As we create our digital lives—communicating and socializing with others, collecting content for business and pleasure, building objects with software, buying products—we understand that, despite its moniker, this existence is only half virtual. While it’s a given that engaging in our digital experiences requires physical devices, it may be less obvious that the input method affects the way in which we communicate with our computers—particularly, the way we feel about the experience.
In the physical world, we don’t have to think about manipulating an object—we just do it. Turn a photograph around on a table? Pick it up to take a closer look? Put it into a file folder? All of these are purely automatic actions.
