1. What is the core technologies?Resistive (pressure-based contact) and Capacitive (electrical field disturbance)
2. What is the societal impact?Enabled the mobile computing era, democratized technology access, and revolutionized user interfaces
3. How do resistive touchscreens work?They have two flexible layers that touch when you press, completing a circuit and telling the device where you touched.
4. How do capacitive touchscreens work?They use a special layer that feels the tiny electrical pull from your finger, changing a field so the device knows where you touch.

Human-Computer Interaction (HCI): The study of how people interact with computers and digital devices.
Multi-touch: The ability of a touchscreen to recognize and respond to multiple points of contact simultaneously.
Haptic Feedback: Technology that provides tactile sensations to the user, simulating touch or physical responses.
