White Paper on 10-Point Nano Touch Technology: Multi-User Writing & Gesture Operations
1. Technical Architecture
The Nano Blackboard employs 4th-gen nano-capacitive technology with groundbreaking "Grid+Self-Capacitance" dual-mode detection, delivering industry-leading performance:
1.Nanoscale Precision:
0.5μm ITO grid enables 65535×65535 resolution
±0.2mm positioning accuracy (industry avg. ±1mm)
256-level pressure sensing (5-500g detection)
2.Interference Immunity:
EMI shielding withstands 30V/m RF interference (EN 55032 Class B)
Oleophobic coating (＞110° water contact angle)
Dynamic filtering eliminates 80dB ambient noise
3.Optical Excellence:
OCA lamination achieves 93% transmittance
178° viewing angle with 98% edge-touch consistency
0.3mm ultra-thin design eliminates writing parallax
2. Multi-User Interaction
2.1 Smart Zoning:
Auto user-position detection with dynamic area allocation
Role-based controls:
Teachers: Override/edit any student zone
Students: Group competition mode with scoring
Data fusion: Export collaborative work as PDF/PPT

2.2 Advanced Algorithms

Technology	Principle	Educational Value
Stroke Prediction	LSTM neural network	Reduces latency to 6ms
Multi-modal Fusion	Capacitive+IR dual verification	0.01% false-touch rate
Pressure-Gradient	Auto line weight/opacity	Calligraphy effects
