Frame by Frame
Pacing studies for digital reading
A study of how paragraph timing — line length, leading, scroll cadence — shifts comprehension and dwell time in long-form reading interfaces.
The question
If reading is paced like film is paced — frames per second, beats per shot — what happens when we treat scroll as a timing instrument rather than a navigation tool?
Method
We ran a [N]-participant within-subjects study comparing [three or four reading conditions]. Each participant read [text source] under each condition and answered a comprehension survey, then a self-report on attention.
Conditions
- Baseline — standard scroll, default leading.
- Paced — scroll velocity capped at a “reading speed” the system inferred from the first two paragraphs.
- Frame-by-frame — text revealed in fixed beats, like subtitles.
Findings
- Comprehension was [comparable / higher / lower] under “paced” — the win was smaller than expected but consistent.
- Self-reported attention was significantly higher under paced.
- Frame-by-frame felt cinematic in pilot but tested poorly: readers reported feeling “controlled.”
The take: pacing helps when it’s a suggestion, not a constraint.
What I’d build next
A reading mode for long essays that nudges scroll cadence without locking it. A subtitle for the act of reading itself.
