The virtual reality is the creation of 3D interactive worlds by computer, with the intention of immerse the user in another reality. To this, normally, is used goggles that has an screen for each eye, creating the sensation of be in a 3D world around us everywhere. See here how has evolved this discipline.

The past day 23 was celebrated the twentieth edition of the Loebner prize in the University of California. This competition consist in test several chatbots to see if they are capable to surpass the Turing test. Enter into "Winner of the Loebner prize 2010"

Was the year 1996 when the professor Weizenbaum created ELIZA, the first chatbot application and the first that the human could use to talk about their problems, because was a psychotherapist. Later, in 1971, Colby, Weber and Hilf developed PARRY, another chatbot, but this time was a paranoid schizophrenic made to chat with ELIZA. So they hooked up at ARPANET (pre-Internet) and put them to chat together. Do you want to know what happened? Follow reading "When the machines talked to each other"

Although Japan is the country more advanced in robotics, they are not sending a lot of robots to work in the nuclear plant of Fukushima. We don't know if this is because they spend more money in the robots than in the humans or because only have thought in build robots that do domestic task. However, at least they have sent one robot. Don't stop reading the rest of "Robots to repair nuclear plants"

Microsoft wants that we can play with the Xbox 360 moving us in front of the screen. For that have spend hundreds of millions of dollars in develop a device to realize the recognition and the tracking, not only of a complete person but several ones, including also 3D information, its name is Kinect. In this post you will discover how works the hardware and the artificial intelligence algorithms that uses. Don't miss the rest of "Kinect: How works its 3D body tracking"

Today I woke up philosophical so I'm going to explain the famous Turing test.
The Turing test was proposed in a scientific paper called "Computing Machinery and Intelligence", wrote by Alan Turing in 1950. This is a test that must surpass a machine in order to show that it is intelligent. Read all about of "The Turing test and the Chinese room"

The RGB color model is a great invention which allows that with the mixture of different intensities of red, green and blue, any monitor or television can reproduce the colors of the reality. But ... how is it achieve? and why the colors of the model aren't others? The answer is in our eyes.
The retina is the part of the eye where we capture the light, and this is made thanks to a kind of modified neurons for detect photons: the rods and the cones.

In an epoch in that only were a few mechanic calculators, Alan Turing, was able to define the working, the limits and the possibilities of the computers. He not only was ahead to his epoch, but also to the actual and if had not been suicided, probably he would invented something that would convert the computers in something obsolete.

The previous post was about robots with body inspired by animals, so that in this I'm going to talk about robots with intelligence inspired in the nature. This are a lot of more interesting, because its programming, unlike to the robots of the prior post, is more related with the artificial intelligence than with the physics.

There are a lot of robots that simulate the behavior and imitate the form, structure and movements of some animals. The engineers copy them because they know that the evolution had have millions of years to get solutions that gives the maximum performance with the minimum energy expenditure, so reproduce the nature allow us resolve problems that in otherwise hardly we could resolve.

The past month died three great geniuses that had made that the computing be as it is today. I'm referring to John MacCarthy, Dennis Ritchie and Steve Jobs. Probably you only know who is the last, which is the only one that has had media coverage. However is the less important, because if the other two had not existed, Steve Jobs perhaps wouldn't have achieved anything. Follow reading "Great personalities of the computing deceased recently"
