Gerhard Fischer 3 University of Vienna, January 2011
Cognitive Informatics definition: the multidisciplinary study of cognition and information sciences,
investigating human and computational information processing mechanisms and processes
objective: explore foundations and develop technologies
o facilitate and extend the cognitive capabilities of individuals and groups through the development and application of novel concepts in human-system integration
o address cognitive bottlenecks (e.g., limitations in attention, memory, learning, comprehension, visualization abilities, and decision making)
multidisciplinary field focused on
o understanding natural systems (people) o designing artificial systems (information and communication technologies) o creating hybrids of the two: symbiotic systems, socio-technical environments

Natural Science Sciences of the Artificial <<Herbert Simon: “Sciences of the Artificial”>>
natural science sciences of the artificial (= design)
- natural science: how things are; primary interest: analysis; examples: physics, chemistry
- design: how things ought to be - primary interest: synthesis - examples: engineering, medicine, business, architecture, painting,
universities, cognitive artifacts, notations Cognitive Informatics = part of the Sciences of the Artificial (Design)
taking findings from the natural sciences (e.g. neuroscience) into account - design problems are complex, ill-defined, have no (single) answer, unique (“a
universe of one”) - design leads to changes: “Philosophers interpret the world in various
ways; what matters is to change it!” — Karl Marx

Grand Challenges a Grand Challenge = a commitment by a scientific community to work
together towards a common goal — valuable and achievable within a predicted timescale
purpose and impact of a Grand Challenge: to change the discourse that
drives research and practice examples of Grand Challenges
o getting a human on the moon (1961; John F. Kennedy: declaring a national goal of “landing a man on the Moon” by the end of the decade)
o Grand Challenges in Environmental Sciences (a book published by National Academy Press in 2001)
Gerhard Fischer 13 University of Vienna, January 2011
Grand Challenges in Technical Computer Science versus Cognitive Informatics
High Performance Computing and Communications program (HPCC,
started 1991): o major problems of science and society whose solutions require 1000-fold or
greater increases in the power and speed of supercomputers o research and education relative to HPCC must link a broad range of sciences o multidisciplinary settings offer the best chance for success
HPCC: an “easy” (?) Grand Challenge Problem because:
o objectives are not controversial (increase speed of computation, increase storage capacity, increase bandwidth
o simple measurement of progress exist
Cognitive Informatics: a “difficult” (?) Grand Challenge Problem
Gerhard Fischer 14 University of Vienna, January 2011
Grand Challenges: Where Do They Come From? Marshall McLuhan: “I donʼt know who discovered water, but it probably wasnʼt a
fish” o beyond group-think o interaction with other disciplines
George Bernard Shaw: "The reasonable man adapts himself to the world.
The unreasonable man persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."
o think outside the box Winston Churchill: "This is not the end. It is not even the beginning of the end.
But it is, perhaps, the end of the beginning." o do not assume that we are done (e.g. the true potential of the Internet? it is
only 15–20 years old) o in which way can we look 15-20 years into the future??

Driving Forces behind Research in Cognitive Informatics
“New and deeper understanding does not start with perceptions, observations, or collections of data but it starts with problems.” — Karl Popper
fundamental problems (e.g.: aging populations, energy sustainability,
learning and education in the 21st century, creativity, ………….) visions (e.g.: Memex (Vannevar Bush, 1945); Dynabook (Alan Kay, 1972)) theories (e.g: about distributed cognition, design, learning, collaboration,
motivation, …..) systems / technologies (e.g.: personal computer, WIMP interfaces,
Gerhard Fischer 16 University of Vienna, January 2011
Objective: Doing Basic Research on Real Problems —
Models and Examples real problems are systemic problems (transcending individual human minds
and individual disciplines) examples of real problems:
o from the “Renaissance scholar” to the “Renaissance Team” (or: from the “reflective practitioner” to the “reflective community”) collaboration
o from ”automate” to “informate” distributed cognition
o rethinking learning and education co-evolution of learning, new media, and
new learning organizations

narrowness” Campbell, D. T. (1969) "Ethnocentrism of Disciplines and the Fish-Scale Model of Omniscience."

Human Attention and Information scarce resource is not information but human attention — claim: “a design
representation suitable to a world in which the scarce factor is information may be exactly the wrong one for a world in which the scarce factor is attention”
attention from a neuroscience perspective information processing in the
brain attention from a Cognitive Informatics perspective
From “Anywhere, Anytime, Anyone”
“The Right Information at the Right Time, in the Right Place, in the Right Way to the Right Person”
Gerhard Fischer 22 University of Vienna, January 2011
The Right Information at the Right Time, in the Right Place, in the Right Way to the Right Person
right information: relevant to the task at hand task modeling right time: intrusiveness (pull versus push) right place: location-aware systems (e.g.: smart tour guides) right way: multimodal presentation (textual, visual, auditory, tactile) right person: taking background knowledge and interests of specific users into
account user modeling (“who do I ask and who do I tell”)

Cultures of Participation
consumer cultures focus: produce finished goods to be consumed passively
⇓ cultures of participation
focus: provide all people are with the means to participate actively in personally meaningful problems
impact: democratizing innovation, creativity, giving all people a voice, end-user development

L3D’s Research Supporting and Fostering Cultures of Participation table-top computing systems for framing and solving complex urban
planning problems theoretical frameworks
o meta-design = design for designers (supporting users in becoming active contributors)
o SER Model for open systems: seeding, evolutionary growth, reseeding examples:
o modeling all the buildings of the world in 3D (in collaboration with Google-Boulder: SketchUp +3D Warehouse)
o using Smart Grids to support energy sustainability o courses-as-seeds

The Envisionment and Discovery Collaboratory: A Socio-Technical Environment
Gerhard Fischer 28 University of Vienna, January 2011
Basic Message — Cognitive Informatics: An Important and Exciting Discipline for the Future
transcending the individual human mind collaboration (“Renaissance
Team”), cultures of participation identifying the most productive mix of distributed cognition (i.e., what tasks
or components of tasks are or should be reserved for educated human minds, and which can and should be taken over or aided by cognitive artifacts) socio-technical environments, symbiotic environments
shifting from a concern about who has access to new information technologies
to who will have the knowledge that will position them to design, create, invent, and use the technologies to enhance their personal lives and social worlds lifelong learning and education
challenge: create a branding and identity for a specific program (such as Cognitive Informatics at the University of Vienna)
with the objective of “Being a Leader versus a Follower”
