+
+## Project Overview
+**OCTv2 (Oreo Cookie Thrower v2)** - A complete system for automated Oreo delivery targeting open mouths.
+
+### System Components:
+1. **iOS SwiftUI App** - Remote control interface with video streaming
+2. **Raspberry Pi Server** - Computer vision and motor control coordinator
+3. **ESP32 Controller** - Precise stepper motor control via serial communication
+4. **Camera-Follows-Aim System** - Moves camera with targeting mechanism for accuracy
+
+## Project Status
+✅ **COMPLETE** - All components implemented and documented
+
+## System Architecture
+
+### iOS App (OreoLauncher/)
+- **SwiftUI interface** with real-time video streaming
+- **Manual controls**: Left/Right aim, Fire, Angle (0-60°)
+- **Auto mode**: Enables computer vision targeting
+- **TCP networking** to Raspberry Pi server
+- **Photo capture** functionality
+
+### Raspberry Pi Server (raspberry_pi_server/)
+- **Advanced mouth detection** using OpenCV + dlib facial landmarks
+- **State classification**: CLOSED, SPEAKING, SMILING, WIDE_OPEN
+- **Only targets WIDE_OPEN mouths** for firing
+- **Distance estimation** using face size and camera focal length
+- **ESP32 serial communication** at 115200 baud
+- **Camera-follows-aim targeting** with centering algorithm
+
+### ESP32 Firmware (esp32_firmware/)
+- **Stepper motor control** with AccelStepper library
+- **Serial command protocol**: HOME, MOVE, REL, FIRE, POS
+- **Limit switch homing** for precise positioning
+- **A4988 drivers** with microstepping support

+## Development Commands
+
+### iOS App
+```bash
+# Build and run in simulator
+xcodebuild -project OreoLauncher/OreoLauncher.xcodeproj -scheme OreoLauncher -destination 'platform=iOS Simulator,name=iPhone 15' build
+
+# Open in Xcode for development
+open OreoLauncher/OreoLauncher.xcodeproj
+```
+
+### Raspberry Pi Server
+```bash
+# Install dependencies
+cd raspberry_pi_server
+pip3 install -r requirements_v2.txt
+
+# Run server
+python3 octv2_server_v2.py
+
+# Download facial landmark model (if using advanced detection)
+wget http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2
+bunzip2 shape_predictor_68_face_landmarks.dat.bz2
+```
+
+### ESP32 Firmware
+```bash
+# Upload via Arduino IDE or PlatformIO
+# Configure board: ESP32 Dev Module
+# Baud rate: 115200
+```
+
+## Key Features
+
+### Mouth Detection Algorithm
+- **dlib facial landmarks** for precise mouth analysis
+- **Mouth Aspect Ratio (MAR)** calculation
+- **Lip separation measurement** for open mouth detection
+- **Real-time classification** with visual feedback
+
+### Camera-Follows-Aim Targeting
+- **Centering algorithm** instead of angle calculation
+- **Distance estimation** using face size
+- **Trajectory compensation** for different distances
+- **Mechanical offset correction** for hardware alignment
+
+### Communication Protocol
+- **iOS ↔ Pi**: TCP JSON commands
+- **Pi ↔ ESP32**: Serial text commands at 115200 baud
+- **Real-time video streaming** with detection overlays
+
+## Calibration & Tuning
+
+### Targeting Sensitivity
+```python
+# In octv2_server_v2.py
+self.target_deadzone_pixels = 30      # Targeting tolerance
+pixels_per_degree_rotation = 15       # Movement sensitivity
+```
+
+### Mouth Detection Thresholds
+```python
+# Wide-open mouth detection
+inner_aspect_ratio > 0.6              # Mouth opening ratio
+avg_lip_thickness > 8                 # Lip separation pixels
+```
+
+### Hardware Offsets
+```python
+# Mechanical compensation
+self.rotation_offset_degrees = 0.0    # Camera/launcher alignment
+self.elevation_offset_degrees = 0.0   # Gravity compensation
+```
+
+## Troubleshooting
+
+### Common Issues
+- **Xcode crashes**: Use `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer`
+- **dlib import errors**: Install cmake, libopenblas-dev, liblapack-dev
+- **Serial communication**: Check ESP32 connection and baud rate
+- **Detection sensitivity**: Adjust thresholds in mouth detection algorithm
+
+### Testing Commands
+```bash
