1. A method of producing a haptic effect comprising:

  • receiving a video having a plurality of frames;

    determining a partial area of a video frame;

    detecting an abrupt camera movement, comprising;

    determining an optical flow estimate of one or more stationary objects within the partial area between a first frame and a second frame, the second frame subsequent to the first frame;

    detecting an apparent abrupt movement of the one or more stationary objects within the partial area between the first frame and the second frame based at least in part on the optical flow estimate and a magnitude threshold;

    determining the abrupt camera movement based on the apparent abrupt movement of the one or more stationary objects;

    generating a haptic effect corresponding to the abrupt camera movement; and

    producing the haptic effect via a haptic output device.
