Level 1 External AS92006

Demonstrate understanding of usability in human-computer interfaces

About

Human-Computer Interaction (HCI) is a multidisciplinary field that focuses on the design, evaluation, and implementation of interactive computer systems, with the ultimate goal of enhancing the interaction between humans and machines. HCI is concerned with studying how users interact with technology, understanding their needs, and creating user-friendly interfaces that facilitate efficient and satisfying experiences.

This NZQA standard 92006 is an external examination worth 5 Credits. The exam is on Tuesday, 18th November 2025

At the start of each lesson have a look at one of the following websites. What makes it a poor design? Each website has a link underneath it to a discussion or explanation for why the website exists.

Task 1: What can go wrong?

In small groups watch one of these videos and do a quick investigation about one of the scenarios about what could go wrong with software and user interfaces. Then assemble a group of different experts and explain it your classmates.

Task 2: Exploring Tikanga and Mātauranga Māori

The Computer Science Field Guide has recently released a unit on mātauranga Māori. Read the webpage and awnser the questions on the worksheet. After this read the article by Keegan, T. T. A. G. (2017) about the importance of accessable interfaces to Māori users.

Task 2 v2: Exploring Tikanga and mātauranga Māori

Worksheet 2.1

Work through this worksheet as you read the resources on Mātauranga Māori

For neurodiverse students it may be useful to use a text to speech tool such as Read Aloud. Please note that this software has some issues pronouncing Māori words which itself could be failing in some aspects of Mātauranga Māori.

The old version of this worksheet.

CS Field Guide

This field guide is written to support students in Aotearoa | New Zealand to prepare for NCEA assessments, and one aspect of that is to be able to apply usability principles relating to mātāpono Māori - considerations that embed Māori culture.

Task 2.2 v2: Exploring Tikanga and mātauranga Māori

Worksheet 2.2

This worksheet works along side the Excellent Article on Māori language interfaces by Te Taka Keegan. Each paragraph can be used as a lesson starter after the Computer Science Field Guide has been completed.

The old version of this worksheet.

Consider mātāpono Māori to assess the usability of a human-computer interface.

Task 1 Heuristics for HCI - Gathering Examples

Task 5: Finding Neilsens Heuristics on AirNZ

To help with your understanding, make a copy of this g.doc Heuristics for HCI - Gathering examples

Use the AirNz website
Find (write or screen capture) an example and explain how this is an example of the heuristic on the g.doc

If you need some clarification, refer back to the slides, CS Field Guide, or your notes

Task 2 Heuristics for HCI - In Reverse

Task 6: Nielsen's Heuristics and Consistency

Now you are an expert, make a copy of this g.doc Heuristics for HCI - In Reverse

Find examples (Write or screen capture) on the Woolworths Online website and work out which heuristic this does/does not meet and explain.
Then compare and contrast the internal and external consistency with New World Online

Task 8: Confusing Terms

Task 8: Confusing terms

People often confuse the following heuristics, make sure you know the difference:

“Error Prevention and Help” with “Users Recognise, Diagnose, and Recover from Errors”
- Help Users Recognise, Diagnose, and Recover from Errors will often be marked in RED. An error has happened and the user is informed.
- Error Prevention will often be highlighted in GREY to show you cannot interact with them. This will prevent the user from ever entering a state in which an error can occur.
“Flexibility and Efficiency of Use” and “User Control and Freedom”
- Flexibility and Efficiency of Use is about being able to do stuff lots of different ways. Look for filters, shortcuts (possibly keyboard), personalisation options.
- User Control and Freedom is about being able to CANCEL, UNDO, REMOVE or GO BACK/RETURN. Look for little red x's, Breadcrumb navigation, or any buttons labeled with the key words above.

My Own Interface

Task 9: Your Own Interface

You will need to study your own interface before the exam. This worksheet will walk you through choosing a good interface along with some examples.

Task 10: Accessibility in Video Games

The website Game Accessibility Guidelines (Link) is a comprehensive, developer-friendly online resource dedicated to helping game creators make their video games more accessible to a wider range of players, including those with disabilities. Each guideline explains why it's important and how it can be implemented, often with examples. These guideline can be applied to a wide range of applications including websites, software, and even physical product interfaces.
