Why does pull-to-refresh occur, and why isn't pull-down-to-refresh before pull-down-to-refresh occurs? The answers to these questions seem obvious, but they always raise more questions; pursuing them seems to bring us closer to the truth, yet always convinces that all analysis is an overinterpretation.
Similar designs include slide-to-unlock and b2b data pinch-to-zoom. I classify these as designing a behavior.
to design behavior
"Starting from user needs" is the most commonly used design method. The sentence itself is not wrong, but it can be easily misread.
Ordinary people will understand user needs as what users say (“I want a faster horse”), and people with design thinking can understand user needs as the purpose of users’ behavior (“I want to go to the Tangjia market 20 kilometers away to buy.” "Dishes"), very few people are willing to go to the back of the user's needs to see what the 70,000-year-old Homo sapiens species desires from the depths of its genes ("I want survival, food, physiological balance and sex") . I don't think it's a human problem, it's just a methodological limitation. Methodological limitations keep our design activities free between information architecture, usability, and best paradigms. And some good designs, especially when it comes to a new behavior, stop at sticky notes because they don't "best" help the user accomplish a task.
So it's time to add a reminder: "Design for behavior", not just for behavior.
Designing a behavior is different from behavior-centric design, or even at extremes. The latter emphasizes compliance with the "existing" needs of users, while the former tends to create an unprecedented experience for users.
An appropriate behavior can indeed lead to an extraordinary experience with a product, even if it doesn't best help the user accomplish a task.
iOS 10 has a new feature called "raise your wrist to brighten the screen". Pick up your phone from your desk, or pull it out of your pocket, and the screen will automatically light up. In actual experience, you will find that the defect of this function is too obvious. Sometimes you just walk with the phone in your hand, and the screen will light up inexplicably - a very high false-touch rate; and sometimes you really want to see the time, but because you pick up the phone at the wrong angle, it won't light up at all. - Serious frustration during use. Still, you'll have to admit that you can't live without this feature. It's not so-called "Apple magic", it's "behavioral magic." What's more interesting is that after you get used to it, every time you want to check the time or notification, you will subconsciously pick up the phone with the "correct angle" and "correct trajectory".
The Apple Watch also has the function of "lifting the wrist to brighten the screen" (which also has the above defects). Traditional watch wearers look at their watch in a variety of ways, but Apple Watch owners always turn and lift their wrists, even though they can press the crown to light up the screen.
Be aware that if you don't believe in the significance of the design behavior, you may have personally shelved the proposal before the design review.
what behavior is appropriate
Appropriate behavior is often intuitive.
Whenever I talk about intuition, I always think of Naoto Fukasawa's CD player. It's just that I didn't realize so clearly in the past that he was actually designing a behavior.
That CD player has a similar shape to the "exhaust fan". Put the CD in the center, pull the cable, and you can play the CD, which operates like a fan. Even if we know it's a CD player, our bodies react when staring at this CD player because of the image of the exhaust fan. In particular, the skin near the cheeks will "standby" for the wind that is about to blow with a sharper touch. It's just that it's not the wind that blows, it's the music. Due to the shape of the exhaust fan, it may sacrifice its own sound performance a little, but people who listen to music have a sharper feeling, which may also relatively improve the sound performance. - Kenya Hara on MUJI CD players
The most interesting thing about this CD player, I think, is that the person who turns it on personally hears a different kind of music than everyone else.
