 Typically a user does not need to know anything about OpenXR to use the plugin, so this section of the handbook is for advanced users who are looking for a way to directly consume the OpenXR data coming directly from either a SenseGlove device or if enabled in the plugin settings from hand-tracking.
-Since the SenseGlove Unreal Engine Plugin registers itself as an `OpenXRHandTracking` motion controller device it becomes a hand-tracking provider for Unreal Engine, thus the OpenXR data from SenseGlove could always be retrieved from the Unreal Engine's `IXTrackingSystem` with one caveat.

Thus, SenseGlove provides its own implementation of `GetMotionControllerData()` which guarantees the retrieved `FXRMotionControllerData` is coming from the SenseGlove Unreal Engine Plugin; and this is the preferred way to that.

 Taking a closer look at the `FXRHandTrackingState` declaration inside the Unreal Engine's `HeadMountedDisplay` module at `[Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h](https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h)`, figuring out the data structure might not seem very straightforward:
 ```cpp
 USTRUCT(BlueprintType)
 struct FXRHandTrackingState
 {
    GENERATED_USTRUCT_BODY();
    // The state is valid if poses have ever been provided.
    UPROPERTY(BlueprintReadOnly, Category = "XR")

    EXRSpaceType XRSpaceType = EXRSpaceType::UnrealWorldSpace;
    UPROPERTY(BlueprintReadOnly, Category = "XR")
    EControllerHand Hand = EControllerHand::Left;
    UPROPERTY(BlueprintReadOnly, Category = "XR")

 But, fear not, we've got you covered!
 ## FXRHandTrackingState in Unreal Engine
 `FXRHandTrackingState` is a structure in Unreal Engine designed to hold detailed information about the state of a hand-tracking device at a given moment. This structure is essential for handling hand-tracking inputs in virtual reality (VR) applications, providing the necessary data to accurately track and represent the user's hand movements and actions within the virtual environment.
 ### Structure Members of FXRHandTrackingState
 - **bValid**
   - **Description**: A boolean flag indicating whether the data is valid or not.
   - **Usage**: This is used to check if the motion controller data is correctly initialized and can be used for further processing.
 - **DeviceName**
   - **Type**: `FName`
   - **Description**: The name of the device.
   - **Usage**: Identifies which device the data is coming from, useful when multiple devices are in use.
 - **ApplicationInstanceID**
   - **Type**: `FString`
   - **Description**: A unique identifier for the application instance.
   - **Usage**: Helps in differentiating data from different instances of an application, ensuring the correct instance processes the data.
 - **XRSpaceType**
   - **Type**: `EXRSpaceType`
   - **Description**: Enum specifying the type of XR space being used (e.g., unreal world or tracking space).
   - **Usage**: Specifies the coordinate system the XR Device is tracking itself in.
 - **Hand**
   - **Type**: `EControllerHand`
   - **Description**: Enum indicating which hand is being tracked (left or right).
   - **Usage**: Helps identify whether the hand-tracking data pertains to the left or right hand, essential for hand-specific actions or interactions.
 - **TrackingStatus**
   - **Type**: `EXRTrackingStatus`
   - **Description**: Enum indicating the tracking status of the hand-tracking device.
   - **Usage**: Shows whether the hand-tracking device is being tracked accurately, with possible statuses like `Tracked`, `NotTracked`, etc.
 - **HandKeyLocations**
   - **Type**: `TArray<FVector>`
   - **Description**: An array of vectors representing key locations of the hand.
   - **Usage**: Provides detailed locations of key points on the hand, useful for precise hand-tracking and interaction.
 - **HandKeyRotations**
    - **Type**: `TArray<FQuat>`
    - **Description**: An array of quaternions representing key rotations of the hand.
    - **Usage**: Complements the hand key locations with rotational data, ensuring accurate representation of hand movements.
 - **HandKeyRadii**
    - **Type**: `TArray<float>`
    - **Description**: An array of floats representing the radii of key points of the hand.
    - **Usage**: Gives the size of the hand key points, aiding in collision detection and interaction fidelity.
