The problem is the “uninformed” part. Where do you communicate the logic behind the interface, when it goes beyond grouping modules by function? In this case, the pipeline order. It is explained in the manual, but new users have to read at least part of it. But then they are no longer “uninformed”.
And getting users to read a manual is hard, which is perhaps why camera manufacturers don’t bother anymore beyond the bare basics (of course, not providing a paper manual being cheaper as well, might have played a role…)
Indeed, most can get along with about any user interface that gets thrown at them if they have to (and I’ve seen some “nice” ones on expensive scientific equipment I had to get along with…). But in case someone finds an interface suboptimal, there are at least two possibilities:
- the interface is bad;
- the way the user thinks/works doesn’t fit with the logic behind the interface.
Figuring out which of the two is relevant in any particual case requires the users to have some experience with the interface under discussion, as an unfamiliar interface will always feel clumsy. Even more so when the user has previous experience with another program from the same category (e.g. lightroom).
