People often confuse augmented reality (AR) with virtual reality (VR), which is very similar to it. Although AR and VR headset technology is changing the world around us. With technology, even incredible things can become a reality. However, if we go further and integrate the digital world with the real world, what kind of miracle will happen?
Augmented reality (AR) hopefully helps us do this. AR can change the way we visualize, share ideas, learn knowledge, and use imagination. With AR, you can also add visual overlays or 3D digital images on the basis of the real world, and use the information from the digital world to enhance the real world situational experience. Through the head-mounted display device (HMD), you can watch the augmented reality.
The advanced version provides stereoscopic 3D high-definition video and audio, but the concepts and use cases are still different. AR is open and cannot provide a completely immersive feeling. Users can see the real world around it through it. VR is closed and puts users in a virtual world.
AR is like Iron Man, and VR is Avatar. Tony Stark can analyze the surrounding environment through the information displayed on the helmet, and hear voice prompts at work, while the actor in the movie Avatar fully enters another world and lives a completely different life through the avatar. We expect some influential companies, such as Google or Apple, to drive the development of a complete AR platform. For example, Apple announced the launch of ARKit â„¢, which provides developers with a set of tools that can be used to build augmented reality into apps on iOS 11.
â–ª Some interesting use cases of AR include:
-Retail: German retailer Saturn â„¢ is trialling an augmented reality salesperson named Paula â„¢. If you walk into a retail store and wear Microsoft HoloLens â„¢, Paula â„¢ can guide you to select products and introduce you to the functional characteristics of the products. In addition, it can also help during the sales process.
-Education industry: AR teaches by simulating real life, replacing the highly complex teaching equipment required for complete demonstrations. With the help of AR applications and platforms, students can visualize 3D models in real time in real environments, which helps them better understand the concepts they want to learn.
-Manufacturing and maintenance industry: Aircraft maintenance is a very difficult job, because it takes years of training to understand tools, components and related instructions. Airbus â„¢ is using wearable technology to dramatically speed up labor-intensive aircraft maintenance processes while improving accuracy. When performing maintenance, employees can wear head-mounted displays and visualize the entire activity, which can shorten training time.
-Construction industry: With the help of AR applications, relevant teams can even visualize completed projects at the construction site before construction begins. Architects can enter the house, double-click to change the color or layout, and immediately see the change.
-Tourism: You can learn more about city landmarks or museums anytime, anywhere. With AR, visitors can view the latest relevant information according to their needs and preferences. For tourists traveling abroad, language exchange is a big problem. AR can translate different languages ​​by scanning the languages ​​displayed on signs, airports and other locations.
â–ª Some interesting use cases of AR include:
In terms of the commercial use of AR, the biggest limitation is the lack of suitable content, which needs to be created from scratch. Even the simplest form of AR headsets needs to recognize the environment, understand gestures, process information, and project digital content in real time. A high-resolution forward-looking camera suitable for use in HMD helps capture the environment in the field of view (FOV), and a series of sensors, including depth-sensing cameras, help identify the relative spatial position of various objects. The optical system in the AR headset is very complicated. After processing the information from the sensor and camera, the optical projection system will project the digital information into the user's FOV.
Some early designs of AR headsets (such as Google Glass) are designed to project digital information to help users make better decisions; some newer, more advanced AR headsets (such as Microsoft HoloLens) have more processing capabilities, Better optical and power management functions allow users to interact with these digital objects. All the features of these advanced headsets allow users to see and interact with virtual objects in 3D as if they exist in a real environment.
â–ª Storage options in AR headsets
AR headsets are usually unrestricted devices that can be operated without the need for hands. This also means that most of the calculations are done in the headset. Earlier versions of Google Glass used TI OMAP 4430SOC (system chip), 1GB (billion bytes) low-power DRAM, 16GB storage, 5MP (megapixel) camera and Android 4.4. However, the first-generation Microsoft HoloLens device uses Intel 32-bit architecture, GPU and custom holographic processor (HPU), equipped with 2GB mobile DRAM (LPDDR) and 64GB storage (eMMC). Given that the types of applications supported by these AR headsets include but are not limited to communicating with people miles away, in the short term, the architecture of these advanced AR headsets can be like a smartphone. Compared to the processors used in PCs and servers, the processors that drive computing in these headsets are more likely to be similar to the chipsets in high-end smartphones, with high performance and low power consumption. In addition, to store data locally on the headset, you need to use eMMC, SD card, or SSD storage. Various SLC / MLC NAND products, LPDDR2 / 3/4 products, eMMC or multi-chip package (MCP) products (the latter can encapsulate NAND and LPDDR together for effective integration and space saving) can meet this kind of Limited storage requirements for AR headsets.
â–ª Future development trend
Although AR and VR devices are still separate devices at present, it is foreseeable that these two tasks will be completed by one device in the future. As Micron Technology mentioned in this article, AR and VR both rely on reality continuity and varying degrees of digitization. As the resolution of monitors continues to increase, and high-quality and low-latency data rendering has become a necessary technology, people's computing needs for these headsets may exceed the demand for advanced smartphone functions. Such functions may need to be implemented by dedicated hardware and software that can process terminal applications more efficiently.
This is a very interesting era, the development of AR and the development of machine learning (ML) go hand in hand. ML This technology can give computers the ability to learn without explicit programming. In the field of ML, image recognition and speech analysis are the two most prominent technologies in today's research. This is also consistent with the function of AR headsets. With the continuous development of ML, AR headsets can be used as intelligent terminal devices for training these ML algorithms. Smarter and smarter algorithms, in turn, can provide the most relevant information for AR glasses, making the latter an indispensable device.
â–ª Summary
Augmented reality is an exciting new market that is evolving at an alarming rate. As the concept of the connected world is formed and developed into reality, humans can interact with the surrounding world with augmented reality glasses, and can also interact with each other. Now, this technology is still in its early stages, and it still needs to go through a long and exciting road of development. Micron Technology will continue to work hard to support augmented reality headsets and make them a product category under storage products, so that they can not only stand out from other products, but also ultimately enhance the customer experience.
