Injury or recovery
A fracture, burn, surgery, or anything else that takes one hand out of rotation for a while.
Typing with one hand
One hand is enough.
Not a reduced keyboard. Not a clinical interface. The same keys, the same Mac, and a different physical route to every letter.
Why it exists
The origin was ordinary on purpose.
The first use case was simple: one hand held a burger, and the other still needed the whole keyboard. That small inconvenience exposed a bigger design assumption—that everyone has two hands available, all day.
Hamburger Keyboard treats one-handed typing as a layout choice. There is nothing to disclose, no special hardware to buy, and no interface that turns a person into a diagnosis.
Who it can help
Different reasons. The same missing half of the keyboard.
RSI or chronic pain
When reaching and stretching are the problem, bringing the far keys closer changes the movement.
Limb difference or hemiplegia
Choose a stable hand during setup and make the mirror your everyday keyboard—not a workaround.
A hand that is simply busy
A baby, a phone, a coffee, a handrail, lunch. Convenience does not need a medical justification.
The first stretch
You know the layout. Your reflex needs a minute.
Your fingers already know where the far letters live. The mirror uses that knowledge, but it still takes practice for the opposite key to feel automatic.
- At firstYou think through each mirrored key.
Slower is normal. Accuracy matters more than speed while the physical map clicks.
- With practicePairs start becoming one movement.
Short, real-engine drills show the keys to press and keep tutorial text out of personal learning.
- In daily useHamburger fades into the menu bar.
The app keeps correcting while the window is closed, with quick hand and pause controls nearby.
Access matters
If price is the thing in the way, say so.
Anyone who needs Hamburger and cannot afford it can ask for a free license, without explaining or proving their situation.
