A highly sensitive movable touchpad is disclosed in the present invention. It is used for laptop computers and has a slidable template for users to move so that a cursor can be controlled by the touchpad. A resistive or capacitive detecting surface can be applied for detecting users' click, double click, drag, or scroll motion on any point of the surface. Additionally, there is an optical displacement sensor provided under the slidable template for detecting surface information on the back surface of the slidable template. A sequence of images of surface movement are processed by an image processing unit. Then, relative movement information is calculated and sent to an operating system in the computer. The operating system controls the cursor with the relative movement information. The present invention uses edge detectors for dynamically controlling the cursor and calibrating location of the cursor so that positioning of the touchpad is synchronous with the cursor.

The present invention provides a calibration method of projection effect. The calibration method of projection effect according to the invention comprises the following steps. The first, step (a) is performed to make an optical navigation system move along a predetermined trace relative to an object plane. Then, step (b) is performed to sense the predetermined trace by a sensor to obtain a projection trace. The next, step (c) is performed to calculate a projection effect value according to the included angle between a reflected light and the object plane. Finally, step (d) is performed to calibrate the projection trace with the projection effect value to obtain a calibration trace which is in proportion to the predetermined trace.

The present invention mainly provides a precision calibration method for being applied in a high-precise rotary encoder system, wherein the primary technology feature of the precision calibration method is that: using a laser speckle image capturing module to capture N frames of laser speckle image from an optical position surface of a rotary encoding body, and then using image comparison libraries and particularly-designed mathematical equations to calculate N number of image displacements, so as to eventually calculate N number of primary variation angles and sub variation angles corresponding to the N frames of laser speckle image. Therefore, after the rotary encoding body is rotated by an arbitrary angle, an immediate angle coordinate can be precisely positioned according to the primary variation angles, the secondary variation angles and the N number of image displacements.