 ### Organization of FXRHandTrackingState
 The structure is organized to encapsulate all relevant data needed for hand-tracking in a coherent and accessible manner. Boolean flag `bValid` provides quick checks on the state of the controller data. Identifiers `DeviceName` and `ApplicationInstanceID` ensure the correct association of data. Arrays `HandKeyLocations`, `HandKeyRotations`, and `HandKeyRadii` allow detailed hand-tracking, which is critical for immersive VR experiences. Lastly, the tracking status `TrackingStatus` informs the system of the reliability of the data being processed and whether the hands are actively being tracked or they are inactive at the moment.
 ### Processing the Data for Drawing and Animating a Virtual Hand
 In order to draw and animate a virtual hand in real-time whether the data is coming from hand-tracking or a SenseGlove device, we could consume the data from the `HandKeyLocations` and `HandKeyRotations` fields of the `FXRHandTrackingState` struct.
 Both `HandKeyLocations` and `HandKeyRotations` contain 26 elements as defined by OpenXR's [`XR_HAND_JOINT_COUNT_EXT`](https://registry.khronos.org/OpenXR/specs/1.1/man/html/XR_HAND_JOINT_COUNT_EXT.html) and [`XrHandJointLocationsEXT`](https://registry.khronos.org/OpenXR/specs/1.0/man/html/XrHandJointLocationsEXT.html), etc.
 Unreal Engine also provides an enum called `EHandKeypoint` naming the 26 joints, and the equivalent of `XR_HAND_JOINT_COUNT_EXT` as `EHandKeypointCount` inside `[Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h](https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h)` as follows:
 ```cpp
 /**
 * Transforms that are tracked on the hand.
 * Matches the enums from WMR to make it a direct mapping
 */
 UENUM(BlueprintType)
 enum class EHandKeypoint : uint8
 {
    Palm,
    Wrist,
    ThumbMetacarpal,
    ThumbProximal,
    ThumbDistal,
    ThumbTip,
    IndexMetacarpal,
    IndexProximal,
    IndexIntermediate,
    IndexDistal,
    IndexTip,
    MiddleMetacarpal,
    MiddleProximal,
    MiddleIntermediate,
    MiddleDistal,
    MiddleTip,
    RingMetacarpal,
    RingProximal,
    RingIntermediate,
    RingDistal,
    RingTip,
    LittleMetacarpal,
    LittleProximal,
    LittleIntermediate,
    LittleDistal,
    LittleTip
 };
 const int32 EHandKeypointCount = static_cast<int32>(EHandKeypoint::LittleTip) + 1;
 ```
 So, getting the any joint's location or rotation is as easy as casting the enum value and passing it as the array index.
 ```cpp
    FXRHandTrackingState HandTrackingState;
    const bool bGotHandTrackingState = FSGXRTracker::GetHandTrackingState(
        GetWorld(), EXRSpaceType::UnrealWorldSpace, EControllerHand::Left, HandTrackingState);
    // Return if the struct data is invalid!
    if (!bGotHandTrackingState || !HandTrackingState.bValid)
    {
        return;
    }
    // Return if the device is not being tracked!
    if (HandTrackingState.TrackingStatus == ETrackingStatus::NotTracked)
    {
        return;
    }
    // Ensure that HandTrackingState.HandKeyLocations has the location data
    // for 26 joints!
    if (!ensureAlwaysMsgf(HandTrackingState.HandKeyLocations.Num()
                          == EHandKeypointCount,
                          TEXT("Invalid HandKeyLocations count!")))
    {
        return;
    }
    // Ensure that HandTrackingState.HandKeyRotations has the rotation data
    // for 26 joints!
    if (!ensureAlwaysMsgf(HandTrackingState.HandKeyRotations.Num()
                          == EHandKeypointCount,
                          TEXT("Invalid HandKeyRotations count!")))
