GESTEN-KINEMATIK & ABTASTSTABILITÄT
Wischgesten-Kinematik, Geschwindigkeitsableitung & Zeitstempel-Jitter
Die Reaktionsfähigkeit hängt von hochfrequenten Abtastraten (120Hz bis 360Hz) und präzisen Zeitintervallen (Δt) ab. Geschwindigkeit (v) und Beschleunigung (a) werden aus den Koordinatendifferenzen abgeleitet:
KINEMATISCHE ABLEITUNG
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.
