How to measure
Move from device discovery to Datahub upload in five steps
Follow the actual mobile screens to connect EmoConnect, save a PPG and IMU session, and upload it to Datahub.
Before you start · Check these four items before measuring
Prepare the device, app, Bluetooth permission, and study details before starting the measurement.
EmoConnect device
Charge and power on the device, then keep it close to the measurement host.
Target environment
Confirm the EmoConnect PPG&Motion app or SDK product for your operating system.
Bluetooth permission
Enable Bluetooth and allow the nearby-device permissions required by the operating system.
Study and participant details
Load an existing study or create one, then enter participant and event details.
- STEP 1
Search for an EmoConnect device
Enable Bluetooth and nearby-device permission, then open the device-connection screen. Keep EmoConnect near the phone while the app searches.
- Confirm that EmoConnect is powered and charged
- Allow Bluetooth and nearby-device permission
- Refresh if the search does not complete
Search for nearby EmoConnect devices from the connection screen. - STEP 2
Select and connect the target device
Check the EmoConnect name in the result list, then select the device assigned to the session. Recheck the assignment when several devices are nearby.
- Match the device name to the assignment
- Select the target EmoConnect card
- Confirm that the app moves to the measurement screen
Device IDs are redacted. Choose the EmoConnect assigned to the study. - STEP 3
Measure PPG and IMU and save the session
Review the study and participant details in the measurement tab, start measurement, and record configured events. The completed session appears in Saved Data after stopping.
- Review study and participant details
- Record configured events during measurement
- Confirm the saved entry and duration after stopping
Fictional sessions are shown only to explain the list layout. They are not actual measurements. - STEP 4
Review the saved session details
Open the saved-data menu and review the study name, participant identifier, entered participant details, duration, and file-creation date.
- Confirm the study and participant identifier
- Review duration and creation date
- Match the session before uploading
Review study, participant, and timing information before upload. - STEP 5
DATAHUB Upload
Select the cloud icon for the saved session. The app opens a confirmation dialog showing the destination study; verify it, then upload the data.
- Select the cloud icon for the session
- Match the destination DATAHUB study in the dialog
