    It's not surprising that this has come about again. It has been roughly one full generation of developers since 1994. During that time, those developers who actually learned proper usability techniques either retired or moved on to other endeavors. They knowledge they acquired and the methods they developed have basically been lost to the sands of time.

    Today, we have a whole new generation of developers creating this shitty software. They'll spend the next 10 to 15 years learning what the previous generation had learned. There'll be a few years of good UI design before these developers move on, at which time the cycle will repeat.

    I'm not anywhere near the caliber of UI expertise as Norman or Nielsen. But there's a big advantage to pioneering a new physical interface: you don't need the language part of your brain. My 1 year old twin nephews can interact with their iPads with only the most basic of demonstrations of how a new app works. They can't read or write but they can follow demos of fingers creating action pretty well.

    Is bringing along the old interface of mice & menus helping or hurting? I particularly like the new "swipe up" gesture to scroll down of a touchscreen rather than the traditional "elevator window" model of scroll bars where clicking up scrolls up.

    They are absolutely to be commended for chastising developers that there is no easy way to discover actions if they are not intuitive; I'd rather they come up with ways to address this than just fall back on menus though. For example, Apple included an interactive tutorial for using the custom gestures built-in to Pages, Numbers and Keynote because they aren't discoverable at all. Some I've forgotten because I don't use them (and I'd have to re-watch the tutorials again to re-program my brain). But the ones I have picked up on are absolutely ingrained and effortless now. Unfortunately, built-in tutorials are the exception rather than the rule, and even when they are included they more trouble to refer to than a drop down menu. But there are ways to improve without eliminating gestures.

    I wouldn't want to use the gesture interface when I'm programming during the day, but when I'm swiping through my early morning junk mail, RSS feeds, and to-do items, my brain feels far more engaged on my iPad than my desktop. It's almost like the touch gestures are autonomic and leave my (limited) higher brain functions alone to read though the fog (at least until my caffeine kicks in.)

    I agree that people need to improve gesture interfaces which are in their infancy, but I don't think it's justified to throw the baby out with the bath water just because of long traditions.

We agree. But the place for such experimentation is in the lab. After all, most new ideas fail, and the more radically they depart from previous best practices, the more likely they are to fail. Sometimes, a radical idea turns out to be a brilliant radical breakthrough. Those designs should indeed ship, but note that radical breakthroughs are extremely rare in any discipline. Most progress is made through sustained, small incremental steps. Bold explorations should remain inside the company and university research laboratories and not be inflicted on any customers until those recruited to participate in user research have validated the approach.

Companies spending too much time perfecting their UI design will go out of business while their competitors are shipping flawed but ultimately usable products.

      • UI guidelines should be clear too.

        Point in case: the menu button in Android. It's not guaranteed to do anything: some apps use it, others not at all, and the ones that use it do not necessarily use it in every activity. I'm also "guilty" of the latter part, because some activities really have a need for extra functions (it's a great way to hide secondary and infrequently used functions such as the preferences from the main UI) and others not at all.

      Companies spending too much time perfecting their UI design will go out of business while their competitors are shipping flawed but ultimately usable products.

      There's a difference between perfecting a UI design and inflicting completely new, experimental ideas on unsuspecting users. Testing which particular gesture would be best for each interaction might take too much time, but completely omitting menus (leaving the only way to accomplish anything to be guessing the right gesture) is something that should've been thought over (especially if your target platform ships with a physical 'menu' button).

  • As a retired UI designer, the referenced article reads like sour grapes. The reasons for the "trouble" as posted (lack of established guidelines / misguided insistence by companies / developer community's ignorance) sounds like whining from a standards organization. Old farts always sound this way when someone younger and more bold come up with something new.

    • He has several good points on where usability needs work, though unfortunately is light on suggesting improvements.

      But you must agree with his main point: touch interfaces need work.

      They're off to a great start, now it's time to discover the nuances of actual use (those that can not be discovered in the lab), and improve from there.
