Our method exploits the correlation between the video signal …

One of the most important abilities that personal robots need when interacting with humans
is the ability to discriminate amongst them. In this paper, we carry out an in-depth study of …

Any service robot should possess some kind of human–robot interaction to communicate
with users. In this paper we present a tour-guide robot able to recognize hand gestures and …

In this paper we present a study of vision-based, human-recognition solutions in human-
oriented, mobile-robot applications. Human recognition is composed of detection, tracking …

We propose an audio-visual fusion algorithm for 3D speaker tracking from a localised multi-
modal sensor platform composed of a camera and a small microphone array. After extracting …
