10. A method for digitizing analog recorded data recorded with an electronic device according to claim 1 , for simultaneous detection of analog and digital data, comprising the steps of:

Step 1: activating the electronic device;

Step 2: calibrating an IMU sensor calibrated to a camera reference system by localizing the camera reference system via a detection and storage of at least two corners and at least three edge lines of a recording medium;

Step 3: recognizing by the electronic device a status “device on recording medium” via a contact sensor

Step 4: detecting motions/fine motions in form of analog recordings of the electronic device or a writing tip by a laser tracker in the localized recording medium and storing, processing and/or digitizing the detected motions as data;

Step 5: absolute localizing of a position of the writing tip in the status “device on recording medium” in a coordinate system of the recording medium, via the at least two visible/detectable corners and the three visible/detectable edges of the recording medium for the camera system, for detecting a position of the device;

Step 6: fusing sensor data, to localize the recorded fine motions of the writing tip in the analog writing or drawing process on the recording medium with aid of data calculated in step 5, provided that the fine motions of the writing tip are correctly tracked and recorded on the recording medium using the laser tracker, and also the absolute localization of the writing tip is performed on the recording medium;

Step 7: storing image data, including the fused sensor data of the fine motions, recorded in the status “device on recording medium” and digitized, and simultaneously storing the image data by an evaluation software as a time-dependent optically represented data record; and

Step 8: transmitting data records to any terminal for reconstructing, further processing, rendering and resaving.
