• Occlusion Handling: Robust against partial visibility

Form Analysis Metrics 📐

struct BasketballPose {
    let shoulderAngle: Double    // Ideal: 90° ± 10°
    let elbowAngle: Double       // Ideal: 90° ± 10°
    let wristAngle: Double       // Ideal: 45° ± 15°
    let kneeAngle: Double        // Ideal: 120° ± 20°
    let bodyAlignment: Double    // Ideal: 0° ± 15°
    let followThrough: Double    // Ideal: 80%+ extension
}

Scoring Algorithm 🏆

var overallScore: Double {
    let shoulderScore = max(0, 100 - abs(shoulderAngle - 90) * 2)
    let elbowScore = max(0, 100 - abs(elbowAngle - 90) * 2)
    let wristScore = max(0, 100 - abs(wristAngle - 45) * 3)
    let kneeScore = max(0, 100 - abs(kneeAngle - 120) * 1.5)
    let alignmentScore = max(0, 100 - bodyAlignment * 2)
    let followThroughScore = max(0, followThrough * 100)
    
    return (shoulderScore + elbowScore + wristScore + 
            kneeScore + alignmentScore + followThroughScore) / 6.0
}
