虛擬世界――virtual world雙語的

1、劉夢瓊 劉小曼 樊穎婷 葉海仙 徐凱霞,虛擬世界,Defined 定義,狹義的虛擬世界是一種“模擬的世界”。 廣義的虛擬世界是一種動態(tài)的網(wǎng)絡社會生活空間。 虛擬世界是一個不同于現(xiàn)實世界的由人工高科技技術如計算機技術、互聯(lián)網(wǎng)技術、虛擬現(xiàn)實技術等所創(chuàng)造的一個人工世界。 虛擬世界與網(wǎng)游本質區(qū)別就是：相互共鑄的，環(huán)境是大家來營造的，就跟現(xiàn)實社會是一樣，需要共同建造的。這不同于網(wǎng)游的單純殺怪、pk、靠升級變強，且只有單一的娛樂功能。,Narrow sense of the virtual world is an “analog world”.
