Information Processing Model of Cognition

What does this imply?

Personal computing: empowering the individual --> interface designed and optimized for the individual.

But we live and work with other people. Our computers are connected to other

computers.

Computer Supported Collaborative WorkNorth American

Computer Supported Cooperative WorkEuropean (and ACM)Often uses “participatory design” method

Computer Supported WorkAka “Knowledge work”“Do you want fries with that?”

A few terms:

Synchronous IM, chat Asynchronous e-mail Remote Colocated “in the

same physical space” Flow “really getting

into it” Work flow “the passing

of artifacts from one person to another for different processing”

Participatory design getting users to actively design with designers

Seamlessness integrating control into activity of application

Deictic reference resolving “this” and “that” e.g. pointing

Ubiquitous Computingaka “Pervasive Computing”

Mark Weiser / PARC (also Roy Want, Rich Gold, me, others)

Instead of 1 computer / person, 100’s / person

HCI consequence:100’s of interfaces / personEach one does single taskEach can be simple interfaceEmbedded in environment

Ubiquitous Computing

From Ubiquitous Computing

to “Pervasive Computing”Analogs of writing surfaces:

Whiteboard/wallsize --> “Liveboard/Smartboard”

Notepad size --> laptops and notepad

Scrap paper --> PDA’s

From Ubiquitous Computing

to “Pervasive Computing”McCullough’s Three Milestones of

Interaction Design:1. People and Machines (1920-1960) designers reduce “friction”, make safer, sell more products

2. Personal Computing or HCI (1960-2000) designers help people participate in computing, make useable, and create tools that match cognition

3. Interaction Design (2000- ????) Information technology is the ambient social infrastructure; designers create context a well as content.

Design Consequences

Design everything -- hardware, software, use, social setting

Highly contextual -- in fact, context is part of the design

Requires added design skills and experience
