Preparing recording observations… All recorded board inputs; chest + hip for shock candidates. Separate from 3D sensor selection. Not confirmed tricks. Sensor-clock times; click to review.

Board orientation and travel direction are calculated separately.

Default rider stance

Adjust the chest and arms' starting pose. Sensor movement continues; board and feet stay fixed. These are visual offsets, not calibration. Forward / back · X 0° Side lean · Z 0° Chest turn · Y 0° Rider rotation · hips + upper body 0° Rider rotation turns the hips and upper body together. The legs fit back to the fixed boots; joint limits can reduce the turn. Centre = zero offset. Positive and negative values move in opposite directions. Joint limits still apply.

Head

Visual head correction only. Does not change the recorded sensor data.Forward / back tilt 0°Turn left / right 0°Side tilt 0°

Left arm

Left arm starting pose only. The recorded left-arm movement continues. Swing · X 0° Rotate · Y 0° Raise / lower · Z 0°

Right arm

Right arm starting pose only. The recorded right-arm movement continues. Swing · X 0° Rotate · Y 0° Raise / lower · Z 0°

Open chest + natural arm stance Hold base pose still (pause body sensor movement)

Model offsets only. Save as default for all recordings.

Choose a frame that matches your base stance. Changes the relative model reference for this run only, not sensor calibration. Direct sensor rotations Keep boots attached (fit legs) Direct upper-body rotations bypass upright and joint limits. With attached boots, hips and legs are fitted; body positions remain estimated.

Sensor directions & calibration

Waiting for recording

Device R/P/Y are not joint angles. Board axes: X across the board, Y up, Z toward the nose. Direction changes are not distances. Inspect selected sensor Use this body sensor Show requested / model axes Long, faint axes = requested direction. Short, bright axes = modeled direction. Red X · green Y · blue Z. Estimated axes are not proven anatomical directions.

Calibrate from a recorded drill

Use a separate calibration section: board flat and still, neutral body pose, then hold each forward position for one second. Return to neutral between repetitions. The calibration reference uses shoulders open 15° toward the board nose. In Default rider stance, Reset stance and then turn off “Open chest + natural arm stance” to remove visual rest offsets. A natural riding pose is not automatically this reference pose. Enter seconds relative to the run start (negative values can use pre-run data). Video is for verification only. Neutral hold Forward hold Repeated forward hold I know these were recorded calibration movements and the mounting matches the selected segment—not poses guessed from the video.
