Évaluation Technique et Théorie de Calibration Tactile

Les numériseurs capacitifs détectent les contacts via les variations de charge sur une matrice de capteurs. Des micro-fractures ou saturations de contrôleur engendrent zones mortes, sautillements ou dérives de trajectoire.

Le moteur Touch Matrix analyse l'intégrité du panneau selon trois axes essentiels :

  • Isolation des Zones Mortes : Le balayage identifie les cellules actives. Les zones non touchées sont isolées comme blocs inactifs.
  • Télémetrie de Gigue et Vitesse : Mesure la régularité d'échantillonnage et les intervalles de trame. Une gigue élevée signale une instabilité du contrôleur.
  • Dérive de Trajectoire : Calcule l'écart RMS entre le tracé réel et la trajectoire idéale pour détecter toute distorsion.

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.
Technical FAQs & Helpful Content

Perguntas Frequentes (FAQ)

Tudo o que você precisa saber sobre este instrumento de diagnóstico, procedimentos de calibração e normas técnicas.

01.What is the Touch Matrix Suite?
The Touch Matrix Suite is a comprehensive hardware diagnostic tool for auditing touch digitizer health, active cell matrix coverage, gesture velocity tracking (px/ms), timestamp jitter, and vector drift error.
02.What hardware device presets are available in Touch Matrix?
Touch Matrix provides specialized presets for Smartphones, Tablets, Convertible Laptops, and Interactive Touch Monitors with tailored grid resolutions.
03.What is grid density (Coarse, Medium, Fine) in touch matrix testing?
Grid density controls the cell resolution of the test overlay. Coarse (5x5) tests quick gesture coverage, Medium (10x10) provides standard verification, and Fine (20x20) inspects sub-millimeter dead zones.
04.How does the W3C PointerEvents API capture touch telemetry?
PointerEvents captures raw hardware events from capacitive digitizers, exposing pointerId, clientX/Y coordinates, pressure, width/height radius, and sub-millisecond timestamps.
05.What is timestamp jitter in digitizer sampling?
Timestamp jitter measures the standard deviation (σ) of time deltas between incoming touch events. Low jitter indicates smooth, consistent hardware polling.
06.What causes vector trajectory drift on touch screens?
Vector trajectory drift is non-linear deviation between a finger's physical motion and the digitizer's reported coordinates, usually caused by non-uniform ITO sensor impedance or EMI.
07.Can I run Touch Matrix diagnostics on drawing tablets?
Yes! Touch Matrix supports both finger touch and active stylus pens (Wacom, Apple Pencil, Surface Pen).
08.How do I switch between Dead-Zone, Multi-Touch, and Vector test modes?
Use the mode buttons inside the Touch Matrix Tester component or use the 'M' hotkey to cycle diagnostic modes.
09.What is a good Digitizer Health Index score?
A score of 95–100 indicates perfect capacitive digitizer health with 100% matrix coverage, sub-millisecond jitter, and zero dead zones.
10.How do I enter fullscreen mode for touch matrix testing?
Press the 'F' key or tap the 'FULLSCREEN' button to expand the touch matrix canvas across your entire screen.
