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• Instant Heart Rate application- IOS/Android

• Digital filter to detect heart rate by analyzing video of face (pulse oximeters)• 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
