High definition haptic effects generation using primitives

Abstract

A haptically enabled system is provided. The system receives a haptic effect primitive including a plurality of input parameters that define a haptic effect. The system also receives an input from a sensor that varies over a time duration. The system generates a dynamic haptic effect signal based on the haptic effect primitive and the input, which includes generating a plurality of output parameters including an amplitude of the dynamic haptic effect signal, and varying the amplitude of the dynamic haptic effect signal continuously over the time duration using frequency modulation. The system then applies the dynamic haptic effect signal to an actuator to generate the haptic effect.

What is claimed is: 
     
         1 . A method of generating haptic effects on a device, the method comprising:
 receiving a haptic effect primitive including a plurality of input haptic parameters that define a haptic effect;   receiving an input, from a sensor, that varies over a time duration;   generating a dynamic haptic effect signal based on the haptic effect primitive and the input, including:
 generating a plurality of output haptic parameters including an amplitude of the dynamic haptic effect signal, and 
 varying the amplitude of the dynamic haptic effect signal continuously over the time duration using frequency modulation, the amplitude of the dynamic haptic effect signal being a function of at least a carrier signal amplitude (a c ), a modulation signal amplitude (a m ), a carrier signal frequency (f c ) and a modulation signal frequency (f m ); and 
   applying the dynamic haptic effect signal to an actuator to generate the haptic effect.
