VR technology, namely virtual reality technology, is now well known. But you know what? As early as 30 years ago, Qian Xuesen, founder of China's aerospace industry and people's scientist, named VR "spiritual realm". The reporter recently saw some of Qian Xuesen's manuscripts from Qian Xuesen Library of Shanghai Jiaotong University, which showed that Qian Xuesen had named VR "spiritual realm" in 1990, and wrote a letter to explain that the translated name "has a strong Chinese flavor". This letter was written by Qian Xuesen to Wang Chengcheng, then leader of the intelligent computer expert group of the National 863 program, on November 27, 1990. From then on to 1998, Qian Xuesen wrote many letters to discuss VR technology with scientists such as Wang Cheng, Dai Ruwei and Qian Xuemin. On June 18, 1998, Qian Xuesen, 87, also wrote a short article "seeking truth from facts with" spiritual environment ", which wrote:" our traditional culture happens to have a word to express this situation: 'spiritual environment'; this is better than 'temporary environment', because this environment is virtual rather than real. " Wang Cheng, who communicated with Qian Xuesen, published a book on VR technology in the 1990s, entitled "theory, implementation and application of spirit realm (virtual reality) technology". Researchers from Qian Xuesen library said that since the 1980s, Qian Xuesen has been concerned about the field of artificial intelligence. Since the 1990s, he has been concerned about the research progress of VR technology based on the study of artificial intelligence. His views in the field of artificial intelligence can be summarized as "man-machine integration and people-oriented". Since then, new words, including VR, have been literal translated in order to better correspond between Chinese and foreign languages. What do you think of the word "spiritual realm"?
