虛拟現實的應用正變得越來越成熟。這種系統的要求和複雜性正在穩步增加。為了專注于應用中的互動可能性，現實的和詳細的環境往往被省略。建立一個準确和現實的虛拟環境不是外行人的任務，而是3D設計和模組化專家的任務。為了節約成本和避免雇傭專家，全景圖像經常被用來建立看起來很真實的虛拟環境。這些圖像可以由非專業人員捕捉和提供。全景圖像在許多情況下是手工制作的三維模型的替代物，因為它們提供了沉浸感，而且隻需按下一個按鈕就可以捕捉到一個場景的細節。這項工作研究了在某些情況下，是否應該用手工重新制作一個環境的細節，或者是否建議使用全景圖像來制作虛拟環境。為此，我們建立了一個互動式的虛拟環境，其中手工制作的3D環境與用全景圖像建立的環境幾乎沒有差別。加入了互動元素，并進行了使用者研究，以調查兩種環境對使用者的影響。所進行的研究表明，全景圖像可以成為3D模組化環境的有效替代品。
原文标題：Investigating the Sense of Presence Between Handcrafted and Panorama Based Virtual Environments
原文：
Virtual Reality applications are becoming increasingly mature. The requirements and complexity of such systems is steadily increasing. Realistic and detailed environments are often omitted in order to concentrate on the interaction possibilities within the application. Creating an accurate and realistic virtual environment is not a task for laypeople, but for experts in 3D design and modeling. To save costs and avoid hiring experts, panorama images are often used to create realistic looking virtual environments. These images can be captured and provided by non-experts. Panorama images are an alternative to handcrafted 3D models in many cases because they offer immersion and a scene can be captured in great detail with the touch of a button. This work investigates whether it is advisable to recreate an environment in detail by hand or whether it is recommended to use panorama images for virtual environments in certain scenarios. For this purpose, an interactive virtual environment was created in which a handmade 3D environment is almost indistinguishable from an environment created with panorama images. Interactive elements were added and a user study was conducted to investigate the effect of both environments to the user. The study conducted indicates that panorama images can be a useful substitute for 3D modeled environments.
