A programmer brother Caleb Have a son recently , But troubles also follow .

Newborn Baby Feed every few hours , If you are hungry at night, you will cry loudly , At this time, the whole family was woken up , I can't sleep well after being tossed all night .

He consulted experienced people around , All the suggestions are ：

Bear with , Just survive the first few months .

but Caleb As a programmer, I'm not willing , He began to use his engineering thinking to solve problems .

Final , Through the camera +AI Combination of algorithms , He came up with a set Automatic baby hunger detection system , It can be found in time before the baby really starts crying .

Caleb Once the program determines that the baby's hunger probability reaches 100%, Just send a notice to his mobile phone .

So he can get up quietly and feed himself , He guarded his wife's sleep with technical force .

Such a system does not need to be developed from scratch , Because the ready-made human posture detection algorithm has been very mature .

such as Caleb Using Google open source MediaPipe, Including the whole body posture 、 Facial mesh and hand motion detection .

The rest of the problem is ——

AI How to judge whether a baby is hungry ？

Before we start to work ,Caleb First, I went to the mother and baby forum to check a lot of information .

According to theory , Crying means that the baby has entered the late stage of hunger . At this time, it is not easy to feed directly , You need to calm your baby first .

Early manifestations of hunger also include smacking （Smacking） Or lick your lips , Repeatedly open your mouth and shut up , Suck your lips 、 Fingers or other clothes, toys, etc .

Caleb According to the experience of observing your own children , Writing code separately gives these behaviors different weights .

For example, smacking your mouth will +10% Degree of confidence , Put your fist to your mouth +10%.

And the baby's turning back and forth means that he is looking for a food source , He observed that the frequency of his baby's turning around varies according to the degree of hunger .

So he set it in a short period of time , The more frequently you turn your head, the more confidence you increase .

in the meantime , I've also encountered that babies with pacifiers in their mouths will cause shelter , The algorithm cannot accurately recognize the lip movement .

Therefore, he retrained his customized model based on the open source algorithm , The confidence is given according to the situation of holding the pacifier and not holding the pacifier .

In the process, he also found , The baby will spit out the pacifier when he is extremely hungry . This action will fully increase 30% The degree of confidence , The representative is about to cry .

After this system is put into use , Do give Caleb Your family brings many benefits , He concluded. ：

The baby is happier , Adults can also sleep more .

however , The story is not over yet ……

Automatic feeding system is not feasible ？

With the preliminary results of software , Did not satisfy this elder brother DIY The soul of .

Next, he put the system and hardware 、 The mechanical devices are linked together , Try to create a Automatic feeding system .

It's a bold idea , But judging from the ending, it's still a little Superclass 了 .

He also knows that this thing is prone to accidents , So first find an adult to act as a baby to do the experiment .

I saw him repeatedly turning his head and smacking his mouth in imitation of the baby's movements with a pacifier in his mouth , Let the system improve confidence , Finally, spit out the pacifier to trigger the system alarm .

What happened next , Just one word “ Dangerous action , Do not imitate ”.

Caleb Make a video of this experience and share it online , In the programmer circle 、DIY Circles have attracted attention .

He revealed that it took only about 50 Hours , because MediaPipe Open source tools have been very perfect .

"Some netizens commented ： If I develop this system , When I finish, the child will already be able to make soy sauce .

Caleb There is also a reason why it can be done so fast , He is already familiar with the development process of target detection application , Before, I also tested when the dog pulled Baba in my yard .

For his practice , Some people feel strange .

I'm hungry → Must cry → Get food , This should be learning to interact with the surrounding environment 、 The necessary stage of communication with parents , If you just lie down, you can get food , Whether it will affect development ？

Another netizen thinks , The professional advice he gets from parenting classes is to try to feed babies before they cry , So the problem should not be big .

Caleb I also said , He and his wife will not completely rely on algorithms to decide the world of feeding children , It's just that AI help , They can raise children more efficiently .

Of course , More interested netizens are urging him ： Fast open source ！