    {
        return;
    }
    static constexpr int32 PalmIndex = static_cast<int32>(EHandKeypoint::Palm);
    const FVector& PalmLocation{
        HandTrackingState.HandKeyLocations[PalmIndex]
    };
    const FRotator& PalmRotation{
        HandTrackingState.HandKeyRotations[PalmIndex].Rotator()
    };
 ```
 The equivalent Blueprint code for the above looks something like this:
 ![Get a joint location and rotation from FXRHandTrackingState in Blueprint](consuming-fxrhandtrackingstate-blueprint-get-joint-location-rotation.png "Get a joint location and rotation from FXRHandTrackingState in Blueprint")
 OK, now that we've got a glimpse of how the virtual hand's joint data could be processed we are going to draw and animate a virtual hand in both [Blueprint](blueprint.md) and [C++](cpp.md) in the upcoming sections.

 Before continuing this section, please ensure you've studied the [Consuming FXRHandTrackingState](./) section, first.
 ## Drawing and Animating Virtual Hands
 1. Create a new Virtual Reality project based [the Unreal VR Template](https://dev.epicgames.com/documentation/en-us/unreal-engine/vr-template-in-unreal-engine).
 2. Make sure the [SenseGlove UnrealEngine plugin is installed and enabled](/getting-started/installation.md) inside your new project.
 ![Enabling the SenseGlove Unreal Engine Plugin](enabling-senseglove-unrealp-engine-plugin.png "Enabling the SenseGlove Unreal Engine Plugin")
 3. You could use either hand-tracking or a SenseGlove device as the input data, or both of the inside the same project. Whether you would like to use hand-tracking or a SenseGlove device, please make sure the required steps are taken for each of those first.
 4. You could add the required Blueprint code for drawing virtual hands to either your Level Buleprint or the VRPawn Blueprint Class located at `/Content/VRTemplate/Blueprints/VRPawn`. In this guide we are going to add the code to our VRPawn.
 5. Add a new function named `Draw Hand` with an input parameter of type `EController Hand` named `Hand`.
 ![Adding the Blueprint Draw Hand function](consuming-fxrhandtrackingstate-blueprint-add-draw-hand-function.png "Adding the Blueprint Draw Hand function")
 6. Inside this function's event graph add a `Get Hand Tracking State` node from `SenseGlove > Tracking > XR Tracker > Get Hand Tracking State`.
 ![Adding the Get Hand Tracking State node](consuming-fxrhandtrackingstate-blueprint-add-get-hand-tracking-state-node.png "Adding the Get Hand Tracking State node")
 7. Then connect the functions `Hand` input parameter to the `Get Hand Tracking State`'s `Hand` input and right-click on the `OutHandTrackingState` parameter and use the `Break XRHandTrackingState` node to break the struct to it's fields.
 ![Breaking the XR Hand Tracking State Data node](consuming-fxrhandtrackingstate-blueprint-break-xr-hand-tracking-state.png "Breaking the XR Hand Tracking State node")
 8. After this, we need to perform data validation by checking the return status of the `Get Hand Tracking State` function and `FXRHandTrackingState`'s `Valid` field. Then, we check if the hand-tracking device is being tracked and indeed coming from a hand-tracking source. And, finally, we check whether we have the positions and rotations for exactly `26` joints or not.
 ![FXRHandTrackingState validation](consuming-fxrhandtrackingstate-blueprint-validation.png "FXRHandTrackingState validation")
 9. OK, now it's time to draw the joints! If we check out the SenseGlove Debug module's draw option, we notice there are various ways to draw the debug virtual hand. Drawing a cube or a gizmo per joint, or draw the whole hand all at once by passing the retrieved `FXRHandTrackingState` to the `DebugVirtualHand::Draw` function! But, since the point of this tutorial is to learn how to consume the `FXRHandTrackingState` we ignore the last option. Between the debug cubes or gizmos, we are going to choose the gizmos since they better represent the rotations than the cubes.
