Using Socially Expressive Mixed Reality Arms for Enhancing Low-Expressivity Robots
Expressivity--the use of multiple modalities to convey internal state and
intent of a robot--is critical for interaction. Yet, due to cost, safety, and
other constraints, many robots lack high degrees of physical expressivity. This
paper explores using mixed reality to enhance a robot with limited expressivity
by adding virtual arms that extend the robot's expressiveness. The arms,
capable of a range of non-physically-constrained gestures, were evaluated in a
between-subject study () where participants engaged in a mixed reality
mathematics task with a socially assistive robot. The study results indicate
that the virtual arms added a higher degree of perceived emotion, helpfulness,
and physical presence to the robot. Users who reported a higher perceived
physical presence also found the robot to have a higher degree of social
presence, ease of use, usefulness, and had a positive attitude toward using the
robot with mixed reality. The results also demonstrate the users' ability to
distinguish the virtual gestures' valence and intent.Comment: 8 pages, 9 figures, 3 tables, In 2019 IEEE International Symposium on
