Systems and methods for adaptively interpreting a user's intent based on parameters supplied by a touch-sensitive input device are described. In one of the methods described, a processor is programmed for receiving contact data from an input device; determining whether to output a haptic effect based on the contact data; and outputting the haptic effect based on the contact data.

Systems and methods for adaptive interpretation of input from a touch-sensitive input device

Systems and methods for adaptively interpreting a user's intent based on parameters supplied by a touch-sensitive input device are described. In one of the methods described, a processor receives a pressure signal indicating a pressure from an input device, such as a touchpad, compares the pseudo pressure signal to a pressure threshold value, and outputs a signal if the pseudo pressure signal is greater than the pressure threshold value. In another embodiment, the processor also calculates the speed of movement of a conductor, for instance a user's finger, across the input device, and compares the speed to a threshold. If the speed is greater than the threshold, the processor determines that although the pressure may be great enough to signal a press, no press is intended. The various parameters supplied by the input device may be digitally filtered to increase the accuracy of the determination of user intent.

Systems and methods for providing haptic feedback in a user interface are disclosed. In one embodiment, an apparatus comprises a manipulandum, a rotor in communication with the manipulandum, an actuator in communication with the rotor, and a biasing element disposed between the manipulandum and the rotor. The actuator may be configured to vary a force on the rotor. The biasing element may be configured to store at least a portion of energy input to the apparatus when the actuator increases the force on the rotor, and to provide at least a portion of the stored energy to the manipulandum when the actuator decreases the force on the rotor, or when the manipulandum is released.

Systems and methods for providing a haptic device

Systems and methods for providing visual navigation cues in user interfaces for use with rotary input devices are described. One described method comprises causing a plurality of graphical objects to be displayed in an arc. The curvature of the arc is configured to convey the ordinal relationship for navigating between each of the plurality of graphical objects with a rotary input device. The curvature of the arc is independent of the spatial relationship between the rotary input device and a display.
