    <p class="note" role="note"> For example, the Samsung HMD Odyssey’s controller is a design variant of the standard Windows Mixed Reality controller. Both controllers share the same input layout. As a result, the <code class="idl"><a data-link-type="idl" href="#dom-xrinputsource-profiles" id="ref-for-dom-xrinputsource-profiles③">profiles</a></code> for a Samsung HMD Odyssey controller could be: <code>["samsung-odyssey", "microsoft-mixed-reality", "generic-trigger-squeeze-touchpad-thumbstick"]</code>. The appearance of the controller is most precisely communicated by the first profile in the list, with the second profile describing an acceptable substitute, and the last profile a generic fallback that describes the device in the roughest sense. (It’s a controller with a trigger, squeeze button, touchpad and thumbstick.) <br><br> Similarly, the Valve Index controller is backwards compatible with the HTC Vive controller, but the Index controller has additional buttons and axes. As a result, the <code class="idl"><a data-link-type="idl" href="#dom-xrinputsource-profiles" id="ref-for-dom-xrinputsource-profiles④">profiles</a></code> for the Valve Index controller could be: <code>["valve-index", "htc-vive", "generic-trigger-squeeze-touchpad-thumbstick"]</code>. In this case the input layout described by the <code>"valve-index"</code> profile is a superset of the layout described by the <code>"htc-vive"</code> profile. Also, the <code>"valve-index"</code> profile indicates the precise appearance of the controller, while the <code>"htc-vive"</code> controller has a significantly different appearance. In this case the UA would have deemed that difference acceptable. And as in the first example, the last profile is a generic fallback. <br><br> (Exact strings are examples only.
