The world is inevitably connected:As of January 2022, there were 4,950 internet users worldwide, making up about 62.5 percent of the world’s population.According to the indicators of the Digital 2022 report conducted by the creative agency We Are Social and Canadian platform Hootsuite; The computer is by far the second most used device for traveling over the network.


The real question that arises with an evolving digital society is: What do Latin American users have in common with American, Asian, European, African and Oceanic surfers? While seemingly insoluble, the answer lies ahead as millions of Internet users immerse themselves in the dynamic and ever-changing digital universe.

Functional for all and irrelevant for some, computer cursor is an essential tool often ignored by users. Despite this, it is used by millions of people around the world, regardless of continent, gender or computer brand.

Have you ever wondered what your web browsing experience would be like if you didn’t have a location indicator on a monitor or if you couldn’t interact with objects on the screen? These are some of the functions of the computer arrow, one of the most well-known indicators of web surfing and perhaps the most overlooked.

If you are one of those who spend hours at the computer, you must have noticed a small detail that seems insignificant at first glance: the cursor arrow is always in an italic state. Reason? Define the fine line between functionality and invisibility.

The fact that historically it was possible for a user to move around the desktop without using the keyboard is largely the achievement of Douglas Engelbart, who is considered the father and inventor of one of the objects that revolutionized the computer world: the computer mouse. The difference was that at the time -1960- it was called an XY Position Indicator for an Imaging System, not ‘mouse’; and its design was quite different from the modern peripherals in use today.

Electronics graduate from the University of California, Berkeley, World War II. A World War II veteran and doctor of engineering, Engelbart’s motto was simple: he wanted accessible technology. The Department of Defense, through Darpa (Defense Advanced Research Projects Agency), was the first institution to believe in its visionary ideal, and as a result gave its full support to have its own headquarters at the Stanford Defense Research Institute (SRI for acronym). English), according to the monthly magazine ‘Muy Interesante’.

The idea of ​​how to improve human-computer interaction was something that obsessed both Engelbart and the work group at the Augmentation Research Center. users by computers

From a ‘joystick’ (handle) to a lightweight pen, the inventions that Engelbart and his collaborators had in mind were as many as they were crazy, so that what seemed impossible was the ‘XY Position Indicator for Imaging System’, which according to the aforementioned magazine, “two wheelsets on the bottom and a carved alder block with a button at the top”.

This is how it was created The ‘mouse’, the first model of which is a kind of cube based on two wheels and allowing to move the cursor on the screen along one of the two axes. It was later patented by Douglas Engelbart on November 17, 1970.

It wasn’t enough for the legendary inventor to create one of the greatest computer gadgets of the time, but he wanted to showcase all the functionality he had developed at the ‘Mother of all demos’, a historic conference held in San Francisco, with his team over the past few years.

Over the course of 90 minutes, an astonishing audience of more than a thousand professionals witnessed for the first time many features of modern computer technology.: live video conferencing, document sharing, word processing, windows and a strange pointing device jokingly called a ‘mouse’. “The Computer History Museum is connected to others through elements of the screen, associative links or hypertexts.”

With the advent of the computer came the computer arrow known today as the ‘mouse’. The only difference is that the gauge faces straight up and is not tilted 45 degrees as it is today.

It was Xerox – the world’s largest supplier of toner copiers and accessories – that decided to oppose Engelbart’s initial design. Reason? The low resolution of the screens of the time threatened to make the cursor imperceptible, almost invisible; Why, the solution was to tilt the indicator slightly at a 45 degree angle to facilitate recognition.According to the ‘RPP’ radio chain.

As the ‘UXpañol’ portal explains: “the cursor was the same size as the characters and there was actually one more character. Well, it didn’t float in any direction like modern cursors, but instead scrolled vertically and horizontallylike when using the position arrows on the keyboard”.

Decades after its invention, users still use the italic cursor, even though high-resolution displays make it unnecessary.
