Sophisticated Haptic Drivers for PWM Signals

October 16, 2013 3:35 pm | by Duane Sorlie, Senior Staff Engineer, Fairchild Semiconductor | Articles | Comments

Tactile feedback, often referred to as simple “haptics,” uses the sense of touch in a user interface design to provide information to an end user. This generally means the use of the system’s vibration alert system to denote that a button has been pressed. The resistive force that some “force feedback” joysticks and video game steering wheels provide is a form of haptic feedback.
