Mobile smart devices are becoming increasingly sophisticated. The latest generation of smart
cell phones now incorporates many diverse and powerful smart sensors
Friday, August 12, 2016
 GPS (Geographical position system ) sensor
 Magnetometer sensor
 Gyro meter sensor
 light sensor
 Temperature sensor
 Direction sensor
 Orientation sensor
the latest wearable sensors called mobile health (mHealth)
sensors for health related activities measurements and basic
vital sign of human. Deployment of these diverse mHealth
sensors at different spatial locations on human body sets up
human activity environment where different human activities
recorded and measured can be used for Human Activity
Recognition (HAR) for all basic function of human
(VITAL SIGN).

WHAT IS mHealth..?
 mHealth is the use of mobile and wireless
technologies, such as mobile phones, patient
monitoring devices, personal digital assistants,
and mobile software applications (apps),to
support the achievement of health objectives
 The adoption of mHealth seeks to take
advantage of the explosion in mobile devices
available worldwide

mHealth Applications and Benefits
The United Nations has identified seven application categories within the mHealth field, including:
 Remote monitoring
 Remote data collection
 Education and awareness
 Diagnostic and treatment support
 Disease and epidemic outbreak tracking
 Helpline
Benefits include the ability to:
 Access healthcare information.
 Diagnose & track disease.
 Gather actionable public information.
 Deliver medical education & training

What is physical activity?
Physical activity simply means movement of the body that uses energy.
 Climbing Stairs,
 Cycling,
 Front elevation of arm
 Jogging, jump front andBack
 Knee bending
 Lying down
 Running, Sitting & relaxing
 Standing still
 Waist bend forward,
 Walking.

Activity recognition in health field

Physical activity is important for everyone, but how much you need
depends on your age.
ADULTS (18-60 YEARS):

2. CHILDREN AND ADOLESCENTS (6-17 YEARS)
 Most of the 60 minutes should be either
moderate- or Vigorous intensity aerobic physical activity,
 Should include vigorous-intensity physical activity at least
3 days a week.
 Children and adolescents should do 60 minutes
3. YOUNG CHILDREN (2-5 YEARS)
 There is not a specific recommendation for the number of
minutes young children should be active each day.
 Children ages 2-5 years should play actively several times
each day.
 Their activity may happen in short bursts of time and not
be all at once.
 Physical activities for young children should be
developmentally appropriate, fun, and offer variety

6. Research Methodology

DATA SCIENCE APPROACH FOR FOR HUMAN ACTIVITY RECOGNITION & VITAL SIGN
PREDICTTIONS

 The MHEALTH (Mobile HEALTH) dataset comprises Physical
activities and vital signs
 Recordings for ten volunteers of diverse profile while
performing several physical activities.
 Sensors placed on the subject's chest, right wrist and left
ankle are used to measure the motion experienced by
diverse body parts,
 namely, the acceleration, the rate of turn and the magnetic
field orientation.
 The sensor positioned on the chest also provides 2-lead ECG
measurements, which can be potentially used for basic heart
monitoring, checking for various arrhythmias or looking at
the effects of exercise on the ECG.
