Assignment #4: Virtual Reality

What is VR?

Virtual Reality is a computer environment that represents, in a digital way, something that pretends to be real. It is generated by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.

Technology is the application of a set of knowledge and skills through electronics with the objective to achieve a solution that allows the human being from solving a given problem until reaching a need in a specific area.


Virtual reality has been a concept that has been developed throughout the years. It actually began in the nineteenth century when the idea was presented by Charles Wheatstone in 1838, when he began the development of the popular View-Master stereoscope (patented 1939), wich was used for “virtual tourism”.

Before then, panoramic paintings were the earliest attempt at virtual reality, as they were 360 degree murals intended to make viewer feel like they were present.

Later on, the concept of virtual reality was taken in 1929 when Edward Link created the “Link trainer” (patented 1931) probably the first example of a commercial flight simulator, which was entirely electromechanical. After that, the idea slowly started changing to a much simple concept, especially after the 1930s story by science fiction writer Stanley G. Weinbaum (Pygmalion’s Spectacles) was published, that presented virtual reality being seen through a pair of goggles.

In the mid 1950s cinematographer Morton Heilig then developed the Sensorama (patented 1962). Which was an arcade-style theatre cabinet that would stimulate all the senses, not just sight and sound.

Since then, then the concept has been taken by several people who have slowly built this, to be a revolutionary invention in the 21 century.

Virtual reality today:


Augmented Reality

This involves literally augmenting reality with virtual information. An augmented reality app will typically annotate live video with information in various formats. One novel example is a table top racing game in which you actually race on your table.

Virtual Worlds

Virtual worlds, such as Second Life, are played over the internet using a Mac or PC. Such applications open up a sandbox, allowing you to manipulate the world around you and can often feature their own currencies, with exchange rates to boot. There is even a booming virtual real estate market on Second Life.

This recent release by Microsoft probably offers one of the most in-depth virtual reality experiences around. The Kinect, at its core, is a motion sensor for the Xbox 360. Combining this with an expansive virtual world and goggles, you can become as immersed as you could possibly get.

Description: El uso de plataformas robóticas de movimiento en simuladores de vehículos y aplicaciones de Realidad Virtual es relativamente habitual. Sin embargo, el ajuste de los algoritmos que controlan su funcionamiento, denominados algoritmos de washout, no es sencillo y requiere de numerosas pruebas hasta obtener una apropiada fidelidad de movimiento. Es por ello que este trabajo presenta un método para la caracterización y simulación de manipuladores robóticos mediante filtros digitales de segundo orden, sencillo de implementar y ajustar a partir de una caracterización previa.
