Lateral Raises AI Feature

Lift weights in both hands out to the sides of your body.

Lateral Raises

Feature

feature = .fitness(.lateralRaises)
feature = .fitness(.lateralRaises, style: customOrConditionalStyle)

Basic Implementation

To show results you'll need to modify your view ZStack, which is we assume is setup as described in the Getting Started Guide:

ZStack(alignment: .top) {
QuickPoseCameraView(useFrontCamera: true, delegate: quickPose)
QuickPoseOverlayView(overlayImage: $overlayImage)
}

The basic implementation will require displaying some text to the screen, start with declaring this value in your swiftui view.

@State private var feedbackText: String? = nil

And show this feedback text as an overlay to the view in your branding.

ZStack(alignment: .top) {
QuickPoseCameraView(useFrontCamera: true, delegate: quickPose)
QuickPoseOverlayView(overlayImage: $overlayImage)
}
.overlay(alignment: .center) {
if let feedbackText = feedbackText {
Text(feedbackText)
.font(.system(size: 26, weight: .semibold)).foregroundColor(.white).multilineTextAlignment(.center)
.padding(16)
.background(RoundedRectangle(cornerRadius: 8).foregroundColor(Color("AccentColor").opacity(0.8)))
.padding(.bottom, 40)
}
}

Note the above use of alignment in .overlay(alignment: .center), you can modify this to move the overlay around easily to say the bottom: .overlay(alignment: .bottom).

For this basic version it fills the feedback text with the Lateral Raise result as a percentage, and hides the text when the feature result is not available.

quickPose.start(features: [.fitness(.lateralRaises)], onFrame: { status, image, features, feedback, landmarks in
switch status {
case .success:
overlayImage = image
if let result = features.values.first {
feedbackText = "Lateral Raises: \(Int(result.value * 100))%"
} else {
feedbackText = nil
}
case .noPersonFound:
feedbackText = "Stand in view";
case .sdkValidationError:
feedbackText = "Be back soon";
}
})

Form Feedback

We recommend using the feature feedback to guide the user if an error occurs

quickPose.start(features: [.fitness(.lateralRaises)], onFrame: { status, image, features, feedback, landmarks in
switch status {
case .success:
overlayImage = image
if let result = features.values.first {
feedbackText = "Lateral Raises: \(Int(result.value * 100))%"
} else if let feedback = feedback.values.first, feedback.isRequired {
feedbackText = feedback.displayString
} else {
feedbackText = nil
}
case .noPersonFound:
feedbackText = "Stand in view";
case .sdkValidationError:
feedbackText = "Be back soon";
}
})

Body position: "Stand facing camera"

.body(feedback: standFacing, isRequired: true) 

Joint Visibility: "Move left arm into view" "Move right arm into view" "Move upper body into view"

.group(action: .move, group:.arm(side: .left), direction:.intoView, isRequired: true) 
.group(action: .move, group:.arm(side: .right), direction:.intoView, isRequired: true)
.group(action: .move, group:.upperBody, direction:.intoView, isRequired: true)

Exercise Specific: "Move arms apart"

.group(action: .move, group: .arms, direction: .apart, isRequired: true)

Conditional Styling

To give user feedback consider using conditional styling so that when the user's measurement goes above a threshold, here 0.8, a green highlight is shown.

let greenHighlightStyle = QuickPose.Style(conditionalColors: [QuickPose.Style.ConditionalColor(min: 0.8, max: nil, color: UIColor.green)])
quickPose.start(features: [.fitness(.lateralRaises, style: customOrConditionalStyle)],
onFrame: { status, image, features, feedback, landmarks in ...
})

Lateral Raise Counting

To count the Lateral Raises declare a configurable threshold counter, which can be used to turn lots of our features into counts.

@State private var counter = QuickPoseThresholdCounter()

Then pass QuickPose's Lateral Raise result to the counter, and display in the feedback text declared above.

quickPose.start(features: [.fitness(.lateralRaises)], onFrame: { status, image, features, feedback, landmarks in
switch status {
case .success:
overlayImage = image
if let result = features.values.first {
let counterState = counter.count(result.value)
feedbackText = "\(counterState.count) Lateral Raises"
} else {
feedbackText = nil
}

case .noPersonFound:
feedbackText = "Stand in view";
case .sdkValidationError:
feedbackText = "Be back soon";
}
})

Lateral Raise Timing

To time the Lateral Raises declare a configurable threshold timer, which can be used to turn lots of our features into timers. For Lateral Raises, we suggest modifying the default threshold, taking account of expected camera positioning and tilt.

@State private var timer = QuickPoseThresholdTimer(threshold: 0.2)

Then pass the result's raw value to the timer, and display in the feedback text declared above.

quickPose.start(features: [.fitness(.lateralRaises)], onFrame: { status, image, features, feedback, landmarks in
switch status {
case .success:
overlayImage = image
if let result = features.values.first {
let timerState = timer.time(result.value)
feedbackText = String(format: "%.1f", timerState.time) + "secs"
} else {
feedbackText = nil
}

case .noPersonFound:
feedbackText = "Stand in view";
case .sdkValidationError:
feedbackText = "Be back soon";
}
})
