Grounding Mindfulness in Embodied Tangibles: A Scoping Review & Theoretical Framework for HCI Design
Tharaka Sachintha Ratnayake, Samangi Wadinambiarachchi, Sarah Schömbs +3
Embodied and tangible devices are increasingly used to support mindfulness practices across meditation, yoga, and everyday routines. However, existing HCI research lacks a coherent…
HoRD: Robust Humanoid Control via History-Conditioned Reinforcement Learning and Online Distillation
Puyue Wang, Jiawei Hu, Yan Gao +7
Humanoid robots can suffer significant performance drops under small changes in dynamics, task specifications, or environment setup. We propose HoRD, a two-stage learning framework…
Modelling Visuo-Haptic Perception Change in Size Estimation Tasks
Jian Zhang, Wafa Johal, Jarrod Knibbe
Tangible interactions involve multiple sensory cues, enabling the accurate perception of object properties, such as size. Research has shown, however, that if we decouple these cue…
From Conversation to Orchestration: HCI Challenges and Opportunities in Interactive Multi-Agentic Systems
Sarah Schömbs, Yan Zhang, Jorge Goncalves +1
Recent advances in multi-agentic systems (e.g. AutoGen, OpenAI Swarm) allow users to interact with a group of specialised AI agents rather than a single general-purpose agent. Desp…
Going Down the Abstraction Stream with Augmented Reality and Tangible Robots: the Case of Vector Instruction
Sergei Volodin, Hala Khodr, Pierre Dillenbourg +1
Despite being used in many engineering and scientific areas such as physics and mathematics and often taught in high school, graphical vector addition turns out to be a topic prone…
Illusion Spaces in VR: The Interplay Between Size and Taper Angle Perception in Grasping
Jian Zhang, Wafa Johal, Jarrod Knibbe
Leveraging the integration of visual and proprioceptive cues, research has uncovered various perception thresholds in VR that can be exploited to support haptic feedback for graspi…
Real-Time Detection of Robot Failures Using Gaze Dynamics in Collaborative Tasks
Ramtin Tabatabaei, Vassilis Kostakos, Wafa Johal
Detecting robot failures during collaborative tasks is crucial for maintaining trust in human-robot interactions. This study investigates user gaze behaviour as an indicator of rob…
Gazing at Failure: Investigating Human Gaze in Response to Robot Failure in Collaborative Tasks
Ramtin Tabatabaei, Vassilis Kostakos, Wafa Johal
Robots are prone to making errors, which can negatively impact their credibility as teammates during collaborative tasks with human users. Detecting and recovering from these failu…
Can you pass that tool?: Implications of Indirect Speech in Physical Human-Robot Collaboration
Yan Zhang, Tharaka Sachintha Ratnayake, Cherie Sew +3
Indirect speech acts (ISAs) are a natural pragmatic feature of human communication, allowing requests to be conveyed implicitly while maintaining subtlety and flexibility. Although…
ROSAnnotator: A Web Application for ROSBag Data Analysis in Human-Robot Interaction
Yan Zhang, Haoqi Li, Ramtin Tabatabaei +1
Human-robot interaction (HRI) is an interdisciplinary field that utilises both quantitative and qualitative methods. While ROSBags, a file format within the Robot Operating System…
Assisting MoCap-Based Teleoperation of Robot Arm using Augmented Reality Visualisations
Qiushi Zhou, Antony Chacon, Jiahe Pan +1
Teleoperating a robot arm involves the human operator positioning the robot's end-effector or programming each joint. Whereas humans can control their own arms easily by integratin…
OfficeMate: Pilot Evaluation of an Office Assistant Robot
Jiahe Pan, Sarah Schömbs, Yan Zhang +3
Office Assistant Robots (OARs) offer a promising solution to proactively provide in-situ support to enhance employee well-being and productivity in office spaces. We introduce Offi…
Using Fitts' Law to Benchmark Assisted Human-Robot Performance
Jiahe Pan, Jonathan Eden, Denny Oetomo +1
Shared control systems aim to combine human and robot abilities to improve task performance. However, achieving optimal performance requires that the robot's level of assistance ad…
