Prosody for Intuitive Robotic Interface Design: It's Not What You Said, It's How You Said It
arxiv(2024)
摘要
In this paper, we investigate the use of 'prosody' (the musical elements of
speech) as a communicative signal for intuitive human-robot interaction
interfaces. Our approach, rooted in Research through Design (RtD), examines the
application of prosody in directing a quadruped robot navigation. We involved
ten team members in an experiment to command a robot through an obstacle course
using natural interaction. A human operator, serving as the robot's sensory and
processing proxy, translated human communication into a basic set of navigation
commands, effectively simulating an intuitive interface. During our analysis of
interaction videos, when lexical and visual cues proved insufficient for
accurate command interpretation, we turned to non-verbal auditory cues.
Qualitative evidence suggests that participants intuitively relied on prosody
to control robot navigation. We highlight specific distinct prosodic constructs
that emerged from this preliminary exploration and discuss their pragmatic
functions. This work contributes a discussion on the broader potential of
prosody as a multifunctional communicative signal for designing future
intuitive robotic interfaces, enabling lifelong learning and personalization in
human-robot interaction.
