  • Publication number: 20100017759
    Abstract: Systems and methods for physics-based tactile messaging are disclosed. For example, one disclosed method includes the steps of receiving a sensor signal from a sensor configured to sense a physical interaction with a messaging device; determining an interaction between one or more virtual message objects and a virtual message environment, the interaction based at least in part on the sensor signal and a virtual physical parameter of at least one of the one or more virtual message objects; and determining a haptic effect based at least in part on the interaction. The method additionally includes the step of generating a haptic signal configured to cause an actuator to output the haptic effect.

  • Publication number: 20100013761
    Abstract: Systems and methods for shifting haptic feedback function between passive and active modes are disclosed. For example, one disclosed method includes receiving a first signal from a sensor, the first signal associated with a mode of interaction with a graphical user interface; receiving a second signal associated with an interaction with the graphical user interface; determining a haptic feedback effect based at least in part on the mode of interaction with the graphical user interface and the interaction with the graphical user interface; and generating a haptic signal configured to output the haptic feedback effect.
