(2) Applicable Hardware Model:
- 'EOT Ware Co,. Ltd' (model name: EOT-VANZI-V1).
- No models applied other than the above products
(3) Function summary: Measures blood pressure, heart rate, oxygen saturation, body temperature, and activity level in real time and periodically using a dedicated wearable device, and transmits/stores this to the smartphone through 'Bluetooth Low Energy' communication method. It always displays numbers and graphs, allowing users to easily monitor changes in their health status.
(4) Screen page composition: Composed of 5 pages: ‘Current status’, ‘View changes’, ‘Input information’, ‘Notification settings’, and ‘Ring registration’ (see image)
(4.1) 'Current status' page:
- Displays the most recently measured body temperature, activity level, oxygen saturation, blood pressure, heart rate, and heart rate variability in numerical values.
- The operating status of the wearable device is displayed as an icon in the upper right corner of the screen.
- Perform real-time measurement using the ‘Measure’ button
- Select measurement cycle
- Information about the time of the synchronized ring, ring registration date and time, and number of measurements is displayed at the bottom of the screen.
- There is a button at the bottom of the screen to move to another page.
(4.2) ‘View changes’ page:
- Changes over time of 5 types of measurement data stored in the database are displayed as graphs.
- Click the left and right arrows at the bottom of the screen to check the data value at the desired time.
(4.3) ‘Information input’ screen:
- Body temperature: Enter the user’s core body temperature measured with a separate standard thermometer (for body temperature correction)
- Blood pressure: Enter manual and diastolic blood pressure measured with a standard blood pressure monitor (for blood pressure correction)
- User ID: Enter an identification consisting of 6 characters (to match the smartphone and wearable device 1 to 1)
(4.4) ‘Notification Settings’ page:
- Alarm level settings for 5 types of measurements
- Set sound when notification occurs

(5) Main operation concepts
- The smartphone app VanziOn and wearable devices are matched 1:1 using the registered ID and MAC address to distinguish them from other wearable devices or other smartphones.
- When registering, you must wear a wearable device and be close to your smartphone for 1:1 matching.
- When using a wearable device during long-term activities, wear the provided band.
- Registration and measurement possible only when wearing a wearable device
- After registration, if you are wearing the wearable device, measurements are performed according to the set cycle (default 2 hours)
- When handing over a wearable device to someone else (changing it to another smartphone), you must execute ‘Delete’ and re-register.
- Measurements are possible even while the wearable device is charging.
