Nielsen’s 10 Usability Heuristics evaluations and identifying heuristics violations
Introduction About me - background with HCI ● ● HCI/usability in educational software ○ Game based and gamified language learning ○ Programming education Ph. D research ○ Industry partnership ○ Online learning platform ○ Adaptive and differentiated learning
Lab Outline ● Introduction ● Review heuristics & definitions ○ Quick interactive activity ● Examples in various interfaces ○ Assignment 1 preparation ● Practice heuristics evaluation - quizmaker ○ Goal oriented evaluation
Learning Outcomes ● Be able to carry out a basic heuristics evaluation of an interface ○ Be able to identify usability issues in interfaces ○ Be able to relate usability issues to heuristics violations ○ Be able to explain how usability is affected by heuristics violations This is a key part of Assignment 1. . .
The 10 Heuristics with Explanations
Review of heuristics & definitions Goal: Revise heuristics and definitions
Kahoot! and Usability How much of Kahoot!’s success is due to usability?
Background Based on analysis of many more specific examples of usability issues that have been observed. Nielsen, J. (1994, April). Enhancing the explanatory power of usability heuristics. In Proceedings of the SIGCHI conference on Human Factors in Computing Systems (pp. 152 -158). ACM.
Good usability Some interfaces have extremely good usability. If you use the vending machines on campus pay attention why they are so usable. Does anyone know of vending machines that are more difficult to use than the ones on campus?
Viewing Examples of Heuristics Violations The next slides will show examples of heuristics violations. We will talk about why usability is affected and what heuristics have been violated.
Can you see any issues?
How can I see more routes and options?
Is anything ambiguous?
How can the user change their attendance status?
Can you see it now?
If you wanted to find more courses where would you look?
All tasks seem to be complete, why can’t the user click ‘Up Next’?
Take note of the solution button…
What problem could be created in this version…
How would you navigate this site?
What major error could happen here? Detailed blog post about this here: https: //developmentality. wordpress. com/2013/02/05/slips-vs-mistakes-what-wordpress-gets-wrongthat-blogger-and-tumblr-get-right/
Cost of early release. . .
Has the user fixed the error?
Are these questions saved?
Practice Heuristics Evaluation Look for specific problems with heuristics in goconqr. com 1. 2. 3. 4. 5. 6. Go to → www. goconqr. com Sign-up Create a multi question quiz Run your quiz Go back to the homepage Try to find where your quizzes are
Alternative Quiz Website A simpler and older quiz maker website; can be used if there are problems with the first one or as an extra example. Go to → http: //www. webwinder. com/ww_stm_quiz. php tinyurl. com/2 bybfuq Or google ‘webwinder quiz’
It can get worse. . . Google ‘the slide rule universe’ or go to: http: //www. sphere. bc. ca/test/sru niverse. html
Tips for Assignment 1 For each heuristic problem you find: ● List the heuristic problem ● Describe how the heuristic is violated ● Clearly communicate how it affects usability
