3. Importance of Dealing with Stress
BACKGROUND
Importance of Dealing with Stress
Can affect your body: Back Pain, Headaches, Lower Immune System
Can affect your emotions: Anger, Anxiety, Fatigue, Depression
Can affect your Behavior: Social Withdrawal, Affect Interpersonal Relationships, Poor Eating Habits, Substance Abuse

4. Purpose Detect stress Measure the strength of stress
Identify the things that trigger stress
Recommend techniques or programs to cope with the stress
Record the progress
- so that the stress can be avoided in the future

6. Existing Stress Detectors
Applications
Bulletproof Stress Detective by The Bulletproof Executive (iOS)
S Health by Samsung (Android)
Stress Check by Azumio (Both)
Devices
Tinké by Zensorium - Smartphone Compatible Monitor (Fitness and Stress) Measures Heart Rate Through Thumb
Inner Balance Sensor by HeartMath (Earlobe Clip Sensor, Heart Rate)
Bullet - Bluetooth Low Energy Heart Rate Monitors
S Health - record and analyze your daily activities and habits, now has Stress Detector
Stress Check - measuring your heart rate through the camera and light features to estimate stress level

7. Stress Check Interface

8. Criticisms on the existing apps
Most of them measure heart rate variability
the change in the interval between heartbeats
Some of them lack the capacity for data processing to measure heart rate variability accurately
No way to know whether a dip in variability is caused by stress or positive excitement
Stress caused by memories of past stressful events can be color the current mood

9. What’s different on our app?
Heart rate variability is still the most robust, noninvasive measures of stress response
when someone is in a distressing or scary situation, the autonomic nervous system activates the fight-or-flight response, which reduces the variability in the interval between heartbeats. A stressed-out heart, for instance, may only vary by two beats per breath cycle
Track the context of the person's situation to differentiate distressing events from exciting events
Time, place, season, weather, on vacation, on work, ...
Analyzes emotion from facial expressions
Context of situation - Time, place, season, weather, on vacation, on work, ...
