This time, I installed it on iPhone 14 in advance. Since access to Bluetooth is required at the first startup, tap 'OK'.

Tap 'Start with setup'.

After understanding the contents of the software license agreement, avatar license agreement, and mocopi privacy policy, check all three and tap 'Agree'.

Prepare mocopi body and tap 'Next'.

From here, we will pair the six sensors one by one with the smartphone. For example, in the case of the HEAD sensor, it looks like this. Take out the sensor and press the switch in the middle.

Then, the serial number written on the back of the sensor is displayed on the iPhone screen, so confirm that it is the same.

After tapping the serial number and checking it, tap 'Next'.

Tap 'Next'.

Here, the sensor requests Bluetooth pairing to the iPhone, so tap 'Pairing'. This completes the pairing of the HEAD sensor and the iPhone. Do the same for WRIST (right), WRIST (left), HIP, ANKLE (right), and ANKLE (left).

When pairing is completed with all six sensors, the iPhone side will move to the 'Preparing for connection' screen. It's a little hard to understand in the image below, but confirm that the area around the button in the center of the sensor is blinking blue.

Tap 'Confirm'.

Tap 'Connect to sensor'.

When the connection with all sensors is completed, a check mark, battery status, and 'connected' notation are displayed, so tap 'Confirm'.

Prepare a band to fix the sensor. Tap 'Next'.

Tap 'Next'.

I attached sensors to all bands and fixtures like this.

Install the sensors in the following positions. Tap 'Confirm'.

The place where the sensor is actually installed is like this. In the image below, the HEAD sensor and ANKLE sensor are attached to the front, but the manufacturer's recommendation is to attach the HEAD sensor to the rear and the ANKLE sensor to the outside.

HIP is worn by tucking the clip into the pants.

Calibrate. Select the height of the wearer and tap 'Next'.

Take the basic posture and perform calibration. When doing this calibration, if you place your smartphone on the desk, the moment you tap it, the initial basic posture will inevitably collapse and you will fail. Therefore, it is good to grasp the position to tap with the smartphone in hand in advance, take the basic posture, and then tap 'Start calibration'.

If the calibration is successful, it will move to the main capture screen as shown below. Tap 'Next'.

Tap 'OK'.

Setup is now complete. The sensor needs to be paired and registered for the first time, but it didn't require any complicated operations, and it finished quickly in about 30 minutes. The image in the center of the capture screen is RAYNOS, the official avatar preset in the

Next, we plan to actually perform motion capture and check its accuracy, so please look forward to it. Mocopi is scheduled to appear on January 20, 2023, and the price is 49,500 yen including tax.
