MOBILE PHONE SENSORS IN HEALTH APPLICATIONS Evgeny Stankevich, Llya Paramonov, Ivan Tomofeev Demidov Yaroslavl State University Presented By Brian K. Gervais 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 QUESTIONS
