A method is for transferring a state from a first VR environment to a second VR environment. In an embodiment, the method includes receiving, via a receiving system, a static object dataset relating to an object, the object being represented in a first VR environment, generated by an input system, and in the second VR environment, generated by the receiving system. In addition, the sending system determines a first dynamic object dataset relating to the object, the first dynamic object dataset relating to a dynamic property of the object in a first VR environment. In addition, the first dynamic object dataset is transmitted from the sending system to the receiving system. In addition, the receiving system determines a first state of the second VR environment based upon the static object dataset and the first dynamic object dataset.

Transferring a state between VR environments

A method to determine the dimensions and distance of a number of objects in an environment includes providing a number of objects including a marking element; recording a visual image-dataset of at least one of the objects with a camera; and determining a parameter value from the image of a marking element in the image-dataset or from a measurement of an additional sensor at the location of the camera. The parameter value is a value depending from the distance of the object to the camera. The method further includes calculating the relative distance between the object and the camera based on the parameter value and calculating dimensions of the object from at least a part of the image of the object in the image-dataset and the calculated distance. A related device, a related system and a related control unit for a virtual reality system are also disclosed.

Method and device to determine the dimensions and distance of a number of objects in an environment

A method includes determining a first position of a thumb and a first position of an index finger at a first time; calculating a first distance between the thumb and the index finger at the first time based upon the first position of the thumb and index finger; determining a second position of the thumb and index finger at a second time, the second time being relatively later in time than the first time; calculating a second distance between the thumb and the index finger at the second time, based upon the second position of the thumb and index finger; identifying a pick-up gesture based upon the first distance and the second distance; selecting a first tool from a set of tools based upon a tool position of the first tool, the first tool being a real tool; and assigning the first tool to the pick-up gesture.