 ![Some options for drawing a debug virtual hand](consuming-fxrhandtrackingstate-blueprint-debug-virtual-hand-draw-options.png "Some options for drawing a debug virtual hand")
 10. In the last step inside the `Draw Hand` function, in order to draw a virtual hand with `26` joints, we have to first iterate through either of the `Hand Key Positions` or `Hand Key Rotations` arrays from the  `FXRHandTrackingState` struct. Since we made sure both arrays have `26` elements before we reached this step, it's safe to just iterate over one and use the `Array Index` inside a `For Each Loop` or a `For Loop` to access the position and rotation of every joint. Then we use each array `Get (a ref)` method to access the position and rotation data inside the loop and call the `Draw` function from `SenseGlove > Debug > Gizmo` per every joint. Please note that there are two `Draw` functions and the only difference between the two is that one accepts an `FQuat` and the other a `FRotator` for its `Rotation` input parameter. In this case, we use the `FQuat` variant to avoid an extra conversion to `FRotator`. Also, please adjust the `Thickness` option for the `Settings` parameter from `1.0` to `0.2`, as the default value might be too thick for drawing a joint gizmo.
 ![Drawing a debug gizmo per each hand's joint](consuming-fxrhandtrackingstate-blueprint-draw-debug-gizmo-per-joint.png "Drawing a debug gizmo per each hand's joint")
 11. Well, now the full implementation for the `Draw Hand` function insde the `VRPawn` should look something like this:
 ![VRPawn Draw Hand function final implementation](consuming-fxrhandtrackingstate-blueprint-draw-hand-function-implementation.png "VRPawn Draw Hand function final implementation")
 12. Finally, go back to `VRPawn`'s event graph and the following code to the `Tick` event. Basically what we do here is call our newly implemented `Draw Hand` twice, once for each hand.
 ![Attempt to draw the left and right virtual hands every frame from the VR Pawn Tick event](consuming-fxrhandtrackingstate-blueprint-vrpawn-draw-virtual-hands-every-frame.png "Attempt to draw the left and right virtual hands every frame from the VR Pawn Tick event")
 13. Now, go back to the `VRTemplateMap` and use the VR Preview button to run the game. If everything's done correctly, you should be able to see the virtual hands inside your VR simulation.

 ## Drawing and Animating Virtual Hands
 1. Create a new Virtual Reality project based [the Unreal VR Template](https://dev.epicgames.com/documentation/en-us/unreal-engine/vr-template-in-unreal-engine).
 2. Make sure the [SenseGlove UnrealEngine plugin is installed and enabled](/getting-started/installation.md) inside your new project.
 ![Enabling the SenseGlove Unreal Engine Plugin](enabling-senseglove-unrealp-engine-plugin.png "Enabling the SenseGlove Unreal Engine Plugin")
 3. You could use either hand-tracking or a SenseGlove device as the input data, or both of the inside the same project. Whether you would like to use hand-tracking or a SenseGlove device, please make sure the required steps are taken for each of those first.
 4. From the `Tools` menu choose `New C++ class...`.
 ![Creating a new C++ class](consuming-fxrhandtrackingstate-cpp-new-class.png "Creating a new C++ class")
 5. Choose the Unreal Engine's `APawn` class as the parent class for the new C++ pawn class.
 ![Choosing APawn as the parent class](consuming-fxrhandtrackingstate-cpp-add-class-choose-name.png "Choosing APawn as the parent class")
 6. Name the new pawn class `DebugPawn`.
 ![Naming the new C++ class DebugPawn](consuming-fxrhandtrackingstate-cpp-add-class-choose-parent.png "Naming the new C++ class DebugPawn")
 7. Since we have created a new C++ class, this converts the current Blueprint VRTemplateMap project to a C++ one. That's why the Unreal Editor will give us a few prompts regarding opening the project in the default IDE and rebuilding the code. It might be simpler to just close the editor, then rebuild the source code inside your favorite IDE, and then start the editor with the converted project again.
 8. Find and open the VRPawn Blueprint Class located at `/Content/VRTemplate/Blueprints/VRPawn` inside the Blueprint Editor and from the `File` menu choose the `Reparent Blueprint` class.
 ![Reparenting the VRPawn Blueprint class](consuming-fxrhandtrackingstate-cpp-reparent.png "Reparenting the VRPawn Blueprint class")
 9. In the new `Reparent blueprint` window choose `DebugPawn` as the new parent.
 ![Reparenting the VRPawn Blueprint class to ADebugPawn](consuming-fxrhandtrackingstate-cpp-reparent-debug-pawn.png "Reparenting the VRPawn Blueprint class to ADebugPawn")
 10. By looking at the `Parent Class` label located under the Blueprint Editor window control buttons verify that the `ADebugPawn` class has been set as the new parent.
