Title: Cyberworld, Dissapearing Computer, Hybrid Products?

Cyberworld, Dissapearing Computer, Hybrid
  • Josep Blat
  • Universitat Pompeu Fabra

Trends towards the future
  • Cyber-VR worlds, Augmented Reality
  • Disappearing computer - Information appliances
  • Hybrid products

Information Highways Semantic Web
  • Already discussed
  • Standards for an interconnected world
  • the Internet network (TCP/IP ) for
  • the World Wide Web (URL, HTML, HTTP) for
    information exchange
  • Information and intercommunication widely
  • Machine mediated communication to be built
    Semantic Web perspective

Cyber-VR world
  • Virtual Reality, Virtual Environments have been a
    perspective of the future for years
  • A simulated (or re-created) world, especially the
    sensory aspects
  • Head-mounted displays, haptic devices such as
    cybergloves, cybersuites, for immersive VR
    lately CAVEs
  • Natural interaction paradigm, not mediated by
    the computer display, icons,

Limitations of Cyber-VR world
  • Huge costs at the beginning, now migrating to
    desktop (flight, medical, CAD simulators, )
  • Why simulating? Why not inventing?
  • Difficulties of the natural interaction paradigm
    understanding psychology and how senses perceive
    long-term effects
  • Difficulties of integration with other paradigms
    (e.g. hypermedia)

Perspectives of Cyber-VR world
  • Some current approaches Shared VR, Networked VR
  • Augmented reality paradigm
  • Superimpose simulated realities on realities,
    (ruins and reconstructions for instance)
  • Not a cyberworld but an augmented real one
  • Use of special glasses, cameras,
  • Non-intrusiveness as a key question

Example AR application I
Feiner (91), application to support a
procedural maintenance routine
User sees the instructions overlayed on top of
the real world
Prototype apparatus
Example AR application II
  • Example prototype system from Columbia
    University tourist application

Prototype tour guide
Heres what the user sees
Ubiquitous computing
  • A completely opposite paradigm to the cyberworld
    no suits, no special separation of computers
  • Computers in watches, in cars, in household
    appliances (fridges, ) and more tags, pads,
    boards everywhere. They are ubiquitous
  • Experience from history a multiple use engine
    requiring engineers for maintenance now one (or
    many) engines for each appliance.

Invisible computers and information appliances
  • The other aspect is invisible computers
    (disappearing computers) as in the watch the
    computer is not observed
  • Paradigm of specific uses of computers one (or
    many) computers for a specific use, not a
    computer for lots of things
  • Information appliances, a term used by Don
    Norman, as well as the invisible or disappearing

Awareness for ubiquitous computing
  • (Situated) awareness is a key aspect for the
    computers to be increasingly useful where they
    are, who is in the room (who is looking at them
  • Definition of awareness The ability of a device
    or program to sense, react or adapt to its
    environment of use.
  • Awareness communication (a living world of
    agents) A key problem solutions (competition for

Uses of ubiquitous computing
  • Tags, Pads and Boards give idea of sizes of many
    computers they can use awareness
  • Boards can show the information interesting for
    the person looking at the board
  • Pads can show the software being used by the
    persons in the room
  • Tags can carry information (persons, software, )
  • Much richer uses

Ubiquitous environment Wearable computing
  • One aspect of ubiquitous computing is an aware
  • Another aspect is wearable (aware) personal
    assistants (also cyborg vision)
  • Both use awareness for improving interaction,
    better services, sensing, new services

Hybrid products
  • Another aspect of the future are hybrid products,
    e.g. computational toys (robots )
  • Which is the interface of such a product?
  • Which is the interaction paradigm?
  • Exploration with the éTui project
  • Other hybrid systems mixed realities,

éTui introduction 1
  • Computational toys (Tamagotchi, Furby, Aibo, Lego
    Mindstorms, curlybot, ) are attracting a lot of
    commercial and research interest.
  • éTui a prototype computational educational toy,
    based on a commercial robot kit, for children of
    very young age (6-10 years old)
  • (introducing éTui to children)

