CINÉMATIQUE DES GESTES & STABILITÉ
Cinématique de Balayage, Dérivation de Vitesse et Gigue Temporelle
La réactivité tactile repose sur un balayage haute fréquence (120Hz à 360Hz) associé à de faibles variations temporelles (Δt). Vitesse (v) et accélération (a) sont déduites des écarts de coordonnées continues :
DÉRIVATION CINÉMATIQUE
v(t) = √( (Δx/Δt)² + (Δy/Δt)² )
a(t) = ( v(t) - v(t-1) ) / Δt
OPTOMETRIC ERGONOMICS & NON-MEDICAL NOTICE
Display Test Online 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.
