GESTURE KINEMATICS & SAMPLING STABILITY
Touch Flick Kinematics, Velocity Derivation & Timestamp Jitter
Touch gesture tracking performance depends on high-frequency sampling (120Hz to 360Hz digitizer polling) combined with low-variance timestamp intervals (\(\Delta t\)). Velocity (\(v\)) and acceleration (\(a\)) are derived from continuous spatial coordinate deltas:
KINEMATICS DERIVATION
v(t) = √( (Δx/Δt)² + (Δy/Δt)² )
a(t) = ( v(t) - v(t-1) ) / Δt
OPTOMETRIC ERGONOMICS & NON-MEDICAL NOTICE
Monitor Test Hub is an engineering calibration utility for electronic visual displays (LCD, OLED, QD-OLED, MicroLED) and mobile touch digitizers. This software is NOT a medical eye exam, optometric vision test, or diagnostic health utility.
To reduce Digital Eye Strain (DES) during display calibration, apply optometric ergonomics:
- The 20-20-20 Rule: Every 20 minutes, look at an object at least 20 feet away for 20 seconds.
- Ambient Illumination: Ensure room ambient lighting matches display brightness levels (~100–150 nits for standard SDR workloads).
- Optimal Viewing Distance: Place your screen approximately 20 to 30 inches (50–75 cm) from your eyes.