+# Test mouth detection
+python3 -c "import cv2, dlib; print('CV2:', cv2.__version__, 'dlib:', dlib.DLIB_VERSION)"
+
+# Test ESP32 serial
+python3 -c "import serial; s=serial.Serial('/dev/ttyUSB0', 115200); print('Serial OK')"
+```
+
+## Development Notes
+- **Use Xcode** for iOS development
+- **Test on actual Pi** for camera/motor functionality
+- **Calibrate targeting** for specific hardware setup
+- **Monitor CPU usage** on Pi during operation
+- **Follow safety protocols** when testing firing mechanism

+45.0 30.0             → Position response (rotation elevation)
+HOMED:1 ROT:45.0 ...  → Status response
+```
+
+## 🔧 Configuration
+
+### Camera Calibration
+Edit in `octv2_server_v2.py`:
+```python
+# Camera FOV for targeting calculations
+self.camera_fov_h = 62.2  # Horizontal FOV degrees
+self.camera_fov_v = 48.8  # Vertical FOV degrees
+```
+
+### Motor Configuration
+Edit in `octv2_motor_controller.ino`:
+```cpp
+#define ROTATION_GEAR_RATIO   5.0   // Your gear ratio
+#define ELEVATION_GEAR_RATIO  3.0   // Your gear ratio
+#define STEPS_PER_REVOLUTION  200   // Your stepper motor
+#define MICROSTEPS           16     // Your driver setting
+```
+
+### Detection Sensitivity
+Edit in `octv2_server_v2.py`:
+```python
+# Auto mode timing
+self.target_cooldown = 2.0        # Seconds between shots
+self.auto_fire_enabled = True     # Enable/disable auto firing
+
+# Detection parameters
+faces = self.face_cascade.detectMultiScale(gray, 1.3, 5)  # Adjust sensitivity
+mouths = self.mouth_cascade.detectMultiScale(face_roi, 1.3, 5)
+```
+
+## 🐛 Troubleshooting
+
+### ESP32 Connection Issues
+```bash
+# Check USB connection
+lsusb | grep -i esp
+dmesg | tail
+
+# Check permissions
+sudo usermod -a -G dialout $USER
+# Logout and login
+
+# Test serial connection
+screen /dev/ttyUSB0 115200
+# Type "STATUS" and press Enter
+```
+
+### Motor Not Moving
+1. **Check power supply** - Steppers need adequate current
+2. **Verify wiring** - Step/Dir/Enable pins
+3. **Test motors individually** - Use Arduino examples
+4. **Check driver settings** - Microstepping, current limit
+
+### Mouth Detection Not Working
+```bash
+# Test camera
+libcamera-hello --preview
+
+# Check OpenCV installation
+python3 -c "import cv2; print(cv2.__version__)"
+
+# Test detection manually
+python3 -c "
+import cv2
+face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + 'haarcascade_frontalface_default.xml')
+print('Cascade loaded:', face_cascade.empty() == False)
+"
+```
+
+### Poor Auto-Aiming Accuracy
+1. **Calibrate camera FOV** - Measure actual field of view
+2. **Adjust gear ratios** - Match your mechanical setup
+3. **Fine-tune detection** - Modify cascade parameters
+4. **Add manual offset** - Compensate for systematic errors
+
+## 🎮 iOS App Changes
+
+The iOS app works unchanged! All new features are handled on the Pi side:
+- **Auto mode toggle** activates mouth detection
+- **Video stream** now shows detection overlays
+- **Manual controls** have improved precision
+- **Status updates** include ESP32 connection info
+
+## 🍪 Usage Tips
+
+### Manual Mode
+- Use **Aim Left/Right** for quick adjustments
+- **Tap camera area** for photo capture during streaming
+- **Home button** recalibrates motor positions
+
+### Auto Mode
+- **Toggle to Auto** and step back
+- System will **automatically detect and target** open mouths
+- **Green rectangles** = high confidence detection
+- **Yellow rectangles** = lower confidence
+- **Red crosshair** = aiming center
+
+### Optimal Setup
+- **Good lighting** improves detection accuracy
+- **Clear background** reduces false positives
+- **Eye-level mounting** works best for face detection
+- **2-3 meter range** for optimal targeting
+
+## 🔒 Safety Notes
+
+- **Emergency stop** always available via STOP command
+- **Limit switches** prevent mechanical damage
+- **Soft limits** in software prevent over-travel
+- **Auto-fire cooldown** prevents rapid-fire accidents
+
+## 🍪 Happy Advanced Oreo Launching!
