Gaze and scroll position indicate where another person is attending

What it is

Attention awareness uses gaze location, viewport, scroll position, or selection to suggest which region a collaborator may be attending to. It is closer to the task object than an online indicator, but remains behavioral evidence rather than direct access to a mental state. Looking at a paragraph does not prove comprehension, and stopped scrolling may mean absence.

Why it happens

Tightly coordinated partners anticipate what another will discuss or manipulate next. A viewport provides a coarse candidate region, gaze a transient local cue, and selection a more deliberate action cue; their time scales and certainty differ. Combining them can reduce reference repair and duplicated inspection, while precise continuous trails add clutter and privacy exposure.

Studying it

Paired search or analysis tasks can compare no cue, shared viewport, gaze point, and selection on joint localization time, duplicate inspection, referential repair, and accuracy. Eye-tracking studies must report calibration and loss; scrolling can be logged directly. Ground truth for “attention” should combine task relevance and retrospective explanation rather than gaze duration alone.

Where it stops holding

Peripheral vision, reflection, and off-device material are not captured by current gaze. Some eye-tracking and assistive-technology users provide no conventional trail. Displaying precise gaze can itself alter looking. In loosely coupled work, coordination benefit may be smaller than distraction and privacy cost.

Applying it

• Default to coarse viewport or object state and reveal precise gaze only during explicit joint work.
• Distinguish viewport, gaze, and selection visually rather than implying equal certainty.
• Make each cue independently controllable and limit audience and retention.
• Test joint localization and independent reading for benefit, distraction, and misinference.
