    This makes me think of my Mom and her struggle with migranes. She would benefit from a simple iOS app that helps her track symptoms & potential triggers in a way that could easily be shared with her doctor.

  • The world goes dark for about one-fifth of a second every time you blink, a fraction of an instant that’s hardly noticeable to most people. But for a Formula One race car driver traveling up to 354 kilometers per hour, that one-fifth means almost 20 meters of lost vision
  • People are often thought to blink at random intervals, but researchers found that wasn’t the case for three Formula drivers.
  • the drivers tended to blink at the same parts of the course during each lap, cognitive neuroscientist Ryota Nishizono and colleagues report in the May 19 iScience

      Interesting. So, do we do the same thing while driving around town? Could you design a method to record eye blinks as people drive known routes around town? We could simultaneously use the Arduino Science Journal app on the iPhone to also correlate physical data in a moving car like acceleration/deceleration, motion in X, Y, Z directions, etc. I wonder if we could find a correlation in everyday driving that could help from a safety perspective?

  • He was surprised to find almost no literature on blinking behavior in active humans even though under extreme conditions like motor racing or cycling

      OK, now this SCREAMS: "potential research idea."
  • Nishizono and colleagues mounted eye trackers on the helmets of three drivers and had them drive three Formula circuits
  • Where the drivers blinked was surprisingly predictable, the team found. The drivers had a shared pattern of blinking that had a strong connection with acceleration, such that drivers tended not to blink while changing speed or direction — like while on a curve in the track — but did blink while on relatively safer straightaways.

      What sort of implications does this have for driving in key, known, busy interchanges in KC? Could we potentially provide data to show certain stretches of highway need more signage, etc? That could have civil engineering implications.
  • “We think of blinking as this nothing behavior,” he says, “but it’s not just wiping the eyes. Blinking is a part of our visual system.”
  • Nishizono next wants to explore what processes in the brain allow or inhibit blinking in a given moment, he says, and is also interested in how blinking behavior varies among the general population.

      While the "brain" part might move beyond our feasibility, the potential of finding real correlations to driving patterns or routes is a completely different spin-off and one that could have really practical suggestive applications for city planners, etc.
