Clickable UI elements with absent or weak visual signifiers condition users over time to click and hover uncertainly across pages—reducing efficiency and increasing reliance on contextual cues and immediate click feedback. Young adult users may be better at perceiving subtle clickability clues, but they don’t enjoy click uncertainty any more than other age groups.

Even as more sites mimic swiping gestures and incorporate horizontal scrolling in desktop designs, users remain reluctant to move sideways through content.

Predictable Target should appear high on your list of mandatory rules, only to be violated when it can be proven that another consideration, in a particular circumstance, will result in even greater productivity.
"User experience" encompasses all aspects of the end-user's interaction with the company, its services, and its products.

A reader asks for advice: "Why on earth we seem to want to browse or scroll long lists to find something when typing into a search box is so much more efficient?"

What users believe they know about a UI strongly impacts how they use it. Mismatched mental models are common, especially with designs that try something new.

The killer app for the iPhone/iPod Touch is the App Store. 85,000+ apps have been written and, via the App Store, 2 billion copies of those apps have been downloaded. Apple gets 30% of the revenue; the developers, 70%. Everyone has been making a lot of money.

In Part 1, I discussed the ill-effects to the Macintosh of Apple's Flatland aesthetic, a visual simplicity that threatens to bury Apple's users with unnecessary clutter and complexity. This month, it's time to turn our attention to Apple's other devices, beginning with what users are faced with when it’s time to upload images.

Appleland is becoming progressively flatter and, at the same time, less usable. Properly-designed interfaces scale, so that they support the new user as well as the expert.

The typical web experience is a series of slow, stuttering steps, punctuated by moments of utter boredom. We can do better, and we can do it without faster processors, servers, or networks. How? By taking advantage of subjective time.

In parallel design multiple designers independently of each other design suggest user interfaces. These interfaces are then merged to a unified design. In a case study, measured usability from version 1 to version 2 was improved by 18% when using traditional iterative design and by 70% when using parallel design.

In 4 case studies, the median usability improvement was 165% from the first to the last iteration, and the median improvement per iteration was 38%. Iterating through at least 3 versions of a UI design is recommended, since some usability metrics may decrease in some versions if a redesign has focused on improving other parameters.
