Problems solved by technology
The disadvantage here is that the terminal is not always in the user's field of vision, or the reading of the display endangers the safety of the user in many cases, e.g. as a forklift driver in a warehouse, on scaffolding, etc.
[0006] Vibration alarms, ie notifications in the form of vibrations of the terminal, have the disadvantage that the vibrations can only be felt when the user wears the terminal directly on the body or under protective or work clothing
Therefore no information about spatial proximity / distance or direction to the information can be conveyed
[0007] In the case of visualization within an Augmented Reality (AR) display, that is, either additional information about the visible object is displayed in the image of the video camera or the line of sight is directly augmented with the aid of a special see-through display When it comes to reality, physical and visual limitations disadvantageously arise through wearing / using AR displays

Embodiment Construction
[0017] figure 1 A common hard hat with three transverse straps and one adjustable circumferential strap is shown in two views. According to the invention, in the area above the left and right ears of the helmet wearer, the bone sound loudspeaker unit L is respectively inserted in the adjustable circumferential band, and in the area between the crown and the transverse band. Orientation sensor RS.
[0018] The orientation sensor RS contains a digital compass and an inclination sensor and uses the earth's magnetic field to determine the orientation of the helmet. The inclination sensor is necessary because otherwise the orientation of the head cannot be unambiguously calculated from the measured geomagnetic field.
[0019] By means of the bone-acoustic loudspeaker worn directly on the skull, the user can be informed spatially of location-related information in the user's surroundings.
[0020] figure 2 Shows a schematic illustration of an embodiment of a total system accor...

The invention substantially consists of improving a safety helmet around bone conduction speakers and directional sensors such that the carrier can be alerted of positional information in the surroundings thereof via spatially directed auditive signals - relative to the orientation of the scull. The notification of the user is carried out via different context-dependent auditive signals calculated in real time from the position of the user, the orientation of the head and the position of the information, these signals being output via said bone conduction speakers, wherein the perceived sound source equals the position of the information. Depending on whether the user carries a mobile phone, a PDA, table PC or other handheld computer, the user is notified in different ways about a changing state of the software or the system. The bone conduction transmission ensures that the notification signal can be perceived independently of ambient noise. The invention is intended to be mainly used in the domains of location based services, augmented reality, human machine interface (HMI) and industry.
Description
technical field [0001] The invention relates to a system for communicating or publishing location information, that is to say information assigned to or addressable by a location. Background technique [0002] The invention described here mainly relates to location-based services as mobile location-related information services, which are provided on mobile terminal devices such as PDAs, tablet PCs or mobile phones by means of location-, time- and person-related data. End users provide optional information. Such information can be visible on the mobile terminal only when it is actually in the vicinity, such as user manuals for complex devices, maintenance tasks for machines, plans or also warning indications. Conceivable fields of use of this technology are construction sites, mines, etc., in addition to large industrial plants. [0003] Due to the changing location or temporal and spatial context of an end user, there is a need to inform the end user of new and updated inf...
