Chapter 2 - Making interactive systems feel natural for users

Question 1

What is Natural Computing

Answer 1

Study of how people Process data, Store information, Manipulate symbols, Ascribe personal values to events, AND how we use interactive artefacts

Question 2

Why Natural Computing

Answer 2

• Enables us to consider systematically the requirements of users of new interactive systems
• Provides framework to consider methods that designers can use to build systems that are more useful, usable and accessible
• Addresses user’s and designer’s perspective

Question 3

UCSD Steps (6)

Answer 3

• Task Analysis
• Requirements gathering
• Design and Storyboarding
• Prototype implementation
• Evaluation
• Installation

Question 4

Natural Computing Principles (6)

Answer 4

• Natural computing (humans/technologies manipulate symbols to perform computations)
• What can users do? (understand people who use technology)
• Modelling users (develop models to understand people better)
• Understanding the domain (understand working environment)
• Understanding human learning (understand, appreciate and apply principles of human learning)
• Meaning as a basis for practical action (links between theory and practice)

Question 5

Core Concepts of Interaction Design (5)

Answer 5

• User model
• Universal access (make systems that are accessible to anyone, anytime, anywhere)
• Design for all (be as inclusive as possible)
• Inclusive design (calculate users excluded by specific design feature)
• Task models (output of task analysis, produce system that performs tasks required by user)
• Technological platforms (intended technological platforms)

Question 6

Natural Computing Linked Aspects (3)

Answer 6

• User perspective
• Designer perspective (designer needs to understand intended users)
• Sustainability perspective (people use tools for survival, support strengths and weaknesses)
