Touchscreen technology has evolved from early resistive screens, which required pressure, to sophisticated capacitive screens that detect human touch through electrical signals. This advancement has improved sensitivity, clarity, and multi-touch functionality, creating more intuitive user interfaces. Today's high-definition displays are common in smartphones, tablets, and various devices, and touchscreens are now integrated into everyday appliances and self-service kiosks. Innovations such as haptic feedback, flexible screens, and enhanced gesture recognition have further enhanced the technology, making it more responsive, versatile, and user-friendly, and transforming our interaction with devices.
