Embodiment 1

[0071] Use ten number keys from 0 to 9 and some function keys to input the text message content.

[0072] During the SMS input process, when calculation is required, the calculation module can be started in the two ways mentioned above. After inputting the numerical code, the possible matching operators will be displayed in the candidate area. If the desired operator is on the current page of the candidate area, you can use the left and right arrow keys to select the required operator, and press the "OK" key Then the operator is selected. If the required operator is not on the current page, you can use the down key to turn the page to find the required operator, or use the "*" key to open the mathematical constant and symbol table to select the operator. Then enter the encoding again...and so on. After the input of the expression is completed, the current expression is displayed in the coding area. At this time, you can press the "OK" key to calculate. If the current expressi...

Embodiment 2

[0090] The difference from Embodiment 1 is whether to display the mathematical expression when displaying the result. If the current expression is valid, press the "OK" button to calculate the value of the expression in the calculation module. The display module does not display the expression, but directly displays Calculation results.

[0091] Still taking the input "Hello, your deposit interest this month is 28500×0.45%=128.25 yuan" as an example, steps 1-11 are the same as those in Example 1, and step 14 should be:

[0092] 12. Press the "OK" key to calculate the value of the expression, and the calculation result will be displayed on the screen. The current displayed content is "Hi, your deposit interest this month is 128.25".

Embodiment 3

[0094] The difference from Embodiment 1 and Embodiment 2 lies in the way of starting the calculation after inputting the expression. In this embodiment, after inputting the expression, it is necessary to select the symbol "=" in the candidate area to calculate the value of the expression. After the symbol "=" is confirmed, the expression and the calculation result are displayed in the result area.

[0095] Take the input "Hello, your deposit interest this month is 28500×0.45%=128.25 yuan" as an example:

[0096] Steps 1-11 are the same as the steps in Embodiment 1, and step 12 should be:

[0097] 14. Press the number key corresponding to the serial number of the symbol "=", the symbol "=" is selected, and the symbol "=" is displayed in the result area while the expression is displayed, and the calculation result is displayed at the same time, and the content displayed in the result area is "Hello, your The deposit interest for this month is 28500×0.45%=128.25”.

Abstract

An input of text real-time calculation method and technology by numeric keypad, this method includes the kinds of information input and the input are all the unitized numeric code. During the process of text input, the same engine calculation function is started by the operation of function button. Under the same interface it can directly do real-time calculation, input and edit calculation process, mathematic representation or directly input the result. When the above calculation function finished, the input system can automatically be back to the original mode and go on the text input. This invention is suitable to the mobile-phone, Xiao lingtong, PDA, hand computer, IPTV, roof case, video game so on.

Description

technical field [0001] The invention relates to a calculation method and system in the text input process, in particular to a real-time calculation method and system in the numeric keyboard text input process. The present invention is applicable to various digital keyboard electronic products such as mobile phones, PDAs, PHS, IPTVs, set-top boxes, remote controllers, and game machines. technical background [0002] With the promotion and popularization of digital keyboard electronic products such as mobile phones and PDAs, the forms of information content exchange are becoming more and more diversified, and human-computer interaction services such as online banking, mobile payment, mobile settlement, mobile stock trading, and TV payment are also constantly increasing. develop. These businesses necessarily make computing a necessary requirement. Therefore, information exchange using terminals such as mobile phones, PDAs, TV set-top boxes, and remote controls is increasing d...
