10 internets ago, I made an otterpost about custom keyboard layouts, ortholinears and maybe a little about ergonomics. So, I decided to go further into what ergonomics, as someone who knows absolute nothing about ergonomics and didn't research on anything. Treat this as if a drunk fisherman who is also potentially mildly to extremely racist wrote it, maybe there's something interesting innit but it's going to be mostly me venting about HCI and fuck tits poop balls type shit. Unless if it's something custom made for you, ergonomics is usually business manipulative term that means "This thing looks fucked, you are better off using alien tits for this. We don't even know how to sell this to anyone human". I could be trying to subliminally sell you shit.

Before going on about ergonomic devices, the most important advice ANYONE should be giving is looking at your desk and your posture: How close is your keyboard and mouse to you? Is it close enough to where you can use it without stretching your arms or angling your forearms? Is your desk tidy? Do you put the most common used things close to you and shit like diaries and pens further away from you? If you answer no to any or all of those questions then you probably can improve your ergonomics without spending le dollah, shit's like geometry. No, you don't need your cleanex near you, you absolute wanker dumb cunt.

Desks? Get one of those 2000s slidy tray desks, especially if you're short, they're the best and it makes it evident what should be in your primary area (close to you) and your secondary area. And the cool thing is, no one wants them! So, you might even find them for free! Slide that fucker out and you're not only an arm distance away from your screen but these desks are designed like NASA, okay? Those rgb desk bullshits are pure masturbation.

Chairs? I don't know, I don't care for now, I literally use a camping chair with a bunch of pillows for height because I'm short. Though, you could get your ass out of that chair, go walk. Go have a coffee and look outside, otters need to move.

Keyboards? I think you should start with literally any cheap 60% keyboard, this allows your mouse to be closer to you and makes you use layers for keys that you would have to cross the pacific ocean to use anyway. Unless if you are using a ottermak ;), I do not recommend ortholinear keyboards, especially at smaller sizes. I do think that split keyboards would be a bonus but they're quite expensive since it's only keyboard hipsters who use these therefore every single one of them are hypefapped to oblivion. Wristwests are a waste of money, don't rest your wrists on your keyboard, you have your desk, your legs to rest your wrists on.

Mice? One issue one could have with normal mice is using their wrist for everything and not engaging other hand/finger muscles. A vertical mouse forces you to position your hand in a handshake type position, which is technically better? Except that they're bulkier and heavier. Moreover, buttons are usually harder to press and positioning is even more important as your hand has to mold into the mouse. Using a vertical mouse hurts my hand, because palm position isn't my weakpoint, it's the abuse of my wrist and thumb area. I find that using a smaller, fingertip-optimized mouse more ergonomic, as it engages my finger muscles more evenly and is lighter. I can't tell you anything about other types of mice but before buying a fingertip mouse, get something like a matchbox and try to use it in a fingertip grip for like a little, how does it feel? Do you feel it needs to be taller, shorter, longer, thicker? If so, find something else in your household, be creative. If you still don't like it then it's not for you. Playfulness is actually a really useful thing in life. Southpawing a mouse can be helpful and that's free.
A vertical mouse feels like a handshake, a normal mouse feels like doing calligraphy, a fingertip mouse feels like using a pen. That's what I think.

Screens? If you work with a lot of text or require verticality, get a 5:4 monitor, again, just like the 2000s desk, they're often free and they are objectively better for work, most applications are still optimized for "fullscreen" monitors, not widescreen. If you don't like it, you can give it to someone else, to me preferably. I think that a vertical 16:9 is too much (unless if it's like a small screen, I guess). Again, they're so unwanted, that you can find them for free.

Don't listen to anyone about ergonomics, don't listen to me, just try things, I put no effort in this post, I just wrote it. I can't personally tell you what is good, I can only tell you what I like currently, I'm not a model for ergonomics. I'm also known for being kinda extreme in my peripheral preferences, of course, I'm always objectively correct about my opinions but it's okay to have a wrong opinion :)

"Ergonomic devices" are only ergonomic if they lessen the strain of your weaker points and if possible, add an extra dimension of movement where you're stronger and most of all, appropriate for what you're doing. If it's something physical, it's going to strain you in some way, there's no escaping that.
