In 2014, publisher and technology guru Tim O’Reilly gave a speech entitled “Software Above the Level of an Individual Device.” In it, he described the foundational pattern that IoT enables: instead of individual computers, we’re building a network of devices that “make it possible to completely rethink how we organize work, play and society itself.”
Implicit in O’Reilly’s argument is the need for new ways of interfacing with these device networks to unlock their potential: What we need are user experiences that go beyond the level of a single device.
This multi-device experience design is called interusability, and it is central to building successful IoT products.
What is Interusability?
The term “interusability” was coined in 2005 by Charles Denis and Laurent Karsenty. They argued that conventional UX design was ill-equipped to handle multi-device interfaces. The discussion continued in 2010 when a group of researchers published a practical framework for interusability. In 2015, O’Reilly Media launched Designing Connected Products, which we at SpinDance consider the current definitive work on the subject.
If you don’t have time for articles or books, Claire Rowland’s 49 slide presentation on the subject is worth checking out. In particular, this chart is a good guide for thinking about where interusability fits in the larger UX/software world:
So what is interusability?…
