Multi-touch technology

Definition

Multi-touch technology allows users to interact with a device's interface by using multiple fingers or touch points simultaneously. This form of input enhances user experience by enabling gestures like pinch-to-zoom, swipe, and rotate, which mimic natural interactions and make navigation more intuitive and fluid.
