The medium-free holographic labor desk is equipped with the media-free holographic technology developed by XHOLO, presenting three-dimensional and three-dimensional learning image content in the air, and building a new educational interactive space. It supports clicking on the air screen to choose courses freely, which greatly stimulates the autonomy and desire to explore. It integrates functions such as electronically controlled lifting, NFC recognition technology, item access and educational content linkage mechanism, and has a rich built-in learning resource package, which comprehensively covers the multi-disciplinary and multi-field knowledge system, and supports the teaching evaluation system to accurately quantify students' learning results. Whether it is the centralized teaching mode of traditional classroom teaching, or the decentralized learning scenarios of online education and distance teaching, it can show applicability and functionality.
