Mixed Reality is a blend of physical và digital worlds, unlocking the liên kết between human, computer, & environment interaction. This new reality is based on advancements in computer vision, graphical processing power, display công nghệ, and input systems. However, the term Mixed Reality was introduced in a 1994 paper by Paul Milgram và Fumio Kishino, "A Taxonomy of Mixed Reality Visual Displays." Their paper explored the concept of the virtuality continuum and the categorization of taxonomy applied to displays. Since then, the application of Mixed Reality has gone beyond displays to include:Environmental inputSpatial soundLocations và positioning in both real and virtual spaces

Environmental input and perception
Over the past several decades, exploration into the relationship between human và computer input has continued, leading khổng lồ the discipline known as human computer interaction or HCI. Human đầu vào happens through different means, including keyboards, mice, touch, ink, voice, and even Kinect skeletal tracking.
Advancements in sensors and processing are creating new areas of computer đầu vào from environments. The interaction between computers và environments is environmental understanding or perception, which is why the API names in Windows that reveal environmental information are called the perception APIs. Environmental input đầu vào captures things lượt thích a person"s position in the world (head tracking), surfaces, and boundaries (spatial mapping và scene understanding), ambient lighting, environmental sound, object recognition, & location.
The combination of all three - computer processing, human đầu vào, & environmental input - sets the stage for creating true Mixed Reality experiences. Movement through the physical world translates lớn movement in the digital world. Boundaries in the physical world influence application experiences, such as game play, in the digital world. Without environmental đầu vào, experiences can"t blover between physical and digital realities.
The Mixed Reality spectrum
Since Mixed Reality blends both physical & digital worlds, these two realities define the polar ends of a spectrum known as the virtuality continuum. We refer lớn the array of realities as the Mixed Reality spectrum. On the left-hvà side, we have sầu the physical reality that we as humans exist in. On the right-h& side, we have sầu the corresponding digital reality.
Augmented vs. virtual reality
Most di động phones on the market today have little to no environmental understanding capabilities. The experiences they offer can"t mix physical & digital realities. The experiences that overlay graphics on video streams of the physical world are augmented reality. The experiences that occlude your view lớn present a digital experience are virtual reality. The experiences enabled between augmented & virtual reality size Mixed Reality:Starting with the physical world, placing a digital object, such as a hologram, as if it was there.Starting with the physical world, a digital representation of another person--an avatar--shows the location where they were standing when leaving notes. In other words, experiences that represent asynchronous collaboration at different points in time.Starting with a digital world, physical boundaries from the physical world like walls and furniture appear digitally within the experience to help users avoid physical objects.
Most augmented reality & virtual reality offerings available today represent a small part of this spectrum & are considered subsets of the larger Mixed Reality spectrum. Windows 10 is built with the entire spectrum in mind, và allows blending digital representations of people, places, và things with the real world.
Devices & experiences
There are two main types of devices that deliver Windows Mixed Reality experiences:Holographic devices are characterized by the device"s ability lớn place digital nội dung in the real world as if it were there.Immersive devices are characterized by the device"s ability khổng lồ create a sense of "presence"--hiding the physical world, and replacing it with a digital experience.
|Example device|| obatambeienwasirherbal.com HoloLens || Samsung HMD Odyssey+ |
|Display|| See-through display. Allows user khổng lồ see the physical environment while wearing the headset.|

|Opaque display. Blocks out the physical environment while wearing the headphối.|
|Movement||Full six-degrees-of-freedom movement, both rotation và translation.||Full six-degrees-of-freedom movement, both rotation và translation.|
Whether a device is connected to or tethered to a separate PC (via USB cable or Wi-Fi) or self-contained (untethered) doesn"t reflect whether a device is holographic or immersive sầu. Features that improve mobility lead lớn better experiences, và both holographic và immersive devices could be tethered or untethered.
Technological advancement enables Mixed Reality experiences, but there aren"t any devices today that can run experiences across the entire spectrum. Windows 10 provides a common Mixed Reality platsize for both device manufacturers và developers. Devices today can tư vấn a specific range within the Mixed Reality spectrum, with new devices expanding that range. In the future, holographic devices will be immersive sầu, & immersive devices will be more holographic.
It"s best to think what type of experience an application or game developer wants to create. The experiences will typically target a specific point or part on the spectrum. Developers should consider the capabilities of devices they want khổng lồ target. Experiences that rely on the physical world will run best on HoloLens.Towards the left (near physical reality). Users remain present in their physical environment và are never made to lớn believe sầu they have left that environment.Towards the right (near digital reality).

Users experience a digital environment, & are unaware of what occurs in the physical environment around them.