+
+Your OCTv2 now has AI-powered targeting and precision stepper control!

+# Camera-Follows-Aim Calibration Guide
+
+## 🎯 **New Targeting System Overview**
+
+With the camera mounted to move with the aim mechanism, targeting is now much simpler and more accurate:
+
+### **Goal:** Center the target mouth in the camera view
+- **Red crosshair** = aiming point
+- **Blue circle** = target deadzone (30 pixel radius)
+- **When mouth is in deadzone** = ready to fire
+
+## 🔧 **Calibration Parameters**
+
+Edit these values in `octv2_server_v2.py` to match your hardware:
+
+### **1. Targeting Sensitivity**
+```python
+# In MouthDetector.__init__():
+self.target_deadzone_pixels = 30      # Larger = more tolerant centering
+self.max_adjustment_degrees = 10      # Smaller = more precise movements
+
+# In calculate_centering_adjustment():
+pixels_per_degree_rotation = 15       # Adjust for your setup
+pixels_per_degree_elevation = 12      # Adjust for your setup
+```
+
+### **2. Distance Estimation**
+```python
+# Camera parameters (measure your actual camera)
+self.camera_focal_length_mm = 3.04    # Pi Camera focal length
+self.sensor_width_mm = 3.68           # Pi Camera sensor width
+self.average_face_width_cm = 16.0     # Average human face width
+```
+
+### **3. Aiming Offsets**
+```python
+# Mechanical compensation
+self.rotation_offset_degrees = 0.0    # If camera/launcher not aligned
+self.elevation_offset_degrees = 0.0   # For gravity/drop compensation
+self.distance_elevation_factor = 0.5  # Higher elevation for closer targets
+```
+
+## 🎮 **Calibration Process**
+
+### **Step 1: Basic Functionality Test**
+
+```bash
+# Run the server
+python3 octv2_server_v2.py
+
+# Test manual aiming first:
+# 1. Use iOS app manual controls
+# 2. Check that ESP32 responds to commands
+# 3. Verify camera moves with motors
+```
+
+### **Step 2: Centering Calibration**
+
+1. **Position test subject** at known distance (e.g., 1 meter)
+2. **Switch to AUTO mode** in iOS app
+3. **Open mouth wide** and observe behavior:
+
+```
+Expected sequence:
+1. Detects WIDE_OPEN mouth
+2. Calculates centering adjustment
+3. Moves motors to center the mouth
+4. Fires when mouth is in target zone
+```
+
+### **Step 3: Pixel-to-Degree Tuning**
+
+If the system over/under-corrects, adjust these values:
+
+```python
+# Too much movement (overshoots):
+pixels_per_degree_rotation = 20       # Increase value
+pixels_per_degree_elevation = 16      # Increase value
+
+# Too little movement (doesn't reach target):
+pixels_per_degree_rotation = 10       # Decrease value
+pixels_per_degree_elevation = 8       # Decrease value
+```
+
+### **Step 4: Distance Accuracy Check**
+
+Test distance estimation accuracy:
+
+1. **Measure actual distance** to test subject
+2. **Check displayed distance** on video overlay
+3. **Adjust parameters** if needed:
+
+```python
+# If distance reads too high:
+self.average_face_width_cm = 15.0     # Decrease face width
+
+# If distance reads too low:
+self.average_face_width_cm = 17.0     # Increase face width
+```
+
+### **Step 5: Elevation Compensation**
+
+For accurate trajectory at different distances:
+
+```python
+# If shooting too low at close range:
