On invasive technologies.
“HCI practitioners are increasingly interested in designing interactive technologies to support the body. At the CHI conference, research around health in particular has grown over the past decade. Once consisting of a session or two on health-related papers, it has since become one of the largest dedicated tracks in the conference. That said, few of us in HCI are experts in how the body works as a complex suite of physiological, interacting systems. Understandably so: Such expertise takes years of study in, for example, body-oriented fields like medicine or sports science. It is not a huge stretch, however, to expect that having more expertise about the body’s complex systems would enable us to design better tools. For example, a screwdriver can be effective for working on some parts of a car, but if we wish to ensure that the engine under the hood is running well, we need additional, specific tools like timing lights and spark-gap slides. Understanding how to use these tools, of course, is an essential requirement for ensuring the optimal performance of that machine.”
