The Taptic Engine is a linear actuator inside Apple Watch that produces haptic feedback
The Taptic Engine is a linear actuator inside Apple Watch that produces haptic feedback. In less technical terms, it taps you on the wrist whenever you receive an alert or notification, or press down on the display. Combined with subtle audio cues from the specially engineered speaker driver, the Taptic Engine creates a discreet, sophisticated, and nuanced experience by engaging more of your senses. It also enables some entirely new, intimate ways for you to communicate with other Apple Watch wearers. You can get someone’s attention with a gentle tap. Or even send something as personal as your heartbeat.
