5. Monitoring Zone Resting mode:
An app assesses the reading from the pulse sensors .
Notifies users and surroundings with beeps of high or low BPM.
Contacts a caregiver when pulse is above/below the normal.
Accelerometer of the phone on X, Y, Z are approximately 0.
Active Zone:
Phone’s accelerometer reading are > 0 ; Not stationary.
Assessment of BPM is discarded.
Buzzer notifies only for heat alert
Normalization of HR:
Transition from Active -> Resting modes.
Wait for user to normalize his/her heart rate.
Time Period is 5 sec (Recommended a few minutes)
