More other notes about SARs

  • How a robot speaks to a user affects that user’s experience with the robot. When a robot calls a person by name, that individual is more likely to rate the robot as friendlier and behave in a more socially engaged way (e.g. pay closer attention and speak more to the robot).
  • People tend to respond more positively to robots that appear more animated and that demonstrate emotional responses (e.g. appropriate facial expressions and animated verbal content) during an interaction.
  • User personality traits and the “match” between user personality and robot style is another factor that might facilitate human-robot engagement.
  • A match between user personality and robot “personality” (e.g., content of feedback and style of feedback) is associated with increased time spent with the robot.
  • It’s important to acknowledge that users generally respond quite positively to robots across a wide range of design forms. This isn’t to say that all users (e.g., from different cultures and with different experience levels) react to robots in the exact same manner.
  • Variability exists and has been documented in how people view and respond to robots.
  • Users across the lifespan tend to be quite open to interactions with robots.
    Children and young people tend to react positively to robots, readily engaging in play activities with them.
  • Older adults and the elderly frequently report being willing to accept assistance from robots in a variety of tasks, including household activities and medication reminders.
  • Additional experience and time interacting with robots seems to foster even more positive reactions.
  • Even over short periods of time (e.g. weeks), users who repeatedly interact with a robot appear to become more comfortable and change their behaviour with the robot accordingly (e.g. increased physical closeness to the robot) to reflect their increasing comfort level.
