By calibrating the recording space and standardizing multi-camera placement, video capture becomes a structured data acquisition system rather than simple footage.

A visual–numerical approach to running speed assessment of cycle trajectories, showing how stride trajectory curves and phase-based metrics enable more precise evaluation of running speed and technique.

Presents a color-coded methodology for visualizing running stride trajectories, enabling precise phase differentiation and systematic evaluation of each segment of the running cycle.

This blog focuses on analyzing ball flight and target accuracy using digital assessment and visual tools to support learning and coaching in youth soccer.

An approach to assessing kicking technique focused on the moment of ball–foot contact, using visualizations to turn an abstract concept into something students can see, understand, and learn from.

This approach visualizes key factors that characterize quality ball-striking performance and identifies potential in young players.

Stride length goes beyond step distance, observing it is key to running speed and movement efficiency.

Explore how ground friction shapes running technique, showing its dual role in slowing the body on contact and propelling it forward.
