Goal

Develop notifications and alerts for the Moto 360 & Apple Watch for the Oscar Health app to detect

- collisions- pharmacies with unpicked up

prescriptions

Research

We defined our primary users usingUser Surveys, User Interviews& User Stories

We then Develop 3 Personas

Oscar Alert: Jean

JEAN

Female 27 Years OldFreelance CopywriterLives in Astoria, NY

Oberlin College GradHTC One Android Phone

Oscar Bronze

BEHAVIORS & HABITS

Likes to use Oscar to find pharmaciesLikes to use Oscar to check the last time she had a check-upLikes that Oscar app has an ID card in the appLikes that Oscar communicates clear copyChose Oscar from research because it is affordableAvid app user, uses her phone to find directionshas friends and a boyfriend that she likes to hang out and spend time withLikes that Oscar app gives her suggestions

GOAL

Continue to rely on Oscar app to deliver her medical needs

Needs to be able to find doctors and pharmacies quickly.

Save money

“In NYC there’s no strong concept of a primary care doctor, it feels really sketchy to find good care… does it cover my insurance? Who is this doctor etc. Oscar does a good job of clarifying and communicating.”

“I like how Oscar gives you suggestions on what you might need, if you have a headache, stomach pain… etc. It’s kind of like WebMD.”

Research

We researched the Moto 360 & Apple Watch technical specifications, looked at APIs and developed case studies

Case Studies

Collision Detection

OnStar / WreckWatch / Secura Patch Case Studies

Case Studies

(source: https://www.dre.vanderbilt.edu/~schmidt/PDF/wreckwatch.pdf)

In-vehicle Collision Detection // OnStar

Conventional in-vehicle accident detection systems (like OnStar) rely on sensor networks throughout the car and direct interaction with the vehicle’s electronic control units (ECUs). These sensors detect acceleration/deceleration, airbag deployment, and vehicular rollover.

Metrics from these sensors aid in generating a detailed accident profile, such as locating where the vehicle was struck, number of times it was hit, severity of the collision, and airbag deployment.

Case Studies

(source: https://www.dre.vanderbilt.edu/~schmidt/PDF/wreckwatch.pdf)

Wireless mobile sensor network can capture the streams of data provided by their accelerometers, compasses, and GPS sensors

Provide a portable “black box” that detects traffic accidents and records data related to accident events, such as the G-forces (accelerations) experienced by the driver.

Cellphone Collision Detection // WreckWatch

Background services detect accidents by polling smartphone system sensors, such as the GPS receiver and accelerometers.

Cellphone Collision Detection // WreckWatch

(source: https://www.dre.vanderbilt.edu/~schmidt/PDF/wreckwatch.pdf)

Case Studies

WreckWatch provides functionality similar to an accident/event data recorder by recording the path, speed, and forces of acceleration on a vehicle leading up to and during an accident.

WreckWatch is built using Google Android on the client and Java/MySQL with Jetty and the Spring Framework on the server.

The WreckWatch server utilizes custom XML and JSON to communicate with the client

Case Studies

Heart Rate Detection

Secura Patch Case Study

Heart Rate Monitor // SecuraPatch

(Sources: http://www.securafone.com/subpages/health.phphttp://www.eweek.com/mobile/securatrac-smartphone-app-connects-biosensor-patch-to-the-cloud)

Case Studies

SecuraPatch uses a small, wearable patch attached to a person’s chest or back, using bluetooth (low energy) technology to gathers and transmits data continuously to the “relay” (the SecuraFone mobile app)

Uses MEMS accelerometers (Micro Electro Mechanical Systems) & Cloud-based Computing (ReliaTrac® platform from SecuraTrac®)

The SecuraPatch is able to detect heart rate, respiration rate, falls, stress levels, skin temperature, activity or number of steps, caloric burn, and body posture

Smart Watch for Emergency Response // Challenges

Smartphone application that required interaction with an onboard computer would be useless in cars that lacked one.

It is therefore necessary to collect the same or similar information utilizing only the sensors present on the smartwatch / smartphone device.

Both do not have built in GPS, rely on smart phone for GPS

Uses AFE4490 pulseOx AFE to measure heart rate. Pedometer (9-axis sensor) includes 3-axis gyroscope (orientation), 3-axis accelerometer (g-force), 3-axis magnetometer (compass). Temperature sensor, and a light sensor.

Trouble with consistent read - needs viewer to be still in order to measure heart rate

While the watch does check heart rate in the background continuously. An ECG (electrocardiogram) test (usually used to detect heart abnormalities) usually requires much more information and areas of contact on the skin.

Apple Watch // Heart Rate Monitor Specs / Challenges

Challenges / Proposal

(sourcehttp://spectrum.ieee.org/view-from-the-valley/consumer-electronics/portable-devices/apple-watchs-wristful-of-sensors-and-mems, )

Uses pulse oximeters use visible red and infrared LEDs to detect how much oxygen is being carried in the blood’s hemoglobin — a red protein responsible for carrying oxygen from the lungs to all other tissues of the body. In this process, the oxygenated hemoglobin absorbs more infrared light

Apple chose the light-based technology over electrocardiography because it is considered to be a more accurate method to measure electrical impulses.

Most electrocardiogram (EKG or ECG) products require users to attach several diodes to their body or to touch the product with both hands in order to get a reading.

However, the light-based technology will monitor the user’s heart rate with the user just simply wearing the wristwatch.

Smart Watch for Emergency Response // Proposal

The combination of Smart Watch & Smart phone sensors may measure forces closer to those experienced by victims. In the event of an accident, the SmartWatch will experience close to the same forces and accelerations, as well as heart rate monitors experienced by the occupants of the vehicle.

If the smartphone remains stationary relative to the vehicle during the collision, it is possible to use the data gathered from the smartphone to recreate and model the forces it experienced. In this case, the combination of the two can provide data much like that gathered by vehicular ECUs

We can use these sensors to trigger an emergency response on the smartwatch

Smart Watch for Emergency Response // Proposal

Challenges / Proposal

While we may not be able to predict a heart attack, we can use the combination of the heart rate sensors and the other sensors to detect abnormal movement and Heart rate, thus triggering an emergency notification.

Challenges / Proposal

Smart Watch for Emergency Response

!SOS!

!

1) Impact detected with smart watch/smart phone & GPS

2) GPS & Heart rate monitor trigger emergency message on smart watch.

3) Oscar on-call doctor is notified through alert on smart watch (and transmitter via smart phone) as well as the closest emergency responder (as determined by GPS)

Communication is open between the channels.

Todoist is already integrated with Google Maps API, so it will detect which places you frequent the most, provided of course that you turn your location services on.

Context aware system - Using GPS technology for location-sensing, people could set reminders around certain locations, with given time constraints

Oscar Health Wearables // Next steps

● More user testing and iterations to test for interaction and flow

● Integrate Apple’s HealthKit and Google Fit with the wearable and Oscar Health App so that there’s a more detailed and accurate representation of a person’s health

● Maximize hardware capabilities with more APIs - what kind of symptoms can we detect with the heart rate sensor?

● Maximize the information about the user for emergency responder - pulling Oscar Health user past history, current medication, family history etc.

● Make it more accessible for those who have disabilities (visual/blind)
