This paper describes the applications and challenges of virtual reality (VR) technology, with a focus on how to improve users' sense of experience in VR environments. In order to better understand users' sense of experience in VR environments, this paper uses a variety of methods for data analysis. The findings show that the older and longer the duration, the more immersive the user is and the higher the immersion with Oculus Rift. 30-36 year old males, 32-35 year old females, and 34-40 year olds experienced higher immersion, while 34-44 year olds had the lowest motion sickness but the best experience. Men with HTC Vive experience higher immersion, while women and others with Oculus Rift experience higher immersion. According to the study, the HTC Vive is best for users under the age of 30, the Playstation VR is best for users aged 30-50, and the Oculus Rift is best for users over 50. In terms of duration, the Oculus Rift provides the best experience for users under 10 minutes and over 40 minutes, while the HTC Vive is better in the 10-40 minute duration. Male users are most immersed at 23-31 minutes, female users are most immersed at 23-31 minutes, and other users are most immersed at 26-33 minutes. Motion sickness was lowest, but the best duration of the experience was 31 minutes.HTC Vive users felt higher immersion at 25-32 minutes, Playstation VR users at 21-28 minutes, and Oculus Rift users at 25-34 minutes. These conclusions provide an important reference basis for improving users' experience in the VR environment. At the same time, this paper puts forward targeted recommendations based on the conclusions drawn from the statistical analysis of the data, which can largely help users to improve the sense of VR experience and bring users an immersive virtual reality experience.
