Automotive - vibrating alert, touch screen

A major drawback of touch controls is the lack of tactile feedback. This can lead to the driver taking their eyes off the road to see if their input was accepted.

Personal electronics
By adding haptic effects, the personal electronics manufacturers can offer their product with tactile feedback rather than just audible feedback.
