vive focus plus About ViveInput.TriggerHapticPulse specification with vive focus plus

[h-shirakami]

I use the following SDK in unity for the development of vive focvus plus.
WaveSDK2.0.37
Viu 1.10.3

I was looking for a way to vibrate the controller.

ViveInput.TriggerHapticVibration
When I ran this API, nothing happened.

ViveInput.TriggerHapticPulse (HandRole role, ushort intensity = 500)
This API worked, but changing the intensity value doesn't change.

Is this a specification?
Or is it because the sdk version is low?

@h-shirakami I found out that VIU currently is using old haptic API.

This API's maximum vibration time is very short.

In latest WaveSDK(v3.1.4), there is new API for haptic.

I will provide patch for you by tomorrow to fix this part.

Thank you for your prompt reply.
Do I need to upgrade wavesdk?

@h-shirakami Please update your SDKs (VIU v1.10.6 from Asset Store and WaveSDK 3.1.4) to the latest version.

And add below code,

Under Assets\HTC.UnityPlugin\VRModule\Modules\WaveVRModule.cs,

line 771 after the override function TriggerViveControllerHaptic,

#if VIU_WAVEVR_3_1_0_OR_NEWER
        public override void TriggerHapticVibration(uint deviceIndex, float durationSeconds = 0.01f, float frequency = 85, float amplitude = 0.125f, float startSecondsFromNow = 0)
        {
            var deviceInput = WaveVR_Controller.Input(s_index2type[deviceIndex]);
            if (deviceInput != null)
            {
                if (0 <= amplitude || amplitude <= 0.2)
                {
                    Interop.WVR_TriggerVibration(deviceInput.DeviceType, WVR_InputId.WVR_InputId_Alias1_Touchpad, (uint)(durationSeconds * 1000000), (uint)frequency, WVR_Intensity.WVR_Intensity_Weak);
                }
                else if (0.2 < amplitude || amplitude <= 0.4)
                {
                    Interop.WVR_TriggerVibration(deviceInput.DeviceType, WVR_InputId.WVR_InputId_Alias1_Touchpad, (uint)(durationSeconds * 1000000), (uint)frequency, WVR_Intensity.WVR_Intensity_Light);
                }
                else if (0.4 < amplitude || amplitude <= 0.6)
                {
                    Interop.WVR_TriggerVibration(deviceInput.DeviceType, WVR_InputId.WVR_InputId_Alias1_Touchpad, (uint)(durationSeconds * 1000000), (uint)frequency, WVR_Intensity.WVR_Intensity_Normal);
                }
                else if (0.6 < amplitude || amplitude <= 0.8)
                {
                    Interop.WVR_TriggerVibration(deviceInput.DeviceType, WVR_InputId.WVR_InputId_Alias1_Touchpad, (uint)(durationSeconds * 1000000), (uint)frequency, WVR_Intensity.WVR_Intensity_Strong);
                }
                else if (0.8 < amplitude || amplitude <= 1)
                {
                    Interop.WVR_TriggerVibration(deviceInput.DeviceType, WVR_InputId.WVR_InputId_Alias1_Touchpad, (uint)(durationSeconds * 1000000), (uint)frequency, WVR_Intensity.WVR_Intensity_Severe);
                }
            }
        }
#endif

 

Now you can trigger vibrate by calling ViveInput.TriggerHapticVibration(role, hapticValue).

hapticValue is in seconds, if you set it to 1 sec, it will roughly be alittle bit more than 1 sec up to 2 sec.

I double check internally that Vive Focus Plus' controller does not have any intensity level, I hope this new API is enough for your development.

ViveInput.TriggerHapticVibration now works

Thank you so much.
