1. A method, comprising:
- outputting a display signal configured to display a graphical object on a touch-sensitive input device;
receiving a sensor signal from the touch-sensitive input device, the sensor signal indicating an object contacting the touch-sensitive input device;
determining an interaction between the object contacting the touch-sensitive input device and the graphical object; and
generating an actuator signal based at least in part on the interaction and haptic effect data in a lookup table.

Abstract
Systems and methods for providing tactile sensations are disclosed. For example, one disclosed method includes the steps of outputting a display signal configured to display a graphical object on a touch-sensitive input device; receiving a sensor signal from the touch-sensitive input device, the sensor signal indicating an object contacting the touch-sensitive input device; determining an interaction between the object contacting the touch-sensitive input device and the graphical object; and generating an actuator signal based at least in part on the interaction.

12. A system, comprising:
-
a touch sensitive input device configured to output a sensor signal indicating an object contacting the touch-sensitive input device; an actuator coupled to the touch-sensitive input device, the actuator configured to receive an actuator signal and output a haptic effect to the touch-sensitive surface basted at least in part on the actuator signal; and a processor in communication with the sensor and the actuator, the processor configured to; output a display signal configured to display a graphical object on the touch-sensitive input device; receive the sensor signal from the touch-sensitive input device; determine an interaction between the object contacting the touch-sensitive surface and the graphical object; generate the actuator signal based at least in part on the interaction and haptic effect data in a lookup table; and transmit the actuator signal to the actuator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
