research
Gaze-Based Robot Failure Detection
This line of work investigates the relationship between human gaze behaviour and robot failures. Using robot-assisted collaborative tasks (such as tangram puzzles), I explore how different failure types affect human perception and gaze dynamics, presenting gaze as a potential signal for robot error detection and recovery.Overview
Trust Dynamics Across Multiple Robot Failures
This study explores the dynamics of trust in human-robot collaboration in the context of repeated robot failures. It focuses on how the consistency of failure types and the robot's awareness of its own errors affect user perceptions of trust and intelligence.Overview