 ![Veifying whether the VRPawn Blueprint class set to ADebugPawn or not](consuming-fxrhandtrackingstate-cpp-verify-parent-class.png "Veifying whether the VRPawn Blueprint class set to ADebugPawn or not")
 11. Locate the project's main Build file, in our case `VirtualHandCpp/Source/VirtualHandCpp/VirtualHandCpp.Build.cs` and add the `InputDevice`, `OpenXRHMD`, `SenseGloveBuildHacks`, `SenseGloveDebug`, `SenseGloveSettings`, and `SenseGloveTracking` modules as either a private or public dependency.
 ```csharp
 // Fill out your copyright notice in the Description page of Project Settings.
 using UnrealBuildTool;
 public class VirtualHandCpp : ModuleRules
 {
    public VirtualHandCpp(ReadOnlyTargetRules Target) : base(Target)
    {
        PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });
        PrivateDependencyModuleNames.AddRange(new string[]
        {
            "InputDevice",
            "OpenXRHMD",
            "SenseGloveBuildHacks",
            "SenseGloveDebug",
            "SenseGloveSettings",
            "SenseGloveTracking"
        });
        // Uncomment if you are using Slate UI
        // PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
        // Uncomment if you are using online features
        // PrivateDependencyModuleNames.Add("OnlineSubsystem");
        // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
    }
 }
 ```
 12. Locate the C++ header and source file for the `ADebugPawn` inside the project in your C++ IDE. In our case they are located at `VirtualHandCpp/Source/VirtualHandCpp/DebugPawn.h` and `VirtualHandCpp/Source/VirtualHandCpp/DebugPawn.cpp`.
 13. Modify the `DebugPawn.h` header file to look like this:
 ```cpp
 // Fill out your copyright notice in the Description page of Project Settings.
 #pragma once
 #include "CoreMinimal.h"
 #include "GameFramework/Pawn.h"
 #include "SGSettings/SGDebugGizmoSettings.h"

    virtual void SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) override;
 private:
    // The method responsible for drawing a virtual hand.
    void DrawHand(EControllerHand Hand) const;
 };
 ```
 14. Modify the `DebugPawn.cpp` implementation file to look like this:
 ```cpp
 // Fill out your copyright notice in the Description page of Project Settings.
 #include "DebugPawn.h"
 #include "SGDebug/SGDebugGizmo.h"
 #include "SGTracking/SGXRTracker.h"

        FColor{255, 0, 0, 255},
        FColor{0, 255, 0, 255},

    {
        return;
    }
    // Return if the device is not being tracked!

    {
        return;
    }
    // Iterate over the hand joint locations and rotations!
    for (int32 JointIndex = 0; JointIndex < EHandKeypointCount; ++JointIndex)
    {
        const FVector& JointLocation{
            HandTrackingState.HandKeyLocations[JointIndex]
        };
        const FQuat& JointRotation{
            HandTrackingState.HandKeyRotations[JointIndex]
        };
        // Draw a single joint's gizmo!
        // Please note that we could alternatively:
        // Use FSGDebugCube::Draw() to draw a cube.
        // Or use the FSGDebugVirtualHand::Draw() method and pass the
        // HandTrackingState directly to draw the virtual hand
        // all at once without iterating the joints. But, that's not
        // goal of this tutorial.
        FSGDebugGizmo::Draw(World, JointLocation, JointRotation, HandDrawingSettings);
    }
 }
 ```
 15. Now, rebuild the source code and go back to the `VRTemplateMap`, then use the VR Preview button to run the game. If everything's done correctly, you should be able to see the virtual hands inside your VR simulation.

Boolean flags `bValid` and `bIsGrasped` provide quick checks on the state of the controller data. Identifiers `DeviceName` and `ApplicationInstanceID` ensure the correct association of data. Positional and rotational data `GripPosition`, `GripRotation`, `AimPosition`, and `AimRotation` offer precise tracking of the controller's movement. Arrays `HandKeyPositions`, `HandKeyRotations`, and `HandKeyRadii` allow detailed hand tracking, which is critical for immersive VR experiences. Lastly, the tracking status `TrackingStatus` informs the system of the reliability of the data being processed and whether the motion controller is actively being tracked or it's inactive at the moment.

