description
In the last 30 years, the desktop metaphor has become the standard user interface for workstations, with its pros (e.g., ease of learning) and cons (e.g., interaction constraints for skilled users, lack of context awareness). In this tutorial we present itsme, an initiative to create the next-generation workstation – especially designed for users who think that what they do holds value. Much of what we present derives from CSCW research, while Interaction Design research shapes the project, as well as the involvement of a wide and heterogeneous community of contributing people. The early design phases of the project led to the definition of a new metaphor for personal computing, called ‘stories and venues’. The metaphor is being adopted for the development of a radically new front-end for the Linux operating system. The tutorial illustrates (through the itsme case) how CSCW research can drive the design and development of an innovative project

The scenario
May 2009 4
1984: during the Superbowl
Apple launches the Macintosh
A new personal computer with a
graphical user interface based on the
desktop metaphor
It delivers the ideas developed at
Xerox PARC by Alan Kay (and
colleagues) to a large public, at a
reasonable price
May 2009 5
The desktop metaphor
Based on similarity with physical
environment
Familiar tools and operations
Reflecting some specific work
practices
May 2009 6
From the ‘90s on
All personal computers adopt the desktop metaphor
There is a dramatic growth of the size of internal and external
(fixed and removable) memories of personal computers
The email becomes a universal medium
The Web, invented by Tim Berners-Lee, evolves far beyond some of
the PC limits (e.g., social computing)
May 2009 7
Problems of the desktop metaphor
Very dependent on the culture (of the designers) (Olsen andKorfhage 1994)
Implies a physical organization of elements that is tightly coupled tothe logical organization, and vice versa
Requires memorizing where a lot of stuff is (Ravasio et al. 2004)
Depends on hierarchical file system
OK for a limited number of items, if each item is meant to be available in asingle place (and not in different contexts), as long as the user is able andwilling to keep things sorted
well known since the ‘80s
May 2009 8
Additional problems with the user interface(Ravasio et al. 2004)
Concerning the interface: the desktop metaphor should help noviceusers but it does not, the screen plane is regularly misused andovercrowded, skilled users are irritated by similarities between thescreen plane and the file system’s interface, and the user interfaceis too intrusive
Concerning the underlying system: the separation between files,email and bookmarks is inconvenient, temporary material (shortterm notes) are not supported, resources cannot be linked even ifthey belong together, classification and gaining overview impliesadditional effort
May 2009 9
Three main problems with PCs
The personal computer has been unable to cope with the evolution
of the Cyberspace:
information overload (from keys to gigas; more and bigger objects)
dispersion of information (in the file system, attachment folder, e-mail,
browser)
backwardness of the PC file system with respect to the Web (no tags,
hyperlinks, and structure)
May 2009 10
Today
On-line computing is not yet ubiquitous
The PC lacks some capabilities, compared to the Web
Different users have different needs and desires
Who has control?
May 2009 11
How to possibly solve these issues
Refer to better metaphors (also non-physical)
Get rid of hierarchies (when they are not needed)
Learn from the Web (e.g., folksonomies)
Put the user, and not the workplace, at the center of the world
There is a lot of (forgotten?) research literature from which we can
learn how to do it
May 2009 12
CSCW research: basis for innovation
May 2009 13
The early CSCW debates
CSCW community formed in the mid ‘80s
The early years of CSCW were extraordinary for the number of new
ideas that were presented to its conferences and for the passion
animating the discussions raised by them
May 2009 14
Winograd & Flores
Language-action perspective
Inextricable binds linking together words and actions, conversations and
interactions
The concepts of ‘conversation for action’ and of ‘commitment for future
action’ has deeply influenced our research for over twenty years (e.g., De
Cindio et al., 1986; De Michelis and Grasso, 1994)
May 2009 15
Suchman (vs. Winograd)
Situated action perspective
Very nature of human practice, its being situated in space and time and
within the experiences people share during their life
Sharp dispute with Winograd and Flores (Suchman, 1987b, 1994; Winograd,
1995), but we think they offer complementary views (De Michelis, 1995)
May 2009 16
Holt
Coordination theory with the idea of centers
Projects as networks of inter-related centers
Better having a personal system than one shared by all the participants to a
cooperative process
May 2009 17
Dourish
Concepts of place and of embodied interaction
May 2009 18
Malone et al.
Semi-structured messages
Even text objects like messages contain a structure where you can find
some information that can be used to trigger agents and/or commands
Coordination Theory
May 2009 19
Our idea, itsme vision:Stories and Venues
May 2009 20
A new workstation
Helping to avoid the dispersion of information
Embodying what we know about knowledge work
Designed for those people who “think what they do holds value”
Based on a new metaphor: ‘stories and venues’
May 2009 21
Avoiding the dispersion of information
A new front-end where:
Related objects, messages, urls, people contact details, information sources,
and tools appear together
All objects are characterized by tags and links
A ‘back-end’ enabling Linux to support it
May 2009 22
The lessons of ethnographic research on work
What human beings do is embedded in their relations with other
people: actions and interactions
Action and communication are strictly intertwined
Any action is situated in space, time and, often, in the story within
which it has sense
The stories a person lives are not disjoint
Stories are viewpoints on actions and interactions
May 2009 23
The target users of itsme
High-value users, i.e., all those who have a great number of
interactions with other people, manage loads of information, live a
great number of stories at the same time, but do not have adequate
support to manage the complexity of their life
Professionals
Managers
Intellectuals
Knowledge workers
May 2009 24
A new metaphor: ‘stories and venues’
Our life interweaves a large number of different stories
Each story has its participants and objects
Each story has its venue, where you can access its participants and
objects
Each person lives in several diverse interweaving venues
The new metaphor is characterized by its being plural and its
reflecting situatedness of human experience

itsme workstation scheme (vision)
May 2009 27
itsme: a workstation based on the metaphor of ‘storiesand venues’
At any moment, itsme presents the venue of the story in which its
user is acting
itsme users do not need to search for things: they have them at
hand
itsme creates, maintains and updates the venues of its user
itsme venues can be corrected, modified and organized by its user
itsme is not intrusive: its behavior is purely reactive
May 2009 28

The help we need
Three active communities, supporting itsme from the very beginning:
Research (CSCW, KM, ID)
Open source software (Linux community)
High-Tech industry (particularly in Europe)
Good coverage of Itsme milestones by media and research community world-
wide
Support from public institutions in Italy and Europe

Next steps in communication
Presentations in major Universities/conferences
Courses at major Universities and Educational Institutions
Collaboration with research groups on itsme’s issues and related
topics
May 2009 52
Conclusion
The desktop metaphor can no longer support effectively personal
computing
CSCW research provides the basis for innovation
itsme is implementing next-generation personal computing
We are an open community, in which you are welcome