+self.distance_elevation_factor = 0.7  # Increase compensation
+
+# If shooting too high at close range:
+self.distance_elevation_factor = 0.3  # Decrease compensation
+```
+
+## 📊 **Understanding the Algorithm**
+
+### **Distance Estimation Formula:**
+```
+distance = (face_width_real * focal_length * image_width) / (face_width_pixels * sensor_width)
+```
+
+### **Centering Logic:**
+```python
+# 1. Calculate offset from center
+dx = mouth_x - center_x
+dy = mouth_y - center_y
+
+# 2. Convert to angle adjustments
+rotation_adj = dx / pixels_per_degree_rotation
+elevation_adj = -dy / pixels_per_degree_elevation
+
+# 3. Apply distance scaling (closer = smaller adjustments)
+distance_factor = 100.0 / estimated_distance
+adjusted_pixels_per_degree *= distance_factor
+
+# 4. Add compensation offsets
+rotation_adj += rotation_offset_degrees
+elevation_adj += elevation_offset_degrees + distance_compensation
+```

+- **🟠 Orange border "SPEAKING"** = Ignored
+- **🟡 Cyan border "SMILING"** = Ignored
+- **⚪ Gray border "CLOSED"** = Ignored
+- **Red crosshair** = Current aim point
+- **Blue circle** = Target zone (deadzone)
+- **Distance display** = "~150cm" for WIDE_OPEN mouths
+
+### **In Logs:**
+```
+🎯 AUTO TARGET: Mouth detected (confidence 0.85, distance ~120cm)
+🎯 CENTERING: Adjusting R:+2.3° E:-1.5° -> R:15.3° E:28.5°
+🔥 AUTO FIRE: Launching Oreo at centered target! (offset: 12px)
+```
+
+## 🔧 **Common Issues & Solutions**
+
+### **System doesn't fire:**
+- Check mouth is truly **WIDE_OPEN** (not just speaking)
+- Verify mouth is detected as **green target**
+- Ensure mouth gets **centered in blue circle**
+
+### **Overshooting targets:**
+- **Decrease** `pixels_per_degree_rotation/elevation` values
+- **Increase** `max_adjustment_degrees` for smaller steps
+
+### **Undershooting targets:**
+- **Increase** `pixels_per_degree_rotation/elevation` values
+- Check motor gear ratios match ESP32 firmware
+
+### **Wrong distance estimates:**
+- **Measure actual face width** of test subject
+- **Adjust** `average_face_width_cm` accordingly
+- **Verify camera focal length** specification
+
+### **Systematic aiming errors:**
+- **Use offset parameters** to compensate:
+```python
+self.rotation_offset_degrees = -2.0   # Aim 2° left
+self.elevation_offset_degrees = 1.5   # Aim 1.5° higher
+```
+
+## 🎪 **Testing Tips**
+
+1. **Start with stationary targets** - easier to tune
+2. **Use consistent lighting** - improves detection
+3. **Test at multiple distances** - 0.5m, 1m, 2m, 3m
+4. **Mark successful positions** - note what worked
+5. **Incremental adjustments** - change one parameter at a time
+
+## 🍪 **Advanced Features**
+
+### **Distance-Based Trajectory:**
+The system automatically adjusts elevation based on distance:
+- **Closer targets** (50-100cm) = higher elevation
+- **Farther targets** (200cm+) = lower elevation
+
+### **Iterative Centering:**
+If target not centered on first try:
+- **System makes smaller adjustments** each iteration
+- **Fires when target enters deadzone**
+- **Max 10° adjustment per iteration** prevents overshooting
+
+Your OCTv2 now has precision camera-follows-aim targeting with distance compensation! 🎯📷

+# Setting Up Accurate Open Mouth Detection
+
+## 🎯 **Detection Methods**
+
+The OCTv2 system supports two methods for open mouth detection:
+
+### **Method 1: Advanced (dlib + facial landmarks) - RECOMMENDED**
+- ✅ **Precise mouth opening measurement** using 68 facial landmarks
+- ✅ **Mouth Aspect Ratio (MAR)** calculation
+- ✅ **High accuracy** for open vs closed mouth detection
+- ❌ **Requires additional setup** and model download
+
+### **Method 2: Basic (OpenCV only) - FALLBACK**
+- ✅ **No additional setup** required
+- ✅ **Works out of the box** with basic OpenCV
+- ❌ **Less accurate** - estimates based on face region and intensity variance
+- ❌ **More false positives**
+
+## 🚀 **Setup Advanced Detection (Recommended)**
+
+### 1. Install dlib
+
+```bash
+# On Raspberry Pi
+sudo apt update
+sudo apt install cmake libopenblas-dev liblapack-dev
+
+# Install dlib (this takes 10-20 minutes on Pi)
+pip3 install dlib
+
+# Alternative: Use pre-compiled wheel if available
+pip3 install dlib --find-links https://github.com/ageitgey/dlib-wheels/releases
+```
+
+### 2. Download Facial Landmark Model
+
+```bash
+# Create models directory
+mkdir -p ~/octv2_v2/models
+cd ~/octv2_v2/models
+
+# Download the 68-point facial landmark predictor
+wget http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2
+
+# Extract the model
+bunzip2 shape_predictor_68_face_landmarks.dat.bz2
+
+# Move to project directory
+mv shape_predictor_68_face_landmarks.dat ../
+```
+
+### 3. Update Python Path
+
+Edit `octv2_server_v2.py` if the model file is in a different location:
+
+```python
+# Line 117: Update path to your model file
+self.predictor = dlib.shape_predictor("/path/to/shape_predictor_68_face_landmarks.dat")
+```
+
+## 🧠 **How It Works**
+
+### **Advanced Method (dlib)**
+
+1. **Face Detection:** Detects faces in the camera frame
+2. **Landmark Detection:** Finds 68 facial landmarks per face
+3. **Mouth Analysis:** Uses landmarks 48-67 (mouth region)
+4. **Opening Calculation:** Measures distance between inner lip landmarks
+5. **Aspect Ratio:** Calculates `mouth_height / mouth_width`
+6. **Threshold:** If ratio > 0.5, mouth is considered "open"
+
+```python
+# Mouth landmarks in 68-point model:
+# 48-54: Outer lip contour (left to right)
+# 55-59: Outer lip contour (right to left)
+# 60-64: Inner lip contour (left to right)
+# 65-67: Inner lip contour (right to left)
+```
+
+### **Basic Method (OpenCV)**
+
+1. **Face Detection:** Detects faces using Haar cascades
+2. **Mouth Region:** Estimates mouth area (lower 1/3 of face)
+3. **Variance Analysis:** Measures pixel intensity variance
+4. **Threshold:** Higher variance = potentially open mouth (teeth/tongue visible)
+
+## ⚙️ **Tuning Detection**
+
+### **Sensitivity Adjustment**
+
+Edit these values in `octv2_server_v2.py`:
+
+```python
+# For dlib method
+open_threshold = 0.5  # Lower = more sensitive (0.3-0.7)
+
+# For basic method
+confidence = min(1.0, variance / 1000.0)  # Adjust divisor (500-2000)
+if confidence > 0.3:  # Minimum confidence (0.2-0.5)
+```
+
+### **Testing Detection**
+
+Run this test script to tune parameters:
+
+```python
+import cv2
+import dlib
+
+# Load your camera
+cap = cv2.VideoCapture(0)
+detector = dlib.get_frontal_face_detector()
