1. An interface device for providing directional haptic feedback, the interface device comprising:

  • a housing;

    at least one sensor configured to detect input on the interface device;

    a signal generator configured to divide a current of a control signal between a first harmonic actuator signal and a second harmonic actuator signal based on a predetermined ratio of a first magnitude of the first harmonic actuator signal to a second magnitude of the second harmonic actuator signal;

    a first actuator assembly coupled to the housing, the first actuator assembly including a first mass and configured to receive the first harmonic actuator signal; and

    a second actuator assembly coupled to the housing, the second actuator assembly including a second mass and configured to receive the second harmonic actuator signal,first actuator assembly and the second actuator assembly are positioned in the housing, and the first harmonic actuator signal and the second harmonic actuator signal are configured to cause a haptic effect at a location between the first actuator assembly and the second actuator assembly, the location based on the predetermined ratio.
