Overview

Virtual reality isComputerAn artificial environment that is a world created byCyberspaceTherealityAsPerceptionIt is a technology to make[2].SpacetimeIt is an environmental technology that exceeds(I.e. OfCognitionTo extend[3].

Computer graphicsIt is roughly divided into those that are presented to the user by using such as, and those that acquire the real world and record it offline or present it to the user online.The latter requires space sharing when the user is in a remote location,Telegression (Telexistence), Telepresence (Telepresence), Teleimmer John (Teleimmersion).The latter is5GIt is expected that it will be easier to realize in cooperation with.

When the computer adds and presents more information to a real-world object that the user can directly perceive.Augmented reality (Augmented reality) AndMixed reality (Mixed reality).

As a concept that expresses a state that has evolved indistinguishable from realitySimulated reality(Simulated reality) And Artificial Reality (Artificial reality), Which is a term used in science fiction and literature.

As for commercialization, the first VR boom in the early 1990s had a low number of polygons and resolution on the screen display due to technical limitations, and the accuracy of the sensor was low, so the movement of the user and the screen drawing were misaligned and it was easy to get drunk. , The price of VR equipment is also very expensive, and it did not spread and ended in failure.After that, commercialization progressed after the second VR boom in the early 1s.iPhoneAppeared2007 In the smartphone development competition from Japan, not only mobile CPUs but also sensors have been made smaller, more accurate and less expensive, which has led to the success of the second VR boom.

History

Concept stage in science fiction works

Stanley G. WeinboumGoggles-type VR system appears in the 1935 short story "Pygmalion's Spectacles" by[4]..This is a system that records virtual experiences of sight, smell, and touch in holography and projects them on goggles, pioneering the concept of virtual reality.

Although there was a time when it contributed, the space and maintenance costs for installing the equipment on a large scale may be required, and in recent years, with some exceptions, it has been declining.[13].

Modern virtual reality involves three elements: three-dimensional spatiality, real-time interaction, and self-projection (Presence / Interaction / Autonomy).

About the translation of "virtual reality"

Virtual reality was originallyシ ュ ル レ ア リ ス ムPoetAntonin ArtaudIs a coined word[22]It was an artistic term."Father of virtual reality" in the current sense[23][24]と 呼 ば れ るJaron LanierPopularized.

Originally, the English word "virtual" originally meant "strictly different but almost the same", and in computer-related contexts it was used to mean "it doesn't physically exist but looks like it". "Virtual reality" is one example (in other fields, but in electronic engineering terms).Virtual groundThe English text of the term is called "Virtual ground".It is not actually grounded, but it is the concept of being grounded in theory).

"Virtual reality" is used, for example, for applications such as robot operation in places where humans cannot go, and for making the virtual space created on a computer perceive as if it were real.Technology that superimposes and displays various digital information on a real sceneAugmented reality Different from (Augmented Reality).

On the other hand, the word "virtual" originally means "assuming" (Virtual enemyIn computer-related contexts, it is used as a translation of "virtual" in the above sense (eg).Virtual memory (Virtual memory, etc.) In that sense, "virtual reality" is sometimes translated as "virtual reality."

While the concept of virtual did not exist in China, there was no proper one-letter kanji and two-letter idiom to write it, while the currently used "virtual" and "imaginary" are misleading translations. Because of that, the University of Tokyo graduate school professor (at that time)Susumu TachiWas used as a translation of virtual reality at the 2005th Annual Meeting of the Japan Virtual Reality Society in 10.Vr kanji.pngI proposed the word "reality".Vr kanji.pngWas proposed for thisnative scriptso,Standing biasWrite Minoru (actual orthodox font) and read "Jitsu" or "Bacharu"[25][26][27].

VR problems

Health risk

Only one case of a child under the age of 10 being strabismus using a VR device has been reported in the past.[30]..In early childhood, eye muscles and eyesight are developing, and it is said that they are more likely to have adverse effects than adults.ちなみに立体細胞は6歳までに形成され、瞳孔間距離については10歳ごろまでに発達するため、VRデバイスの業界標準では対象年齢13歳以上など保守的な設定となりつつあるBy the way, three-dimensional cells are formed by the age of XNUMX and the interpupillary distance develops by the age of XNUMX, so the industry standard for VR devices is becoming a conservative setting such as the target age of XNUMX years or older.[31].

VR sickness

VR images cause VR sickness and cause headaches and nausea.PlayStation VRThen, as a precaution for health, by expressing light on the image (stimulation of light)痉挛,Consciousness disorderIf you feel any discomfort such as headache, dizziness, or nausea, stop using it immediately, and if it does not heal, consult a doctor. Is[32].. VR酔いはなぜ起こるのか完全な解明はされてはいないが、視覚系と前庭系の間でミスマッチが生じることではないかとされているThe reason why VR sickness occurs has not been completely elucidated, but it is suspected that there will be a mismatch between the visual system and the vestibular system.[33]..開発側でもこれらの問題が認識されており、不快感を軽減するため視点の移動速度やゲーム内の重力を調整するなどの対策が行われているThe development side is also aware of these problems, and measures such as adjusting the movement speed of the viewpoint and gravity in the game are being taken to reduce discomfort.[34].

Interest in VR

2016 was said to be the first year of VR, and it was expected that VR would become a boom, but when one year from the first year of VR opened the lidVR headsetSales are sluggish[35]..When asked why research firm Slive Analytics is not considering purchasing a VR headset, there were answers such as "price is high and content is low" and "it is likely to cause motion sickness".The most common answer was "simply not interested" at 53%.[36].

Chinese media reports that 9% of VR startups went bankrupt in China[37].
