Robots Have Been Seen and Not Heard: Effects of Consequential Sounds on Human-Perception of Robots

TL;DR

This study investigates how robot-produced sounds influence human perceptions, revealing that consequential sounds lead to more negative attitudes and feelings of distraction, impacting human-robot interaction quality.

Contribution

The paper provides empirical evidence on the negative impact of consequential sounds on human perceptions of robots in real-world settings.

Findings

Consequential sounds increase negative perceptions of robots.

Participants felt more distracted with consequential sounds.

Negative attitudes towards robots were significantly higher with sounds.

Abstract

Robots make compulsory machine sounds, known as `consequential sounds', as they move and operate. As robots become more prevalent in workplaces, homes and public spaces, understanding how sounds produced by robots affect human-perceptions of these robots is becoming increasingly important to creating positive human robot interactions (HRI). This paper presents the results from 182 participants (858 trials) investigating how human-perception of robots is changed by consequential sounds. In a between-participants study, participants in the sound condition were shown 5 videos of different robots and asked their opinions on the robots and the sounds they made. This was compared to participants in the control condition who viewed silent videos. Consequential sounds correlated with significantly more negative perceptions of robots, including increased negative `associated affects', feeling more distracted, and being less willing to colocate in a shared environment with robots.
