Do you want your coffee to pour the kettle on? Probably not. Having both handles spill hot coffee in his hand, two hands to grab the jug of a scorching palms. Thus, it can be a coffee pot on to say that it's not user-friendly. If you want your products to be designed and a lot of happy users of the peace, to be thinking about usability or usability apart. I mean the most common everyday things that are around moulin us. From a box of pasta to your table, ending with, you want to open, close it. What are designing based on?
This is what the user is comfortable, understandable and logical, has been studied for several decades. Which principles should be based on the design of it? Give feedback - the user must be able to design products for immediate and clear feedback. When you turn in your kettle, moulin light will be lit. Thus, you know that the machine began to work. Bring the real world of design - the design should speak the language of the user, and based upon his habits and culture. We know that the hot water from the tap to the left side and the right side of the cold water from the tap. Not smart to force users to learn the opposite, or something else altogether. Tap to put a label on how to use it? MEAC. To ensure user control and freedom - a user often makes the so-called finger berths to allow him to improve his mistakes. Are accidentally deleted an important file of the text? That's okay, fortunately, there is an undo. Building on the standard test - do not start to reinvent the wheel. If a user knows that a green light means "okeid", there is no need to change the color of an orange. Preventing errors from occurring - this is the perfect moulin design with no faults. Wise's mistakes before him, and all the scenarios before launching them enough to test the product. Human beings make mistakes all the time. Thus, for example, from the user to ask: are you sure you want to delete this file? Sure, sure? Do not make remembering - give the user a simple and specific instructions - he did not want to think and remember. This refers to poor design: "I do not remember how the digital moulin TV channels in the sequence was modified. I tried it a few years ago to do, it was so complicated and confusing. After that, have not tried. Let stays as is, it does not matter. "Tea important to be visible - if a person is caught between the double glass doors, it's not his folly, but a bad design. User should look like, which are located in the hinges, the door must be either pulled or pushed, and with a handle. Point to help - even if the design is close to perfect, the user must have access to support materials. It should not be too bulky to be easily discoverable and understandable, and arranged in categories. Feedback and learned helplessness
Adherence to such principles, it seems pretty easy, but still we face every day with such a poor design, or coffee cans. This phenomenon can not be underestimated, because, for example, the cause of the crash could be bad design.
All previous story, of course also applies to online environments, which has long been commonplace to us the same as the opening of the door. Recently, one of my Facebook contacts wrote on your wall: "Right now, it takes only a page ltkh.ee itk.ee and ridiculous about a hundred clicks to suck onto the desired thing to find, but, after all, can be done on a much more complex, it would encourage moulin continuous excitement. Instead, in order to provide vital information to me to be entirely for the letter, as there are number of beds in the hospital, many of them are in the ICU, etc.. Scantily-average moulin computer literate patient may want peace of mind off the computer at home to die. "Today is a good opportunity through forums, social media, etc. to give the designers / developers constructive moulin feedback, which is normal for any trader who wishes to remain competitive and to hear the takes. Use this opportunity.
Much has been written moulin about in the learned helplessness of. If you encounter a complex system, which seems to us the unaffordable, do not give the desired result, or even a few causes of the accident, we put it in own fault. "I fit my old cable and dial the phone. The wireless phone is a complicated, I do not know how to load and can not be put Muuga never make it. "How big a part will give us realize that it is a bad design, not our stupidity?
Post at the beginning moulin of the "Masohhistide coffee pot" belongs to the French artist Jacques Carelman created by the "impossible objects" (Impossible Objects) series. Image has become famous thanks to the 1988th was published, and the designers have achieved a cult status among the book The Design of Everyday Things. Coffee Pot is currently the only Carelmani created by the things that you can also buy (the price of 300 U.S. dollars).