 ## [2.2.2] - 2024-11-08
 This patch release addresses a few issues with both glove and hand-tracking.
 # Fixed
 - Fixed a chain of critical bugs that gets triggered due to `GloveConnectivityCheckInterval` getting passed as seconds to the engine rather than milliseconds. Thus, the default or any large value for `GloveConnectivityCheckInterval` causes noticeable long delays between glove-connectivity-check intervals and consequently renders the hand-tracking state invalid in certain situations when the `bFallbackToHandTrackingIfNoGloveDetected` option is false.
 ## [2.2.1] - 2024-10-23
 This patch release focuses exclusively on updates to the documentation.
 ### Documentation
 - Updated all URLs, screenshots, and tutorials to reflect the transition from the Unreal Engine Marketplace to Fab, Epic’s new unified content marketplace.
 - Revised documentation now points to the new home of the SenseGlove Unreal Engine Plugin on Fab, ensuring users have access to the latest resources and information.
 ## [2.2.0] - 2024-10-22
 This is a minor release with some breaking API and ABI changes, focusing mainly on migrating away from the deprecated `FXRMotionControllerData` in favor of `FXRMotionControllerState` and `FXRHandTrackingState` on Unreal Engine `5.5+`.
 ### Added
 - Completed support for the upcoming Unreal Engine `5.5` release.
 - Added `USGVirtualHandComponent::GetMotionControllerState()` and the equivalent Blueprint function`UVirtualHandComponentKismetLibrary::GetMotionControllerState` on UE `5.5+`.
 - Added `USGVirtualHandComponent::GetHandTrackingState()` and the equivalent Blueprint function `UVirtualHandComponentKismetLibrary::GetHandTrackingState` on UE `5.5+`.
 - Added `USGWristTrackerComponent::GetMotionControllerState()` and the equivalent Blueprint function `UWristTrackerComponentKismetLibrary::GetMotionControllerState` on UE `5.5+`.
 - Added `USGWristTrackerComponent::GetHandTrackingState()` and the equivalent Blueprint function `UWristTrackerComponentKismetLibrary::GetHandTrackingState` on UE `5.5+`.
 - Added a variant of `FSGDebugVirtualHand::Draw()` and the equivalent Blueprint function `USGDebugVirtualHandKismetLibrary::Draw_FXRHandTrackingState()` which accept `FXRHandTrackingState` on UE `5.5+`.
 - Added the new member `bTracked` to the `FSGXRHandState` struct.
 - Added `FSGXRTracker::GetMotionControllerState()` and the equivalent Blueprint function `USGXRTrackerKismetLibrary::GetMotionControllerState()`.
 - Added `FSGXRTracker::GetHandTrackingState()` and the equivalent Blueprint function `USGXRTrackerKismetLibrary::GetHandTrackingState()`.
 ### Fixed
 - Additional minor fixes and improvements that may not be listed here.
 ### Changed
 - Replaced all internal usages of the `FXRMotionControllerData` struct with either `FXRMotionControllerState` or `FXRHandTrackingState` on UE `5.5+`.
 - Deprecated `USGVirtualHandComponent::GetMotionControllerData()` on UE `5.5+`.
 - Deprecated `USGWristTrackerComponent::GetMotionControllerData()` on UE `5.5+`.
 - Deprecated the variant of `FSGDebugVirtualHand::Draw()` which accepts `FXRMotionControllerData` as a parameter on UE `5.5+`.
 - Renamed `USGDebugVirtualHandKismetLibrary::Draw` to `USGDebugVirtualHandKismetLibrary::Draw_FXRMotionControllerData` for more clarification.
 - Renamed an `FSGXRHandState` member from `bReceivedJointPoses` to `bHasReceivedJointPoses`.
 - Changed the `FSGXRTracker::GetAllKeypointStates()` signature on UE `5.5+` to match the `IHandTracker` interface API changes.
