SteamVR的配置文件:
{SteamVR安装目录}\steamapps\common\SteamVR\resources\settings\default.vrsettings 在配置文件中将头显设备设置成可选项: 可在不接入头显的情况下仅使用定位器功能
安装SteamVR Performance Test来评估电脑配置
评估您当前的系统是否达到运行 VR 的水平标准；若未达标准，判断性能限制来自于显卡、处理器或两者皆有。
https://store.steampowered.com/app/323910/SteamVR_Performance_Test/ Virtual Reality Supported可以控制SteamVR插件功能的开启或关闭，当我们导入了SteamVR Unity Plugin时，但又不想启动VR，可以去掉这个勾选项。 Stereo Rendering Mode(立体渲染模式)
Multi-Pass Stereo Rendering(多通道立体渲染)
Single-Pass Stereo Rendering(单通道立体渲染)
Single-Pass Instanced(单通道立体实例化)，进一步提升Single-Pass性能的技术。
多通道立体渲染性能要低于单通道立体渲染 关闭自动开启Virtual Reality Supported选项 三、跟踪设备姿态(位置、旋转)
这两个类都可实现对设备的姿态跟踪 SteamVR_TrackedObject 、 SteamVR_Behaviour_Pose ，将任一一个脚本挂到GameObject上，此GameObject的位置与旋转将与设备同步。

public enum SteamVR_Skeleton_FingerIndexEnum
	thumb,	//拇指
	index,	//食指
	middle,	//中指
	ring,	//无名指
	pinky,	//小指
    //获取输入Action: InteractUI
    //可通过SteamVR Input窗口查看和编辑所有Action
    public SteamVR_Action_Boolean spawn = SteamVR_Input.GetAction<SteamVR_Action_Boolean>("InteractUI");
    //SteamVR_Behaviour_Pose负责跟踪设备行为
    SteamVR_Behaviour_Pose trackedObj;
    private void Awake()
        trackedObj = GetComponent<SteamVR_Behaviour_Pose>();
    private void FixedUpdate()
        if (spawn.GetStateDown(trackedObj.inputSource))
        else if (spawn.GetStateUp(trackedObj.inputSource))
	示例：用扳机键与物体交互

    // 当手柄刚接触到物体时触发
    private void OnHandHoverBegin(Hand hand)
        Debug.Log("***** OnHandHoverBegin");
    // 当手柄持续停留在物体上时触发
    private void HandHoverUpdate(Hand hand)
        // 判断扳机键是否按下
        string actionSetName = "default"; //默认动作集
        string actionName = "GrabPinch";  //扳机键动作
        SteamVR_Action_Boolean GrabPinch = SteamVR_Input.GetAction<SteamVR_Action_Boolean>(actionSetName, actionName, true);

	示例：与UI元素交互
/// UI元素下面要放一个3D物体(如，Cube)，否则不会触发回调事件。

public class ButtonInteraction : UIElement

    protected override void HandHoverUpdate(Hand hand)
        base.HandHoverUpdate(hand);
        //Debug.Log("***** #HandHoverUpdate()");
	要使UGUI的Button与VR手柄交互，需要挂上BoxCllider、Interactable、继承自UIElement的脚本。 

VRInteractableButton.cs是继承UIElement的脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Valve.VR;
using Valve.VR.InteractionSystem;
/// <summary>
/// 挂在UI Button对象上
/// </summary>
public class VRInteractableButton : UIElement
    protected override void OnButtonClick()
        base.OnButtonClick();
    protected override void OnHandHoverBegin(Hand hand)
        base.OnHandHoverBegin(hand);
    protected override void OnHandHoverEnd(Hand hand)
        base.OnHandHoverEnd(hand);
    protected override void HandHoverUpdate(Hand hand)
        base.HandHoverUpdate(hand);
	Canvas设置

Render Mode设置为Screen Space-Camera

Render Camera设置成VRCamera，需要删除场景中原来的Main Camera

Plane Distance: Canvas距离VRCamera的距离(即，调整UI画面离眼睛的距离)
