Testing methods for usability of design elements

Web page Production WEBJX article introduction: the ultimate usability design of the mobile interface.

Alan Cooper about face a book provides a test method for designing element usability : Remove elements from the design like the one in the interface until the design collapses ...

In particular, mobile internet equipment, because of small screen, operating environment complex, electricity and other conditions of the restrictions, we seem to have a good reason to achieve the ultimate design.

What is the ultimate? The ultimate is a trade-off, from the space and time two dimensions of the design needs of the choice.

In each received product demand, for each function point under each element, the right choice to have the ultimate possibility, otherwise can only be mediocre!

Anyone who has ever used an iphone may be impressed by its elaborate design from hardware to software. When I called and gently put the phone on the ear, the unexpected discovery of the screen darkened, after a few seconds, the screen lightened.

This very intimate design considerations, I think, but contains a simple and profound philosophy of design: From the time dimension, mobile phone affixed to the ear, the entire mobile interface of the effectiveness of 0, the interface from the design to take away from the point of view of the requirements, not because the interface of the "removal" and the function of any missing.

In the LBS business specific design, many colleagues for the map and list two different views, the pop-up box display POI information, and began to "dispute" whether the map blocked, if you want to see the map there is no way. This time the imagination of the user is like "super versatile", it seems that everything should be placed in front of him for a rainy day, the actual situation is really like this?

I think, in terms of the time dimension, users can only do one thing, after all, a brain can not dual-use, may be a lot of people are afraid to find the entrance to do another thing, in fact, as long as the guarantee of a thing and another thing of continuity, the effectiveness of the operation, with Don t make me feel a book saying, The number of operations is not a measure of the complexity of the operational task of the standard, three effective operation of the meaning of more than one invalid operation! (I understand this effectively, every step of the operation, the user is very clear about his current location, the results of the operation, the reasons for the operation).

Input Web site or keyword search (search engine) is the Internet to find information commonly used two methods, QQ mobile phone browser iphone version is not unusual for it (many other browsers and QQ Android Browser has designed two input boxes), because for touch-screen mobile phones, The user input content before the necessary operation is to touch the input box, then all the truth, the original is such a search!

Of course, these two design methods are acceptable, but only by this example, we in addition to space permitting, the design elements of the rational layout, can also be based on the operation of the necessity (concept of time) reasonable space use.

The author of Don T make me thought is a driver who prefers the traffic signs in Los Angeles, which I think is indicative of a high concentration of consistency that leads to operation! In the dimension of time, these indicators of information effectiveness to the extreme of the reminder: neither because of too much advance instructions to increase the burden of memory or confusion, nor because of late instructions to delay the driver's judgment.

When faced with a large area of demand list (feature list) to be displayed on a page or a series of pages, I think there is a priority.

There is a special kind of information: it's not particularly important, but it still needs a portal to find it, like the business hours of the supermarket or the operating hours of the subway, although most of the time (now discussed by the most ordinary user) in the normal business hours, directly to the supermarket or take the subway, Without paying attention to business hours, but we can find it as soon as we need it.
