My confusion with this post is that it already exists? It’s just your home screen on your phone.

Ergonomic, supports a variety of functions (adjusting settings, running applications, customization, viewing device info), is loosely standardized (much like terminals across OSs), and widely adopted.

The only difference is touch interface vs. Text interface.

Like what are you actually looking for? A gesture controlled terminal or an interface? You already have the latter.

Also, if you’re not in a rush, just email the authors!

A vast majority of professors and researchers hate the publishing industry as much as anyone, and will be happy to shoot you a pdf if you’re interested in their work!

It’s definitely not a contraction.

-er is the agent suffix in English. Effectively it turns words into those who do something related to that word.

Hawk > Hawker = One who “hawks” Run > Runner = One who “runs”

In principle this implies the existance of a verbal form of the root word, such as the two above examples.

Witcher, as used by the fantasy series, is a weird one because it’s actually not related to the agent suffix.

The Polish title of The Witcher is Wiedźma which just means “witch”. When it was translated to English they adopted “witcher” as a masculine form to the oft feminine “witch” by using the ability for the -er suffix to indicate a profession or association with a noun in English i.e. Cash > Cashier, someone who handles cash/payments (actually derived from french with the -ier suffix, but point still stands). In the cass of Witcher it is one who works as/with witches or else one who is associated with Witches.
