Abstract:
This paper describes a fundamental dual tradeoff that occurs
in systems supporting awareness for distributed work
groups, and presents several specific new techniques which
illustrate good compromise points within this tradeoff
space. This dual tradeoff is between privacy and awareness,
and between awareness and disturbance. Simply stated, the
more information about oneself that leaves your work area,
the more potential for awareness of you exists for your
colleagues. Unfortunately, this also represents the greatest
potential for intrusion on your privacy. Similarly, the
more information that is received about the activities of
colleagues, the more potential awareness we have of them.
However, at the same time, the more information we
receive, the greater the chance that the information will
become a disturbance to our normal work.
This dual tradeoff seems to be a fundamental one.
However, by carefully examining awareness problems in
the light of this tradeoff it is possible to devise techniques
which expose new points in the design space. These new
points provide different types and quantities of information
so that awareness can be achieved without invading the
privacy of the sender, or creating a disturbance for the
receiver. This paper presents four such techniques, each
based on a careful selection of the information transmitted.
Notes:
Privacy vs. Awareness vs. Disturbance (overload of information)
Co-located interaction is:
· Implicit
· Informal
· Serendipitous
Needs:
· Continuous fashion of sharing spaces
· Immediate awareness as a catalyst of communication
Techniques to meet awareness goals and preserve privacy and non-disruption properties:
· Privacy: THE SHADOW-VIEW & SHARED AUDIO
o What information is, can be, or should be transmitted in terms both of its awareness support content, and in terms of its effect on privacy.
o Reciprocity
· Disruption and high resource utilization: SHARED AUDIO (who's speaking but not what is saying & background noise)
o Partial control over interruptions in the hands of the receiver
o Do not consume too many resources (cognitive and machine)
· THE SYNTHETIC GROUP-PHOTO
· VISUALIZE A RECENT HISTORY OF ACTIVITIES (non-uniformly in time)
