More visually appealing charts on Appraisd. There are many ways of representing performance data and this is just one of them. The design treads a fine line between bombarding the user with data and keeping it simple. Too simple and the wrong conclusions can be drawn by the user unless they're skilled in statistics and numerical analysis.

Why does this Barclays cycle hire keypad have fingernail indentation marks on it? A very simple UX case study.

I used one of these bikes the other day and while in parts it's brilliantly designed, there were several key user-experience problems. This photo illustrates one of them.

The reason there are fingernail marks on the numbers is because there's no feedback - mechanical or electrical - when you touch the buttons. As you can see, users to try to press it as hard as they can to get it to register their choice. It turns out you don't need to press hard at all, but users have no way of knowing that until they've keyed in the full 5-digit combination which then gives you the green light to extract your bike.

It's also useful to note that before you get to this point you have to use an unresponsive touchscreen to buy your 24 hours. It's during this procedure that the user's trust in the system begins to wane. It's no wonder therefore that they don't then trust the keypad to register a light-touch press and instead poke away at it with their fingernails. A little beep and a flash of the green or yellow LED would solve this problem.

There were these fingernail marks on every single bike stand I saw. It's a shame because many other parts of the system are beautifully designed.
