Charging Case

The Perception Neuron Pro case is also called Charging case. The case is muliti-use, for Charging and calibrating sensors.

PN Pro Sensors

The PN Pro's sensors are wireless MEMS inertial sensors with gyroscope, accelerometer, and magnetometer integration. There are 17 + 1 spare. Each of them is assigned a specific part of the body which is shown on the back of each sensor. Remember to charge them before use. The battery life is about 3 ½ hrs. and a full charge takes about 1 hr.

Turn on the PN Pro Sensors

  • Method 1: Unplugging the charging cable from the charging case will turn on all the sensors.
  • Method 2: Press the button on top of the sensor for about 2s to turn on the sensor. Press the button for about 5s to turn off the sensor.

LED Light Status Description

  • Slow Blink: The sensor is in standby mode to save the power
  • Fast Blink: The sensor is in working mode, calculating the transfer of data
  • Solid light: There is magnetic interference in the environment near the sensor
  • Red light: The sensor has low battery or is charging.
  • Green light: The sensor is in channel 1
  • Blue light: The sensor is in channel 2
  • Yellow light: The sensor is in channel 3

PN Pro Hub

The PN Pro hub relays data between the PN Pro sensors and Axis Neuron Pro

2.Charge Sensors

Make sure that you have all the required hardware and charge the sensors.

  • Connect the power adapter to the charging case, make sure all LEDs are red.
  • When a sensor is fully charged, the red LED will turn off automatically.

2. Download and Install Axis Neuron Pro

  • Connect the hub to your computer via USB. 
  • Turn on the sensors, then click Connect in Axis Neuron Pro.

4. Sensor Calibration

Before placing the sensors on the actor, perform a COMPASS CALIBRATION procedure.

  • Turn on the sensors and connect them to Axis Neuron Pro 
  • Click on posture calibration
  • Lift the Calibration box and tilt it gently, all the bones on the avatar should move in the same direction.

If the bones do not all move in the same direction, or you notice drift, it is time to run a compass calibration on the sensors.

  • To do this, go to Tool → Compass calibration
  • Follow the video guide to see how to properly rotate the sensor charging case.
  • If you continue to have problems, you may need to calibrate the sensors individually.  To do this, only turn on the sensor you wish to calibrate, run the Compass calibration, and roll the sensor in your hand like cookie dough.

5. Strap and Sensor Placement

  • Put on the body straps

  • Put sensors onto the body straps by connecting them to the sockets.
  • After placing the sensors in the sockets, rotate them 90 degrees clockwise.  You should hear a click.

6. Posture Calibration

After the sensors are on your actor, it's time to run a posture calibration.

  • First, select a body size template based on your performer's height.  You can adjust other measurements as well for a more accurate capture.
  • Click Posture Calibration to perform the three step (A,T,S) posture calibration.

Now you are ready to record!
