The dimensions of the controller are roughly 6 x 3.5 x 2 inches. The Dual Shock has on the left side, the same directional pad found on most controllers. However, on the right, the action buttons are labelled with original symbol; this is also an innovation by Gotoh while conventional controllers normally used numbers and letters to label the buttons, as he states himself: "Other game companies at the time assigned alphabet letters or colors to the buttons. We wanted something simple to remember, which is why we went with icons or symbols, and I came up with the triangle-circle-X-square combination immediately afterward." In an interview reported by Games Radar, Gotoh explained how it came up with the symbols "I gave each symbol a meaning and a color. The triangle refers to viewpoint; I had it represent one's head or direction and made it green. Square refers to a piece of paper; I had it represent menus or documents and made it pink. The circle and X represent 'yes' or 'no' decision-making and I made them red and blue respectively."...

We just reviewed the evolution of the game controller in general. Now let’s dip in the very interesting story of the creation of the PlayStation Controller. The facts reported here mainly come from Kevin Gifford who wrote the "PlayStation 1 Design" article and from Reiji Asakura who wrote the book "Revolutionaries at Sony – The Making of the Sony PlayStation and the Visionaries Who Conquered the World of Video Games."...

This study is about a device which is probably the best joypad of all times: the Dual Shock. It has many variants and we can expect it to keep evolving in the coming years, however, we will focus here on the current version, the Dual Shock 3. In this article, we will go through the history of the game controller in general and then focus on the history of the Dual Shock itself, so that we understand in which context and how it was built. In a next part, we will then analyse the controller by studying its specifications and comparing it to its most direct competitor, the Xbox 360 controller. Basics There are many categories of game controllers, among which we will retain the most popular one, the gamepad, as that’s exactly what the Dual Shock is. Gamepads, also known as joypads, can have many action buttons combined with one or more omnidirectional control sticks or buttons. They are held using both hands with fingers (typically thumbs) used to provide input; as mentioned on Wikipedia, most modern game controllers are a variation of a standard gamepad. Common additions include shoulder buttons placed along the edges of the pad, joysticks, centrally placed buttons and internal motors that provide haptic feedback (as in, they typically vibrate). Some history In his article intituled “History of the game controller”, Catalin Ivan stated “Ever since the very beginning of video gaming, the controller has been the best (and usually the only) way of man-machine interaction.” That’s actually an interesting fact, and it would be good to follow the evolution from that “very beginning” to see how we reached the current gamepad technologies. There had actually been many, many gamepads released throughout the history, we are not going to study all of them, we are just going to review those who appear like important milestones that we observed from a study by John Honnibal and that we are summing up in the following table:...

Shopping is a time consuming process; the rhythm of our lives, jobs and other activities goes so fast that we hardly find time to shop properly. The current technologies provide us solutions to speed up the process by shopping online. But even online, shopping remains a task that involves some effort, thinking and time for every purchase. Sometimes you just don’t feel like doing it; or you got a lot of other things to do. Further, we are sometimes so busy that we may just forget to do it. Another thing is that it may be such a pain. Sure, it's fun to shop for new clothes and shoes. But it’s not fun to go get vegetables and meat every week. The solution What if you could just decide once what should be there in your fridge at all times and not worry about it again? You could just have what you want at all time without having to regularly spend the effort, time and thinking that food shopping require. And that's what the new Google Supply Search Engine (GOOSE) is all about....

Did you know that you have a digital identity? Well, yes, you do. You don't have to request it from any legal authority (for now, at least). It already exists and it can either elevate you or harm you. How? Because from the day when you connected to the Internet, and filled out a profile by registering your first and last names, posted photos or opened an electronic mailbox, your Identity was self-built without your knowledge. And it gets updated with each of your actions on your keyboard....
