Avoid input

Often users complain about the iphone's input button is too small, difficult to click, the phone's input speed has been a difficult point. Therefore, the mobile phone interaction design to appear in the input box, we should focus on how to reduce input, improve user operation fluency. In addition, the mobile phone's display ability is limited, can not like the Web page to provide a large number of options for users to choose, each interface must provide the most valuable information.

Provides options. The characters that users often enter can be refined into popular options for easy user selection.

For example, the use of mobile phone to buy digital point cards, for the purchase of a large number of popular point cards (Warcraft and Q-coins, etc.), QVGA (240*320 pixel) mobile phone can provide 10 options. If the user has purchased a certain type of goods, you can replace the hot point card data, using the purchase record and popular point card combination method. The digital point card belongs to the user to repeat the consumption of goods, and tickets, movie tickets and books are not repeated consumption of goods, such as the purchase of such records placed on the home page enough user choice is meaningless.

Hot options must be "hot", such as 10 clicks of 30%, that can reduce the http://www.aliyun.com/zixun/aggregation/18678.html of 30% "> user input, that will reach the purpose of the popular option." But if the popular option hits less than 10%, it's a waste of mobile phone's limited display space.

Too many options are inconvenient to find, as well as direct input.

The memory of the control. Record the characters entered by the user in the input box, the iphone input box can be added to the "bookmark" function, you can remember all the characters entered by the user. Click "Bookmark" to enter the table view or custom pop-up box, which is listed in the order in which they are entered in chronological order.

The data you enter must have a filtered procedure and will not be saved for worthless input characters. such as mobile phone recharge function users fill out 10-digit mobile phone number, click the "Recharge" button, mobile phone clients to remind users to enter the phone number format error, at this time the 10-digit mobile phone number should not be recorded.

Use mobile phone system information. The phone's address book contains information such as name, phone number, and address, which can be invoked when filling out a form. For example, when recharging for a friend's mobile phone, need to find the phone number in the Address book, and then back down, open the program to find the phone recharge function and then enter the mobile phone number. If you can call the phone address Book, click on the phone number of the icon to the right of the box, enter the address book to choose the friend's mobile phone number.

Quick Find. The iphone's address book has the ability to look up names by initials, making it easy to search through large amounts of data. If the purchase of air tickets to search the city, can provide city cheap first-letter search function, input "N", Filtered out "Nanjing" and "Nanning" and other cities.

Reuse of data. For the same type of characters can be reused, such as the passenger information to fill in the ticket, you need to enter the mobile phone number, you can call the phone recharge function has been entered in the effective mobile phone number.

If input is unavoidable, you can boot user input, such as informing the user of the role of input data. It is valuable to provide users with effective information after input, and to let users feel that it is time to enter.
