Position Your Device

Place a laptop or tablet on a table or chair at roughly hip height. The camera needs a clear front-on view of the student from head to toe — the full arm swing and foot spread must both be visible. Leave enough space on either side for the arms to reach out wide.

💡 Landscape orientation only

Wait for Pose Engine & Check the Skeleton

After opening the tool and allowing camera access, wait for ● POSE ONLINE to appear in the header. A white skeleton will appear over the student’s body confirming they are being detected. The READY button unlocks automatically.

💡 First load takes ~10–15 seconds

Student Gets in Starting Position

The student stands on the foot guide shown on screen, facing the camera with feet together and arms at their sides. Their full body from feet to raised hands must be visible — this is the starting position for a jumping jack.

💡 6–8 feet from camera works well for most students

Press READY & Go on Cue

Press the READY button to start the 3-2-1 countdown. On GO! the student begins jumping jacks. The tool records and analyses 10 seconds of movement, updating the rep counter and form feedback after every completed rep.

💡 Students can press READY themselves once they know the routine

Review the Replay & Rep History

After 10 seconds the video plays back at 50% speed automatically. The side panel shows the final good rep count, total reps, and a dot for every rep. Students can use the history dots to identify where form broke down — typically the last few reps as they tire.

💡 Press TRY AGAIN to immediately attempt another set and try to beat the score

Position Your Device Side-On

Place a laptop or tablet on a chair or table at roughly hip height, positioned so the student will be sideways to the camera. This angle is essential — front-on does not show the back leg lift or forward hinge properly. The student’s whole body, from head to raised foot, must fit in the frame.

💡 Side-on camera angle is critical for this tool

Clear Floor Space

Leave about 6 feet of open space around the student — the back leg extends well behind them and the forward hinge brings the upper body forward. Crash mats or gym mats under the student are a good idea for students who may wobble out of the hold.

💡 Soft surface underneath helps with confidence

Wait for Pose Engine & Pick a Difficulty

Wait for ● POSE ONLINE to appear in the header and the skeleton overlay to show up on the live video. Then tap EASY, MED, or HARD in the header to set the hold-time goal.

💡 Difficulty can be changed between students with one tap

Student Gets Into Starting Position

The student stands sideways on two feet, facing across the camera’s view. They can choose either leg as their standing leg — the tool auto-detects which leg is lifted and adjusts the checks accordingly. Arms can be out to the sides or forward, whatever feels most balanced.

💡 Arm position is not checked — any comfortable position is fine

Press READY & Hold on Cue

Press READY to start the countdown. On GO! the student lifts one leg behind into a scale. A hold timer appears on the video — it counts up while all four checks are passing and resets to 0 if form breaks. Students have a 15-second window to achieve their best hold.

💡 Wobbles are fine — just reset the pose and keep trying for a best time

Review the Replay & Best Hold

After 15 seconds the video plays back at 50% speed automatically. The side panel shows the best hold time achieved. The slow-motion replay makes it easy to spot exactly when form broke — a bent standing leg, a dropping back leg, or a lifted torso.

💡 Press TRY AGAIN to immediately attempt another hold

Position Your Device

Set a laptop or tablet on a table or chair at roughly hip-to-chest height. The camera needs a clear side-on view of the thrower from head to toe — side-on is essential so the arm cock, elbow height, and follow-through are all visible. Avoid placing the device directly in the ball’s flight path.

💡 Landscape orientation only

Set the Throwing Arm

Before the first student steps up, tap RIGHT or LEFT in the header to match their throwing hand. The on-screen skeleton will highlight the correct arm in cyan so you can confirm it’s tracking the right side.

💡 Change this between students — it takes one tap

Wait for Pose Engine & Check the Skeleton

After opening the tool and allowing camera access, wait for ● POSE ONLINE to appear in the header. You’ll then see a white skeleton overlaid on the student’s body — this confirms they are being detected. The READY button unlocks automatically once the engine is live.

💡 First load takes ~10–15 seconds

Student Gets in Position

The student stands sideways to the camera — throwing shoulder closest to the lens — on the foot guide shown on screen. Their full body from feet to raised hand should be visible. The guide disappears once the assessment starts.

💡 6–8 feet from camera works well for most students

Press READY & Throw on Cue

Press the READY button to begin the 3-2-1 countdown with audio beeps. On GO! the student performs an overhand throw. The tool records 4 seconds of movement from that moment — no ball is needed, the motion alone is assessed.

💡 No ball required — the throwing motion is all that matters

Review the Instant Replay

The video plays back at 50% speed automatically. The checklist shows each element as green ✓ or red ✗. Each check requires 5 consecutive frames of correct form — a brief flash of good position won’t trigger a tick, encouraging students to hold their technique throughout the movement.

💡 Press TRY AGAIN to immediately attempt another rep

Open the Scoreboard on the Projector

Connect a laptop to your projector or wall-mounted TV. Open Cosmic Bowling — a unique room code and QR appear in the bottom-right corner. Use the toolbar to set your alley name, edit the I Can statement, and add or remove lanes to match your class size.

💡 Reset All Scores starts fresh without losing the roster

Position Your Device

Place a laptop or tablet on a chair, table, or stand at about player hip-to-chest height. The camera should capture the player from head to toe with enough space to see the passing platform clearly.

Wait for Pose Engine

After opening the tool and allowing camera access, wait for the ● POSE ONLINE indicator to appear in the top header. This confirms MediaPipe has loaded and is tracking landmarks correctly. The READY button unlocks automatically.

Player Gets in Frame

The player stands on the foot guide shown on screen, facing the camera. Their full body should be visible, including both feet and both arms forming the platform. The guide disappears once the assessment begins.

Press READY & Toss on Cue

Player or teacher presses READY. A 3-2-1 countdown begins with sound cues. On TOSS! the partner tosses the ball and the player performs the forearm pass. The tool records 4.5 seconds from that moment.

Review the Instant Replay

After the recording ends, the replay automatically runs at 50% speed. The checklist panel shows which passing skills were detected. Each skill must appear for 4 consecutive frames, so a lucky moment will not earn a check by itself.

Position Your Device

Place a laptop or tablet on a table or chair at roughly player hip-to-chest height. The camera should have a clear view of the player from head to toe. A side-on or slight angle works best — avoid directly behind or in front of the ball path.

Wait for Pose Engine

After opening the tool and allowing camera access, wait for the ● POSE ONLINE indicator to appear in the top header. This confirms MediaPipe has loaded and is actively detecting body landmarks. The READY button will unlock automatically.

Player Gets in Frame

The player stands on the foot guide shown on screen, facing the camera. Their full body — feet to hands raised overhead — should be visible. The foot guide disappears once the assessment starts.

Press READY & Toss on Cue

Player (or teacher) presses the READY button. A 3-2-1 countdown begins with audio beeps. On TOSS! the partner tosses the ball and the player sets. The tool records 4.5 seconds from that moment.

Review the Instant Replay

After recording, the video plays back automatically at 50% speed. The checklist on the right shows each skill as green ✓ or red ✗. Each check requires 4 consecutive frames of good form — so a flash or fluke won’t earn a tick.
