ABSTRACT
• By 2015 the WHOLE WORLD will be covered by
Cellular networks
• ½ population will use a mobile phone
• GSM
• Wifi
• Bluetooth
• mHealth- “Practical medicine and healthcare
services supported by mobile devices”
• Growing Fast
ABSTRACT
• mHealth apps increase availability of healthcare
solutions
• App Store, Google Play, Ovi Store
• Modern phone equipped with powerful
embedded sensors
• Microphone
• Accelerometers
• Camera
• Light sensors
MOBILE PHONE
SENSORS
• Two Categories
• Environment
•
Microphone, camera
• Position
•
Accelerometers, digital compass, gyroscope,
and GPS
MOBILE PHONE
SENSORS
•
Microphone
• Used to determine activity
•
•
•
•
•
Speaking, café visiting, car driving
Light sensor
• Measures ambient light
Proximity Sensor
• detects presence of nearby objects
Accelerometers and magnetometers
• Phone orientation has been applied to games
Gyroscope/GPS – used for navigation
MHEALTH
•
How are these sensors used for healthcare apps
• Microphone
•
•
•
Communication
Disease and epidemic outbreak tracking
Diagnosis and treatment support
•
•
•
Myotonia disorder
• Patients called automated voice to classify
symptoms.
• If needed they would be referred to doctor
Reduces unnecessary doctors visits
Decreasing healthcare cost
MHEALTH
•
Camera
• Provide images and video for remote doctor
consultation.
• Teledermatology- is where patient skin images are
used by doctors to make diagnosis
•
ClickMedix
•
•
•
Patient registers and receives training on proper photos
Photos sent to data collection server and doctor
prescribes treatment
Good for developing countries
•
•
•
Lack of access
Lack of funds
Lack of medical resources
MHEALTH
•
Camera
• Telconsultation and diagnosis of soft tissue injuries
• Detect heart rate using skin color analysis
•
•
Digital filter to detect heart rate by analyzing
video of face (pulse oximeters)
•
•
Instant Heart Rate application- IOS/Android
Cardiio application- IOS
These do not require extra equipment
•
Cheap readily available
MHEALTH
•
Camera w/additional equipment
• Create light microscope
•
•
•
•
Uses the phone camera
Researchers determine that modern camera
phones have sufficient resolution to detect blood
cells and microorganism morphology.
Such system cheap and portable and can detect
TB
Operators do not have to be well trained
•
Images fed to doctors at separate locations
ACCELEROMETER
SENSOR AND GEO.
•
•
Track persons physical activity level
• Reduce risk of many chronic diseases
Goes beyond pedometers
• No need for additional device
• Through analyzing the data you can determine
•
•
Walking/Biking/Running
Give calorie count and provide feedback to the
patient
ACCELEROMETER
SENSOR AND GEO.
•
Fall detection
• Brickhouse- current solution
•
•
Requires base station and only works at that
location
Phone could do all that and more
•
•
•
•
Measure whether fall has occurred
Alert authorities
Give them an accurate location
No need for external devices
ACCELEROMETER
SENSOR AND GEO.
•
Rehabilitation
• m-Physio
•
•
•
Reduces need to go to rehabilitation center
Patients first sessions are used to train sensors and
patient
Phone then used to tell patient/Doctor
•
Duration/Quality of exercises from home
CONCLUSION
• Overall theme- reduce cost and increase access to
healthcare
• Phones are out there use them to do more
than Facebook
• These purposed apps and the future apps will
greatly increase health in poor countries
where access to medical treatment is minimal
