Acceptance of Robots Depends on Social Presence
While it may sound like a sci-fi movie script, technological advances have created robots that can play an active role in everyday life.
A recent conference of international researchers discussed the role assignments of robots and how the presentation of the robot makes a difference in how the robot is accepted by end users.
For example, if you tickle a robot, it may not laugh, but you may still consider it humanlike, depending on its role in your life.
Designers and engineers assign robots specific roles, such as servant, caregiver, assistant or playmate. Researchers found that people expressed more positive feelings toward a robot that would take care of them than toward a robot that needed care.
“For robot designers, this means greater emphasis on role assignments to robots,” said S. Shyam Sundar, Ph.D. “How the robot is presented to users can send important signals to users about its helpfulness and intelligence, which can have consequences for how it is received by end users.”
To determine how human perception of a robot changed based on its role, researchers observed 60 interactions between college students and Nao, a social robot developed by Aldebaran Robotics, a French company specializing in humanoid robots.
Each interaction could go one of two ways. The human could help Nao calibrate its eyes, or Nao could examine the human’s eyes like a concerned eye doctor and make suggestions to improve vision.
Participants then filled out a questionnaire about their feelings toward Nao. Researchers used these answers to calculate the robot’s perceived benefit and social presence in both scenarios.
The results of this interaction are published in the journal Computers in Human Behavior.
“When (humans) perceive greater benefit from the robot, they are more satisfied in their relationship with it, and even trust it more,” said Sundar, who studies human-robot interaction at Penn State University. “In addition, we found that when the robot cares for you, it seems to have greater social presence.”
A robot with a strong social presence behaves and interacts like an authentic human, according to Ki Joon Kim, doctoral candidate in the department of interaction science, Sungkyunkwan University, Korea, and lead author of the journal article.
The research team found that when participants perceived a strong social presence, they considered the caregiving robot smarter than the robot in the alternate scenario. Participants were also more likely to attribute human qualities to the caregiving robot.
“Social presence is particularly important in human-robot interactions and areas of artificial intelligence because the ultimate goal of designing and interacting with social robots is to provide users with strong feelings of socialness,” said Kim.
The next immediate goal is to confirm these experimental findings in real-life situations where caretaker robots are already working. Examining how other robot roles influence human perception toward them is also important.
“We have just finished collecting data at a local retirement village in State College with the Homemate robot which we brought in from Korea,” said Sundar. “In that study, we are examining differences in user reactions to a robot that is an assistant versus one that is framed as a companion.”
