robots in museums - an analysis of best practice in hri
DESCRIPTION
The Talk presents a Meta Study of 60 Papers about Social Robots in Museums. The specific scenario "Tour-Guide Robot" provides several challenges, social Robots have to accomplish for everyday life usability (e.g. "sponateneous short-term interaction"). Due to this between 1996 and 2005 more than 25 different Robots were built for museal Use. I I evalueted these Robots concerning their attributes in Human Robot Interaction: - How did the constructers modelled the User? - What was the Project Goal / The Main Task of the Robot - How could the robot 'interact' with visitors - What results brought up the implementation in the real life environment Museum? As conclusion the Presentation introduces three different Examples of Museum Robots to show two main principles for HRI: honesty and deception.TRANSCRIPT

Cultural Concept „Robots“
ANCIENT WORLD
- artificial, man-like, subserving (i.e. Talus)
MIDDLE AGES & RENAISSANCE
- mechanic / automatic (DaVinci, Al-Jazari)
- souled, threatening (Golem)
18th & 19th CENTURY
- androids (Jaquet-Droz, E.T.A. Hoffmann )
- artificial life (Frankenstein‘s Monster)
20th CENTURY
- Robots as Members of Society
- Robots as Replacement for Humans

1. What Robots?
Social Robots as border crossers
- Informational Gap due to Perspective Problem: users are not experts; creators
are not users
- People make sense about machines:
Theory of Mind
Uncanny Valley
- Robots in social and everyday scenarios are confronted with these cultural
concepts!

2. Robots in Museums
Scenario „Tour-Guide Robots“
Challenges:
crowded ‘real’ environment, no laboratory
uninformed, untrained users
set of everyday tasks
short length of use „Spontaneous Short-Term Interaction“
Motivations:
Robots as Demonstrators
Robots as learning objects
Robots as attraction for museal context
Robots as Products

Minerva – The Pioneer
Features making her a Trendsetter:
- on the fly task planning
- constructors aim: „believable agent“ - display internal states to reach attended goals

3. Designing HRI
Colliding Term “Interaction”
Having ideas, lacking Methods
Results of Inquiry
2 principles
![Page 19: Robots in Museums - An Analysis of Best Practice in HRI](https://reader034.vdocuments.us/reader034/viewer/2022052601/558b79a6d8b42a417b8b472c/html5/thumbnails/19.jpg)

3. Designing HRI
Human Robot Interaction: Colliding Definitions of „Interaction“
Informatics: one-way; Human > Computer
i.e. dragging, pushing, zooming, manipulating
Average Joe: mixture of both; tends to anthropomorphise
technical artifacts
Social Sciences: both ways; Human <> Human (or others?)
i.e. talking, coordination on sidewalk, presenting a paper
![Page 20: Robots in Museums - An Analysis of Best Practice in HRI](https://reader034.vdocuments.us/reader034/viewer/2022052601/558b79a6d8b42a417b8b472c/html5/thumbnails/20.jpg)

3. Designing HRI
Having Ideas, lacking Methods
- a lot of (successfull) ideas in designing HRI, but no methodical reflected
procedures to modell user or specific interaction scenarios up front
- i.e. „What does it mean for the user to be in a Museum?“
- Newer developments: Axiomatic Design, Interaction Design

3. Designing HRI
What is the problem about this HRI trial and error?
What they say… … what happens
We thought…
The Robot does…
… this specific Voice /
Content / Menu would
be approperiate.
… recognizes
person, asks for
aternatives.

3. Designing HRI
Nevertheless they evaluated HRI (3 out of 60 papers)
- "people are basically destructive" (Nourbakhsh et al. 2002a)
- most attracting: motion and awareness of human presence
- most effective: dialogical interactions, multi modality
- Physical design: height between 1.50 - 1.60 m for interactional robots
- Children are significantly higher attracted by robots than adults
![Page 23: Robots in Museums - An Analysis of Best Practice in HRI](https://reader034.vdocuments.us/reader034/viewer/2022052601/558b79a6d8b42a417b8b472c/html5/thumbnails/23.jpg)

Which principles make HRI successfully? (making the other 57 papers talking)
- Knowing about interactional structures makes robots better interaction
partners
- Form follows function: HCI input can be adopted easily
- Perception of humans in a human way raises potential for adaptive behaviour
(from „something?“ to „somebody!“)

3. Designing HRI
both principles can achieve trust (Reliability)!
both principles can lead to Uncanny Valley problems!
„Honesty“
transparent design:
tutorial-welcoming
showing (real) states and goals
allowing the user to understand
the machine‘s (and it‘s
constructor‘s) intention
„Deception“
impressive design:
character design
use of professional Storytellers
using the (cultural and social pre-
formed) narratives and Typecasts
of everyday-life

4. What‘s up?
Fields to improve
(technical & HRI)
Everything concerning human speech
more ‚natural‘ HRI
Multi-User Usability (i.e. age)
Interacting with Web Devices Locomotion Concepts
adjust robot‘s features to the Museum‘s goals

Questions for our Project
- Motivation: learning object, demonstrator, museum feature?
- Scenario: What Problem does the robot solves in the Museum?
- Fame: What do we do better than others?

4. What‘s up
Just an Idea…
- foster interactions between visitors
- attach robot features to the museum‘s needs
- foster collaboration between graduate school members
