摘要： A low-cost, high-resolution capacitive position sensor is provided using a variable capacitor. A vane moves parallel to a stator, where a dielectric is interposed between vane and stator, such that the vane overlaps at least a portion of the stator, creating a capacitance that varies as the vane moves relative to the fixed stator. The capacitor circuit outputs a signal having a phase shift relative to an input driver signal based on the relative positions of the vane and stator. The phase-shifted signal is used to derive the absolute position of the vane with respect to the stator. Two or more stator can be provided to provide two phase-shifted signals and a difference signal free of common mode effects. Enhanced embodiments include interdigitated stator portions for greater sensing resolution, and/or a two or three-pole filter to double or triple the dynamic range of the sensor.

摘要： Method and apparatus for controlling magnitude and frequency of vibrotactile sensations for haptic feedback devices. A haptic feedback device, such as a gamepad controller, mouse, remote control, etc., includes a housing, an actuator coupled to the housing, and a mass. In some embodiments, the mass can be oscillated by the actuator and a coupling between the actuator and the mass or between the mass and the housing has a variable compliance. Varying the compliance allows vibrotactile sensations having different magnitudes for a given drive signal to be output. In other embodiments, the actuator is a rotary actuator and the mass is an eccentric mass rotatable by the actuator about an axis of rotation. The eccentric mass has an eccentricity that can be varied relative to the axis of rotation while the mass is rotating. Varying the eccentricity allows vibrotactile sensations having different magnitudes for a given drive signal.

摘要： An interface device providing haptic feedback to a user is in communication with a host computer. The device includes a housing, at least one sensor for detecting user input, and an actuator assembly. The actuator assembly includes a grounded flexure suspension coupled to an inertial mass which moves when the actuator assembly is energized to cause inertial sensations. The inertial mass includes a pole piece surrounding a magnet, and a grounded coil between magnet and pole piece causes the motion of the inertial mass when current is flowed therethrough. Another embodiment provides directional haptic feedback to a user and includes at least two actuator assemblies oriented such that the inertial masses oscillate substantially orthogonally, and can be controlled to output the inertial sensations approximately along a single axis having a desired orientation.

摘要： A haptic feedback control device, such as a handheld remote control or handheld game controller, for controlling a graphical object within a graphical display and for outputting forces to a user. A housing includes a button, wherein the user engages the button with a finger. The button is depressible along a degree of freedom by the user. An actuator applies forces to the user through the button along the degree of freedom. A sensor detects displacement of the button along the degree of freedom when the button is depressed by the user. A process, local to the device, controls the actuator to generate the forces upon the button in the degree of freedom to provide a tactile sensation to the user contacting the button.
