Ouch Ouch UIs: WWTT
Saturday, August 30th, 2008Modern user Interfaces are designed by engineers for engineers, and hence for most users are terribly inefficient: we desperately need to make them simpler. Society will not advance unless we do.
I see so many UI terrors all day: mortals just do not get how they work. I see this in daily life with inexperienced PC users, and I see it even more in digital cameras, both SLRs and point-and-shoots.
First a few examples in PCs and other ordinary user devices:
- Why does the on-off switch of a normal computer need you to hold it down for four seconds to turn the computer off? All very cool and stuff, but what were they thinking: people like my mother will never figure this out. An on-off switch should be a toggle with two clearly marked positions, “ON” and “OFF”. What you do behind this (eg shut down gracefully) is up to you, as long as it is clear to the user that ON means ON and OFF means OFF.
- Volume control sliders. These are terrible and offer no measure of control. A volume control should be a rotating potentiometer, not a slide.
- The USB connector. It only fits one way, but you cannot tell which way until you try - so, 50% of the time you insert it wrong. Again, what were they thinking.
This is pervasive. The Windows “Start” to “Stop” is another schoolbook example. I see these so often that I have started calling them “WWTTs”, for “What Where They Thinking”.
In digital cameras, I see the same users make the same mistakes day after day, and always in the same places. Why do camera designers not do focus groups? Some examples after you click on…:
