    • A method and apparatus for controlling and providing force feedback using an interface device manipulated by a user. A microprocessor is provided local to the interface device and reads sensor data from sensors that describes the position and/or other information about a user object moved by the user, such as a joystick. The microprocessor controls actuators to provide forces on the user object and provides the sensor data to a host computer that is coupled to the interface device. The host computer sends high level host commands to the local microprocessor, and the microprocessor independently implements a local reflex process based on the high level command to provide force values to the actuators using sensor data and other parameters. A provided host command protocol includes a variety of different types of host commands and associated command parameters. By providing a relatively small set of high level host commands and parameters which are translated into a panoply of forces, the protocol further shifts the computational burden from the host computer to the local microprocessor and allows a software developer to easily create force feedback applications.
    • 一种使用由用户操纵的接口装置来控制和提供力反馈的方法和装置。 在接口设备本地提供微处理器,并从传感器读取传感器数据,该传感器描述用户(例如操纵杆)移动的用户对象的位置和/或其他信息。 微处理器控制致动器以在用户对象上提供力并将传感器数据提供给耦合到接口设备的主计算机。 主计算机向本地微处理器发送高电平主机命令,并且微处理器基于高电平命令独立地实现局部反射过程,以使用传感器数据和其他参数向致动器提供力值。 提供的主机命令协议包括各种不同类型的主机命令和相关的命令参数。 通过提供一组相对较小的高级主机命令和参数,这些命令和参数被翻译成一个总体的力量,协议进一步将计算负担从主机转移到本地微处理器,并允许软件开发人员轻松创建力反馈应用程序。

    • Method and apparatus for providing thermal protection for actuators used in haptic feedback interface devices. An average energy in the actuator over a predetermined period of time is determined, and the maximum allowable current level in the actuator is reduced if the average energy is determined to exceed a predetermined warning energy level. The maximum allowable current level can be reduced to a sustainable current level if the average energy reaches a maximum energy level allowed, and the maximum allowable current level in the actuator can be raised if the average energy is determined to be below the predetermined warning energy level. Preferably, the maximum allowable current level is reduced smoothly as a ramp function.
    • 用于为触觉反馈接口装置中使用的致动器提供热保护的方法和装置。 确定在预定时间段内的致动器中的平均能量,并且如果确定平均能量超过预定警告能级,则致动器中的最大允许电流水平降低。 如果平均能量达到允许的最大能量水平,则最大允许电流水平可以降低到可持续的电流水平,并且如果平均能量被确定为低于预定的警告能量水平,则可以提高致动器中的最大允许电流水平 。 优选地,最大允许电流水平作为斜坡功能平滑地减小。

    • A method and apparatus for shaping force signals for a force feedback device. A source wave is provided and is defined by a set of control parameters (including a steady state magnitude, a frequency value and a duration value) and modified by a set of impulse parameters (including an impulse magnitude, and a settle time representing a time required for the impulse magnitude to change to the steady-state magnitude). Optionally, application parameters specifying a direction of force signal and trigger parameters specifying activating buttons can also be provided for the source wave. Using a host processor or a local processor, the force signal is formed from the source wave and the sets of control parameters and impulse parameters, where the force signal includes an impulse signal followed by a continual steady-state signal after an expiration of the settle time. A feel sensation is generated to a user of the force feedback device as physical forces produced by actuators on the force feedback device in response to the force signal. The steady-state magnitude value is lower than a magnitude value of a non-impulse-shaped force signal required to create a corresponding feel sensation having a similar apparent sensation to the user.
