driver interfaces

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."

Ask anyone who's ever talked back to their GPS navigation system: Product developers are pretty good at using technology to humanize inanimate objects. But how would you like it if your car responded to your presence -- lighting up with delight or panting like a pet dog? What if, more helpfully, it recognized your touch on the steering wheel, and queued up your favorite MP3s and set your seating position just the way you liked it?
