Unity provides built-in support for a number of Mixed Reality (MR) devices.
Device availability is on a per-platform basis, meaning that not every device is available for every platform. Multiple devices are available on certain platforms, and you can choose which MR devices your app will support from the available list.
En tiempo de ejecución, solamente un dispositivo se puede activar en un tiempo dado. Sin embargo, es posible cambiar ente dispositivos si usted ha escogido soportar varios dispositivos en su aplicación.
XRDevice.family is a string corresponding to the current XRSettings.loadedDeviceName. A family can have multiple models, which have different characteristics. The model can be accessed with XRDevice.model.
