Why did I chose Social Robotics?

You’re Number 2



Understanding HumansSometimes it’s difficult to

understand and live with others

You’re Number 3



Understanding RobotsSo what about living with robots?

You’re Number 4


Social Robotics – Semester Project – Introduction to Robotics You’re Number 5



What is a social robot?Robots that people apply a social model to in

order to interact with and to understand

A question:“Does the robot only appear to be socially

intelligent or is it genuinely so?”

You’re Number 6



Social ModelsConstrained Full

You’re Number 7



Robotic Social DevelopmentLeverage from playful, infant like interaction to foster its social Development

Kismet

You’re Number 8



What it should look like?

Dogs are socially Responsive and socially intelligent in a genuine sense

Robot doesn’t have to look like a humanTo be genuinely social intelligent

You’re Number 9



Social Robot Success

What matters is how the robot interacts face to facewith people, and how peopleinteract with it in a human environment

You’re Number 10



Known TypesEncourage people to anthropomorphize the technology in orderTo interact with it (but goes no further)

Uses human-like social cues and communication modalitiesTo facilitate interactions with humans, the social model Tends to be shallow and its social behavior is pre-canned.

Benefit from interaction with people (training model). TheseInteractions their internal structure in a deeper level. People Shape the robot’s behavior. They are socially passive.

Socially participative with their own internal goals and Motivations. Engage people in a social manner to benefitBoth the person and the robot. The robot’s social behavior Stems from its computational social psychology.

Speaking Turns

The ability to exchange turns during face-to-face interactions is the cornerstone of human style

communication and instruction

You’re Number 14



Speaking turns Limitations

Respond After 0.1 sec




You’re Number 15



Envelope Displays

Regulating Speaking turns

Facial Displays

gestures

Shifts in gaze

Eye blinks

Eye contact

Raise of eyebrows

Paralinguistic Social Cues

You’re Number 16



Experiments

You’re Number 17



Kismet’s Envelope Displays

You’re Number 18

No. Action Cue

1 Acquire the Floor Break eye contactLean back

2 Start a speaking turn Vocalize a Kismet-esque babble

3 Stop a speaking turn Stop vocalization and re-establish eye contact

4 Hold the floor Look to the side

5 Relinquish the floor Raise browsLean forward a bit

Blinking occurs at most at the end of vocalization.



Social Robot Evaluation• Do People intuitively read and naturally respond to

Kismet’s social cues?• Can Kismet perceive and appropriately respond to

theses naturally offered cues?• Does the human adapt to the robot and the robot

adapt to the human, in a way that benefits the interaction

• Specifically, is the resulting interaction natural, intuitive and enjoyable for the human

• Can Kismet perform well despite its perceptual, mechanical, behavioral and computational limitations?
