Recently, foreign media The Mainichi reported that Hiroyuki Ueda, a 63-year-old engineer from Japan, tinkered with calculators on computers after retiring. Some people may say that calculators on mobile phones and computers have already appeared. If we repeat the research, wouldn't it be reinventing the wheel again? What's the point?
这款计算器与我们常见的计算器有所不同，Hiroyuki Ueda 研发的这款名为 Twin-Calc 的计算器应用，是一款将两个计算器二合一的产品，简单来看，就是可以在同一个界面显示两个计算器。
Of course, it makes sense to display two calculators on the same interface. This dual calculator application allows users to click the "left and right green arrows" in the middle of the screen to directly import the output results from one side to the other.
For example, if you enter "89*15" on the calculator on the left, click "=" and get the result of 1335, and then click the green arrow to the right, then 1335 can be displayed directly on the calculator on the right ,As shown below:
In addition to this, both calculators can also perform different calculations. For example, when a user wants to know which store has a cheaper product, they can use simultaneous calculation to compare prices, which is also very convenient.
This design is very practical. Mr. Xiaoshu said he wanted to use it, but the author’s phone is an Android phone! ! ! ! ! ! !
Based on the concept of the software design, Mr. Xiaoshu added this function to the WeChat applet "Moment Photo Album" after adding historical record viewing and layout adjustment.
In order to facilitate user experience, the calculator is adjusted to an up-and-down layout, and the blue and black calculators are designed with different color blocks:
1. Click the "Move Result Down" button on the blue calculator to move the calculation results to the black calculator;
2. Click the "Move Result Up" button on the black calculator to move the calculation results to the blue calculator;
3. Click the "History" button to view the calculation history.
