Your touchscreen has an invisible mesh of conductors embedded in it.
The material: Indium tin oxide (ITO)—transparent and conductive.
Grid structure:
Each intersection = potential touch detection point
Test your understanding with this quiz.
Your touchscreen has a 20×15 sensor grid. You touch two opposite corners simultaneously. How many sensors need to report data to locate both touches accurately?
Complete this exercise and get AI-powered feedback.
Grid resolution isn't just about "more is better"—it's about trade-offs. Design for specific contexts.
Think about: Cost, power, precision needs, user capabilities, scale, privacy.
