Building Facebook Home with Quartz Composer (by David O Brien)
This is just the first in a series of videos that Dave O Brien created in a timely fashion: Some of you may have heard about the Facebook design team using Quartz Composer for prototyping their Home app.
The emphasis on animations resonates with another current debate, about the haptic experience that physical books provide. The result of that haptic experience should not come as a surprise to you, my endeared regular readers: There are affordances about mapping information to spatial and haptic cues that pictures under glass can’t provide.
When you read a book or magazine, you are navigating information in physical space. Your brain creates a rough map of the information that you are browsing while you are flipping page after page. Moreover, it draws upon past experiences with book space to inform the mental image of your current read and bestows you with a sense of empowerment over the text, and a feeling of serendipity.
Now, when you take away the physical feedback that paper provides to your senses, you are taking away functionality from the user interaction with the text. No feeling the weight of pages to tell how far into the text you are, no sense of halting and reversing the flick of a page in mid-air because you glanced something you want to inspect more closely.
But you know what pictures under glass can do for you to give you some design elements not available to print? That’s right. Animation. Hence the video above. The design team from Facebook realized just how much physicality matters, so they looked for a way to make their wireframes animate according to physics. Inertia, pseudo-gravity, all these sorts of things matter in animation.
I’m not saying that you can fully emulate the experience of physical objects with current digital technology. I’m saying that you need to make up for the shortcomings of our current interaction paradigm (pictures under glass) by introducing explicit feedback mechanisms. Visual feedback is the go-to choice most of the time. But sound or vibration is already available in many touch devices.
