Walk Along: An Experiment on Controlling the Mobile Robot ‘Spot’ with Voice and Gestures

ACM Transactions on Human-Robot Interaction, Journal Year: 2025, Volume and Issue: unknown

Published: April 12, 2025

Robots are becoming more capable and can autonomously perform tasks such as navigating between locations. However, human oversight remains crucial. This study compared two touchless methods for directing mobile robots: voice control gesture control, to investigate the efficiency of these preference users. We tested in conditions: one which participants remained stationary they walked freely alongside robot. hypothesized that walking robot would result higher intuitiveness ratings improved task performance, based on idea promotes spatial alignment reduces effort required mental rotation. In a 2×2 within-subject design, 218 guided quadruped Spot along circuitous route with multiple 90° turns using rotate left, right, walk forward commands. After each trial, rated command mapping, while post-experiment interviews were used gather participants’ preferences. Results showed combined was most favored intuitive, whereas standing caused confusion left/right Nevertheless, 29% preferred citing increased engagement visual congruence reasons. An odometry-based analysis revealed often followed behind Spot, particularly condition, when allowed walk. conclusion, produced best outcomes.
