What is usability testing?

00:10.000 --> 00:13.000
Methods of usability testing.

00:13.000 --> 00:15.000
Hello everyone.

00:15.000 --> 00:19.000
We are exploring an exciting aspect of UI and UX design.

00:19.000 --> 00:22.000
Usability testing and refinement.

00:22.000 --> 00:26.000
Have you ever used an app or website that felt confusing?

00:26.000 --> 00:28.000
Did the buttons were hard to find?

00:28.000 --> 00:30.000
Or the text was too small?

00:30.000 --> 00:36.000
Well, usability testing helps designers fix those problems.

00:36.000 --> 00:39.000
What is usability testing?

00:39.000 --> 00:46.000
Usability testing is when we check if a website, app, or program is easy to use.

00:46.000 --> 00:51.000
We do this by watching real users try it out and noting their experience.

00:51.000 --> 00:57.000
If they struggle, we make changes to improve it.

00:57.000 --> 01:00.000
There are different ways to test usability.

01:00.000 --> 01:03.000
AB testing and user observation.

01:03.000 --> 01:05.000
Improving a school learning app.

01:05.000 --> 01:08.000
A school is launching a new homework submission app,

01:08.000 --> 01:12.000
and they want to make sure students can easily find the submit button.

01:12.000 --> 01:14.000
Step 1.

01:14.000 --> 01:16.000
AB testing.

01:16.000 --> 01:20.000
The designers create two versions of the submission page.

01:20.000 --> 01:25.000
Version A. The submit button is blue and at the top of the page.

01:25.000 --> 01:31.000
Version B. The submit button is red and centered on the page.

01:31.000 --> 01:34.000
They divide students into two groups.

01:34.000 --> 01:40.000
Group 1 uses version A. Group 2 uses version B.

01:40.000 --> 01:47.000
After testing, they find that version B, red button, center of the page gets more clicks.

01:47.000 --> 01:49.000
Step 2.

01:49.000 --> 01:51.000
User observation.

01:51.000 --> 01:57.000
Even though version B gets better results, the designers watch students using the app and notice some problems.

01:57.000 --> 02:00.000
One student still struggle to find the button.

02:00.000 --> 02:04.000
Others accidentally close the app while searching for help.

02:04.000 --> 02:06.000
One student asks,

02:06.000 --> 02:11.000
How do I know if my homework is submitted?

02:11.000 --> 02:15.000
Does the app clearly show a confirmation when homework is submitted?

02:15.000 --> 02:17.000
No.

02:17.000 --> 02:20.000
Refining designs based on feedback.

02:20.000 --> 02:26.000
Based on these observations and AB test results, the designers make changes.

02:26.000 --> 02:32.000
Keep the red button in the center since it performed best in AB testing.

02:32.000 --> 02:38.000
Add a help icon near the button for confused students.

02:38.000 --> 02:47.000
Make the button bigger and add a confirmation message after submission.

02:47.000 --> 02:53.000
Remember, usability testing helps create better user-friendly designs.

02:53.000 --> 03:00.000
Keep testing, keep refining, and keep making awesome digital experiences.
