HCI

• What is it?
  • from MMI to HCI
• What happens when a human and a computer get together to perform a task
  • task: write document, calculate budget, solve equation, drive home, ...

Why is this important?

• Computers (in one way or another) now affect every person in society

• Product success may depend on ease of use, not necessarily power

  算力已经没有那么重要

Central topic

• Interaction design

  • Not just a software interface on a desktop monitor!

    Designing interactive products to support people in their everyday and working lives.

    ——Jennifer Preece, Yvonne Rogers, Helen Sharp

Goals of Interaction Design

• Allow users to carry out tasks

  • Safely

  • Effectively

    Having an intended or expected effect.

  • Efficiently

    • Acting directly to produce an effect
    • Acting or producing effectively with a minimum of waste, expense, or unnecessary effort.

  • Enjoyably

Two Crucial Errors

• Assume all users are alike

  假设所有的用户一样

• Assume all users are like the designer

  假设所有的用户与设计者一样

Improving Interfaces

Know the User!

• Physical abilities
• Cognitive abilities *
• Skill differences
• Cultural diversity **
• Personality differences
• Motivation
• Special needs

Aims of the course

• Consciousness raising
• Design Critic
• HCI foundations

Design Critic

• Useless Design
• Bad Designs
  • Things that don't work the way you expect
  • Things that get in your way
  • Controls that have unexpected functions

Discussions: Good design or bad design

Consciousness raising
