Marking pattern

Most scanning patterns describe a path the eye travels. This one describes the eye refusing to travel at all. The reader parks their gaze at a fixed point on the screen, usually a little above centre, and scrolls the content through it, the way you might hold a finger on a line while dragging a page under it. Nielsen Norman Group recorded it as the marking pattern and found it mostly on phones, where the thumb is already doing the moving and where a small screen makes holding one spot cheaper than searching a large one.

Design consequences follow from the fact that the screen now has a hot band rather than a hot corner. Content is judged as it passes through that band, in the width of a phone and in a fraction of a second, which is why a feed item has to identify itself in its first line and why a heading that needs the paragraph under it to make sense will be scrolled past unread. It also explains an ordinary frustration with sticky elements: a sticky header or a floating promotion parked in the upper third of a phone screen is sitting exactly where the gaze is held, so it does not get glanced at, it gets scrolled through, over and over.

The pattern says nothing about the reader being careless. Marking is efficient, and it is how people triage a long list: hold the point, stream the candidates, stop when something matches. The layout job is to make each passing item resolvable on its own, which usually means a strong first line, a consistent left edge for names and numbers so the held point lands on the same column every time, and no important distinction that only shows up in an item’s second half.

One name collision is worth stating plainly, because the words are almost identical and the concepts are unrelated. The marking pattern is an eye tracking finding about where the gaze rests. A marking menu is an interaction control: a radial menu whose items are selected with a directional gesture. Nothing in this entry is about gestures, and nothing in that one is about eyes.
