Schedule Time & Gather Materials
- Per Test: 5 minutes or less
- Number of Tests: 10 – 20
- Printouts of the page to be tested
- Yellow highlighters
Carry Out This Method
- Print out the page you want to test for visual affordance.
- Give each test participant a printout and a highlighter.
- Ask participants to highlight objects that are clickable.
- Collect results and look for patterns. If any interactive elements are rarely highlighted, or if any non-interactive elements appear interactive to most participants, make note of that.
Try These Tips
- Lab tests can begin with a Blink Test, then a Visual Affordance Test, and then an Expectation Test before you begin a scenario-based Think-Aloud Test.
- You can perform the test with an online version of your design, but have them point at the screen with their finger to respond. Do not allow users control of the mouse, since hover states and pointers may reveal interactivity.
- These tests are quick, and therefore work well as Guerrilla Usability Tests.
- Time permitting, follow up by asking users what they expect would happen if they were to click on the elements they marked as interactive.
