I went to Wuhan newly opened "Guanggu Book City" this afternoon to buy a book, and I saw 2 touch screen queries, and some people were in use. After waiting for an air, it was found that the touch screen query machine of the book city displays the website of the book (www.ovbook.com). The taskbar under this touch screen query machine's Windows system is pulled up, and at least 30 IE windows, and a slow response. It is difficult to use your fingers to pull the task bar back to normal width, turn off three IE windows (find the hit rate of the fork on the top right of touch screen with your fingers), just right next to it Also empty, changed the past. The speed of the other is not slow, the task bar is also hidden, but I am in the Query input box of the book website: How to play Chinese characters / letters on the touch screen? Do you hand in touch screen? Try it, no. Use Microsoft Pinyin soft keyboard? The taskbar is hidden. Use the "copy" function in the menu that pops up with the mouse button? The question is how to simulate the right mouse button on the touch screen with your fingers? It is like this kind of person who is familiar with computer operations. Other people are estimated to be more troublesome, and no wonder people who have left the opportunity. In the helpless, I left the touch screen, depressed into the bookstore ...
On the way back, Lenovo I have previously used the website link type touch screen querger. The urban traffic line query machine of Guangzhou Tianhe Railway Station, next to its display, and a trajectory of laptop to simulate mouse input. Although that huge track ball pushed up not well control, but with the human finger, it can also improve the hit rate of the small button on the webpage. The touch screen query machine of the Wuhan Yellow Crane Tower, there is no small button on the entire display interface, so it is not necessary to use the trackball. However, they all have a common point, all as possible to navigate for users as much as possible, and have no user to fill in the input box.
In addition, I have encountered a similar question when I participated in the MCSD exam, and the topic is roughly as follows: Among the users of a software project developed, some users have poor vision. In order to facilitate this part of the user's use, what should you do? The options are as follows: A. Using as big fonts B. Invite users of various vision to participate in the test C. Invite almost unacceptable users to participate in testing ...
I chose B. Among the actual projects, similar situations, if the conditions permit, I will do it as much as possible. Although I don't want to sing a song for Microsoft, from this topic, Microsoft's products have considered in humanization than most software developers in our country, so they are not enough in competition. Odd.
It can be seen that when designing the software operation interface, there is a need to pay attention to: 1, must consider the input / output device used by the user; 2, as much as possible to a relatively easy, free operation interface; 3, the user must be accidentally destroyed during operation, how should we deal with this situation, can we deal with it, will not make users feel troublesome next time; 4. Want to consider all kinds of users, don't put some one Small part of the user's operation is used as all users.
