About SkillDrills
SkillDrills is a browser-based collection of visual tracking and reaction timing exercises.
Open-access browser exercises
SkillDrills is designed for anyone looking to practice visual pursuit, target tracking, and reaction timing directly on their computer, tablet, or mobile screen.
All drills run in standard web browsers with configurable speeds and durations, requiring no specialized hardware or software installations.
Exercise characteristics
- Mathematical trajectories: Sinusoidal waves, Lissajous curves, zig-zag lines, and infinity loops rendered at 60 FPS.
- Millisecond measurement: High-resolution browser timestamps for timing response latency.
- Distraction-free interface: True black canvas viewport with minimal surrounding controls.
