How to Interact in VR - Oculus Interaction SDK - PART 1

https://www.youtube.com/watch?v=1FRqniErAfs&list=PLpEoiloH-4eMRR8wAfy22ecQeCT2tIuMD&index=1&ab_channel=ValemTutorials

基础设定

• 在project setting设置XR plug-in management - 勾选oculus（桌面&安卓）

• Download the Oculus Integration Package :https://assetstore.unity.com/packages/tools/integration/oculus-integration-82022

  • 包含内容：https://developer.oculus.com/documentation/unity/unity-utilities-overview/

• 删除原相机，添加OVRCameraRig prefab到场景

  • tracking origin type：floor level

• 添加控制器模型并指定

  

  

• 添加手部模型，prefab 组件属性中需指定对应左右手

  

  

• 添加 inputOVR - 包含控制器与手势的数据传递

  for V39 integration update, you first need to add the "interactaction OVR Camera Rig" script to the OVRCameraRig gameobject before adding the reference to InputOVR - that may be the reason some of you don't see your hands

  EDIT: TO UPGRADE TO V2 HAND TRACKING !!!

  Go to your OVR Camera Rig and inside the OVR manager script in the inspector, go down to the "quest features" menu. Under Hand Tracking Version, change it to "V2". Use this time to also make sure hand tracking support is enabled in the menu and also feel free to mess with hand tracking frequency. I'm not sure it even works for me yet since V1 and V2 feel the same but it may work for you

  • 将cameraRig拖拽指定，you need to add first a "Interaction OVR Camera Rig" component to the OVR Camera Rig and then you will be able to drag it.

    

  • 由于模型重叠，需要移除rig下的渲染组件；剩下两个组件inputOVR仍然需要

    

设置抓取互动

• 思路：设置 interactor & interactable

• 设置控制器抓取

  • 添加ControllerGrabInteractor 到inputOVR下的控制器

    

  • 组件中指定左右控制器（both

    

  • 在controllerInteractor的列表中指定子集的controllerGrabInteractor（both

    

• 设置手抓取

  • 添加prefab

    

  • 指定手部（both

    

• 设置互动物件

  • 互动物件需要有以下组件属性
    • collider
    • rigidbody
  • 若抓取时仍有重力影响，添加Physics Grabbable属性到物体上
    • 似乎也可以 rigid body 勾选 is kinematic - 结果看似乎会失活

• 设置手柄抓取

  • 为物件添加属性

    • transformable（script）（The "Transformable" component has been renamed to "Grabbable", it is the same as before except that now you need to drag the Grabbable component in all Interactable component as the "Grabbable" variable
    • grab interactable

  • 可手柄的关掉debug指示

    

• 设置手抓取

  • 为物件添加属性

    • hand grab interactable & 指定rigidbody和grabbable（似乎已缺省自动添加
      • snap type

  • If you still can't grab the object by hand, select the InputOVR from the scene then go to the input data provider update component and make sure to untick Enable Update & Enable Fixed update options. 如果手抓取不生效，关掉这两个选项

    

• 设置手柄 & 手抓取

  • 为物件添加属性
    • grab interactable
    • hand grab interactable

Two Hand manipulation and Restricted Grab - Oculus Interaction SDK - PART 2

restricted movement

• 限制物体抓取的移动范围（translation movement

  • 添加 one grab translate transformer

    • constraint are relative 设定坐标系基于物体pivot

  • 在grabbable中指定约束（拖拽上去

    

• 限制物体抓取的旋转范围

  • 添加 one grab rotate transformer
  • 指定到grabbable 同上
  • 创建一个用于当作pivot的空对象，作为旋转轴心

manipulate & scale object with two hand

• 添加 two grab free transformer

• 指定到grabbale的two grab transformer

• 添加 one grab free transformer 并指定以添加对单手的支持

• hand grab interactable 需要设置snap type为none

Hand Pose Grab - Oculus Interaction SDK - PART 3

https://www.youtube.com/watch?v=67hPv3C11Rk&list=PLpEoiloH-4eMRR8wAfy22ecQeCT2tIuMD&index=3&ab_channel=ValemTutorials

There is no more Hand Recordable and Hand Recorder, now to record a pose you can simply go at the top > Oculus > Interaction > Hand Pose Recorder and the rest is the same as shown in this video !

手势录制

• 为需要设置的物体，如马克杯添加属性

  • Add a Rigidbody, a Mesh Collider and a Grabbable component to it → make sure to check the box for Is Kinematic parameter of the Rigidbody component and also the check the box for Convex parameter of the Mesh Collider component.

    

• To record the hand pose:

  • On the taskbar, select Oculus→ Interaction→ Hand Pose Recorder. This will open up the hand pose recorder window.
  • Drag and drop the mugMesh GameObject into the Recordable parameter of the hand pose recorder. Basically, the object for which we are recording a hand pose should be set as a Recordable.
  • To be able to see the hand pose once it’s recorded we’ll have to add a ghost provider. To do that, click on the button next to the Ghost Provider parameter and select GhostProvider.
  • Now hit the play ▶️ button → add a grab interactor by clicking the button next to select the Hand Grab Interactor parameter and select the interactor of your choice (left hand or right hand).
  • Imitate grabbing the object with a hand pose of your choice and click on the Record Pose button.
  • We can capture multiple hand poses as well.
  • Before exiting the play mode, click on the Store Poses button.

  ---

  • 打开录制面板

  • 指定录制手(under play state

    

  • 添加存储位置

    

  • 打开 ghost provider

    

  • 打开Gizmos视图微调位置

  • 可以设置抓取状态手指关节位置、约束

  • 创建镜像手

    

设置合成手

修正抓取错位

• The Hand Synthetic prefab has been changed slightly, Now instead of dragging the Left hand or the right hand in the Synthetic Hand Modifier component, you need to drag them in the Synthetic Hand component of the Hand Modifier children. Then, the "Hand Grab Interactor Visual" component used at 6:47 is missing, you can add it back to the Hand Modifier gameobject and do the same setup as shown in the video

• 关闭原先的 hand visual

  

• 添加 left/right hand synthetic 到原先子集

• 设置 modify data

• 添加 Hand Grab Interactor Visual 在 handModifier 下，拉取参数

注意事项

• 带有手势指定的物品scale需要设置111，否则会带动子集手势缩放
• 添加surface让手的抓取可以在表面更改
