what is taptic engine

The Taptic Engine is a type of haptic feedback technology used in Apple devices, such as the iPhone 7 and newer models. It uses a linear actuator to produce precise vibrations and tactile experiences that can mimic the sensation of motion or generate new and distinct tactile experiences. The Taptic Engine is designed in-house by Apple, which allows them to optimize it for quick, precise taps and pick resonant frequencies that enhance the user experience. The technology is used to mimic a home button press, relay system notifications, and reinforce audio alerts. The Taptic Engine is much more precise than the older linear actuator used in earlier models, and it gives better feedback with associated actions. The Taptic Engine is also used in other Apple products, such as the Apple Watch. In the future, Apple may include multiple Taptic Engines in their devices to provide physical feedback to users.
