Abstract
Implementations include methods of controlling a haptic response comprising receiving a force signal from a force sensor; determining a force magnitude associated with the force signal; comparing the force magnitude with an initial threshold force amount to determine whether the force magnitude exceeds the initial threshold force amount; measuring an elapsed time that the force magnitude exceeds the initial threshold force amount; comparing the elapsed time to a minimum elapsed time; if the elapsed time being greater than the minimum elapsed time, generating a haptic feedback control signal, the haptic feedback control signal causing a haptic actuator to propagate a plurality of pressure waves at a propagation frequency, the propagation frequency being proportional to the force magnitude; and generating a scroll control signal that causes a menu system to scroll through a plurality of menu options provided by the menu system at a scroll frequency associated with the propagation frequency.
