Big Points
Communication and information have many meanings
The value of a model in reducing complexity
Meaning (rather than info) constructed by receiver
Human need for balancing order and novelty
Perfect order makes communication impossible (comm.
implies change)
Compression based on predicting info units.
Design is a form of communication
Questions
What is exoinfo (unclear if I said XML info)
Info and meaning relationship?
Information and uncertainty relationship (more
choices seems to imply more info, but getting the ‘info’ on the receiver side
reduces more uncertainty)
What portion of a message is correctly interpreted?
(can we tell? Distinction between
intention of sender and interpretation of receiver, also nature of ‘truth’ and
meaning—whether relative or absolute)
What do the latencies to get back to homeostasis
imply for the system?
How to incorporate feedback?
Coding techniques vs
encryption techniques?
How do we talk about/study the info that people do
NOT receive (e.g., lack of understanding)?
Does this apply to visual or aural media?
So what? Who
cares about any of this and how does it apply to XYZ?
Class definitions. Perfunctory and creative.
Information
senses:
Thing/object
(what we handle, transmit, store)
Process
(act of informing)
The
change in mental state (signal—data—information—knowledge—wisdom)
Signal
(mass/energy)
Data
(ordered mass/energy)
Information
(data in a human)
Knowledge
(formalized information and skills—represented mentally and/or physically)
Wisdom
(the experience to know the differences)
Communication
senses:
Process involving:
Two
or more (human) participants (sender/receiver, creator/audience, etc.)
Sender
(initiator, creator, etc.) has intention
Receiver’s
mental state changes
Time
ranges from 0+ to infinite
May
be unidirectional
Object
Interaction
senses:
Mutual (reciprocal) action (process)
Two
or more objects (often we are concerned with one being human)
Either
may initiate, may be unintentional/random
States
of both objects change
Time
ranges from 0+ to infinite (but most often concerned with small latencies)
Always
bidirectional (feedback required, typically multiple cycles)
What
might it mean to interact with information?
Does information change when we ‘interact’ with it?
How
does digital information affect the possibilities of interaction?
For
HII do we also include the inferences and uses made of information?
Schramm (Li Zhao and Nancy Wilson)
Tannen (Deborah Williams)
Arkin (Justin Watt)
Maibach (Nan Wang)

learned in class today?
What is the main, unanswered
question you leave class with today?
