The key obstacle is that costs are extremely high, while the technology is still immature, so that it cannot fully and effectively reproduce the environment desired. Thus many companies that would like to use this technology for training in sales or education are not willing to go forward.
主要癥結仍在於成本過高和技術不夠成熟，以致於無法把所欲模擬的環境做得惟妙惟肖，許多想利用此技術行銷或教育訓練的工商業界也因而卻步不前。
