Another way to approach dithering is to analyse the input image in order to make informed decisions about how best to perturb pixel values prior to quantisation. Error-diffusion dithering does this by sequentially taking the quantisation error for the current pixel (the difference between the input value and the quantised value) and distributing it to surrounding pixels in variable proportions according to a diffusion kernel . The result is that input pixel values are perturbed just enough to compensate for the error introduced by previous pixels.

Since every person is different, there’s no one best ergonomic keyboard layout. The standard QWERTY layout is what most people are used to. The Dvorak, Colemak and Workman layouts rearrange the board to put the more commonly used letters closer to the home-key position. All three are intended to minimize your finger movements. That may indeed feel more comfortable and less fatiguing, but people used to the QWERTY layout will likely need to relearn how to type.
