Quick Start Guide for the hBAND Watch

What You Need

  • MAX-HEALTH-BAND (hBAND) fitness watch
  • Android® device (e.g., phone, tablet, etc.) with Bluetooth® connection for data logging
  • micro-USB type-B cable (provided) for charging

Power On/Off and Wearing
During the first few seconds after powering on the watch, the watch sensor (the surface that normally faces the wrist when worn) should be off the wrist and exposed to ambient air. This is required for proximity detection and for the algorithm to work properly.

  1. To turn on the watch, hold the watch with the sensor surface exposed to ambient air and press the button down for two seconds. The watch vibrates and an hBAND logo appears after a few seconds. The watch is ready to be worn on the wrist as soon as the logo appears.
  2. After the hBAND logo appears, position the device approximately one finger width up the arm from the wrist bone (see figure below). If possible, wear the watch on the non-dominant hand, as this improves the quality of the data. The watch should fit tightly but comfortably around the wrist.

    Watch placed approximately one finger width above the wrist bone. Figure 1. Watch placed approximately one finger width above the wrist bone.

  3. To power off or reboot the watch, press the button down for 10 seconds. A power-off warning sign () is displayed before the watch powers off. Hold the button until the warning sign disappears to ensure that the watch is powered off.

NOTE: After powering up and placing the watch on the wrist, it can take up to one minute for the algorithm to initially report a heart rate value. In the interim, the display shows a short line ("-").

NOTE: If the watch is powered on or power-cycled while being worn on the wrist, lift the watch one inch away from the wrist surface for more than one second; this updates the proximity setting without you needing to completely take off the watch. This can be done at any time (e.g., during any operation mode, and even during data logging). During the process, be sure not to insert fingers in the one-inch clearance space between the watch and the skin. Make sure the strap is tightly fitted around the wrist afterwards.

Low Battery/Charging
The watch has a screen showing remaining battery life. Currently, the device does not have a warning for low battery.

The watch can be recharged using a micro-USB type-B cable (provided). When connecting the watch to a charger, the device vibrates and displays a recharging screen. Removing the watch from the charger will causes the device to vibrate.

Modes
The watch has the following modes: sampled mode and continuous mode. The operating mode can be changed from the watch by pressing the button down for one second. The watch vibrates as an indicator of mode change.

Sampled Mode
The watch is in sampled mode by default. In this mode, the device measures the heart rate every five minutes or whenever the button is pressed. Sampled mode display items are shown in the figure below.

Sampled mode display. Figure 2. Sampled mode display.

Continuous Mode
In continuous mode, photoplethysmogram (PPG) and acceleration are sampled constantly at 100Hz and averaged over four samples. Heart rate (HR) is estimated once per second. In addition, a small heart is shown in the display's upper-left corner while the device is in continuous mode. Continuous mode display items are shown below.

Continuous mode display. Figure 3. Continuous mode display.

Heart Rate Display in Both Modes
The following heart rate display items appear in both sampled mode and continuous mode.

Heart rate display. Figure 4. Heart rate display.

Health Map App

For data logging, the user must install the provided Health Map app for Android.

To ensure uninterrupted data logging and watch connection, change the display setting of the Android phone or tablet to keep screen always ON before running the app.

Installing the App
To install the Health Map app:

  1. Save the provided .apk-file to a location that you can access by phone (for example, to the phone memory if you have a file browser or to Dropbox®). Accessing the file prompts the user to install the app.
  2. If the app detects that the firmware is outdated, you can upgrade the firmware.
  3. Grant permission when the app asks for access to the files on the phone and the location. These are required for the Bluetooth connection to work.

Connecting to an hBAND Watch
The app's initial start-up screen is blank with a SCAN button at the top right corner.

To connect the Health Map app to an hBAND device:

  1. Press the SCAN button in the top right corner to bring up a list of available devices in range.
  2. Select the name of the sample device, hBAND.

The main screen (see figure below) is displayed after a successful connection.

Health Map main screen. Figure 5. Health Map main screen.

Collecting Data
The watch can measure both optical count and HR. By saving data to a database, users can access the raw optical count, computed HR based on an internal algorithm, and other information.

To start data collection:

  1. Press the three dots in the upper right corner to bring up a pop-up menu (see figure below).

    Pop-up menu. Figure 6. Pop-up menu.

  2. Select Continuous mode for a fast sampling rate.
  3. Select either RAW or HR+RAW. Both RAW and HR+RAW export identical data to the database. When HR+RAW is selected, however, the heart rate value is also displayed on the phone display screen in real time.

The Raw Data icon on the main screen is automatically turned to ON.

Data is now being stored in the device memory. As long as the Bluetooth connection remains, data is transferred (and deleted) from the watch memory to the phone database. If the Bluetooth connection is interrupted while data is being collected in the device memory, new data is not lost, but is streamed to the phone as soon as the Bluetooth connection is reestablished.

NOTE: Raw data refers to the optical and accelerometer data before it is fed through an internal algorithm.

To stop data collection:

  1. Press the three dots in the upper right corner to bring out a pop-up menu.
  2. To stop saving data to database, select HR. The RAW DATA icon status is changed to OFF.

Viewing Real-Time Data
To see real-time charting of raw data:

  1. Return to the main screen.
  2. Select the RAW DATA icon in the main screen. A new charting window opens (see figure below).

Real-time charting window. Figure 7. Real-time charting window.

To close the charting window:

  1. Select the Back button on the Android device.
  2. Close the charting window and return to the main screen as soon as visualization of data is no longer required.

NOTE: When the charting window is open, data is stored locally on the watch, but it is not streamed to or synchronized with the database on the phone until the charting window is closed. To ensure proper saving of data to the database, exit the real-time charting window and return to the main screen promptly after validation is complete.

Exporting Real-Time Data
The user can export, or copy, the SQLITE database to a .csv file. When exporting, the original data remains in the SQLITE database, and newly collected data is appended to it. Subsequent exports of database data into .csv files contains both previous and new data. Therefore, when starting a new study, it is recommended that the user clears the database by deleting the SQLITE files before data acquisition. New SQLITE files are created automatically in the next data-logging session.

To export data to .csv format for analysis:

  1. Press the three dots in the upper right corner of the main screen.
  2. Select Export DB.

For more details regarding the output file format, see the "hBAND User's Guide."
