Which is More Confusing: Initial Wayfinding or Wayfinding Revisited?

Which do you find more confusing: going to a place you’ve never visited before or going to a place you once knew well, but that has changed significantly? In an opinion piece in The New York Times, “London Lost and Found,” Mahesh Rao describes his literal and figurative confusion as he revisits London once or twice a year after he moved from there to India in 2008. As a visitor he looks more intently and sees small sights he missed when he was a resident. Rather than taking things for...

Sharks Find Their Way Using Smell

Scientists are closer to solving one of the mysteries of how living creatures who can’t rely on GPS and wayfinding skills (unlike you, dear reader) find their way around. Take sharks, for example. Experts knew that sharks are guided by the earth’s magnetic field as they move in the ocean, but were curious about other factors, including smell, that might also influence navigation. A team of five investigators tracked leopard sharks, “a Pacific coastal species that makes foraging trips out...

A Mapmaker for Self-Driving Cars

If you’re directionally challenged, you may have dreamed of never having to navigate again as your car finds its way by itself. That day is edging ever closer as self-driving (autonomous) cars are being developed and tested. John Ristevski, of HERE, a global company that builds high-resolution maps, is one of the people who may make it possible for you (and your autonomous car) to navigate under normal conditions and even in a blizzard, when you can’t see the road in front of you. He and...

Who Navigates More Effectively: Men or Women? (Part 2 of 2)

In the study referenced in the previous blog post (Who Navigates More Effectively: Men or Women? (Part 1 of 2)), medical doctor and PhD candidate, Carl Pintzka, at the Norwegian University of Science and Technology in Trondheim used an MRI scanner to monitor brain activity when 18 men and 18 women used 3D goggles and a joystick to orient themselves in a large virtual maze. He found that men were more effective and, in a followup study, when women were given a single drop of the male hormone,...

Who Navigates More Effectively: Men or Women? (Part 1 of 2)

The 2015 wayfinding story that grabbed the most attention pertains to that old battle of the sexes (often taking place in the front seats of cars): who has the better sense of direction: men or women? Spoiler alert: in one Norwegian study, men did better at finding their way quickly in a virtual environment. The study was conducted by medical doctor and PhD candidate, Carl Pintzka, at the Norwegian University of Science and Technology in Trondheim. He used an MRI scanner to monitor brain...
