LEAP_VECTOR position

The center position of the palm in millimeters from the Ultraleap Tracking camera device origin.

Since

3.0.0

LEAP_VECTOR stabilized_position

The time-filtered and stabilized position of the palm.

Smoothing and stabilization is performed in order to make this value more suitable for interaction with 2D content. The stabilized position lags behind the palm position by a variable amount, depending primarily on the speed of movement.

Since

3.0.0

LEAP_VECTOR velocity

The rate of change of the palm position in millimeters per second.

Since

3.0.0

LEAP_VECTOR normal

The normal vector to the palm.

If your hand is flat, this vector will point downward, or “out” of the front surface of your palm.

Since

3.0.0

float width

The estimated width of the palm when the hand is in a flat position.

Since

3.0.0

LEAP_VECTOR direction

The unit direction vector pointing from the palm position toward the fingers.

Since

3.0.0

LEAP_QUATERNION orientation

The quaternion representing the palm’s orientation corresponding to the basis {normal x direction, -normal, -direction}.
