Hololight Stream supports the usage of haptics through Unity Input Subsystem. For the details regarding the usage, please refer to the Unity Reference. Impulse and Buffer type haptics can be sent from the Input System. For additional implementations, check related classes from XR Interaction Toolkit (for versions 3.0+) and MRTK. Haptics are only supported on Quest 2, Quest Pro, Quest 3, Magic Leap 2 and Lenovo VRX.
Additional to the support for basic types of haptics, Stream also supports ".haptic" files created by Meta Haptics Studio. Files that are exported via the Studio can be imported to Unity and sent using the extension for InputDevice. For an example usage, please refer to the Meta Haptics sample in the samples package.
