Vibrational feedback comes from Kickback, the haptic accessibility application. Most users consider it an important part of their Eyes-Free experience.
What Kickback Does
Kickback emits short vibrational bursts when the navigational control moves focus to a new item, when buttons on the touch screen are pressed, when controls are activated using the physical keyboard, when the state of a checkbox changes, and often when the screen refreshes. This is very helpful as it can provide feedback when speech isn't available. For example, when users are arrowing around a screen that is fully or partially inaccessible, it signals that focus is on a new icon, and when users must activate buttons on the touch screen by dead reckoning, it lets them know they've successfully found the soft control.

To turn on Kickback, do the following:1. Unlock the screen if necessary.
