The study presented in this paper explored people's perceptions and attitudes towards the idea of a future robot companion for the home. A human-centred approach was adopted using questionnaires and human-robot interaction trials to derive data from 28 adults. Results indicated that a large proportion of participants were in favour of a robot companion and(More)
This paper presents the combined results of two studies that investigated how a robot should best approach and place itself relative to a seated human subject. Two live Human Robot Interaction (HRI) trials were performed involving a robot fetching an object that the human had requested, using different approach directions. Results of the trials indicated(More)

Abstract – In the present study we investigated humanrobot and robot-human approach distances. We found that(More)
This articleii presents the results of video-based Human Robot Interaction (HRI) trials which investigated people’s perceptions of different robot appearances and associated attention-seeking features and behaviors displayed by robots with different appearance and behaviors. The HRI trials studied the participants’ preferences for various features of robot(More)
An empirical framework for Human-Robot (HR) proxemics is proposed which shows how the measurement and control of interpersonal distances between a human and a robot can be potentially used by the robot to interpret, predict and manipulate proxemic behaviour for Human-Robot Interactions (HRIs). The proxemic framework provides for incorporation of(More)
This paper presents results, outcomes and conclusions from a series of Human Robot Interaction (HRI) trials which investigated how a robot should approach a human in a fetch and carry task. Two pilot trials were carried out, aiding the development of a main HRI trial with four different approach contexts under controlled experimental conditions. The(More)
This paper presents results of a pilot study that investigated whether people’s perceptions from live and video HRI trials were comparable. Subjects participated in a live HRI trial and videotaped HRI trials in which the scenario for both trials was identical, and involved a robot fetching an object using different approach directions. Results of the trials(More)

This paper presents and discusses a longitudinal study which investigated habituation effects between humans and robots over a period of five weeks. Participants' preferences for the robot's approach distance with respect to its approach direction and appearance were investigated in a variety of domestic scenarios. These human-robot interaction (HRI)(More)
Outcomes are presented from experiments on the effect of participants' individual preferences for robot appearance and height on their preferences towards and perceptions of live robots. Participants who expressed a preference for a mechanical looking robot, tended to prefer all robot types to stay further away than those participants who expressed a(More)
