Step-by-Step Instructions

1

Find Proper Lighting

Position yourself near a window for natural daylight, or use bright indoor lights. Avoid harsh shadows on your face.

💡 Why it matters: Good lighting is essential for accurate color analysis. Natural daylight provides the most true-to-life tongue color, which is critical for TCM diagnosis.
2

Extend Your Tongue Naturally

Open your mouth naturally and stick out your tongue straight ahead. Keep it relaxed - don't tense or force it.

💡 Why it matters: A relaxed tongue shows its true color and coating. Forcing or tensing your tongue can temporarily change its appearance and color, affecting diagnosis accuracy.
3

Position Camera Correctly

Hold your camera or phone 6-8 inches (15-20 cm) from your face at eye level. Frame the shot so your tongue fills most of the image.

💡 Why it matters: Proper distance and angle ensure the AI can see the entire tongue surface from tip to root. All regions are important for comprehensive TCM pattern analysis.
4

Ensure Sharp Focus

Tap on your tongue in the camera preview to ensure it's in focus. Your tongue should appear sharp and clear with visible details.

💡 Why it matters: Sharp focus allows the AI to detect subtle coating patterns, texture variations, and edge characteristics that are diagnostic indicators in TCM.
5

Capture and Review

Hold still and take 2-3 photos. Review them and select the clearest image with good lighting and proper focus.

💡 Why it matters: Taking multiple photos increases your chances of capturing the perfect shot. Even small movements can cause blur, so review carefully before submitting.

📋 Best Practices for Accurate Results

⏰ Best Time

Morning before eating or drinking

Take photos in the morning for most accurate results. Food, drinks, and brushing can temporarily affect tongue appearance.

🚫 What to Avoid

  • Sticking tongue out forcefully
  • Taking photos right after eating colored foods
  • Using flash directly on your tongue
  • Capturing from extreme angles

✅ Quality Checklist

  • Entire tongue visible (tip to root)
  • Natural color (no yellow/artificial lighting)
  • Sharp and in focus
  • No shadows obscuring the surface

🔄 When to Retake

  • Photo is blurry or out of focus
  • Lighting creates harsh shadows
  • Only part of tongue is visible
  • Colors look unnatural or distorted

❌ Common Mistakes to Avoid

Poor Lighting

Problem: Dim lighting or harsh artificial light distorts tongue color.

Solution: Use natural daylight from a window, or bright, evenly distributed indoor lights.

Camera Too Close or Far

Problem: Too close causes blur; too far makes details hard to see.

Solution: Maintain 6-8 inches (15-20 cm) distance for optimal framing and focus.

Tensed Tongue

Problem: Forcing tongue out changes its natural color and shape.

Solution: Relax and extend tongue naturally. Practice a few times before capturing.

Partial View

Problem: Only showing tongue tip misses important diagnostic areas.

Solution: Frame shot to show entire tongue from tip to root, including sides.
