Keyboard seems irreplaceable, still innovations are made to try to disrupt it

QWERTY keyboards have been around for over a century now. Created by the Remington company, the design of the keyboard dates back to the invention of the typewriter. Surprisingly and despite some minor improvements, keyboards have not changed from typewriters to our current smartphones. The layout of the letters has been adapted to other languages to give the French AZERTY for example but this is a rather minor evolution.

Being in the age of disruption of everything and anything, we are entitled to wonder why this invention has evolved little in a century.

The keyboard is an optimized response to…


A summary to remember which does what.

Augmented reality, virtual reality, mixed reality. These terms are heard more and more frequently and everything leads us to believe that the future of computing and businesses will be more and more focused on these technologies.
There is a tendency to confuse the three terms, which is normal when the promotional spots themselves make the amalgam. It is also the case of science fiction authors who do not always use the right terms to designate the right things.
To stop confusing terms, it’s just a matter of defining the boundaries of who does what. …

If you were to ask “what is ergonomics” no one would have too much trouble answering. The word “ergonomics” is part of the common language, it is a word that is used regularly.
“Ergonomic” is used pejoratively to complain about a device or situation that is not easy to use, and positively when it is a marketing sales argument. By deduction, “ergonomics” refers to what makes things ergonomic. …


Going mainstream in a few years

What’s Cloud computing

A PC is a mix of hardware (screen, graphic card, processor), an operating system (IoS, Window, Linux, Android), and software.

The software your computer can run is limited to the hardware it possesses. A low-quality graphic card can’t handle games with detailed graphics like GTA 5 or Cyber punk77.

With Cloud computing and Cloud gaming, that issue disappears because your computer is emulated and streamed. With this technology, all you need is to have a screen, mouse, keyboard, and Internet connexion.

Even if the technology has its cons, it’s still promising. To name a few :

  • It requires a good…


On ne devient pas l’homme le plus riche du monde uniquement en vendant des livres

Jeff Bezos est le plus riche ou du moins dans le trio de tête actuel des hommes les plus riches du monde. Quand vous avez plus de 200 milliards de dollars, ce genre de question triviale n’a pas d’importance.

Il est juste de se demander comment Amazon, un site de vente, l’a rendu si riche ? S’il n’y avait eu que cela, e-bay, Craiglist ou Leboncoin auraient fait des milliardaires de leurs créateurs.

La vérité est que la fortune de Jeff Bezos provient principalement d’un autre service qu’il possède : AWS.

Un fait amusant qui a fait…


You don’t become the richest man in the world only by selling books

Jeff Bezos is the richest or at least in the current top three of the richest man in the world. When you have more than 200 billion dollars, this kind of trivial question doesn’t matter.

It’s fair to wonder how Amazon, a selling site, made him so rich? If it was just that, e-bay or Craiglist would have made billionaires of their creators.

The truth is that Jeff Bezos’ fortune mostly comes from another service he owns: AWS.

A fun fact that went viral: to represent Jeff Bezos’ net worth in rice, you would need 58 lbs…

Les smartphones sont omniprésents dans nos vies. Ce petit appareil a changé à jamais non seulement nos vies, mais aussi la société dans son ensemble.

Presque tout le monde possède un smartphone, des jeunes aux personnes âgées, des riches aux sans-abri, dans tous les pays, même dans les villages sans électricité.

Cet appareil est un formidable carburant pour la créativité, et les gens aiment à imaginer des concepts de technologies qui remplaceront les smartphones actuels.

J’aimerais commencer l’année 2021 par une étude de cas sur ce sujet : quelle technologie pourrait remplacer les smartphones ?

Pour commencer…


Faisons un internet plus propre !

Un ordinateur posé dans un parc

Pollution plastique, empreinte carbone, disparition des animaux, tous ces problèmes ne sont pas nouveaux mais la société moderne semble enfin s’en soucier sérieusement.

Tous les domaines tentent de passer au vert, en capitalisant sur la façon dont les gens vont percevoir leur marque. En regardant des vidéos sur les nouvelles 2020 à Ux, je me suis demandé si ces tendances auront un impact négatif sur l’environnement ?.

Cette question s’est posée parce que l’une des tendances de 2020 pourrait être de mettre des vidéos plutôt que des photos sur les pages d’accueil des sites web (parce que…

Smartphones are omnipresent in our lives. This little device forever changed not only our lives but societies in its entirety.

Almost everybody has a smartphone, from youngsters to elders, rich people, and homeless ones, in every country even in villages without electricity.

Such an omnipresent device is a great fuel for creativity, and people like to come up with concepts of technologies that will replace current smartphones.

I’d like to start 2021 with a case study on this topic: what technology could replace smartphones.

To begin, let’s take a look at concepts that can be found easily…


When the diversity of backgrounds makes it harder for companies

When Don Norman first used the word UX design in the ’90s, only ten people could pretend to this title. Today over 238,000 active workers call themselves Ux designer in the US alone, and this number keep growing.

The market is far from saturated, but with more and more profiles of Ux designers available, it’s becoming harder for companies to find a set of skills suited for their needs.

For the same goal and the same job, two UX designers can have different backgrounds, sensibilities, and work’s methodology.

To counter that, companies must understand what is a Ux designer.
