Idea: Tactile Feedback While Driving
Car companies are coming up with new ways of making sure you’re aware of other cars in your blind spots. Using radar and special mirrors, you will soon get audible and visual warnings when cars are approaching.
But what about tactile feedback? When I drive, my hands are already on the steering wheel, so why not take advantage of that to let me feel when a car is approaching in my blind spot?
The steering wheel could be embedded with a row of nubs that protrude under your hands when they need to alert you to another car’s presence. If a car is approaching in your blind spot on the right, the nubs raise under your right hand letting you feel the car’s presence. Likewise for the left side. And the wheel could detect where you place your hands while you drive, so if you don’t keep your hands at ten and two the nubs will be active wherever you do place your hands.
With practice, it could become second nature to use the sense of touch to gather information while you drive, just like you use sight and sound already.
