Amirabdollahian, Farshid; Op Den Akker, R.; Bedaf, S.; Bormann, R.; Draper, H.; Evers, V.; Gallego Perez, J.; Gelderblom, Gert Jan; Ruiz, C.G.; Hewson, D.; Hu, N.; Koay, Kheng; Lehmann, Hagen; Marti, P.; Michel, H.; Prevot-Huille, H.; Reiser, U.; Saunders, Joe; Sorell, T.; Stienstra, Jelle; Syrdal, D.S.; Walters, Michael; Dautenhahn, K. (2013-12)A new stream of research and development responds to changes in life expectancy across the world. It includes technologies which enhance well-being of individuals, specifically for older people. The ACCOMPANY project focuses ... -
Classification of Personal Data Used by Personalised Robot Companions Based on Concern of Exposure
Riches, Lewis; Koay, Kheng; Holthaus, Patrick (Springer Nature Link, 2023-02-02)We present a paper looking at the accidental exposure of personal data by personalised companion robots in human-robot interaction. Due to the need for personal data, personalisation brings inherent risk of accidental ... -
Deep Learning for Condition Detection in Chest Radiographs: A Performance Comparison of Different Radiograph Views and Handling of Uncertain Labels
Ahmad, Mubashir; Koay, Kheng; Sun, Yi; Jayaram, Vijay; Arunachalam, Ganesh; Amirabdollahian, Farshid (2023-04-28)Chest radiographs are the initial diagnostic modality for lung or chest-related conditions. It is believed that radi- ologist’s availability is a bottleneck impacting patient’s safety because of long waiting times. With ... -
Differences of Human Perceptions of a Robot Moving using Linear or Slow in, Slow out Velocity Profiles When Performing a Cleaning Task
Schulz, Trenton; Holthaus, Patrick; Amirabdollahian, Farshid; Koay, Kheng; Torresen, Jim; Herstad, Jo (Institute of Electrical and Electronics Engineers (IEEE), 2019-10-14)We investigated how a robot moving with different velocity profiles affects a person's perception of it when working together on a task. The two profiles are the standard linear profile and a profile based on the animation ... -
Does Expression of Grounded Affect in a Hexapod Robot Elicit More Prosocial Responses?
Hickton, Luke; Lewis, Matthew; Koay, Kheng; Cañamero, Lola (EPSRC UK-RAS Network, 2020-05-07)We consider how non-humanoid robots can communicate their affective state via bodily forms of communication, and the extent to which this can influence human response. We propose a simple model of grounded affect and kinesic ... -
Evaluating people's perceptions of trust in a robot in a repeated interactions study
Rossi, Alessandra; Dautenhahn, Kerstin; Koay, Kheng; Walters, Michael; Holthaus, Patrick (2020-11-06)Trust has been established to be a key factor in fostering human-robot interactions. However, trust can change overtime according to different factors, including a breach of trust due to a robot’s error. In this exploratory ... -
Formal verification of an autonomous personal robotic assistant
Webster, M.; Dixon, C.; Fisher, M.; Salem, Maha; Saunders, Joe; Koay, Kheng; Dautenhahn, K. (AAAI, 2014-03)Human–robot teams are likely to be used in a variety of situations wherever humans require the assistance of robotic systems. Obvious examples include healthcare and manufacturing, in which people need the assistance of ... -
How does peoples’ perception of control depend on the criticality of a task performed by a robot Paladyn
Chanseau, Adeline; Dautenhahn, Kerstin; Koay, Kheng; Walters, Michael; Lakatos, Gabriella; Salem, Maha (2019-12-17)Robot companions are starting to become more common and people are becoming more familiar with devices such as Google Home, Alexa or Pepper,one must wonder what is the optimum way for people to control their devices? This ... -
In good company? : Perception of movement synchrony of a non-anthropomorphic robot
Lehmann, Hagen; Saez-Pons, Joan; Syrdal, D.S.; Dautenhahn, K.; Koay, Kheng (2015-05-22)Recent technological developments like cheap sensors and the decreasing costs of computational power have brought the possibility of robotic home companions within reach. In order to be accepted it is vital for these robots ... -
Integrating Constrained Experiments in Long-term Human-Robot Interaction using Task– and Scenario–based Prototyping
Syrdal, D.S.; Dautenhahn, K.; Koay, Kheng; Ho, Wan (2015-05-27)In order to investigate how the use of robots may impact everyday tasks, 12 participants interacted with a University of Hertfordshire Sunflower robot over a period of 8 weeks in the university’s Robot House.. Participants ... -
A Narrative Approach to Human-Robot Interaction Prototyping for Companion Robots
Koay, Kheng; Syrdal, Dag Sverre; Dautenhahn, Kerstin; Walters, Michael (2020-03-08)This paper presents a proof of concept prototype study for domestic home robot companions, using a narrative-based methodology based on the principles of immersive engagement and fictional enquiry, creating scenarios which ... -
Prototyping Realistic Long-Term Human-Robot Interaction for the Study of Agent Migration
Koay, Kheng; Syrdal, Dag Sverre; Dautenhahn, Kerstin (2016-08-26)This paper examines participants’ experiences of interacting with a robotic companion (agent) that has the ability to move its “mind” between different robotic embodiments to take advantage of the features and functionalities ... -
