Sports science is becoming increasingly sophisticated. AtSeattle Sounders FC, (an MLS team) David Tenney the team’s fitness coach explains how its use of wearable technology, GPS data and data from triangulated video shoots are used to build fitness profiles that are visualized in Tableau and then used to optimize training and fitness plans for the star players.
“Imagine a digital tattoo that transmits skin temperature; a transparent sensor on a contact lens that tests for glaucoma; a pliable pacemaker wrapped around a beating heart; and an implant that controls pain after surgery, then dissolves harmlessly when it is no longer needed.
Each one is an experiment under way today in the biophysics of personal medicine.
At laboratories in the U.S., Switzerland, and Korea, bioengineers are developing unusually flexible ultrathin electronics that promise to free medical diagnostics from the clinical tethers of cables and power cords, to make measuring vital signs more intimate and effective.”

“The variability is astounding. We have an office of 30 to 35 people, and with a simple measurement like the circumference of the wrist, we have a variability of 100 percent. The largest wrist is twice as large as the smallest wrist. The other element which is very difficult is that the technology pieces are still quite cumbersome. Batteries come in boxy shapes, screens come with sharp corners. Wielding these elements is an art.”
A "cognitive activity tracker" developed by Kai Kunze at Osaka Prefecture University in Japan can tell how many words we read, how often and how fast we read, and even whether we are skim reading or actually concentrating on the content. It could also generate summaries of documents as you read them by logging which passages your eyes dwell on.
Such detail about what we look at, whether on a screen or on paper, is being made possible by the emergence of gaze-trackers – devices that monitor our eyes to analyse where we are looking. Swedish firm Tobii Technology is leading the way in commercialising the technology. It has developed a $99 system that uses infrared cameras trained on the cornea to watch for the eyeball's movements. These cameras can be built into a headset, such as Google Glass, or clipped to the top of a computer screen or tablet.
The point isn't the gadget: it's the combination of the intimacy of a device that is always with us and that only we use, with the power of cloud-based processing and storage. The wearable device itself is actually only the small, physical manifestation of a much larger service: Google Glass gives its wearers a head-up display, voice control and a forward-facing camera, but it's only through a connection to the internet that it can live up to its potential.
“The neurocam is the world's first wearable camera system that automatically records what interests you.
It consists of a headset with a brain-wave sensor and connects to an iPhone. The system estimates whether you're interested in something from the brain-waves captured by the sensor, and uses the iPhone's camera to record the scenes that appear to interest you.”
