Deci avem un nefericit conflict al modelului utilizator (imaginea va fi inglobata) cu modelul program (imaginea trebuie sa fie intr-un fisier separat), si UI-ul e obligat sa cauzeze probleme.
So we have an unhappy conflict of user model (the picture will be embedded) versus program model (the picture must be in a separate file), and the UI is bound to cause problems.
Dupa cum se vede, modelul program al Microsoft Excel zice ca ai aceste sheet-uri invizibile, una pentru fiecare aplicatie iar ferestrele sunt 'lipite' de acele sheet-uri invizibile.
As it turns out, Microsoft Excel's program model says that you have these invisible sheets, one for each application, and the windows are 'glued' to those invisible sheets.
Observa zonele unde lumea are dificultati, care probabil iti evidentiaza zonele unde modelul program nu se potriveste cu modelul utilizator.
Note the areas where people have trouble, which probably demonstrate areas where the program model isn't matching the user model.
Cea mai populara alegere este cel mai bun model utilizator, si depinde de tine sa faci modelul program sa se potriveasca cu el.
The popular choice is the best user model, and it's up to you to make the program model match it.
E si asa destul de greu sa faci modelul program conform cu modelulul utilizator, cand modelele sunt simple.
It's hard enough to make the program model conform to the user model when the models are simple.
Consecventa este un principiu fundamental al unui bun design UI, dar este doar un corolar al axiomei "fa modelul program sa se potriveasca cu modelul utilizator", pentru ca modelul utilizator este mai probabil sa reflecte modul in care utilizatorii vad alte programe functionand.
Consistency is a fundamental principle of good UI design, but it's really just a corollary of the axiom "make the program model match the user model", because the user model is likely to reflect the way that users see other programs behaving.
Deci, daca muntele nu vine la Mohamed... cea mai buna alegere a ta va fi aproape intodeauna sa schimbi modelul program, nu modelul utilizator.
So, if the mountain won't come to Muhammad... your best choice is almost always going to be to change the program model, not the user model.
Dupa cum am invatat in Capitolul Unu, daca modelul program este similar cu modelul utilizator, ai o interfata utilizator de succes.
As we learned in Chapter One, if the program model corresponds to the user model, you have a successful user interface.
