  • HAPTIC FEEDBACK SYSTEMS AND METHODS
    Publication number: 20140125471
    Abstract: A haptic feedback device can include a surface magnet and a first electromagnet sufficient to cause the physical movement of the surface magnet along a first axis. One or more individually addressable pin driver circuits may be communicably coupled to the electromagnet. The individually addressable pin driver circuit is selectively switchable into a number of operating modes that includes a current sourcing mode, a current sinking mode, and an impulse mode. A controller is communicably coupled to each of the pin driver circuits via a digital bus. The controller selects an operating mode and one or more parameters for each of the individually addressable pin driver circuits.