éTui introduction 2
  • The educational goal meta-cognition
  • Interface design appearance
  • Interface design autonomous behaviours scaffold
    reflection upon learning
  • Co-design with children

éTui educational goal meta-cognition
  • Meta-level learning means learning about
    learning, reflecting about learning our
    educational goal
  • Meta-cognition very little explored for young
  • éTui, a wearable computational toy for reflecting
    upon learning
  • Constructionism is our philosophy
  • I began to see how children who had learned how
    to program a computer could use very concrete
    computer models to think about thinking and to
    learn about learning and in doing so, enhance
    their powers as psychologists and as
    epistemologists Seymour Papert

éTui appearance part of the interface 1
  • Appearance is a (key) part of the interface for
    computational toys
  • Appliances should show their psychology (Don
    Norman) e. g. handles should show themselves as
    such even how to be used
  • ActiMates (Strommen et al) When the interface is
    a talking dinosaur Interface for a plush doll (a
    bear) related to a TV series, connected to a VCR
    speech oriented interface, narrative, affection,

éTui appearance 2
  • éTui should to deal with
  • Engagement (emotional attachment) for better
    education (intelligence emotion)
  • Gender related characteristics
  • Educational goals fulfilment (potential deception
    of toys?)
  • Translate that into shapes, colours, movement

éTui appearance 3
  • From our co-design work éTui
  • A key aspect for engagement is characterization
    ease of identification is an added value
  • Pet-like appearance appeals girls and pets
    attract children generally (besides being a good
    model for learning)
  • Movement is an essential trait for attracting
  • Insect-like appearance for non-deceptive behavior
    (éTui is not very intelligent and thus it
    shouldnt look too clever)

éTui appearance 4
  • Finally éTui is a moving robot with an
    insect-like appearance lights and sounds add a
    communicative aspect

Co-designing with children 1
  • Brainstorming with children (preferred toys,
    imaginary toys, stories about them) 3 schools in
    Mallorca, UK, Norway
  • 2D prototype designs based on childrens ideas,
    tested by using colouring books parameters were
    color, texture, character, animated or mechanical
    nature, and cuddliness or scariness
  • Four VRML designs (chick, mouse, car, robot),

Co-designing with children 2
  • 2D identikits for the physical appearance
    bodies, ears, eyes, mouths and noses
  • Storytelling about toys designed toy name, toy
    gender, where it lives, home, food, can smell,
    can hear, can see, can recognize you, can talk,
    understands, is clever, likes to do, how plays,
    take to bed, type


Co-designing with children 3
  • Children
  • prefer round body shapes, particularly with a
    high profile
  • prefer face elements from known animal forms
  • identify strange creatures as destructive or
  • prefer soft rather than rigid surfaces
  • associate sense organs to creature perception
    with that sense
  • (Insect-like antennae rather than eyes as éTui
    cannot see)

éTui autonomous behaviours scaffolding
  • Autonomous behaviours stimulate children to
    reflect upon learning as modified behaviours in a
    changing environment
  • With éTui we explore the advantages of autonomous
    behaviours for scaffolded reflection upon
  • Wandering insect, Towards beacons, Learn tracks,
    Learn tunes, Play tunes, Follow line

Interaction with éTui, awareness limitations
  • Children interact physically and directly with
  • Create mazes, blocking éTui, following
    (inpersonating) éTui,
  • It is a hybrid world
  • éTui is not aware. It should know at least
    that it is being held it lacks credibility, big

éTui should help reflecting about perception,
autonomy, learning
  • Experimental work with children pedagogical
    Units of Practice
  • éTui wandering for reflection on perception
  • éTui in a maze for reflection on autonomy
  • éTui learning a path for reflection on learning

Summarizing (partly) éTui
  • Review of éTui experience as a model of new
  • Hybrid product in hybrid world
  • New type of interface, new type of interaction
  • New types of problems in a disappearing computer
