Like how tf does one play Doom on a pregnancy test???????

Note, the pregnancy one wasn’t actually on a pregnancy test, but let’s pretend it was on some “smart” pregnancy test device.
Computers are computers. Doesn’t matter if they are a laptop, desktop, camera, fridge, tablet, pregnancy test. If its got electronics that can compute, kt can compute anything. To interact with the computer, we as humams use things called shells, you are likely familiar with operating systems like windows, linux, or macos, but phones and tablets have android or ios, and cameras/iot devices have their own os on them. These more specialized operating systems are designed to do the thing their device is designed for an nothing else. The developers of these operating systems do not let you install other programs on to the device like you can on a windows computer. There’s no need to. (sometimes cameras or other devices might have their own app store like the play store or app store on Apple) But, underneath that specialty operating system is still a computer that just understands ones and zeroes, it really doesn’t care if it computes photos, pregnancy results, or doom. So people will find vulnerabilities in the device to exploit and put their own operating system on the device, one that can run doom. They might need to tinker with the operating system a bit so that it looks for the devices screen and buttons (since it might be looking for a typical monitor and keyboard for example) , but if the official camera operating system can recognize what to do when a button is pressed, there’s no reason that this new operating system can’t be written do the same.
TLDR: The computer underneath these devices doesn’t care about what they are computing, whether that be doom, or anything else. To it, it’s just following instructions. The hard part is finding a way to send new instructions to the computer as manufacturers intentionally lock the “doors” to the computer or just dont put a “door” in at all.
