Repetitive pressure accidents (RSI) is usually a actual ache. You’ve received a shiny new laptop computer, and all the pieces’s going easily, however abruptly you possibly can’t use it with out agonizing (as in typing-speed decreasing) ache attributable to years of keyboard bashing or simply plain dangerous posture. All of us hacker varieties will doubtless have or will expertise this in some unspecified time in the future, and by chance there are a lot of potential options.

[Zihao Wang] writes to indicate us kseqi, one other chord-like textual enter technique, with a concentrate on the enter sequences, versus any specific mechanical association of keys. The concept is to utilize two units of unbiased inputs, the place the sequence of actuation codes for the keystrokes to be emitted into the applying.

An instance interface can be to rearrange two units of 5 keys because the enter mechanism. One can prepare characters in a matrix. The left secret is pressed and held first which selects a column (1 out of 5) then the proper secret is pressed to pick out a row, and thus a personality. Subsequent, you launch in the identical order, left, then proper, to ship the character.

Swapping left and proper permits a unique set of characters. On this easy scheme, fifty characters might be coded. Take a look at this internet meeting demo for the way this operates. Swapping out the bodily inputs for a pair of joysticks is another choice, which can be higher for some of us with particular bodily difficulties, or perhaps as a result of it simply seems enjoyable. As [Zihao] mentions within the write-up, the sequence order might be modified to code for different character units, so this straightforward scheme can deal with many extra character codings than this straightforward instance. All you must do is keep in mind them. events might want additionally want to dig into the kseqi Rust crate for info.

Chorded keyboard tasks are plentiful on the market, right here’s a pleasant Bluetooth-connected keeb, and one other one which’s all wiggly.
