Touchscreen Examples for Grade 1 Computer Science & Technology

📚 Quick Study Guide

🖱️ Touchscreens use physical touch to interact with devices. 💡 Resistive touchscreens react to pressure. They are durable but have lower clarity. ⚡ Capacitive touchscreens use electrical conductivity. They are more sensitive and have better clarity. 📡 Infrared touchscreens use infrared beams. They are commonly used in large displays. 🌊 Surface Acoustic Wave (SAW) touchscreens use sound waves. They provide excellent image clarity and light transmission. 💻 Touchscreens are found in smartphones, tablets, kiosks, and many other devices. ➕ Touchscreen technologies differ in sensitivity, durability, and cost.
