TypeFlow Eye + Replay Studio

Eye tracking and keystroke logging, replayed together

This example was recorded with TypeFlow Eye, which synchronizes webcam-based eye tracking with keystroke logging. Replay Studio then reconstructs the session so gaze, pauses, revisions and the evolving text can be examined in sequence.

Latest release

TypeFlow Research Suite V35 What’s new

Eye Engine 0.3.13 · Replay V35

12 SEPTEMBER 2026

One suite across writing environments: Core, Multi and Slides now share the same Eye data pipeline and research definitions while preserving the layout, objects and analytical context specific to each writing environment.
More consistent Eye capture: Eye Engine 0.3.13 strengthens frame, camera-timing and coordinate integrity. Raw samples and all calculable gaze, fixation, inter-fixation transition and AOI results remain available for later review.
Non-intrusive validation: Eye sessions use calibration and immediate validation before writing, followed by an optional post-task validation. No scheduled mid-session check interrupts the writing process.
Transparent quality evidence: Core, Multi and Slides report comparable evidence on sampling, missing data, off-screen gaze, tracking loss, reacquisition and spatial validation, with explicit denominators and exact provider, engine and model provenance. Low quality is reported without deleting recorded data or calculable results.
More reliable Replay: Replay reads the new quality evidence, remains compatible with earlier workbooks and improves the reconstruction of revisions and multilingual text, including Chinese, Japanese and Korean input.
Research status: TypeFlow Eye remains an experimental webcam-based research system. It has not yet been validated against a reference eye tracker, so researchers should pilot it in their target setting, report the exact version used and retain the exported quality evidence.

Research

Method and data outputs

TypeFlow records event traces for temporal analysis of writing processes without local installation.

What keystroke logging adds

Unlike static text snapshots, keystroke logging captures writing in motion: onset, pause distribution, revision timing, and focus transitions. This provides trace-level evidence for process models and intervention studies.

Temporal precision

Timestamped events support pause and burst analysis.

Revision visibility

Insertion/deletion behavior becomes analytically explicit.

Scalable outputs

Workbook structure supports cohort aggregation.

Workbook outputs

Event stream Keystrokes, pauses, mouse actions, and focus events with timing data.

Derived measures Bursts, revisions, diagnostics, and aggregate indicators.

Final text Participant output stored alongside process traces.

Session metadata Device, timing context, and app variant for reproducibility.

Scope note: in standard apps, TypeFlow does not record full-screen video. Audio is only captured in TypeFlow Speak sessions.

Reporting checklist

Task constraints and writing prompts.
Device and browser conditions.
Pause thresholds and derived metrics.
Data cleaning and exclusion criteria.

Ethics reminders

Inform participants what is logged (keystrokes and interaction traces), what is not logged, and where outputs are stored.

Quick quality checks

Use Replay Studio and Workbook Merger to detect missing focus segments, unusual bursts, and export anomalies.

Training

Run consistent sessions

Operational guidance for pilots, classrooms and controlled data collection.

Session checklist

1

Before

Verify keyboard, browser, consent, and clear task instructions.

2

During

Reduce tab switching, keep the same device, avoid copy-paste interventions.

3

After

Open workbook, check final text length, archive with consistent naming.

Pilot recommendation

Run a 2-minute trial first and inspect it in Replay Studio before the full session.

Frequently asked questions

Practical answers for pilots and active data collection.

Do participants need to install anything?

No. TypeFlow runs in the browser. A physical keyboard is required for clean keystroke logging.

Does TypeFlow record audio or the full screen?

No screen recording. In standard apps, audio is not recorded either. In TypeFlow Speak sessions, audio is recorded for transcription-based research.

Can students use tablets or iPads?

Yes, but run a short pilot first. Use a physical keyboard and verify that key events are captured correctly.

How do I check that an export is valid?

Open the workbook, verify the final text, and inspect the session in Replay Studio to identify anomalies.

Can I merge files from different app versions?

Yes. You can merge workbooks using Workbook Merger Pro.

Is internet required?

Yes, TypeFlow is web-based. If you need an offline export-only setup, contact the author.

Where are the files stored?

Exports are stored locally on the participant device. In email mode, files can be sent by email. A backup copy is created on the TypeFlow server and deleted after one month.
