The present disclosure is a method for the generation and integration of physical information in multimedia files synchronously, to be played in mobile phones, tablets, and other electronic devices, to represent physical and mechanical magnitudes related with the action being recorded andor played. Methods of using the device are also disclosed. The input and output auxiliary information include inverting codes, parity codes, temperature information or time delay information. An assist control unit then provides an assist item for a backing operation relative to either the reverse departure or the reverse parking, which is determined to be performed. The measuring uncertainty andor maximum measuring error of the tester is then derived from the determined value of PDL of the verification element in conjunction with the actual value of PDL of the verification element. A development step is performed to remove the previously unexposed parts.
