元宇宙国际论坛:元宇宙发展现状分析

2022年7月4日,由南京信息工程大学和中国移动通信联合会元宇宙产业委员会主办,南京信息工程大学人工智能学院(未来技术学院)和杭州数字经济联合会元宇宙专业委员会承办,央链直播的“元宇宙与智慧教育国际论坛”在线上、线下双轨进行。论坛由元宇宙产业委常务副主任委员、南京信息工程大学人工智能学院院长潘志庚教授主持,论坛对元宇宙发展现状进行了分析。

论坛认为,20世纪90年代初,钱学森开始了解到“Virtual Reality”(虚拟现实技术),便想到将之应用于人机结合和人脑开发的层面上,并给其取名为“灵境”。他认为,灵境技术的产生和发展将扩展人脑的感知和人机结合的体验,使人与计算机的结合进入到深度融合的时代,并认为这一技术将引发震撼世界的变革,成为人类历史上的大事。

元宇宙到底是个什么宇宙?

元宇宙一词最早诞生于1992年的科幻小说《雪崩》,小说里面描绘出了一个庞大的虚拟世界。在这个虚拟世界里,人们可以用数字化身来控制提高自身的地位。并且,在人们所期望的元宇宙中,大家可以随时切换身份、自由穿梭在数字和物理世界中,并在这个虚拟世界中学习、工作、交友、购物和旅游等。而在现实中能做的在元宇宙中也可以完成。

清华大学新闻学院沈阳教授这样定义元宇宙:元宇宙是整合多种新技术而产生的新型虚实相融的互联网应用和社会形态。它是基于数字孪生技术和扩展现实技术在现实世界镜像中完成的沉浸式体验。元宇宙是一个不断发展和不断演变的概念,不同参与者以自己的方式不断丰富着它的含义。

元宇宙的构建需要哪些步骤

(1)数字孪生:现实世界完全镜像到虚拟世界中,在虚拟空间内建立包括人、物品和环境等要素在内的拟真动态孪生体。

(2)虚拟原生:虚拟世界里的人物能自动生成运转起来。不需要借助真实场景来参与。

(3)虚拟共生:现实世界信息与虚拟世界信息融合,且能相互共生。例如在虚拟世界拍照能够在现实世界中发朋友圈并打印。

(4)虚实联动:通过人工智能引擎支撑高仿机器人或虚拟人,并与现实世界中的自然人进行交互,同时实现场景和资产的虚实联动。

元宇宙的技术瓶颈

元宇宙所依赖的各项技术间呈现木桶效应,即元宇宙能够实现到什么样的程度取决于那块“短板”技术发展到什么阶段。就当前技术而言,各项技术只满足初期元宇宙的应用发展需要。虽然5G技术实现大范围覆盖,并且其延时问题得到较大改善,但仅仅可初步容纳目前元宇宙用户规模;UGC
