Viveデバイスの情報を取得する

Last updated at Posted at 2023-08-07

UnityでVive Tracker・Vive ControllerのIDや接続状態、電池残量など情報をしたかった

接続状態を取得する

OpenVR.System.GetTrackedDeviceActivityLevelの第一引数に「接続されているデバイスの番号」を代入すると取得できる

ViveDevice.cs
using Valve.VR;
public class ViveDevices : MonoBehaviour
{
    void Update()
    {
        if(OpenVR.System.GetTrackedDeviceActivityLevel(0) == EDeviceActivityLevel.k_EDeviceActivityLevel_Idle)
        {
            // Idle状態(SteamVRでデバイスが点滅している状態)
        }
        else
        {    
            // Active状態
        }
}

IDを取得する

OpenVR.System.GetStringTrackedDevicePropertyの第一引数に「接続されているデバイスの番号」
第二引数に「ETrackedDeviceProperty.Prop_SerialNumber_String」を代入すると取得できる

ViveDevice.cs
using Valve.VR;
public class ViveDevices : MonoBehaviour
{
    void Start()
    {
        string serialNumber = GetStringProperty(0, ETrackedDeviceProperty.Prop_SerialNumber_String);
    }
    
    string GetStringProperty(uint i, ETrackedDeviceProperty property)
    {
        ETrackedPropertyError error = ETrackedPropertyError.TrackedProp_Success;
        uint bufSize = OpenVR.System.GetStringTrackedDeviceProperty(i, property, null, 0, ref error);
        if (error != ETrackedPropertyError.TrackedProp_BufferTooSmall)
        {
            return null;
        }
        System.Text.StringBuilder buff = new System.Text.StringBuilder();
        buff.Length = (int)bufSize;
        OpenVR.System.GetStringTrackedDeviceProperty(i, property, buff, bufSize, ref error);
        if (error != ETrackedPropertyError.TrackedProp_Success)
        {
            return null;
        }

        return buff.ToString();
    }
}

電池残量を取得する

OpenVR.System.GetFloatTrackedDevicePropertyの第一引数に「接続されているデバイスの番号」
第二引数に「ETrackedDeviceProperty.Prop_DeviceBatteryPercentage_Float」を代入すると取得できる

ViveDevice.cs
using Valve.VR;
public class ViveDevices : MonoBehaviour
{
    void Start()
    {
        float trackerDevicesBattery = GetFloatProperty(0, ETrackedDeviceProperty.Prop_DeviceBatteryPercentage_Float);
    }
    
    float GetFloatProperty(uint i, ETrackedDeviceProperty property)
    {
        ETrackedPropertyError error = ETrackedPropertyError.TrackedProp_Success;
        return OpenVR.System.GetFloatTrackedDeviceProperty(i, property, ref error);
    }
}
