Detailed Description

Contains information about position and tracking of the hand

Field Documentation

amount_of_contour_points

int TrackingInfo.amount_of_contour_points

Deprecated:

bounding_box

BoundingBox TrackingInfo.bounding_box

Provides tracking information regarding the bounding box that contains the hand.

it yields normalized values between 0..1

contour_points

Vector3 [] TrackingInfo.contour_points

Deprecated:

depth_estimation

float TrackingInfo.depth_estimation

Provides tracking information regarding an estimation of the hand depth.

it yields a 0-1 float value depending based on the distance of the hand from the camera.

Example

private float depthValue;
private float maxDepth = 0.8f;
 
// <summary>
// Runs every frame, gets the float value of the depth_estimation.
// </summary>
void Update()
{
    depthValue = ManomotionManager.Instance.Hand_infos[0].hand_info.tracking_info.depth_estimation;
    CheckDepth(depthValue);
}
 
// <summary>
// Checks if current depth is greater than our maxDepth value, if so the phone will vibrate
// </summary>
// <param name="depth">the current depthValue from depth_estimation</param>
void CheckDepth(float depth)
{
    if (depth > maxDepth)
    {
        // Your code here
        Handheld.Vibrate();
    }
}

finger_tips

Vector3 [] TrackingInfo.finger_tips

Deprecated:

palm_center

Vector3 TrackingInfo.palm_center

Provides tracking information regarding the bounding box center that contains the hand, this information is primarily used in the cursor gizmo.

it yields a normalized Vector3 information with the depth being 0 at the moment. a temporary solution would be to combine it with the depth estimation value (see below).

Example

private Vector3 trackedPosition;
float screenRightSideXValue = 0.5f;
 
// <summary>
// Runs every frame, gets the position of the palm_center.
// </summary>
void Update()
{
    trackedPosition = ManomotionManager.Instance.Hand_infos[0].hand_info.tracking_info.palm_center;
    TrackedHandPosition(trackedPosition);
}
 
// <summary>
// When the tracked hand position is on the right side of the screen, and x is greater than
// 0.5f the code will be executed. In this case the phone will vibrate.
// </summary>
// <param name="trackedPosition">the Vector3 from the palm center of the hand that's being
// tracked</param>
void TrackedHandPosition(Vector3 trackedPosition)
{
    if (trackedPosition.x > screenRightSideXValue)
    {
        // Your code here.
        Handheld.Vibrate();
    }
}

poi

Vector3 TrackingInfo.poi

Deprecated:

rotation

float TrackingInfo.rotation

Deprecated:

skeleton

SkeletonInfo TrackingInfo.skeleton

Contains the positions of the 21 joints

wristInfo

WristInfo TrackingInfo.wristInfo

Deprecated:
