Abstract: A method, a feedback-enabled device and a computer-readable memory are provided, for generating haptic feedback. The actuators of a tactile surface are vibrated for producing vibration bursts based on a sequence of an adaptive friction grain signal. The adaptive friction grain signal comprises a plurality of grains corresponding to the vibration bursts, each grain being defined by an amplitude. The adaptive friction grain signal has a grain density that is variable over the sequence.