 - The animation system on UE `5.5+` has been revamped to utilize `FXRHandTrackingState` instead of `FXRMotionControllerData`.
 - The wrist tracking system on UE `5.5+` has been revamped to utilize `FXRHandTrackingState` instead of `FXRMotionControllerData`.
 - The hand interaction manipulation on UE `5.5+` has been revamped to utilize `FXRHandTrackingState`.
 - The virtual hand debugging system on UE `5.5+` has been revamped to utilize `FXRHandTrackingState`.
 ### Documentation
 - Added the documentation on consuming the `FXRHandTrackingState` struct in both Blueprint and C++.
 - Updated the documentation on consuming the `FXRMotionControllerData` struct.
 - Additional minor documentation fixes and improvements that may not be listed here.
 ## [2.1.4] - 2024-10-22
 This is a bugfix release that delivers some documentation fixes.
 ### Documentation
 - Updated the documentation on consuming the `FXRMotionControllerData` struct.
 - Additional minor documentation fixes and improvements that may not be listed here.
 ## [2.1.3] - 2024-10-11
 This bugfix release centers on adding initial support for the upcoming Unreal Engine `5.5`.
 ### Added
 - Added initial support for the upcoming Unreal Engine `5.5` release. Please note that, while the plugin is functional, a few adjustments are still required to address deprecation warnings. Specifically, the `FXRMotionControllerData` struct needs to be replaced with the newly introduced `FXRMotionControllerState` and `FXRHandTrackingState` structs, along with adjustments to adhere to the new hand-tracking API changes.
 - Added support for Epic Native Toolchain `v23`.
 ### Fixed
 - Fix a bug inside `USGVirtualHandComponent::PostEditChangeProperty()` where the get member name check happens against the wrong class and member names.
 - Additional minor fixes and improvements that may not be listed here.
 ### Changed
 - The SenseGlove libraries have been updated to `v2.105.0-02a2e508`.
 ## [2.1.2] - 2024-09-02
 This is a bugfix release that addresses a few non-critical issues and documentation fixes.
 ### Fixed
 - Fix a bug where the hands are always visible even when `bVisibleWhenHandDataUnavailable` is disabled.
 - Fix a bug where the `HandVisibilityChangedEvent` event is not triggered on the virtual hand component visibility changes.
 - Fix the wrong script name for `USGHMDTrackerKismetLibrary`.
 - Fix the wrong script name for `USGXRTrackerKismetLibrary `.
 - Fix `LogPython: Warning: 'SGHMDTrackerKismetLibrary' and 'SGXRTrackerKismetLibrary' have the same name (SenseGloveHeadMountDisplayKismetLibrary) when exposed to Python. Rename one of them using 'ScriptName' meta-data` when packaging the game.
 - Fix the non-existent default hand-mesh warnings polluting the logs when packaging the game.
 - Expanded the clickable area on the handbook index page revision buttons.
 - Minor documentation fixes.
 ## [2.1.1] - 2024-08-18
 This is a bugfix release with no actual plugin code changes, mostly addressing issues in the documentation and third-party dependencies caused by source control merge conflicts.
 ### Fixed
 - Fix the messed up changelog file caused by cherry-picking merge conflicts between the dev branch and the master branch.
 - Fix a bug that causes a handbook revision mismatch when deploying the handbook from the dev branch.
 - Fix a bug where `SG_GIT_IS_SHALLOW_CLONE` while building the handbook is always set to `yes` even if it's not a shadow clone because `SG_DOT_GIT_SHALLOW_FILE` evaluates to an empty string when the `.git/shallow` file does not exist.
 - Fix some documentation typos.
 ### Removed
 - Removed Android NDK r25 armv7 and x86 dependencies brought back by mistake while merging v2.1.0 from the dev branch to the master branch.
 ## [2.1.0] - 2024-08-16
 This is a minor release focusing mainly on bringing OpenXR-compatible hand tracking support (`XR_EXT_hand_tracking`) and Head-mounted Display automatic detection for adjusting wrist tracker offsets automatically at runtime.
