    • Pointing devices and related methods are disclosed that generally involve manipulation of a cursor or other user interface component based on inputs from a user. In one embodiment, an image sensor captures an image of the underside of a transparent contact surface and determines whether an object (e.g., a user's finger) is present in the image. Cursor movement information comprising direction and velocity components can be calculated from a single image by equating the size of a detected object with a desired velocity and by equating the position of the detected object relative to a fixed reference point with a desired direction. Thus, detection of user motion is not required, nor is comparison of successive image frames relative to a time reference. As a result, a device having few or no moving parts can be provided while at the same time permitting continuous cursor motion without repetitive swiping by a user.
    • 指出设备和相关方法通常包括基于来自用户的输入来操纵光标或其他用户界面组件。 在一个实施例中,图像传感器捕获透明接触表面的下侧的图像,并且确定图像中是否存在物体(例如,用户的手指)。 包括方向和速度分量的光标移动信息可以通过将检测到的对象的大小与所需速度相等并且通过将检测对象相对于固定参考点的位置与期望方向相等来从单个图像计算。 因此,不需要检测用户运动,也不需要相对于时间参考的连续图像帧的比较。 结果,可以提供具有很少或不具有移动部件的装置,同时允许连续的光标运动而不会由用户重复滑动。
