1 Introduction
In 2017, the Meta studio under Facebook launched a virtual reality head-mounted display device called "HoloLens". Unlike other virtual reality devices, HoloLens does not replace the user's real world with the digital world, but uses its Unique processing power transforms digital objects into images in virtual reality, capable of providing a feeling similar to the real world. Compared with the experience of the physical real world, the effect of this virtual reality is more three-dimensional and vivid, which makes many people very excited.
The scenes and experiences displayed by HoloLens have received widespread attention in the industry, but due to its limited performance and the pursuit of pure virtual reality effects, other leaders in the field of technological innovation have also abandoned the idea of HoloLens. However, with the development of VR/AR technology and the increasing demands of the consumer market, products like HoloLens are gradually being used by more companies and individuals.
So, what is the reason why HoloLens can attract many industry leaders to take a pessimistic view of it? In addition, are there other better VR/AR technologies for us to try? In order to answer these questions, this article will analyze from the following aspects:
- Entity VS Virtual
In the current Internet environment, Entity Virtual Mixed Reality (EVM) has become a new development direction, and the communication, collaboration and interaction between entities is becoming one of the most important needs in today's era. However, there is a huge gap between the physical world and the digital world - that is, the physical world cannot fully simulate the digital world, resulting in a loss of realism. Therefore, if physical virtual mixed reality wants to better integrate physical and digital, it must rely more on computer technology and more accurately restore the realism of the physical world. - Digital technology development
Traditionally, virtual reality technology is based on computer graphics rendering technology, served by a dedicated computer-generated environment (VRE). In recent years, the development of computer graphics technology has brought new virtual reality technologies, such as augmented reality (AR), virtual reality (VR), machine learning, etc. Among them, augmented reality (AR) technology generates digital images by
