    • A low-cost haptic feedback trackball device for providing haptic feedback to a user for enhancing interactions in a graphical environment provided by a computer. The trackball device includes a sensor device that detects the movement of a sphere in two rotary degrees of freedom. An actuator applies a force preferably along a z-axis perpendicular to the plane of the surface supporting the device, where the force is transmitted through the housing to the user. The output force is correlated with interaction of a controlled graphical object, such as a cursor, with other graphical objects in the displayed graphical environment. Preferably, at least one compliant element is provided between a portion of the housing contacted by the user and the support surface, where the compliant element amplifies the force output from the actuator by allowing the contacted portion of the housing to move with respect to the support surface. The force can be an inertial force, contact force, or a combination of forces that provide tactile sensations to the user.
    • 一种低成本触觉反馈轨迹球装置,用于向用户提供触觉反馈以增强由计算机提供的图形环境中的交互。 轨迹球装置包括传感器装置,其以两个旋转自由度检测球体的运动。 执行机构优选沿着垂直于支撑该装置的表面的平面的z轴施加力,其中力通过壳体传递给使用者。 输出力与受控图形对象(如光标)与显示的图形环境中的其他图形对象的交互相关。 优选地,至少一个顺应元件设置在与使用者接触的壳体的一部分与支撑表面之间,其中柔性元件通过允许壳体的接触部分相对于支撑件移动而放大来自致动器的力 表面。 力可以是向用户提供触觉的惯性力,接触力或力的组合。
