Understanding Augmented Reality

However, the truth is that nowadays, this technology completely blends in with our daily lives. Video games, medicine, education Virtual Reality is here to stay. But what is it exactly? Virtual Reality creates simulated environments the user becomes immersed in by using specific headsets or helmets. Virtual Reality VR is a computer-generated environment with scenes and objects that appear to be real, making the user feel they are immersed in their surroundings.

This environment is perceived through a device known as a Virtual Reality headset or helmet. VR allows us to immerse ourselves in video games as if we were one of the characters, learn how to perform heart surgery or improve the quality of sports training to maximise performance. Although this may seem extremely futuristic, its origins are not as recent as we might think. In fact, many people consider that one of the first Virtual Reality devices was called Sensorama, a machine with a built-in seat that played 3D movies, gave off odours and generated vibrations to make the experience as vivid as possible.

The invention dates back as far as the mids. Subsequent technological and software developments over the following years brought with them a progressive evolution both in devices and in interface design.

Despite being a technology that originated decades ago, many people are still unfamiliar with the concept of Virtual Reality. It is also quite common to confuse the term Virtual Reality with augmented reality. The main difference between the two is that VR builds the world in which we immerse ourselves through a specific headset. It is fully immersive and everything we see is part of an environment artificially constructed through images, sounds, etc.

On the other hand, in augmented reality AR , our own world becomes the framework within which objects, images or similar are placed. Everything we see is in a real environment and it may not be strictly necessary to wear a headset. However, there is also a combination of both realities called mixed reality.

This hybrid technology makes it possible, for example, to see virtual objects in the real world and build an experience in which the physical and the digital are practically indistinguishable. That's enough about the theory that is projecting us into the future. Which sectors is Virtual Reality actually being used in today? Medicine, culture, education and architecture are some of the areas that have already taken advantage of this technology.

From guided museum visits to the dissection of a muscle, VR allows us to cross boundaries that would otherwise be unimaginable. Now we can travel virtually to different places and immerse ourselves in certain environments while tasting the dishes from these locations. The Spanish National Research Council has succeeded in reducing the effects of Parkinson's in several patients by applying a treatment that uses VR.

In classrooms, the use of VR allows students to better retain knowledge and helps students with learning difficulties. Users can enter a scene in a video game or practice extreme sports without moving from their sofa.

RV helps architects to better envisage a space and present the project to their clients. Digital Twins are exact digital copies of physical objects that factory workers can practice on and test in a virtual world. Some museums and galleries offer virtual visits or immersive experiences to help understand the history and culture associated with each work. Virtual Reality is one of the technologies with the highest projected potential for growth.

In addition, both technologies will be key to companies' digital transformation plans and their spending in this area will exceed that of the consumer sector by It is, therefore expected that by over half of the larger European companies will have a VR and RA strategy.

Nowadays, the market is demanding applications that go beyond leisure, tourism or marketing and are more affordable for users. Virtual interfaces also need to be improved to avoid defects such as clipping, which makes certain solid objects appear as though they can be passed through.

Or to minimise the effects that VR produces in people, among them motion sickness, which consists of a dizziness induced by the mismatch between the movement of our body and what is being seen in the virtual world. The big technology companies are already working to develop headsets that do not need cables and that allow images to be seen in HD. They are developing Virtual Reality headsets in 8K and with much more powerful processors. There is even talk that in the next few years they could integrate Artificial Intelligence.

The latest 5G standard can also provide very interesting scenarios for the evolution of VR. This standard will allow more devices and large user communities to be connected. In addition, its almost imperceptible latency will make it possible for consumers to receive images in real time, almost as if they were seeing them with their own eyes. All this means that Virtual Reality is no longer science fiction. It is integrated into our present and, in the coming years, it will lead to advances that will shape the future.

Virtual reality VR is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment e. Other distinct types of VR-style technology include augmented reality and mixed reality , sometimes referred to as extended reality or XR. While both VRs are appropriate for training, Cyberspace is preferred for distance learning. This page mainly focuses on the immersive VR. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items.

Understanding Augmented Reality

Сьюзан вспомнила о единственном остающемся выходе - личном лифте Стратмора. Но она понимала, что надежды нет: электроника вряд ли уцелела после катастрофы. Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания. Я видел схему. Она знала, что это. Как и то, что шахта лифта защищена усиленным бетоном. Сквозь клубящийся дым Сьюзан кое-как добралась до дверцы лифта, но тут же увидела, что индикатор вызова не горит.

Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств. На фотографии она была изображена наклонившейся над постелью, в одних трусиках. Как выяснилось, кто-то из криптографов сосканировал фотографию из порножурнала и приставил к телу головы модели голову Сьюзан. Получилось очень даже правдоподобно. К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного. Два часа спустя был издан ставший знаковым приказ: СОТРУДНИК КАРЛ ОСТИН УВОЛЕН ЗА НЕДОСТОЙНЫЙ ПОСТУПОК С этого дня никто больше не доставлял ей неприятностей; всем стало ясно, что Сьюзан Флетчер - любимица коммандера Стратмора.

Virtual Reality: another world within sight

 Дэвид? - сказала Сьюзан.  - Ты, наверное, не понял. Эти группы из четырех знаков… - Уберите пробелы, - повторил. Сьюзан колебалась недолго, потом кивнула Соши. Соши быстро удалила пробелы, но никакой ясности это не внесло.

Все внимание Беккера сосредоточилось на открытой двери, и он забыл о жгучей боли в ногах. Задние колеса уже остались за спиной - огромные, доходящие ему до плеч скаты, вращающиеся все быстрее и быстрее. Беккер рванулся к двери, рука его опустилась мимо поручня, и он чуть не упал. Еще одно усилие. Где-то под брюхом автобуса клацнуло сцепление: сейчас водитель переключит рычаг скоростей.

 Мы не шпионим за простыми гражданами, и ты это отлично знаешь. ФБР имеет возможность прослушивать телефонные разговоры, но это вовсе не значит, что оно прослушивает. - Будь у них штат побольше, прослушивали .

Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи. В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни.
