Introducing Core Haptics
Description: Core Haptics lets you design fully customized haptic patterns with synchronized audio. See examples of how haptics and audio enables you to create a greater sense of immersion in your app or game. Learn how to create, play back, and share content, and where Core Haptics fits in with other audio and vibration APIs.
CoreHaptics is a new framework in iOS 13.
It’s an event based audio and haptic rendering API for iPhone (in short, a synthesizer).
Compatible with iPhone 8 or later.
CoreHaptics is not a replacement of
UIFeebackGenerator, Apple suggests to keep using it for
UIKit controls, reactions, and similar.
We can have a tight connection between audio and haptic.
This has been heavily used internally at Apple for the following applications:
(Yes, all of them have sound!).
This framework is very important for games:
- for boosting feeling
- simulate physical contact (think of a tennis game, every time the racket hits the ball)
- Content classes represent the content itself.
- Playback classes play the content.
The basic, indivisible content element.
Each element has a time (period), a type, and, optionally, some parameters.
Multiple Haptic events can overlap, the outcome will be a mix of all of them.
- Haptic Transient: momentary and instantaneous
- Haptic Continuos/Audio Continuos: lasts longer than transient type, with more parameters to toggle
- AudioCustom: we provide the audio to be played in sync with other haptic types
CHHApticEvents, are then grouped into Haptic Patterns,
AHAP (Apple Haptic Audio Pattern)
- New file format which describes a (Haptic) pattern as text.
- It uses JSON.
- Can be used with Swift Codable.
