Re: [LAD] User eXperience in Linux Audio

Hi *,

Some good points, and interesting points of view. @Thijs van Severen:
I completed various UX / UI modules during my undergrad - that,
together with the most obvious lacks (IMO) of Linux Audio UX is what
prompted my composing of that exact list.

Yes - both very good points. The latter (crashing on open) is
particularly important, because if no splash exists, users expect the
app is broken.

Agreed, it is not the ideal situation, but it is much improved over no
indication of feedback. Although a power-user probably won't care much
for a splash screen, to novice users it does provide "visibility of
system status", #1 from Nielsens UX heuristics.

RE Dial Interaction:
@Vytautas Jančauskas - For on stage use, I concider anything except
"slider" style interaction with dials completely useless. I propose to
any project using "radial interaction" style widgets to switch to
"slider style" interaction.

If moving 4px can cause a value jump by 50%, it is not safe to
interact with that dial during a performance. Gain knobs are common
offenders here - particuarly in Distortion / FX plugins. "Slider"
style interaction has no disadvantage in the on-stage usecase, hence
any OpenAV software (and AVTK) have the slider style interaction.

>> RE Blender UI:
Its very complex yes - its also pretty cool in the features it
provides. Hotkeys to hide and show parts of the UI are a nice touch
for power users, and a lot of work and thinking has been put into the
UI. I'm a fan - but I'm a long term Blender user, so I can't
objectively comment on how UX freindly it is for novices..

>> Re Radial Dials:
Is there a disadvantage to "slider" style interaction here? Set a
middle rate of change, and allow the user to use various hotkeys to
increase / decrease it? This avoids the "4px 50% jump" issue, which is
IMO catastrophic for live-use.

Cheers, -Harry
