How effortlessly abstracted are you? Perhaps more than you imagine. And rapidly you'll be capable to enumerate your distractibility, with a wearable head tracker being built by engineers in Australia.
Julien Epps from the University of New South Wales has inventd a tracker that straps onto a baseball cap and monitors head actions. From the data it gathers, it can work out a task's strength and when someone switches from one job to a further.
It works because people lean to move their heads more through easy tasks, and fewer through intricate ones. During tests on twenty students who were performing problems, the sensor could notify with 70%-80% precision how difficult the sums were.
If built into devices like Google Glass, such a sensor could be used to minimize disruptions while you're working, and tell you when it's occasion to get a break. It could also create perilous tasks securer if it notices that someone isn't focussed.
"Computing devices are with us all the time. Our smartphones are on our person. I think they need to be able to understand what we're doing in order to interrupt us at the right time," Epps told New Scientist. His system has been comprehensive in a document in the Proceedings of the 37th Annual International Conference of the IEEE.
