Department of Science.

Wang Hao and Luo Dayong sat on the sofa together, while Zhu Ping leaned on the edge of the desk and analyzed very seriously, "This is a very small tool APP, aimed at a fixed user group, and those who will not touch the Rubik's Cube will definitely not download it." ”

"You don't have to think about how large the number of users will be, and you don't need to think about how much time users will spend on the APP, it's like a calculator tool software, maybe users are interested in studying it at the beginning, and then they will only open it when there is a need."

"If you want to make money with this kind of APP, the best, most direct and least expensive way is to download it for a fee."

Zhu Ping said it very bluntly.

It is impossible for a tool APP to attract users for too long, and it is impossible to bring much revenue by adding ads internally, and even that the revenue is likely to not catch up with the cost of maintenance, because to add ads in the APP, you need a server to know the specific number of ad clicks, and the maintenance of the server requires a lot of money.

This will bring the cost of running the APP, and obviously a tool-type software is not worth it.

Zhu Ping continued, "If it is an APP that is downloaded for a fee, and it is a stand-alone APP that does not require a server, the research and development direction is very clear, and you can almost only choose the IOS version. ”

Large Internet manufacturers will develop two kinds of APP, one is the APP for the Android operating system of Guge Company, and the other is the APP for the iOS operating system of Fruit Company.

Guge company's Android operating system is an open system, in China, it is almost impossible to do software download for a fee, as long as it is uploaded to the Android operating system software, it is easy to be pirated in various ways, in the way of uploading files, the software can be shared.

Fruit Company iOS OS is a closed operating system that allows users to download apps only from the app store provided by their phones.

In the app store within the iOS operating system, there are also many software that can be downloaded for a fee, such as games, tools, and even dating, news, etc., and simplified software that provides better services can be downloaded for a fee in the app store.

Manufacturers that rely primarily on software download fees as their source of profit will only release iOS versions of their apps.

Wang Hao nodded and said, "If you make an Android version of the APP in the future, it is almost equivalent to using it for free." ”

He shook his head, "However, don't think too far, the core algorithm will be made public sooner or later, as long as the paper is published and the algorithm is disclosed, there will definitely be others who will be able to achieve the same function." ”

After Zhu Ping finished speaking, it was Luo Dayong's turn.

Luo Dayong stood up and said seriously, "Zhu Ping said about the problem of facing users and the direction of research and development, and I will talk about the technical issues." ”

"This APP is only to realize the function of the Rubik's Cube restoration, as long as it can have the core code to realize the function, the rest is actually not technical, and the main difficulty is at the input end."

"There are two ways to input the end, one is to take a photo, that is, to take a picture of the six sides of the Rubik's cube and upload it to the software for image analysis, so that the software can identify the state of the Rubik's cube."

"The other is very simple, that is, to artificially input the color state of each point of the Rubik's Cube, whether it is a third-order Rubik's Cube or a fourth-order Rubik's Cube, there are six color states, but the input is too complicated, and it is necessary to make more than 50 color choices."

"But I just thought about it carefully, I think the previous input method is not practical, if I want to do it myself, at most I can only do a simple architecture, the function can be realized, but there will also be a variety of problems, such as the high requirements for the photos taken by the user, there can not be too many other backgrounds mixed in, and the size of the photo will also be limited, there must be a function of compressing the image in the software."

"Image input is very impractical compared to a tool, which can add a lot of work and crash the software during image analysis."

"Because it's just a small tool software, and there can't be the same type of software on the market, it's nothing if the input end is more complicated, anyway, the user group is only those people."

What Luo Dayong said aroused Wang Hao and Zhu Ping's thoughts.

Indeed it is.

If you add the function of avatar analysis, it will make the software extremely complicated, and it will take a lot of time to spend a lot of time on image research when it is just a simple calculation.

In addition, the image compression function must also be added, because the image taken by the user's camera has a very high definition, which leads to the fact that the photo needs a lot of storage space, and it is impossible for the small software to identify the image that occupies a large space, and the image compression analysis function may be larger than the software itself.

It's not about adding to the snake, it's about adding to the image.

After Luo Dayong finished speaking, he and Zhu Ping looked at Wang Hao together, Wang Hao thought about what the two of them said just now, and felt that there was no problem, and said with a smile, "I am a layman in this regard, I don't have any ideas, what you said is right." So let's talk about income distribution. ”

"There's no need, right?"

"Just a favor! What kind of money to talk about! ”

Wang Hao said with great certainty, "This matter must be discussed first, or there is no way to ask you to help." He paused for a moment and joked, "If you can make tens of millions, hundreds of millions, when the time comes, if you say that I don't pay you a salary, you will become a black-hearted boss." ”

……

Under the rejection of Luo Dayong and Zhu Ping, the three of them still negotiated the income distribution plan.

