    • 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.
    • 用于控制触觉反馈装置的振动触觉感觉的幅度和频率的方法和装置。 诸如游戏手柄控制器,鼠标,遥控器等的触觉反馈装置包括壳体,联接到壳体的致动器和质量块。 在一些实施例中,质量可以由致动器振荡,并且致动器和质量块之间或者质量块和壳体之间的联接具有可变的顺应性。 改变合规性允许输出给定的驱动信号具有不同幅度的振动触觉。 在其他实施例中,致动器是旋转致动器,并且质量块是由致动器围绕旋转轴线旋转的偏心质量块。 偏心质量具有在质量旋转时可相对于旋转轴线变化的偏心度。 改变偏心度使给定驱动信号具有不同幅度的振动触觉。

    • Method and apparatus for compensating for position slip in interface devices that may occur between a manipulandum and a sensor of the device due to a mechanical transmission. A device position delta is determined from a sensed position of a manipulandum of an interface device. It is determined if position slip has occurred caused by a change in position of the manipulandum that was not sensed by a sensor of the interface device, typically caused by a mechanical transmission between sensor and manipulandum. If position slip has occurred, an error in the sensed position caused by the position slip is corrected by adjusting the sensed position to take into account the position slip. The adjusted position delta is used as the position of the manipulandum and the display of objects controlled by the interface device are accordingly compensated.
    • 用于补偿由于机械传动而可能发生在装置的操纵和传感器之间的界面装置中的位置滑移的方法和装置。 从接口设备的操作的感测位置确定设备位置增量。 通过由传感器和操纵之间的机械传动引起的接口装置的传感器没有感测到的操作位置的变化,确定是否发生位置滑移。 如果发生位置滑移,则通过调整感测位置来考虑位置滑移来校正由位置滑移引起的感测位置的误差。 调整后的位置增量被用作操纵的位置,相应地补偿由接口装置控制的物体的显示。

    • A mechanism for providing selective engagement of spring members to a user manipulatable object in a force feedback interface device. A moveable member included in a force feedback mechanism is moveable in a degree of freedom to transmit forces to the user manipulatable object, such as a joystick handle. A spring member can be selectively coupled and decoupled between a grounded member and the moveable member. The spring member provides a spring force on the moveable member that biases the joystick handle to a desired position, such as the center of the degree of freedom. A dynamic calibration procedure reduces inaccuracies when sensing the position of the user manipulandum by only reading new range limits when the actuator is not outputting a force in the direction of that limit. A capstan drive mechanism is preferably coupled between the actuator and linkage mechanism, where a capstan drum includes a curved end over which the cable is routed, the curved end including flanges to substantially prevent the cable from slipping of the sides of the end. The capstan drum includes a tensioning spring member coupled to one or both ends of the cable for tensioning the cable.
    • 一种用于在力反馈接口装置中提供弹性构件到用户可操纵物体的选择性接合的机构。 包括在力反馈机构中的可移动构件可在自由度上移动以将力传递到用户可操纵的对象,诸如操纵杆手柄。 可以在接地构件和可移动构件之间选择性地联接和分离弹簧构件。 弹簧构件在可移动构件上提供弹簧力,其将操纵杆手柄偏压到期望的位置,例如自由度的中心。 当致动器不在该极限方向上输出力时,动态校准程序通过仅读取新的范围限制来感测用户操纵的位置来减少不准确度。 绞盘驱动机构优选地联接在致动器和联动机构之间,其中主导轮鼓包括弯曲端,电缆在该弯曲端上被路由,弯曲端包括凸缘,以基本上防止电缆滑动端部的侧面。 绞盘鼓包括联接到电缆的一端或两端的张紧弹簧构件,用于张紧电缆。
