Instead of thinking about the buttons on a phone or a laptop, manufacturers and designers need to think about what will happen when computers are embedded in everything and connected all the time. Instead of computing confined in a box on a desk or in the hand, computers will be everywhere pulling data from a variety of places. Understanding how those computers will pull information about their environment, relay that data to users and then interpret what users want them to do creates a web of interaction that will require new ways of thinking and design.

In fact, user interaction might be a very minimal part of the overall design. For example, Rolston described a wearable glucose monitor that has elements embedded in the body, a monitor interpreting the data from the user’s bloodstream and a wearable screen for the patient to interact with. Of those three elements the patient input screen is likely gathering the least important information and must convey complicated information simply.

In a conversation after his panel, Rolston explained the challenges inherent in designing interfaces in such a world will come from devices trying to understand a user’s intent, as we build out new ways to interact with them, such as motion. How will a machine know when someone waving their hands while they talk to a friend becomes someone trying to tell a computer to do something? Of course, when a device can watch us and interpret our movements and commands effectively it essentially gives computers the illusion of humanity. That’s the illusion Rolston apparently is trying to create.