One option is to divide the account into seven or three points.

Wang Hao accounts for 70% of the income from APP paid downloads, and Luo Dayong and Zhu Ping occupy 30%.

The other is nine, one account.

If there are companies that acquire APP in the future, or have a large amount of income in other ways, Wang Hao accounts for ninety percent of the total, and Luo Dayong and Zhu Ping occupy a symbolic one.

This is because it is definitely the core code that brings in a lot of revenue, and it has nothing to do with other code.

After the distribution plan was negotiated, Wang Hao officially printed three income distribution agreements, and the three of them signed on them, and then the work officially began.

Luo Dayong and Zhu Ping are very motivated, one is because they are interested in developing an APP, and they are very much looking forward to being able to participate in the development of a new function of the APP, and because of the income distribution, they are not optimistic that the APP can make a lot of money, but it is also very good to make a little money.

As an ordinary university teacher, no company will hire them to give lectures, and the pitiful funds that can occasionally be applied for are not enough to even do research projects, let alone make money in them.

They all belong to the type of long-term dead salary, and when they have the opportunity to make extra money, even if they only earn hundreds or thousands of yuan, they feel full of energy.

Wang Hao is also full of energy.

This is his research and his proposal, and it will be possible to make a corresponding APP immediately, that is, to transform the theory into practical application, and maybe make some money, which will naturally be very worth looking forward to.

Over the next few days, they found time to work together in the department.

In the office during the day, Luo Dayong and Zhu Ping will also think about the APP, they are indeed very leisurely, because it is only the first week of school, and their classes are carried out in the second and third weeks, and they almost don't have to do anything in the first week.

Wang Hao is busier than Luo Dayong and Zhu Ping.

The effective and irrelevant carry algorithm is very complex, and it takes a lot of thinking to convert the algorithm into code, but fortunately, the code is designed to crack the Rubik's Cube, and it is better to think carefully or slowly convert it into code.

The process took three days.

Saturday is a busy day.

Wang Hao and Luo Dayong docked the code together, and then studied interface design, functional design and display with Zhu Ping, Zhu Ping left earlier, and the two big men worked until the early hours of the morning, and then simply slept in the teaching and research room.

When she woke up the next day, Zhu Ping had already brought breakfast, and then it was another morning of busyness.

Eleven o'clock.

The design and production of the APP have all been completed.

Luo Dayong held a third-order Rubik's cube in his hand and was ready to start debugging the function.

On the virtual iOS operating system interface of the computer, an APP with a Rubik's Cube icon appears, and the language option appears when you click on the APP, you can choose Chinese or English.

The purpose of this design is to take into account that there may be foreign users to download and use.

After selecting the Chinese mode, you will officially enter the APP, you can choose from two items, one is the third-order Rubik's Cube, the other is the fourth-order Rubik's Cube, click the third-order Rubik's Cube to enter the input page, and select the color of each module on one side of the Rubik's Cube.

Then on the next page, enter the color on the top of the Rubik's Cube.

Next page, color on the left.

Next, right-hand side......

……

After all the inputs are completed, the software enters a Rubik's Cube display page, and the colors of the upper, lower, and left sides of the Rubik's Cube are the same as the colors entered.

On the upper left side, an icon for the direction of rotation appears, along with a prompt, "Twist the left side up 90 degrees." ”

Next.

"Rotate the middle 180 degrees to the right."

Next.

"The right side rotates down 90 degrees."

……

……

Luo Dayong looked at the prompt on the APP, twisted the third-order Rubik's Cube in his hand, and after eleven steps in a row, the Rubik's Cube was successfully restored to its initial state.

The software prompts, "Restore completed!" ”

"Yay!"

"It worked!"

Looking at the restored Rubik's Cube in his hand, Luo Dayong laughed excitedly, "Although I tried it yesterday, it still feels amazing, and there will be many people who will download this APP." ”

"Great! Wang Hao, your program is really amazing. Zhu Ping was very excited, it was the first time she officially participated in 'a project', or a project with the purpose of making money, she also moved her hand and hugged Wang Hao.

Wang Hao felt that he was taken advantage of, but he didn't care about the joy of success, he calmed down and asked, "What's next?" ”

"Then modify the code, package it, and upload it for review."

"Trouble?"

"An hour is enough."

"Go on!" Zhu Ping also recovered her mood and launched an order, "Strive to finish it before lunch!" ”

They worked until one o'clock, and then packaged and uploaded the app.

The next thing is to wait.
