When creating a project, you have the option of selecting which pieces of passive sensor data you would like to collect via the MyDataHelps app.
Enabling Sensor Data Collection
To enable sensor data collection for your project:
- Go to the "Projects" screen and select the "Sensor Data" tab.
- Select a sensor data collection service (e.g. Apple Health, Google Fit, etc.).
- Select one or more data types to collect.
- Click "Save Sensor Data Settings" to save your changes. You can also click "Revert Changes" to undo your changes.
The tabs on the left will tell you how many data types for each service are being collected. You can collect data from multiple services in the same project.
You don't need to deliver surveys in order to collect sensor data. It is collected passively in the background as long as the user is enrolled in your project and has enabled the appropriate permissions.
Sensor Collection Limitations
When the participant enrolls in a project, they will be prompted to enable sharing of the data types you have enabled. The app will prompt the participant again if you enable different permissions.
When reviewing project data, you can see what data has been collected for a participant in the Participant Viewer. It is not possible to distinguish whether a user has declined to share data or the data is simply unavailable.
If the user has elected to share sensor data, MyDataHelps will collect data passively--even when the participant is not using the app.
See the specific sensor data service sections below for more information about how MyDataHelps collects sensor data.
On iOS devices, MyDataHelps can collect data from Apple Health. Apple Health supports a number of different data types: activity, vital signs, sleep analysis, body measurements, and clinical records, nutrition and more.
When the participant enrolls in the project, the phone will ask them which sensor data they want to share. They can elect to share some, all, or none of the requested data.
If the participant has linked Apple Health to their provider's Electronic Medical Record system (EMR), your project can also collect selected medical records such as allergies and lab results.
Only the selected clinical data will be made available to RKStudio. RKStudio does not collect full medical records.
Apple Location Tracking
On iOS devices, MyDataHelps can track the participant's location. Apple's location tracking service operates in a power-efficient manner, with little to no impact on battery life.
When the participant enrolls in the project, the phone will ask them whether they want to allow MyDataHelps to collect location data.
There is no way to get location data for any time period while the MyDataHelps app wasn't installed or when the user had disabled location services.
On Android devices, MyDataHelps can retrieve health information from Google Fit, including heart rate, weight, and steps. The participant does not need to have the Google Fit app installed for MyDataHelps to collect data from Google Fit.
When the participant enrolls in the project, the phone will ask them which sensor data they want to share. They can elect to share some, all, or none of the requested data. The user will also be prompted to select which account they wish to use.
If the user has elected to share sensor data, MyDataHelps can collect data passively--even when the participant is not using the app.
Apple Movement Disorder Monitoring
For participants with the Apple Watch, MyDataHelps can use Apple's Movement Disorder Monitoring to track tremors and dyskinesia sensor data at 1-minute intervals.
Movement Disorder Monitoring is only for use in projects specifically related to Parkinson's disease or other movement disorders.
