| 20100173686 | Programmable Game-Based Haptic Enabled Gun Controller - Various systems, game controllers, and methods for simulating various objects such as weapons are provided. For example, a game controller may include a trigger, a processor within the body that receives a trigger signal when the trigger is activated by the user. The processor may communicate with a computer running a software program such as a gaming application, and an actuator coupled to the trigger, the actuator configured to output a haptic effect to the trigger in response to receiving a control signal from the processor. The game controller may simulate a gun and generate a recoil effect. In some embodiments, the recoil effect may be generated by impacting a moving mass from a discharge end of the gun to a handle end of the gun. In some embodiments, the recoil effect may be generated by using a body part of a user as a tether. | 07-08-2010 |
| 20100231539 | Systems and Methods for Interfaces Featuring Surface-Based Haptic Effects - Systems and methods for interfaces featuring surface-based haptic effects are described. One described system includes a sensor configured to detect a touch in a touch area when an object contacts a touch surface. The touch surface may correspond to the display area or may correspond to a non-display surface of a computing device or peripheral interfaced to a computing device. The system can further include an actuator in communication with the processor and coupled to the touch surface, the actuator configured to output a haptic effect and a processor configured to select a haptic effect to generate. The haptic effect can be selected based on a position of the touch and recognizing an input gesture provided by the touch and/or content displayed in a graphical user interface at a location mapped to a position in the touch area at or near the touch. The haptic effect may provide a texture, simulate an obstacle, and/or adjust the coefficient of friction of the surface. | 09-16-2010 |
| 20100231541 | Systems and Methods for Using Textures in Graphical User Interface Widgets - Systems and methods for using textures in graphical user interface widgets are disclosed.
