Abstract: A method for conducting group travel, wherein a subsequent group travel participant follows a group travel participant travelling ahead or the subsequent group travel participant drives to a current destination of group travel participant travelling ahead, includes the steps of: assigning a group travel identifier for a journey of the group travel participant travelling ahead; passing on the group travel identifier from the group travel participant travelling ahead to the subsequent group travel participant; transmitting navigation information of the group travel participant travelling ahead to a distribution unit in a context with the group travel identifier; transmitting the navigation information from the distribution unit to the subsequent group travel participant; and using the navigation information transmitted from the distribution unit by the subsequent group travel participant.

Abstract: The invention relates to a communication system having a display unit (2) and a virtual being (3) that can be visually represented on the display unit (2) and that is designed for communication by means of natural speech with a natural person, wherein at least one interaction symbol (6, 7) that can be represented on the display unit (2) and by means of which the natural speech dialog between the virtual being (3) and the natural person is supported such that an achieved dialog state can be indicated and/or additional information depending on the dialog state achieved and/or information can be redundantly invoked. The invention further relates to a method for representing information of a communication between a virtual being and a natural person.
