Scrub video
with a circle.

A patent-pending touch gesture for video navigation. Draw a circle anywhere on the playing video — no progress bar, no on-screen widget, no two-handed grip.

Try It

Press play, then draw a circle anywhere on the video to scrub. Clockwise advances, counterclockwise rewinds. Speed of the circle controls scrub speed.

Demo 1 — Real baseball footage

Press play, then draw a circle anywhere on the picture to scrub. Slow circles step frame-by-frame through a pitch or swing; fast circles fly across innings. The progress bar in the control row never had to move — that’s the point.

How It Works

A free-form rotational gesture, recognized anywhere on the active video surface — without any displayed user-interface control element.

1

Touch anywhere

Place a finger anywhere on the playing video. No target zone required.

2

Draw a circle

Move your finger in a rotational path directly over the active video.

3

Direction = control

Clockwise advances. Counterclockwise rewinds. Natural and instant.

4

Speed = rate

Angular velocity maps to scrub speed — frame-by-frame to rapid scan.

5

Lift to resume

Remove your finger and playback resumes from the new position.

Why a Circle?

Every smartphone and tablet on the planet uses the same video navigation method: a tiny progress bar at the bottom of the screen. It has fundamental ergonomic and precision limits.

Linear progress bar

  • Anchored to bottom edge — outside thumb's reach on large devices
  • Disappears during playback; requires a preliminary tap to reveal
  • Precision degrades as video duration increases
  • Burns screen real-estate during navigation
  • No proportional speed control without separate buttons

Digi-Jog gesture

  • Works anywhere on the screen — one thumb, any grip
  • Performs directly on the active video; no UI to reveal
  • Frame-accurate at low gesture speed; rapid at high speed
  • Zero on-screen chrome required during scrubbing
  • Continuous, gesture-velocity-proportional rate

Where It Fits

Digi-Jog is purpose-built for any application where users scrub long-form video on a touch device. The strongest fits, prioritized:

⌖

Security & surveillance review

Investigators scrubbing through hours of camera footage on tablets. Frame-accurate review, no chrome consumed.

▶

Sports performance analysis

Coaches reviewing plays on the sideline, one-handed, in seconds. Frame-by-frame breakdown without two-handed grips.

▢

Mobile video editing

Touch-first editors gain a precision scrub gesture that feels native — no progress bar contention with track UI.

◈

Fleet & dashcam review

Safety managers reviewing incident footage on iPads. Faster scrub means lower minutes-per-incident.

◐

Drone & capture review

Pilots finding the perfect shot in long aerial captures, on the same device that controls the drone.

●

Body-cam evidence

Officers reviewing long-form body-camera footage. Less chrome, more screen, more efficient review.
