WatchShaker

Simple motion detector for ⌚️ (watchOS) shake gesture.

<img src="https://raw.githubusercontent.com/ezefranca/WatchShaker/master/.utils/bwshaker.jpg" width="400" height="300" /> WatchShaker is a watchOS helper to get your ⌚️ shake movements

This project was presented at ICECCME 2024. The work is available (soon) at IEEE Xplore. You can also find a preprint on Papers with Code.

Requirements

watchOS 7.0+
Xcode 15.0+

Installation

Swift Package Manager

Once you have your Swift package set up, adding WatchShaker as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/ezefranca/WatchShaker.git")
]

Manually

Download and drop WatchShaker folder in your project to your watch target.
Congratulations!

Usage example

@StateObject style

import SwiftUI
import WatchShaker

struct ContentView: View {
    
    @StateObject var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)
    
    var body: some View {
        VStack {
            if shaker.isShakerAvailable {
                Text("I'm shook! ⌚️⌚️⌚️")
                Text("\(shaker.shake.sensibility)")
                Text("\(shaker.shake.direction)")
            }
        }
    }
}

Closure Style

import WatchKit
import Foundation
import WatchShaker

class InterfaceController: WKInterfaceController {
    
    var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)
    
    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
    }
    
    override func willActivate() {
        super.willActivate()
        
        shaker.start()
        
        shaker.startWatchShakerUpdates = { shakeSensibility, error in
            
            guard error == nil else
            {
                print(error?.localizedDescription)
                return
            }
            print("I'm shook! ⌚️⌚️⌚️")
        }
    }
    
    override func didDeactivate() {
        super.didDeactivate()
        shaker.stop()
    }

}

Delegate Style

import WatchKit
import Foundation

class InterfaceController: WKInterfaceController {

    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
        // Configure interface objects here.
    }

    var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)

    override func willActivate() {

        super.willActivate()
        shaker.delegate = self
        shaker.start()
    }

    override func didDeactivate() {

        super.didDeactivate()
        shaker.stop()

    }

}

extension InterfaceController: WatchShakerDelegate
{
    func watchShaker(_ watchShaker: WatchShaker, didShakeWith sensibility: ShakeSensibility) {
        print("I'm shook! ⌚️⌚️⌚️")
    }

    func watchShaker(_ watchShaker: WatchShaker, didFailWith error: Error) {
        print(error.localizedDescription)
    }
}

Optional Directions

If you are interested, you can get the direction of the shake in the didShakeWith method.

func watchShaker(_ watchShaker: WatchShaker, didShakeWith sensibility: ShakeSensibility, 
                     direction: ShakeDirection) {
    print("I'm shook! ⌚️⌚️⌚️ \(direction)")
}

ShakeDirection is a simple enum that gives you up, down, left, or right directions. The image below shows how each direction is determined.

This gentleman below, for example, is clearly doing a shake with ShakeDirection.shakeDirectionRight 😂
