The Aesthetic of the Body Why is Aesthetic important? A.G. Billard, Autonomous Robots Class Spring 2007
The Aesthetic of the Body It is a truism that people will be more inclined to interact with “attractive” faces than with “unattractive” ones. Typical appealing features are large eyes, symmetric and round faces, pink cheeks and big eyelashes. Dolls’ faces versus Monster’s faces? A.G. Billard, Autonomous Robots Class Spring 2007 C.

The Aesthetic of the Body Repliee R1: Ishiguro’s lab, Osaka Univ. This android has 9 degree of freedom in her head. She can move her eyes, eyelids, mouth, and neck. Its body is covered with silicone, so the skin feels humanlike.And it has 4 high sensitivity skin sensors under the skin. A.G. Billard, Autonomous Robots Class Spring 2007
The Aesthetic of the Body Repliee R2: Ishiguro’s lab, Osaka Univ. Facial expressions of the adult android: 13 of the 42 actuators are used in the head. Humanlike facial expressions are realized by the motion of the eyes and mouth. A.G. Billard, Autonomous Robots Class Spring 2007
The Aesthetic of the Body Together with the company Kokoro, Ishiguro’s lab at Osaka Univ has developed a new life-like android called Actroid DER2.

Designing Robot’s Faces • Kaspar has 8DOF head and two 6DOF arms. • Rational behind the development of Kaspar is: • consistency of appearance and complexity between the head, body and hands to aid natural interaction • minimal expressive features to create the impression of sociability Mike Blow, Kerstin Dautenhahn, Andrew Appleby, Chrystopher L.

Expressive Body Movements Keepon (Kozima’s group, CRL, Japan): Very simple but powerful design to convey joint attention and turn taking behavior A.G. Billard, Autonomous Robots Class Spring 2007
Expressive Body Movements Keepon's kinematic mechanism. Two gimbals are connected by four wires; the lower gimbal is driven by two motors. Another motor rotates the whole inner-structure; yet another drives the skull downward for bobbing. A.G. Billard, Autonomous Robots Class Spring 2007
Expressive Body Movements Attentive action Directing the head up/down and left/right so as to orient Keepon's face/body to a certain target in the environment. Keepon seems to be perceiving the target. This action includes eye-contact and joint attention. Emotive action Keeping its attention in a certain direction, Keepon rocks its body from side to side and/or bobs its body up and down. Keepon seems to express emotions (like pleasure and excitement) about the target. A.G. Billard, Autonomous Robots Class Spring 2007
Designing Robot Toys Robota: Educational and Therapeutic Toy A.G. Billard, Autonomous Robots Class Spring 2007
What is the use of Robota? Robota, DIDEL SA Price: $2’800.- My Real Baby, IRobot Corp Price: $100.- SDR-3X, Sony Price: Luxury car (>$100’000.-) Robota fills a gap in the market: It is an affordable humanoid robot Teaching toy: It provides a nice basis for child-robot interaction Education: It has development software, you can have several robots in a class room
Designing Robot Toys Design Issues behind Robota • Robota’s Body: • Cuteness • Human-likeness, i.e. respecting the body proportion of a young child (between 16 and 20 months old), • Naturalness of the motions, i.e. the robot’s motions should be human-like. • Robota’s Capabilities: Provided with capabilities for interactions that a child of this age would display: • To recognize human faces and direct its gaze towards the user, • To understand and learn a restricted vocabulary • Simple imitation of the user’s motion A.G.

Body and Brain must Match • It is fundamental that the robot’s cognitive capabilities match its physical appearance. • An “adult-like” humanoid robot will be expected to produce adult-like capabilities (understanding of speech and complex manipulation capabilities). • Conversely, if one interacts with a baby-like robot, one will probably have lower expectations on the robot’s speech and manipulation capabilities. A.G. Billard, Autonomous Robots Class Spring 2007
Designing the body and the brain of a robot • Why are the key criteria? • The robot’s body creates expectations in terms of the robot’s capabilities. • If these do not match, the robot loses some of its believability and of its appeal. • What are the main challenges? • To manage to endow the robot with complex facial and body expressions, while not loosing the aesthetic of the robot. • To better understand the complex and subtle effects that each of these features have on human-robot interaction.

Human-like behavior Subject standing against a wall Subject seated on a chair 4 different scenarios were studied in the trials where a robot approached the subject who was located in the living room: 1) Seated on a chair in the middle of an open space. 2) Standing in the middle of an open space. 3) Seated at a table in the middle of an open space. 4) Standing with their back against a wall.

Human-like behavior • The main findings were: • Humans strongly did not like a direct frontal approach by a robot, especially while sitting (even at a table) or while standing with their back to a wall. • An approach from the front left or front right was preferred. • When standing in an open space a frontal approach was more • acceptable and although a rear approach was not usually most • preferred, it was generally acceptable to subjects if physically • more convenient.

Human-like behavior The child groups showed a dominant response to prefer the ‘social zone’ distance, comparable to distances people adopt when talking to other humans. From the single adult studies a small majority preferred the ‘personal zone’, reserved for talking to friends. However, significant minorities deviate from this pattern. M. L. Walters, K. Dautenhahn, K. L. Koay, C. Kaouri, R. te Boekhorst, C. L. Nehaniv, I. Werry, D. Lee (2005) Close encounters: Spatial distances between people and a robot of mechanistic appearance. Proc. IEEE-RAS International Conference on Humanoid Robots (Humanoids2005), pp. 450-455. A.G. Billard, Autonomous Robots Class Spring 2007
Summary • The robot’s face must be appealing to enhance the interaction • It must be able to express emotions to which humans can relate • Brain and body must match the robot’s capabilities must match the expectations raised by its body features • Simple designs can sometimes be more effective than highly complex and realistic ones • The robot must be endowed with basic social behaviors: • Joint attention, imitation, keep a desired distance.
