Study Notes

Human Computer Interaction (HCI) Introduction

  • Interest in building more effective weapons led to studying humans and machines.
  • Ergonomics Research Society (1949) focused on the physical characteristics of machines and systems, and how they affected human performance.
  • HCI includes the computer as the machine.
  • HCI tries to answer questions about technology, and how to evaluate it.
    • What makes a good and bad technology?
    • How can good technology be built?
    • How can good technology be validated?
  • Good and bad technology depend on perspective. Some technologies are designed for a specific purpose.
    • Examples include Nikon's ergonomic design, vs Canon's video recording features, and Apple's security vs Android's versatility.

Human Computer Interaction Components

  • HCI is composed of computers, humans, and tasks.
  • There is no unified theory due to culture, changing standards, and other factors.

User Experience vs. User Interface

  • User Experience (UX) is the overall experience of using a product, like a website or app. How easy and enjoyable is it to use?
  • User Experience encompasses all aspects of the user's interaction with a company, its services, and products.
    • Example: Why are people addicted to Facebook? What makes them repeatedly do something?
  • User Interface (UI) is the space where interactions between users and machines occur.
    • Computers have three UI interfaces for different senses: vision, hearing, and touch. (monitors, projectors, screens, VRs; microphones, speakers, headsets; buttons, pens, touchscreens.)

Usability

  • Usability is a major but abstract component of HCI. It involves the ease and use of objects that humans interact with.
    • Usability is subjective and measured through testing.
    • Techniques used include user-centered interaction design.

Design Principles (Donald Norman)

  • Affordances: How to use something.
  • Constraints: Why limitations exist.
  • Conceptual models: Previous experience.
  • Mappings: Where something is.
  • Visibility: Can we see it?
  • Feedback: What is the system doing?

Usability Metrics

  • Different types include performance-based, issue-based, self-reported, and behavioral/psychological.
  • Performance metrics determine the magnitude of a specific usability issue.
    • How many people are likely to encounter a problem.
  • Common examples include task success and time on task.

Design Thinking

  • A non-linear process for tackling complex problems in product development.
  • User-centric approach.
  • Aims for practical and logical innovation.
  • Steps include empathize, define, ideate, prototype, and test.

Module Summary

  • HCI focuses on creating good design.
  • It is composed of humans, computers, and tasks.
  • UX is different from UI.
  • Usability is an important component and can be measured through metrics.
