虛擬實境（VR）的應用已擴展到多個領域，包括遊戲，教育，醫學和訓練。在這些應用中，使用者需要準確地感知周圍虛擬的環境。但是在虛擬環境中，使用者感受到的空間大小（尤其是距離）常比實際值小。人們使用從多種感覺（例如視覺，觸覺和聽覺）獲得的信息來感知距離。在本論文中，我們提出了在沉浸式虛擬環境中在視覺和聽覺刺激（有/無聽覺，無/短/長混響時間）的不同條件下以自我為中心的距離感知實驗。我們在每種情況下都觀察到距離的低估，也發現在視覺和聽覺刺激一致的條件下添加聲音會影響感知距離。然而，混響和混響時間都不會影響在連貫的視覺和聽覺條件下的距離估計。

Virtual Reality (VR) applications have extended to many fields, including gaming, education, medicine, and training. These applications require users to perceive the surrounding of the virtual environment accurately. However, the size of the perceived space, especially distance, is underestimated in the virtual environment. People perceive distances using information obtained from multiple senses, such as visual, tactile, and auditory.
In this study, we present a between-subject-design experiment of egocentric distance perception in different conditions of visual and auditory stimuli (with/without auditory, no/short/long reverberation) in immersive virtual environments. In general, the underestimation of distance was observed for each condition. The addition of audio in coherent visual+auditory conditions results in a more accurate perceived distance. We also found out that the quicker response of the participants to perceive distances, the more accurate results were produced.
