Abstract: A method for determining the position of a non-motorized road user including ascertaining a first geodetic position of the road user in a position determination device, which uses a global navigation satellite system, of the terminal, and transmitting the first geodetic position to a traffic device. In a control unit of the traffic device, ascertaining a second geodetic position of the road user from a geodetic traffic device position and a relative position ascertained from sensor data, showing the road user, of at least one surroundings sensor of the traffic device. At least if a limiting value for a deviation of the first position from the second position is exceeded, transmitting an item of deviation information describing the second position and/or the deviation from the traffic device to the mobile terminal, and using the deviation information to correct the position ascertainment in the position determination device.

Abstract: A method of identifying an object signature in an environment includes acquiring infrared information from the environment using a detection unit in order to obtain an infrared wavelength spectrum associated with the environment. The method further includes selecting three wavelength bands of the infrared wavelength spectrum using a filtering unit and detecting a presence of the three wavelength bands of the infrared wavelength spectrum in the environment by filtering the selected three wavelength bands using the filtering unit. The method further includes determining an intensity indicator for the three selected wavelength bands using a processing unit and classifying the object signature using the processing unit based on the determined intensity indicator in order to identify the object signature.

Abstract: A representation device for representing and interacting with a three-dimensional virtual scenario includes an input unit and at least one representation region for representing the three-dimensional scenario. A marking element may be moved on a virtual surface area with two translational degrees of freedom such that each virtual object in the three-dimensional virtual scenario may be selected with the marking element.

Abstract: A representation device has a first representation region and a second representation region for representing a three-dimensional scenario. The first representation region is disposed in a first plane and the second representation region is disposed in a second plane, the first plane and the second plane forming an included angle ? relative to one another. The angled position reduces conflict between convergence and accommodation in the human visual apparatus, supporting low-fatigue viewing of a three-dimensional scenario.

Abstract: A display device for a three-dimensional virtual scenario for selecting objects in the virtual scenario provides feedback upon successful selection of an object. The display device is designed to output a haptic or tactile, optical or acoustic feedback upon selection of a virtual object.
