A computer-implemented method for computer-aided tracking of a procedure to be performed by a person, wherein the method comprises the following steps: - identifying the person by a terminal device immediately before the person performs the procedure with: - capturing of biometric data of the person by the terminal device; and - comparing of the captured biometric data with biometric data of a personal data set by the terminal device, wherein the personal data set is stored in a storage unit of the terminal device; - identifying at least one object to be modified by the procedure by the terminal device immediately before the procedure is carried out with: - capturing an object identification data set by the terminal device, wherein, therefor, a machine-readable data set (210, 220) is captured by a capturing unit, in particular a camera, of the terminal device, and the machine-readable data set (210, 220) of the object is validated by querying a corresponding object identification data set in a background system; and - comparing the captured object identification data set with the object identification data set or the procedure data set of a background system; - tracking at least one position of the person and at least one position of the at least one object by the terminal device by methods of computer-aided gesture and/or pattern and/or image recognition during the performance of the procedure; - instructing the person to perform the procedure by the terminal device during the performance of the procedure; and - documenting the performance of the procedure by capturing images at one or more random times during the performance of the procedure by a camera of the terminal device and storing this procedure documentation locally in the terminal device in a procedure-identification data set. - identifying the person by a terminal device immediately before the person performs the procedure with: - capturing of biometric data of the person by the terminal device; and - comparing of the captured biometric data with biometric data of a personal data set by the terminal device, wherein the personal data set is stored in a storage unit of the terminal device; - capturing of biometric data of the person by the terminal device; and - comparing of the captured biometric data with biometric data of a personal data set by the terminal device, wherein the personal data set is stored in a storage unit of the terminal device; - identifying at least one object to be modified by the procedure by the terminal device immediately before the procedure is carried out with: - capturing an object identification data set by the terminal device, wherein, therefor, a machine-readable data set (210, 220) is captured by a capturing unit, in particular a camera, of the terminal device, and the machine-readable data set (210, 220) of the object is validated by querying a corresponding object identification data set in a background system; and - comparing the captured object identification data set with the object identification data set or the procedure data set of a background system; - capturing an object identification data set by the terminal device, wherein, therefor, a machine-readable data set (210, 220) is captured by a capturing unit, in particular a camera, of the terminal device, and the machine-readable data set (210, 220) of the object is validated by querying a corresponding object identification data set in a background system; and - comparing the captured object identification data set with the object identification data set or the procedure data set of a background system; - tracking at least one position of the person and at least one position of the at least one object by the terminal device by methods of computer-aided gesture and/or pattern and/or image recognition during the performance of the procedure; - instructing the person to perform the procedure by the terminal device during the performance of the procedure; and - documenting the performance of the procedure by capturing images at one or more random times during the performance of the procedure by a camera of the terminal device and storing this procedure documentation locally in the terminal device in a procedure-identification data set.
