Speaking of media-free holographic technology, then you must know what it is?
Media-free holography, also known as air holography or free-space holography, is a holographic technology that is able to display stereoscopic images directly in the air, without the need for traditional physical media such as glass or special holographic films. This technique typically utilizes lasers, optics, and control systems to manipulate light waves to create visible, stereoscopic images in the air.
The core principle of dielectric-free holography technology is to use the coherent light waves generated by lasers to reconstruct the three-dimensional light field of objects at specific spatial points through interference and diffraction. This allows the observer to see the three-dimensional effect of the object from different angles without the physical medium.
At present, media-free holographic technology mainly does the combination of scene interaction, which refers to the ability to combine holographic images with the real environment and allow users to interact with these images. This technology is rapidly changing the face of many industries, and it is widely used in many fields:
1.Automotive: Media-free holographic technology is being used in the automotive field to provide an innovative human-computer interaction experience. For example, the ability to display screen content in the air in the car creates a completely new driving experience.
2.In the field of special vehicles: contactless elevator button terminals have been successfully implemented in many provinces and cities in China, and exported to overseas markets such as Malaysia, Singapore, and Dubai, which have effectively improved the health and safety standards of public facilities.
3.Smart education: Media-free holographic technology is also used in the field of education, for example, Xianghang Technology has cooperated with education companies such as New Oriental to develop innovative products such as media-free holographic smart education desks to provide a more three-dimensional and realistic teaching method.
4.Public display and cultural tourism: In the field of public display and cultural tourism, media-free holographic technology is used to create interactive exhibition experiences. For example, at the 2023 Hangzhou Asian Games, the use of media-free holographic technology can be seen in many places, providing visitors with a novel interactive experience.
5.Electronic products: such as media-free holographic Bluetooth speakers and desktop ornaments, etc., to provide users with a sci-fi interactive experience.
6.AI Digital Human and Metaverse Experience: At the 2023 Nanjing Software Expo, products based on media-free holographic technology, such as AI digital humans and metaverse experience cabins, also attracted widespread attention, demonstrating the potential of this technology in terms of virtual interaction and immersive experience.
If you look at the current market, you will find that Apple's latest Apple Vision Pro has a similar effect to medialess holographic technology. The Apple Vision Pro is Apple's first spatial computing device, which is equipped with 12 cameras and 5 sensors to handle functions such as spatial environment perception, gesture recognition, 3D modeling, and eye tracking, through a 3P Pancake folded light path, a micro OLED material main display, a spatial operating system VisionOS, "Video See Through" (VST) technology, and a unique dual-chip design. to achieve mixed reality (MR) effects. This technology is different from traditional VR or AR products, it directly realizes the perspective of the real world through optical means, seamlessly integrates digital content into the real world, and brings users a new 3D interactive experience.
However, as the number of people trying it out, some of the shortcomings and challenges of the Apple Vision Pro gradually came to light. According to feedback from professionals and user experience, in addition to the high cost, the uncanny valley effect caused by digital avatars, wearing comfort, battery life and external power supply, etc., the stability of perspective, gesture and eye tracking, device weight and field of view limitations are also issues that Apple urgently needs to optimize. Mediumless holographic technology, on the other hand, has potential complementarity with Apple Vision Pro in terms of augmented reality (AR) and virtual reality (VR). For example:
1.Enhanced visual experience: Media-free holographic technology can display high-definition 3D images in the air without a headset; The Apple Vision Pro, on the other hand, offers a highly immersive virtual reality experience. The combination of the two can create a richer and more realistic visual experience, such as incorporating media-free holographic technology into the virtual environment of Vision Pro to achieve a more realistic display of virtual objects.
2.Innovation in interaction methods: The gesture recognition and in-flight interaction functions of media-free holographic technology are combined with Vision Pro's eye tracking, gesture control and other technologies to create a more natural and intuitive way of user interaction. Users can use gestures to interact with holograms in a virtual environment, increasing the depth and breadth of the user experience.
In the future, with the vigorous development of media-free holographic technology and media-free interaction technology, there will be more and more application fields, according to the characteristics of the industry and application scenarios, it can have a far-reaching impact on the society more effectively. For example:
1. Reality (AR) augmentation: Media-free holographic technology can greatly enhance the reality experience, projecting virtual objects directly into the user's field of vision in three-dimensional form, and seamlessly integrating with the real environment. Users can interact with holograms through gestures, eye movements, voice, and other ways to achieve a more natural and intuitive way of interaction. It can be used for meetings, theater performances, commercial displays and advertisements, shopping mall displays, etc., to provide an immersive experience for the audience.
2.Virtual Reality (VR) Upgrades: In virtual reality environments, media-free holographic technology can be used to create more realistic virtual scenes that provide an immersive experience. Users can interact with holograms directly in the air without a head-mounted display, which will greatly improve the usability and user experience of VR.
3.Education and training: In the field of education, holographic technology can be used to create three-dimensional teaching models to help students better understand and remember complex biological structures, physical phenomena, etc.
4.Medical Imaging: The application prospects of media-free holography technology in the medical field include creating stereoscopic images of the patient's internal structures, viewing stereoscopic patient data, and helping doctors with diagnosis and surgical planning.
5.Telecommunication: Future holographic communication technology may allow people to appear in a three-dimensional holographic form in remote meetings, providing a more realistic and interactive communication experience.
6.Mixed Reality Experience: Mediumless holographic technology is combined with mixed reality (MR) technology to superimpose virtual images and information on the user's real environment to create a new mixed reality experience. This combination can be applied to a variety of fields such as gaming, education, design, etc., providing richer information and a deeper sense of engagement.
7.Home and office automation: In home and office environments, media-free holographic technology can be used to create intelligent assistants that allow users to control home devices or perform office tasks through a holographic interface for a more efficient and convenient lifestyle.
The development of media-free holographic technology and scene interaction will greatly promote the progress of human-computer interaction and provide users with a richer and more natural interactive experience. With the advancement of technology, the resolution, brightness, and color reproduction of media-free holographic technology will be further improved, and the scope of its practical application will continue to expand. At the same time, the development of this technology also needs to consider factors such as cost, safety, and energy efficiency to promote its popularization and commercialization in various fields.
