VeloS Band

VeloS Band was built to provide a simple wearable way to estimate swing speed from arm motion and display the result directly to the user.

Measuring swing speed usually requires external sensors, cameras, or dedicated training tools. This project explored a compact wearable alternative.

The device uses embedded hardware and motion-sensing logic to detect swing movement, process the motion data, and present a readable speed result.

Wearable Form Factor

• Designed around a wrist-worn device concept
• Focused on portability and quick use during motion
• Built for direct user feedback without needing an external display

Motion Detection

• Tracks arm movement during a swing
• Uses motion samples over time instead of a single instant reading
• Supports swing-speed estimation from changing motion data

Speed Calculation

• Processes sensor data into a speed estimate
• Focuses on identifying the meaningful part of the swing
• Displays a final speed value to the user

Embedded Interface

• Uses onboard controls for recording and interaction
• Displays device states and results
• Supports a simple calibration and recording workflow

The device establishes a starting reference before recording motion.

The system captures motion data during the forward swing movement.

Motion samples are interpreted to estimate the user’s arm speed.

The final speed result is shown directly on the wearable device.
