Abstract: A method for determining vital parameters of a human body using a device with at least one optical recording unit and a computing unit includes the following steps: recording a sequence of individual image data of a single limited area of the skin of the human body using the optical recording unit; evaluating the image data, including determining a pulse wave transit time; and determining vital parameters of the human body from the image data using the computing unit. Further, a device determines vital parameters. In addition, a method authenticates a person and a method identifies a reaction of a person.

Abstract: The Invention relates to a method for determining vital parameters of a human body by means of a device (10) with at least one optical recording unit (11) and a computinig unit (12), said method comprising the following steps: recording a sequence of Individual image data of a single limited area of the skin (30) of the human body by means of the optical recording unit (11); evaluating the image data, including determining a pulse wave transit time; and determining vital parameters of the human body from the image data by means of the computing unit (12). The invention further relates to a method for authenticating a person and to a method for identifying a reaction of a person.
