A good reference. Thanks.
I like Interface Zen - much sense there.
However, there's a case he missed, probably through never using a CAD
system. All the good ones can be driven either by mouse, or by
non-chorded key sequences or any combo the user likes. The essence of
CAD is very accurate pointing but all too many mice move slightly when
clicked. Fortunately a decent CAD system offers the possibility of
purely pointing with the mouse and doing everything else with the other
hand on the keyboard. The result is both fast and extremely accurate.
An interface design point that nobody has yet mentioned here is that
there are four different types of user that map onto a grid:
casual dedicated
untrained 1 2
expert 3 4
I first ran across grid this in "Design of Man-Computer Dialogs" by
James Martin and its been very useful in systems interface design.
The problem with almost all current GUIs is that they are aimed at types
1 and 3 users - this certainly applies to Windows, OS X and Gnome
desktops with the emphasis on type 1. vi and microEmacs, OTOH, are aimed
at type 3 and 4 users.
Where does emacs fit on this grid? My guess would be 3 and 4.
Its very difficult indeed to design an interface that suits both
untrained and expert users. About the closest I've seen have been
keyboard driven menu structures which have been designed so the user can
build their own "command sequences" that traverse menu levels without
showing the menus, as long as items are selected correctly from each
level. Many CAD systems approximate to this but I've yet to see a
graphical desktop, IDE, or editor menu structure that came close.
