&lt;h2 id="challenge">Challenge&lt;/h2>
&lt;p>The track evaluates whether a system can locate and segment the functional part of a 3D indoor scene that enables a language-described action. For example, given an instruction such as opening a refrigerator, the system must ground the request to the relevant interactive element, such as its handle, rather than only recognizing the refrigerator as an object.&lt;/p></description></item></channel></rss>
