Scrolls are a series of pages that participants and designers can flip through together, progressing through various screen interface concepts. This prototype method is especially effective in the early stages of product development, before the final design, because you can get feedback on multiple concepts that would otherwise be expensive to build in higher fidelity.
Before you create your scroll, you should first determine clear goals. What do you wish to learn from testing? For example, you might want to see whether your test participants can find a particular button or if the button function is obvious. Once you’ve determined what you’re after, try to think of your product steps from the user’s perspective. Then convert your task into a journey that you and your participants can work through together.
To create the scroll, print your product journey with one page for every step and add numbers to each page. Then tape the print-outs end-to-end in corresponding order. Now roll up the pages and you’ve created a single, long-panel scroll.
When testing, be sure to explain the scenario to the participant and let them control the pace by unrolling the scroll themselves. As the participant moves through the scroll, ask them to narrate what they think is happening on each page. If they seem confused, or pause for any reason during a test, ask questions and figure out the cause.
