Disciplines contributing to HCI

• Ergonomics

• Information Technology

• Design

• Physics

• Engineering

HCI is about:

• Understanding the users

• Understanding users tasks

• Evaluate prototype

• GUI requirements gathering and analysis

• Design the system

HCI is not about:

• Making the interface look pretty

• Only about desktop computers (and that goes for computing as well!)

• Something that would be nice to do but usually there’s more time for it

What is Usability?

• resulting interfaces are easy to use

• efficient for the task

• increase users loyalty

• ensure safety

• lead to a incorrect completion of the task

Basic misconception about HCI

• If I (the developer) can use it, everyone can use it

• If our non-technical staff can use it, everyone can

• Good user interfaces are applied common sense

• A system is usable if all style guidelines are met

• Increase mistakes in data entry and system operation.
