System for guiding an operator when compacting concrete

A method for guidance of an operator during concrete compaction using a handheld concrete compaction device, comprising:

• storing planning data, wherein the planning data are used to define specific locations in a defined region at which concrete compaction is to be performed using a vibrating unit of the handheld concrete compaction device, and to define a sequence of the locations in which the concrete compaction is to be performed;
• determining the respective current position of the vibrating unit of the handheld concrete compaction device based on a location of a receiver device carried by the operator including:
• using a surface position determination device to determine the position of the receiver device in a plane;
• determining the orientation (A) of a working direction of the operator;
• and
• correcting the position of the receiver device with an offset (O) in the direction of the orientation (A) of the working direction and, thus, for determining the position (P2) of the vibrating unit in the plane;
• determining a depth of the vibrating unit of the handheld compaction device based on a depth position determination device;
• and
• displaying the specific location in the sequence of locations within the defined region at which concrete compaction is currently to be performed and/or the specific location in the sequence of locations at which concrete compaction is to be performed next.
