# OpenMultitouchSupport

This enables you easily to observe global multitouch events on the trackpad (Built-In only).  

I created this library to make MultitouchSupport.framework (Private Framework) easy to use.

## References

This library refers the following frameworks very much. Special Thanks!

- [mhuusko5/M5MultitouchSupport](https://github.com/mhuusko5/M5MultitouchSupport)

- [calftrail/Touch](https://github.com/calftrail/Touch/blob/master/TouchSynthesis/MultitouchSupport.h)

## Requirements

- Development with Xcode 15.2+

- swift-tools-version: 5.9

- Compatible with macOS 12.0+

## Demo



## Build OpenMultitouchSupportXCF.xcframework

```sh

$ sh build_framework.sh

```

## Usage

App SandBox must be disabled to use OpenMultitouchSupport.

```swift

import OpenMultitouchSupport

import Combine

var cancellables = Set()

let manager = OMSManager.shared()

manager.touchDataPublisher

    .sink { touchData in

        // ・・・

    }

    .store(in: &cancellables)

manager.startListening()

manager.stopListening()

```

### The data you can get are as follows

```swift

struct OMSPosition {

    var x: Float

    var y: Float

}

struct OMSAxis {

    var major: Float

    var minor: Float

}

enum OMSState: String {

    case notTouching

    case starting

    case hovering

    case making

    case touching

    case breaking

    case lingering

    case leaving

}

struct OMSTouchData {

    var id: Int32

    var position: OMSPosition

    var total: Float // total value of capacitance

    var pressure: Float

    var axis: OMSAxis

    var angle: Float // finger angle

    var density: Float // area density of capacitance

    var state: OMSState

    var timestamp: String

}

```
