Frameworks for HCI

• Folk HCI
• Humans as sensory processors
• Human factors, experimental psych
• Humans as interpreters/predictors
• Cognitive psych, AI
• Humans as actors in environment
• Activity theory, ethnography, ecol psych

9
What makes a system usable

• Humans as sensory processors
• Fit with human limits
• Humans are interpreters/predictors
• Fit with knowledge and task
• Humans as actors
• Fit with task environment and social context

10
HCI Methods

• Humans as sensory processors
• Quantitative evaluation
• Humans are interpreters/predictors
• Task analysis, Cognitive walkthrough
• Humans as actors
• Ethnographic field work, participatory design

11
Cognitive Frameworks

• Model-Human Processor (Card, Moran and Newell)
• Situated Action (Suchman)
• Activity Theory (Vygotsky, Nardi)
• Distributed Cognition (Hutchins)

12
Design Frameworks

• Graphic design
• Interaction design
• How to model the dialogue
• Industrial design
• Affordances
• Design as storytelling

13
Two view of interaction

• Interaction with
• Software as a tool or machine
• Interface is usability-engineered membrane
• Human as processor interpreter models
• Interaction through
• Software as medium to interact with task objects
  or people
  
• Interface plays a role in social context
• Human as interpreter actor models

14
Upcoming

• Usability Principles
• DFAB 4.3
• Design of Everyday Things
• Norman, Ch 1-4
• Project Part 0 (due 8/31)