@@ -127,6 +241,14 @@ This is a minor release focusing mainly on bringing OpenXR-compatible hand track
 - The `UXRDeviceVisualizationComponent` provided by Unreal Engine is used in the SGPawn class as ControllerVisualizerLeft and ControllerVisualizerRight for implementing the wrist tracking hardware visualization feature. However, it is not compatible with the new OpenXR system in certain scenarios. For instance, when the motion controllers serve as wrist tracking hardware since the SenseGlove plugin is now introduced to the engine as an `OpenXRHandTracking` system, it causes the UXRDeviceVisualizationComponent to visualize the wrist tracking hardware at coordinates (0.0f, 0.0f, 0.0f) instead of their actual location and rotation in the world. This happens because the component incorrectly registers them as inactive, possibly because it's assumed hand tracking and motion controllers cannot be in use at the same time. Currently, we use this feature solely for debugging, and we have an alternative in the form of wrist-tracking debug gizmos, which can be toggled on or off via the settings system. In future releases, we might remove this feature due to its incompatibility, unless we find a solution to make the `UXRDeviceVisualizationComponent` work with the new system. Alternatively, we may develop our own version of the `UXRDeviceVisualizationComponent`.
 - Although the SenseGlove OpenXR implementation is fully compatible with the `IOpenXRHMD` interface and the `FOpenXRHMD` `XRTrackingSystem`, it is not compatible with the `FOculusXRHMD` backend provided by the Meta XR plugin. The same issue likely applies to the VIVE OpenXR plugin. So, if these plugins are enabled in your project, the SenseGlove OpenXR will not function as intended, effectively breaking the plugin's functionality. It seems these plugins are necessary in order to make the fallback to the hand-tracking feature work on Android. While we may add support and compatibility with Meta XR and VIVE OpenXR plugins in the future, for the time being, if your project requires these plugins, we advise continuing with the `v2.0.x` release of the SenseGlove Unreal Engine plugin until this issue is addressed.
 ## [2.0.8] - 2024-07-15
 This is a bugfix release that contains a somewhat important bugfix backported from the next release of the plugin as documented below.
 ### Fixed
 - Fix a bug where the SGPawn right-hand grab colliders' default size is mistakenly set to the default value for the left-hand grab colliders at CDO initialization time.
 ## [2.0.7] - 2024-05-29
 This is a bugfix release with no actual plugin code changes, only fixing issues with binary assets incompatible with UE versions earlier than 5.4.
@@ -192,13 +314,6 @@ This is a patch release with no code changes.
 This is a bugfix release.
 ### Added
 - A fallback to HMD and wrist tracker hardware auto-detection mechanism has been added to be triggered in situations when automatic detection of the wrist tracker hardware is desired, e.g., either by not setting it explicitly, or setting it to the default None value.
 - Added the SGHeadMountDisplay utility class, exposed to both C++ and Blueprint, in order to easily gather information about the HMD at runtime.
 - Added the SGTypes header to the SenseGloveTypes module in order to define and share SenseGlove module types through this header across the plugin modules.
 - Added ESGHeadMountDisplayDevice enum with supported HMDs list.
 ### Fixed
 - Fix a bug inside both SGVirtualHandComponent and SGWristTrackerComponent where the connected glove's UObject instance gets destroyed and re-instantiated every frame. With this fix now the glove instance will be created or destroyed only when a glove connects to or disconnects from the system.

 - [ ] Get tracking input from sources other than a SenseGlove device.
 - [ ] Be able to assign behaviors to different objects (meshes) in the scene (e.g. Slider, Hinge, basic Grabables, etc).
- [ ] Make it so developers can define or extend their own behavior(s) to an object through Code / Blueprints (e.g. I want a car door that is like a slider, but follows a path rather than a straight line).

 - [ ] Make the hand(s) able to push around physics-driven objects (for as much as their behaviors allow) (in backlog).
 - [ ] Be able to grab objects with up to 2 hands (and move them around with both hands at the same time in a way that seems realistic).
 - [ ] Ensure that our virtual hands (and the objects they hold) do not phase through other physics objects (e.g. walls and tables).