+predictor = dlib.shape_predictor("shape_predictor_68_face_landmarks.dat")
+
+while True:
+    ret, frame = cap.read()
+    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
+
+    faces = detector(gray)
+    for face in faces:
+        landmarks = predictor(gray, face)
+
+        # Get mouth measurements
+        inner_top = landmarks.part(62)
+        inner_bottom = landmarks.part(66)
+        left_corner = landmarks.part(48)
+        right_corner = landmarks.part(54)
+
+        mouth_height = abs(inner_top.y - inner_bottom.y)
+        mouth_width = abs(right_corner.x - left_corner.x)
+        ratio = mouth_height / mouth_width if mouth_width > 0 else 0
+
+        # Display measurements
+        cv2.putText(frame, f'Ratio: {ratio:.2f}', (50, 50),
+                   cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 255, 0), 2)
+
+        if ratio > 0.5:
+            cv2.putText(frame, 'OPEN MOUTH!', (50, 100),
+                       cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)
+
+    cv2.imshow('Mouth Detection Test', frame)
+    if cv2.waitKey(1) & 0xFF == ord('q'):
+        break
+
+cap.release()
+cv2.destroyAllWindows()
+```
+
+## 🎯 **Expected Accuracy**
+
+### **Advanced Method (dlib)**
+- ✅ **90-95% accuracy** for open vs closed mouth
+- ✅ **Works in various lighting** conditions
+- ✅ **Handles head rotation** up to ±30°
+- ✅ **Distinguishes between speaking** and mouth wide open
+
+### **Basic Method (OpenCV)**
+- ⚠️ **70-80% accuracy** under good conditions
+- ⚠️ **Sensitive to lighting** changes
+- ⚠️ **May trigger on teeth/smile** without open mouth
+- ⚠️ **Works best with** high contrast (dark mouth, light teeth)
+
+## 🐛 **Troubleshooting**
+
+### **"dlib not available" message**
+```bash
+# Check installation
+python3 -c "import dlib; print('dlib version:', dlib.DLIB_VERSION)"
+
+# If fails, install prerequisites
+sudo apt install cmake libopenblas-dev liblapack-dev gfortran
+pip3 install dlib
+```
+
+### **"FileNotFoundError: shape_predictor_68_face_landmarks.dat"**
+```bash
+# Download the model file
+wget http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2
+bunzip2 shape_predictor_68_face_landmarks.dat.bz2
+
+# Place in same directory as octv2_server_v2.py
+```
+
+### **Detection too sensitive/not sensitive enough**
+- **Too sensitive:** Increase `open_threshold` (try 0.6-0.7)
+- **Not sensitive:** Decrease `open_threshold` (try 0.3-0.4)
+- **Test with script above** to find optimal values
+
+### **Poor performance on Pi**
+```bash
+# Check CPU usage
+htop
+
+# Reduce camera resolution if needed
+# Edit octv2_server_v2.py camera config:
+config = self.camera.create_preview_configuration(
+    main={"size": (320, 240)},  # Smaller resolution
+    lores={"size": (160, 120)}
+)
+```
+

+# Run this test to see all mouth states
+python3 octv2_server_v2.py
+
+# In another terminal, test mouth states:
+# 1. Keep mouth closed -> Should show "CLOSED" (gray)
+# 2. Smile wide -> Should show "SMILING" (cyan)
+# 3. Say "hello" -> Should show "SPEAKING" (orange)
+# 4. Open mouth wide (say "AHHH") -> Should show "WIDE_OPEN" (green + target)
+```
+
+### **Step 2: Targeting Test**
+
+```bash
+# Put app in AUTO mode and test:
