Resumability is not a word, but it’s an important concept to me.
When I say Resumability, I’m talking about the ability to quickly interrupt and later resume a task.
The task doesn’t have to be productive. The greatest resumable device I’ve ever owned is the Nintendo DS.
The DS was a clamshell-shaped portable gaming system. If you needed to stop playing, you could just slam the case shut (with a satisfying clunk sound).
Two hours (or two days) later, you could flip open the DS and you were immediately exactly where you left off. You could just un-pause and keep playing as though no time had passed.
There was no boot up, no menus to navigate, no agreements to confirm. You just keep playing.
When you’re a tired parent without much time for video games, resumability is key. If it’s going to take me two or three minutes to get into the game, I may have just used up half of the time I had available in the first place.
Other devices that are good at resumability:
- Most dedicated e-reader devices like the Kindle or Kobo resume exactly where you left off.
- Modern smart phones: Press an Off button, slide it in your pocket, take it out later and unlock it with your fingerprint or face, and you are exactly where you left off (feeding your dopamine addiction at the cost of your relationships and connection to society)
- Slack, the work chat app, is resumable even across devices. If I’m in the middle of typing a long message and my laptop flies out of my hands into the ocean, I can pick up where I left off from my phone.
Sometimes resumability needs to be designed into a device, like the examples above. For some types of devices, they are resumable by their very nature. A book with a bookmark is always ready to go. When you pressed STOP on an old audio cassette player, it just sat there in a physical arrangement ready to resume exactly where you left off a year later.
We don’t always want such a friction-less experience though. Friction is safe. It keeps you from falling down. Friction in an entertainment device, can also help keep you from excessive unwanted distraction.
If my TV takes 20 seconds to boot up, that might be just enough friction to keep me walking past it rather than getting sucked into watching something I don’t even really want to see.
Just don’t make me wait 3 seconds to resume my New Super Mario Bros. game.
