What does it do?
5-second recording → Instant scoring: Recording a 5-second video with the camera displays a stress, anxiety, and tension index score from 0 to 100, along with a status label (normal/caution/concern) as an emoji.
Individual/group trends: Track trends over the past 1-4 weeks, and even monitor changes in group mood with a class-level "heatmap."
Notification & Linkage: If a continuous "concern" or higher level is detected, a silent notification is sent to the administrator.
→ Short interviews and consultations are connected.
How does it work? (Non-invasive/non-contact)
Video recording (5 seconds)
Facial expressions and micro-muscle movements (micro-expressions)
Signal matching: Ambient brightness/frame rate/face angle correction, noise removal
Explanatory output: Provides interpretation support phrases such as "Tension ↑, suspected signs of sleep deprivation (blinking ↑)"
Caution: This is an "emotional status screening," not a medical diagnosis.
This does not replace specific physical or mental health assessments.
Example of Results Screen
Immediate Results:
Stress 68 (Caution), Anxiety 52 (Caution), Tension 74 (Concern)
Trend: 1-month line chart, calendar emoji
Full Post-Incident Screening: Check all days of stressful events such as conflicts, exams, and competitions to assess the aftermath.
Counseling Linkage: Continuous "Concern" or higher → Individually notify the manager → Short interview → Communication with guardian if necessary.
Environmental Impact: Frontal face, 30–60cm distance, appropriate lighting (avoid backlighting or flickering lights). Masks/face coverings and strenuous movement may degrade image quality.
Individual Differences: Sleep, caffeine, and post-exercise conditions may affect the signal.
False Alarm Mitigation: Do not respond to single signals; cross-check with continuity/trends and manager observation.
Crisis Protocol: Prepare action guidelines for each level of concern in advance (interview template, manager guidance form).
Frequently Asked Questions (Brief)
Q. Does it "detect" behavior?
A. It doesn't directly identify the behavior. However, it provides early warning signals (e.g., persistent tension, heightened anxiety) that often accompany victimization, perpetratorization, and bystander situations.
Q. Is 5 seconds enough?
A. It's possible for screening purposes, and its reliability is high when repeated and trending data are considered.
Q. Is it a medical device?
A. No. It's classified as a life guidance and counseling aid.
