DEVICES AND METHODS FOR GENERATING INPUT

Devices and methods are disclosed for generating input. In one implementation, a stylus is provided for generating writing input. The stylus includes an elongated body having a distal end, and a light source configured to project coherent light on an opposing surface adjacent the distal end. The stylus further includes at least one sensor configured to measure first reflections of the coherent light from the opposing surface while the distal end moves in contact with the opposing surface, and to measure second reflections of the coherent light from the opposing surface while the distal end moves above the opposing surface and out of contact with the opposing surface. The stylus also includes at least one processor configured to receive input from the at least one sensor and to enable determining three dimensional positions of the distal end based on the first reflections and the second reflections. 公开了用于产生输入的设备和方法。在个实施例中，提供了种用于产生书写输入的触控笔。该触控笔包括具有远端的长形主体，以及被配置为向邻近远端的相对表面上投射相干光的光源。该触控笔还包括至少个传感器，该至少个传感器被配置为当远端与相
