TherapyLens 🧠

Tagline: "Empowering therapists with real-time behavioral insights through ethical AI"

Overview

TherapyLens is an AI-powered assistant that helps therapists detect non-verbal cues during therapy sessions by analyzing eye movement patterns and breathing through a webcam. It provides real-time behavioral insights and post-session summaries while maintaining strict privacy and ethical standards.

Usage Guide

Starting a Session

1. Patient Consent

   • Click "Start Session" button
   • Webcam activates with visual indicator
   • Real-time metrics begin displaying

3. During Session

   • Monitor behavioral metrics in real-time
   • Review AI insights in the "AI Insights" tab
   • Pause tracking during sensitive moments
   • System generates alerts for significant changes

4. End Session

   • Click "End Session" button
   • Comprehensive report is automatically generated
   • Export report as JSON if needed
   • Delete all data when finished

Understanding Metrics

Eye Contact (%)

• Percentage of time patient maintains eye contact
• Green: 40%+ (typical)
• Yellow: 20-40% (may indicate discomfort)
• Red: <20% (prolonged avoidance)
• Note: Baselines vary for neurodivergent individuals

Breathing Rate (bpm)

• Breaths per minute
• Green: 10-18 bpm (normal)
• Yellow: 19-24 bpm (elevated, possible stress)
• Red: 25+ bpm (hyperventilation)

Gaze Stability (%)

• Measures fixation vs. rapid eye movement
• Green: 60-90% (balanced)
• Yellow: <30% (rapid movement, anxiety) or >95% (fixed stare, dissociation)

Interpreting Alerts

🟡 Warning Alerts

• Breathing rate increased 50%
• No eye contact for extended period
• Rapid eye movement suggesting anxiety
• Gaze patterns suggest dissociation

🔴 Critical Alerts

• Hyperventilation detected (25+ breaths/min)
• Prolonged fixed gaze (possible dissociation)
• Extreme breathing changes

AI Insights

Claude analyzes patterns and provides:

• Contextual behavioral observations
• Gentle therapeutic suggestions
• Pattern recognition across session
• Non-diagnostic, professional guidance

Example insight:

"Patient's breathing became shallow when discussing work stress. Consider exploring this topic further. The physiological response suggests this may be a significant stressor worth examining."

Privacy & Security

What is NOT Stored

• ❌ Video recordings
• ❌ Audio recordings
• ❌ Facial images
• ❌ Identifying information
• ❌ Session content or dialogue

What IS Stored (Temporarily)

• ✅ Anonymized behavioral metrics
• ✅ Timestamps and durations
• ✅ Alert notifications
• ✅ AI-generated insights

Data Lifecycle

1. During Session: Metrics stored in browser memory only
2. After Session: Report can be exported as anonymized JSON
3. Deletion: All data can be permanently deleted with one click
4. Default: No automatic cloud upload or long-term storage

HIPAA Compliance

• All processing happens locally in the browser
• No data transmission except to Claude API (for insights only)
• Claude API calls do not include identifying patient information
• Therapist maintains full control over data retention
• Export functionality allows manual backup to encrypted storage

Neurodiversity Considerations

Autism Spectrum

• Lower baseline eye contact is normal, not anxiety
• System learns individual patterns
• Alerts calibrated to personal baseline
• Cultural eye contact variations respected

ADHD

• More gaze movement during concentration is expected
• Fidgeting patterns tracked separately
• Difficulty with transitions noted in reports

Trauma Survivors

• Freeze responses (fixed gaze, shallow breathing) identified
• Dissociation patterns flagged
• Grounding exercise effectiveness tracked

API Integration

Claude API Setup

The application uses the Anthropic Messages API for behavioral analysis:

const response = await fetch('https://api.anthropic.com/v1/messages', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'claude-sonnet-4-20250514',
    max_tokens: 1000,
    messages: [{ role: 'user', content: prompt }]
  })
});

Note: In the current implementation, API authentication is handled through the Claude.ai artifact environment. For production deployment, you'll need to add proper API key management.

Adding API Key for Production

// Add to fetch headers:
headers: {
  'Content-Type': 'application/json',
  'x-api-key': 'your-anthropic-api-key',
  'anthropic-version': '2023-06-01'
}

Customization

Adjusting Alert Thresholds

Edit the checkForAlerts function:

// Hyperventilation threshold
if (br > 25) {  // Change 25 to desired threshold
  addAlert('critical', `Hyperventilation detected`);
}

// Eye contact threshold
if (ec < 20) {  // Change 20 to desired threshold
  addAlert('warning', `Minimal eye contact`);
}

Changing Insight Frequency

Edit the useEffect for Claude insights:

// Current: every 120 seconds (2 minutes)
if (sessionDuration > 0 && sessionDuration % 120 === 0) {
  generateClaudeInsight();
}

// Change to every 3 minutes:
if (sessionDuration > 0 && sessionDuration % 180 === 0) {
  generateClaudeInsight();
}

Customizing Patient Baselines

Default values in TherapyLens.jsx:

const [baselineBreathing, setBaselineBreathing] = useState(14);
const [baselineEyeContact, setBaselineEyeContact] = useState(45);

These can be adjusted per-patient in the "Patient Baseline" tab.

Ethical Considerations

Therapist Guidelines

• Always obtain informed consent
• Use as supplementary tool, not replacement for clinical judgment
• Respect patient autonomy (allow pause/stop)
• Delete data when no longer needed
• Never use for diagnosis without proper clinical training
• Be transparent about AI limitations

Patient Rights

• Right to decline tracking
• Right to pause at any time
• Right to view all collected data
• Right to request deletion
• Right to understand how AI works
• Right to questions and concerns

Limitations

• AI cannot diagnose mental health conditions
• Cultural and individual variations exist
• Not a replacement for therapist observation
• Requires clinical interpretation
• May not work equally for all populations
