Device is portrait mode. Be sure to run your device so the longer dimension is horizontal. That is, it should be wider than it is tall, also called “Landscape” orientation—sideways for phones.

This experiment includes two different sets of scrolling tests. Each set of scrolling tests has 10 pages—20 pages in total.

• The first scrolling test is designed for when you do not know where the target is. You need to scroll down and find it.
• The second scrolling test simulates when you do know where the target is.

The experiment starts with two practice pages, one of each scrolling test type.

There is no break between pages. Begin scrolling as soon as each page loads.

Performance timing will be shown at the end of the experiment. Timing data are stored in cookies, so ensure that cookies are enabled.
