Remember when mom tugged you toward home by the earlobe when you were bad? That's the concept behind this GPS navigation helmet
And you thought that lady from your car's navigation system was stern. Human-machine interface Researchers from Kajimoto Laboratory came up with this GPS navigation helmet that doesn't give directions in words, it "shows" the wearer which way to go by tugging on the appropriate ear, just like mom used to do. "Being pulled on the ear for navigation is a common situation when we were children," researchers write, "and hence, the sensation should be quite intuitive."
