In 1838, scientist Charles Wheatstone described the concept of binocular vision, where the brain is able to combine two images to create a 3D image.[13] This led to the development of the first stereoscopes, devices that combined a pair of images and converted them into a three-dimensional image. Today these devices are used in virtual reality to create depth.

The origin of extended reality dates back to the late 1950s. Morton Heilig was the creator of the machine called Sensorama, which in his 1962 patent he defined as a form of sensory stimulation to achieve a more realistic experience.[14]​ In this sense, the appearance of augmented reality was born around 1990. Years later, in 1999, Hirokazu Kato") created ARToolKit"), a complete library of open source tools to create augmented reality applications.[15]​ This meant the definitive boost for developers and researchers in this field.

Cada vez surgen más dispositivos basados en formas de interacción natural e intuitiva y que están alcanzando éxito comercial y acercando las nuevas tecnologías a una mayor cantidad de usuarios. Algunos usos y herramientas relacionadas con la realidad extendida son:.

Video games

There are video games that make use of augmented reality such as Invizimals (2009), in which the player must use the device's camera to find creatures as if they were in the real world.[16] Other games such as Ingress (2012), Pokémon Go (2016),[17] or Monster Hunter Now (2023), use augmented reality by showing a map with the player's geolocation to play.

Children's applications

This would be the case of Quiver"), an application based on a children's book that allows children to color a template and then scan it with a device to watch their drawing come to life. A very similar application is Chromeville"). From an educational point of view, both augmented reality and virtual reality, included within the term extended reality, offer multiple advantages and that is that, through this type of applications, constructivist learning is facilitated and collaboration beyond the physical space is encouraged.[18]​.

Social networks

Some social networks such as Instagram, Facebook or Snapchat allow the use of augmented reality filters.[19] These are used to place different elements such as makeup, stickers, text or different accessories on the user's face that only exist through the screen.

Decoration and online furniture stores: The world of mixed reality has also strongly influenced the field of design and decoration. This technology allows you to take photographs or videos of a specific room with a smartphone camera and then insert a virtual piece of furniture into it, for example, a three-dimensional sofa. The biggest advantage of this is that the client can know without having to imagine how that sofa will look in their living room or whether or not they should change the furniture in their kitchen and this greatly facilitates the purchasing decision and the task of the designers and sellers. In this aspect, we can highlight the application of the Swedish multinational IKEA, which in 2017 launched Ikea Place"), a mixed reality application available on Google Play that helps us decorate our home by integrating 3-dimensional furniture directly from its catalog.[20]​ In the application, the furniture is aware of space and distance and is placed on the appropriate scale so that we can see how it would really look.

Robotics and artificial intelligence

In the field of robotics and artificial intelligence it is about the ability of machines to use algorithms, learn from data and use what they learn in making decisions in the same way that a human being would. Unlike these, machines do not need to rest and can work with large amounts of information in an instant. Increasingly, the use of artificial intelligence and robots have more impact in areas such as health, well-being, education, work and interpersonal relationships.[21]​.

space exploration

The use of extended reality (ER) systems has a long history in space exploration.[22]​ The first use of such by NASA is the LOLA simulator (Lunar Orbiter Laser Altimeter) with which the astronauts, crew members of the Apollo 11 and Apollo 12 missions, were successfully trained.[23]​ NASA built several moving flight simulators to allow astronauts to rehearse for the landing of the space shuttles. Thanks to laptops, astronauts could now bring portable versions of their flight simulators with which to practice landing while in low Earth orbit. Starting in the 1990s, an RE simulator began to be used to train simplified EVA rescue aid. On numerous occasions today, RE is being successfully applied on the International Space Station (ISS).

Education

Extended reality allows for interactive experiences that can increase student motivation and academic performance. Gamification,[28]​[29]​ or the creation of virtual museums and exhibitions[30]​[31]​ are examples of its application in this area.[32]​ This technology can facilitate the understanding of abstract concepts and foster critical, imaginative and collaborative skills.[33]​[34]​[35]​[36]​[37]​[38]​.

There are challenges regarding it, such as the lack of teacher training, or the digital divide among students. [39]​ Its integration into the educational system requires careful implementation, aligned with pedagogical principles.[40]​.
