Sony interactive entertainment applied for the “holographic display” patent to USPTO (US patent and Trademark Office) in mid-2017. The patent describes a screen technology that can display holographic content, especially for video games, which was released on September 3, 2019.
Unlike most available 3D solutions, Sony holographic screen users do not need to use head display devices that reduce game comfort and freedom of movement.
In order to generate holograms, Sony uses a light-emitting device and a large number of micro mirrors, which can move or tilt rapidly, which is very beneficial to the reflection of light. The emitted light is modulated to project different images in the left eye and the right eye respectively, thus bringing 3D experience effect.
In addition to eye tracking, the patent also deals with face recognition to determine whether a single person or multiple people are using a holographic display, as well as the ability to recognize gestures, blink or nods. In addition, the camera and light sensor are used to calculate the distance from the player to the screen. Sensors can be placed anywhere, including the top edge of the screen, or all sensors can be placed below the screen. In this way, according to the patent specification, a complete borderless display can be created.
The image can be continuously adjusted with the help of micro mirror, so players can continue to move their heads when playing 3D games, or use the screen for 2D display. Sony has even found the opportunity for one user to view 3D images while presenting 2D images to a second user. This patent means more than that. Sony’s holographic display is also compatible with Playstation game consoles. In this way, you can bring 3D holographic experience to Playstation games, and you can play through the dualshock handle.
As early as 2018, red, an American camera company, launched the world’s first holographic projection smart phone, which was not only released by Sony, but also explored by Samsung. Recently, Samsung announced a patent for holographic projection. With this technology, smart phones and smart speakers can display weather, time, news and other information in the air through holographic projection, with a full sense of technology.
According to foreign media letsgo digital, Samsung obtained three-dimensional imaging electronic equipment patents through USPTO (US patent and Trademark Office) and WIPO (World Intellectual Property Office) on September 19, and obtained mobile phone design patents on September 20. It is reported that Samsung has developed this patented technology for three years.
According to letsgo digital, Samsung’s three-dimensional imaging scheme mainly uses three components: full screen display, half mirror and reflection element. The working principle is: put the smart phone into a special docking station, reflect the image on the full screen display screen displayed on the semi mirror through the reflection element, and finally project the image into the air to realize the air projection.
Samsung said in the patent introduction that there are two main factors affecting the quality of air projection image: air quality and secondary imaging quality of semi reflector. For the latter, Samsung explained in the patent that since the half mirror only projects part of the incident light into the air to generate images, the loss of the incident light leads to the loss of image quality. Therefore, Samsung plans to improve the image quality by adding a second reflection element.
The combination of mobile phone and hologram can always make people have a big Association. The hologram mobile phone makes people sound exciting. Holographic mobile phone is an innovative handheld terminal using CGH technology. The holographic technology here refers to the technology of recording and reproducing all the real three-dimensional image information of an object by using special technical means. Holographic mobile phones have been mentioned frequently since 2014, but due to technology, materials and many other factors, there is no real progress. As a representative of holography in China, WIMI Hologram Cloud (NASDAQ:WIMI) has been continuously upgrading its research and development and launching “holographic cloud application platform” to build a complete industrial ecological chain of holography.
Holographic projection technology, also known as virtual imaging technology, is a technology that records and reproduces the real three-dimensional image of an object using the principles of interference and diffraction. It’s really a high-tech show! Holographic technology can produce three-dimensional illusion in the air, and even make the illusion interact with people, very shocking! Full of sense of technology! Generally, we can only see it in science fiction movies.
Laser holography is a new photography technology which can record the amplitude (i.e. light intensity) and phase of light wave from the object at the same time, so as to reflect the depth of the object at the same time. It has a strong stereo sense. Ordinary photography records only the light intensity from the object, so there is no stereo sense. Based on the development of laser holography, non-destructive testing technology, laser photo microscopy, holographic storage technology, etc. have played an important role in industrial production and scientific research.
However, in real life, holographic technology is also constantly developing and improving. Next, we will talk about the use of holographic technology in mobile phones. Mobile phones, now very popular, everyone has a smart phone, and the emergence of “holographic mobile phones” will subvert the entire mobile phone industry, and even change the whole era.
