Intro

Field Tests - Observing People´s reaction based on the book “HRI for Social Robotics”

laboratories

well-controlled situations

develop general functions and behaviors for the robot without

context

sensory data - robotsensor network to monitor the

robot

real services for real world (start= elementary schools)how real people establish relationships with robots

teleoperated robot (at the beginning)

data - robot AND environmentsensor network primarily to understand PEOPLE´S BEHAVIOR

BETTER APPROACH?

Field Test in a SCIENCE MUSEUM based on the book “HRI for Social Robotics”

citation:Interactive Humanoid Robot for a Science Museumby M. Shiomi, T. Kanda, H. Ishiguro, N. Hagita2006

Science Museum - MotivationRobovies interacted with the visitors and showed them around to exhibits according to information from ubiquitous sensors.

During the two month experiment, visitors enjoyed interacting with the robots and highly appreciated them.

1. for visitors opportunity to experience the advanced technologies: fundamental purpose of a SM - easily deploy research to a real environment.

2. targeting people interested in robots: SM one of the best choices for collecting feedback and examining the HRI.


WHAT?

WHY?

Science Museum - Experimental Settings

sensors to work in a complex, crowded environment: cameras + wireless tag readers (RFID)

coordinates for the robots & call visitors by names, recommendations based on movement history


● 20 RFID tag readers (2 on robots), 3IR sensors, 4 video cameras. ● 1 humanoid - guide to the exhibits, 2 stationary - explained the exhibits, 1 robot greeting and

asking them to return their RFID tags● central database - interaction data between robots and visitors: Ethernet

Science Museum - SENSORSFor friendly interaction with visitors, robots need information about them (interest increases when the machines call them by name) ->

SENSORS:1. robots can act more intelligently. 2. robots contain an RFID tag readers -> not only interactive robots but also part of the sensor

system.



Science Museum - Scenario

Science Museum - Experiment


Science Museum - Experiment


2-month period, visitors 91107, with RFID tags 11927 and 2891 returned questionnaires

Questionnaire by ranking five factors on a scale of 1-to-5

Moreover, visitors asked to: give opinions on robots- We had a really good time. - I had fun because the robots called me by name. - We felt close to the robots. describe their favorite robot behavior such as hugging, the calling out of names, and so on (basic elements of human society).

Science Museum - Conclusion● human-like body attracts people and enables human-like interaction

(shaking hands, pointing...)● tactile interaction capability - effective● lack of speech recognition● human identification (this case-RFID) must be robust (visual and

auditory difficult in noisy real world!)● infrared camera - exact position of the robot - very helpful in crowded

environment


citation:Humanoid Robots as a Passive-Social Medium -A Field Experiment at a Train Stationby K. Hayashi, D. Sakamoto, T. Kanda et.al.


Field Test at a Train STation based on the book “HRI for Social Robotics”

Train STation - MotivationUsing robots as a passive social medium, in which multiple robots converse with each other

Field experiment at a train station for eight days to investigate the effects of a passive social medium

1. If the robot(s) is “interactive” with people by bowing to them before announcing the information, the people will get a stronger feeling of being addressed by the robots

2. If a robot is passive toward people without reacting to them, people will pay more attention to the information coming from the robot(s)

3. People are more likely to stop to listen to the robot’s conversation in a two-robot condition than in a one-robot condition


WHAT?

WHY?

Train STation - Experimental Settings

The system consists of a sensor and humanoid robot(s)


The robot(s) announces various features of the new train line


Train Station - Scenario

Train STation - Experiment


Train STation - Results

5900 people were observedQuestionnaire (163)Analysis of behaviors - ignoring (370), noticing (260), stopping to watch (110), staying (1), touching (1), changing course to investigate (50), talking about robot(s) (7), watching with child (15)


Train STation - Conclusion

social expression vs. limited-realistic interactivitypassive-social medium - most effective way of attracting people’s interest in the informationinteractivity - useful in giving people the feeling of talking with the robots


Passive vs. interactive social robots, which one

is better and why?

Inspirational Questions:let´s discuss

Why to go outside of laboratories to perform

experiments?

What can the sensory network (smart/intelligence

space) serve for?

How do we measure the quality of the human-

robot interaction?

What are the (dis)advantages of using autonomous versus

teleoperated robots in the first real-world HRI

experiments?

How to design an experiment in the wild? What is the first thing to do when designing an

experiment?