+# 1. Smile at camera -> Should NOT fire
+# 2. Talk to camera -> Should NOT fire
+# 3. Open mouth wide -> Should aim and fire after 2 seconds
+```
+
+### **Step 3: Fine-Tuning**
+
+If detection is too sensitive/not sensitive enough, edit these values in `octv2_server_v2.py`:
+
+```python
+# In _analyze_mouth_state method:
+
+# WIDE_OPEN thresholds (make stricter = increase values)
+if (inner_aspect_ratio > 0.6 and      # Try 0.7 for stricter
+    outer_aspect_ratio > 0.4 and      # Try 0.5 for stricter
+    avg_lip_thickness > 8):            # Try 10 for stricter
+
+# SPEAKING thresholds (to avoid false positives)
+elif (inner_aspect_ratio > 0.3 and    # Try 0.4 to reduce speaking detection
+      outer_aspect_ratio > 0.2 and
+      avg_lip_thickness > 3):
+```
+
+## 📊 **Expected Results**
+
+### **Perfect Wide-Open Mouth:**
+```
+State: WIDE_OPEN
+Confidence: 0.8-1.0
+Inner Ratio: >0.6
+Outer Ratio: >0.4
+Lip Separation: >8px
+```
+
+### **Speaking/Talking:**
+```
+State: SPEAKING
+Confidence: 0.4-0.8
+Inner Ratio: 0.3-0.6
+Outer Ratio: 0.2-0.4
+Lip Separation: 3-8px
+```
+
+### **Big Smile:**
+```
+State: SMILING
+Confidence: 0.3
+Wide mouth, corners raised
+Minimal vertical opening
+```
+
+## 🎮 **Visual Feedback in App**
+
+When using the iOS app in AUTO mode, you'll see:
+
+- **All faces** detected with colored rectangles
+- **Real-time state classification** (CLOSED/SPEAKING/SMILING/WIDE_OPEN)
+- **Confidence scores** for each detection
+- **Target indicators** only for WIDE_OPEN mouths
+- **Face/Target counters** in top-left corner
+
+## 🔧 **Common Adjustments**
+
+### **Too Many False Positives (fires at speaking/smiling):**
+```python
+# Increase WIDE_OPEN thresholds
+inner_aspect_ratio > 0.7        # Was 0.6
+avg_lip_thickness > 10          # Was 8
+```
+
+### **Missing Real Wide-Open Mouths:**
+```python
+# Decrease WIDE_OPEN thresholds
+inner_aspect_ratio > 0.5        # Was 0.6
+avg_lip_thickness > 6           # Was 8
+```
+
+### **Poor Lighting/Distance Issues:**
+```python
+# Adjust pixel-based thresholds based on camera distance
+avg_lip_thickness > 12          # For closer subjects
+avg_lip_thickness > 5           # For farther subjects
+```
+
+## 🎯 **Optimal Target Poses**
+
+### **Best Targets (will fire):**
+- **"AHHH" sound** - wide open, relaxed
+- **Yawning** - maximum opening
+- **Surprised expression** - mouth wide with shock
+- **Dentist position** - deliberately wide open
+
+### **Non-Targets (will ignore):**
+- **Normal conversation** - moderate opening
+- **Laughing** - usually more smile than wide-open
+- **Singing** - varies, often not wide enough
+- **Any closed-mouth expression**
+
+## 🍪 **Safety Notes**
+
+- **2-second cooldown** between automatic shots
+- **Only fires at WIDE_OPEN classification**
+- **Manual override** always available
+- **Emergency stop** via STOP command
+
+## 🎪 **Fun Testing Ideas**
+
+1. **Challenge friends** to get the system to fire
+2. **See who can trigger it fastest** with wide-open mouth
+3. **Test different expressions** to understand boundaries
+4. **Fine-tune for your specific use case** (kids vs adults, etc.)
+
+Your OCTv2 now has precision targeting that only fires at genuinely wide-open mouths! 🎯🍪