In recent years, the AR holography industry has sprung up, and the industrial yield is booming: in 2014, the U.S. market alone benefited $90 million, and is expected to even surge to $5.2 billion by 2018. From Internet giants like Google and Facebook to hardware giants like HTC and Sony, they have invested heavily in AR holography. Statistics show that the total financing amount of domestic AR holography project in 2015 has reached 1 billion yuan, and the whole industrial chain in 2018 has reached trillions.
WIMI Hologram Cloud (NASDAQ:WIMI) has signed strategic alliance with related enterprises, and the scope of cooperation covers film and television, media, games, children’s education, animation, hardware, etc. The contents involved mainly include: establishing joint venture, AR IP, holographic IP and holographic entertainment content IP cooperation, as well as various commercial resource sharing, etc. WIMI Hologram Cloud (NASDAQ:WIMI) will form hundreds of patent protection according to 132 related patents it owns, and through strict patent protection means and technology confidentiality, to ensure that users can experience the latest and most advanced holographic AR high simulation digital product experience at the international level. At present, WIMI Hologram Cloud (NASDAQ:WIMI) focuses its business application scenes on five professional fields, such as home entertainment, optical theater, performance system, commercial publishing system and advertising display system.
Holography is also very popular in foreign countries, including Google’s cardboard, Facebook’s oculusrift, htcvive and Sony PSVR. Microsoft’s win10 hololens is currently the most popular augmented reality device. In addition, the holographic products of WIMI Hologram Cloud (NASDAQ:WIMI) are also expected. Through years of original research and development, the third generation holographic cloud light field has been created Technology products, user experience can be described as amazing. As the latest AR holography technology has more unknown technical secrets, it only costs a lot in the research and development of holographic cloud field holographic chip. Various original large-scale integrated circuits and software applications have completely subverted the thinking mode of ordinary people. Therefore, all technical details from the principle of optical field to the chip software are confidential.
The holographic image processing function of WIMI Hologram Cloud (NASDAQ:WIMI) is regularly optimized and improved, including two core technologies: holographic AI face recognition technology and holographic AI face change technology. Due to the development of video processing and recognition technology, WIMI Hologram Cloud (NASDAQ:WIMI) AR advertising and holographic imaging services based on image detection, recognition, template matching, image dynamic fusion and replacement are currently in a leading position in the industry.
Light field technology is more and more promising. It can capture real world objects and scenes, and present them with realistic digital results. In the past few years, companies such as lytro and WIMI Hologram Cloud (NASDAQ:WIMI) have been exploring the potential of this field, which is expected to provide a realistic AR holography experience. When using holoplayer, you don’t need to wear any head display or glasses to see the full 3D image. The projected image is emitted from the LCD screen and is suspended above the screen. The image presented has a resolution of 267 * 480 and displays 32 different views at the same time. In the interactive part, holoplayer uses Intel’s realsense depth camera to track the movement of the fingertips, and the display content will give feedback on the gestures and actions of the fingers.
3D space-based holographic AR does not need a 2D smartphone screen or a headset device, and the viewer can view the hologram superimposed in the real-time environment with the naked eye. The key component of 3D space holographic AR is the plane transparent film made of special materials, which is used to reflect and transmit light field to the audience and form holographic display experience. Popular examples include Japanese virtual singers in concert performances and guides to museums, exhibitions, theme parks and tourist attractions, such as fulfillment’s deep frame. A more complex product involving simultaneous positioning and mapping (“slam”) is navion by wayray, which is used as a head up display (“HUD”) in cars and holographic display on windscreens.
Holographic AR uses digital holography to record the digital hologram of an object, and then transmits the recorded information to a computer to analyze and form a 3D image, which is then displayed on a two-dimensional (2D) surface or three-dimensional (3D) space. Holographic AR combines the characteristics of hologram and augmented reality. Holograms are photographic records of light fields to show 3D projections of objects in the real world, just as physical objects are actually there.
Holographic display technology allows users to see three-dimensional virtual objects, which is not realized by digital technology, but by projection equipment to project images of different angles onto the top of the screen to form a three-dimensional image. From this point of view, this revolutionary solution is really expected to surpass the current naked eye holographic technology, so that mobile phone display technology to a higher level. Can the future commercial use of holographic projection become the next smart screen, give new vitality to smart phones, and even replace the current “no screen” technology with “aerial projection”, become a more matching content presentation mode with the current AI? This means that whether it is commercial or content adaptation, this technology will be faster than our previous imagination of the application progress of holographic projection.
