摘要： An optical touchpad that may be able to provide accurate, reliable information about the position of an object in three-dimensions. The optical touchpad may enable a determination as to whether the object is engaged with the touchpad or hovering just above the touchpad. When the object is in contact with the optical touchpad, the optical touchpad may enable a determination of the force applied by the object to the optical touchpad. The optical touchpad may enable a determination of an object type of the object. These and other determinations of information related to the object may enhance the control provided by the touchpad system to the user as an electronic interface. The operation of the optical touchpad may further enable an enhanced frame rate, reduced optical noise in the optical signal(s) guided to the one or more sensors, augment the ruggedness of the optical touchpad, an enhanced form factor {e.g., thinner), and/or provide other advantages.

摘要： An optical touch pad that includes a multilayer waveguide optically coupled to at least one electromagnetic radiation detector. Based on electromagnetic radiation directed from an object to the detector by the multilayer waveguide, information related to an object proximate to {e.g., hovering above) and/or in contact with the optical touch pad may be determined. For example, the information related to the object may include position information, object-type information, and/or other information related to the object.

摘要： An optical touchpad system is disclosed that may be easily integrated into a variety of applications. One feature of the optical touchpad system that may contribute to this versatility may be the ability of the optical touchpad system to function in the same manner independent from a topology and/or opacity of an interface surface of the optical touchpad system. This may enable the interface surface to be composed of any of a variety of materials. This may further enable the interface surface to include various topologies adapted for the application in which the optical touchpad system may be employed.

摘要： An optical interface system, such as a touch pad or a touch screen, includes an optical waveguide (P) having a first surface adapted to be engaged by an object in a point-of-touch (O) so as to reflect/scatter radiation into the waveguide (P). The system includes at least one emitter (E1) for injecting radiation into the waveguide (P) and at least one detector (D1, D2) for detecting injected radiation that has been reflected/scattered by the object. The emitter(s) and detector(s) form part of at least one range-finder of the system for determining the distance to the point-of-touch by comparing emitted and detected radiation. The system further includes means (C) for determining the position of the point-of-touch (O) on the waveguide (P). Such determining means (C) may operate on a plurality of distances determined by a plurality of range-finders or on at least one distance determined by a range-finder and a direction/angle for the emitted radiation and/or the detected radiation in a plane parallel to the first surface of the waveguide.

摘要： An interactive display system that may be implemented to provide an electronic whiteboard that enables users to input information to the system by engaging a display with one or more objects. The system may present an image via the display that reflects the inputs received from the user. For example, the display may be dynamically updated to mimic inputs made to a whiteboard by the user via one or more pens and/or an eraser. The interactive display system may implement an underlayer embedded within the display to guide electromagnetic radiation that emanates from an object engaged with the display to one or more detectors by total internal reflection. Due at least in part to the efficiency of the underlayer in guiding the electromagnetic radiation to the detectors, the interactive display system may enhance the speed and/or accuracy of the interpretation of the inputs made by the user.
摘要翻译：一种交互式显示系统，其可被实现为提供电子白板，其使用户能够通过将显示器与一个或多个对象接合来向系统输入信息。系统可以经由显示器呈现反映从用户接收的输入的图像。例如，可以动态地更新显示器以模仿用户通过一个或多个笔和/或橡皮擦对白板进行的输入。交互显示系统可以实现嵌入在显示器内的底层，以通过全内反射来引导从与显示器接合的物体发出的电磁辐射到一个或多个检测器。至少部分地由于底层在将电磁辐射引导到检测器时的效率，交互式显示系统可以增强用户对输入的解释的速度和/或准确性。
