System and method for displaying information

The invention relates to a system and method for displaying information.

Such a system and method is used, for example, in the field of automation technology, in production and machine tools, in diagnostic / service support systems and for complex components, devices and systems, such as vehicles and industrial machines and systems, in particular in the special context of the application field " Augmented Reality in Service ".

The invention has for its object to improve the provision of information and functions in terms of user friendliness.

This object is achieved by a system and a method with the features specified in claims 1 and 14, respectively.

Many complex activities in the areas of service, maintenance and production require a high level of supporting information and functions in the right place and at the right time. Mobile Augmented Reality (AR) technology provides access to a very extensive database in these areas. Information management systems provide access to a wide range of information, but only a part of this pool is needed to complete a specific task. Which information is required depends on the context and the task of the user. In common information management systems, the user first has to find the information that is of interest to him at the current time, which often means a considerable amount of time. Traditional user interfaces usually require more or less complex search and / or Navigation dialogs to find the relevant information or function. They are mostly static in their structure and look & feel, often offer a variety of options, of which only a part is needed to complete a specific task, and they can only be adapted to the current needs of the user to a limited extent. Further requirements for the user interface of mobile AR systems result from the size of the displays, which are much smaller than PC monitors (so-called "babyface"). In order to avoid overfilling the display (display clutter), only information and functions that are meaningful for the user in his current context should be shown. This applies to an even greater extent to such augmented reality systems in which computer-generated information (for example with a head-mounted display) is superimposed directly in the user's field of vision and thus overlays reality. The difficulty therefore lies in filtering out the information and functions that the user really needs for his task from a very large database and presenting it to him in a suitable form on a mobile AR system.

Up to now, current information management systems have only focused on stationary systems. Widely used graphical user interfaces (desktop metaphor) enable the user to make individual adjustments, such as direct access to frequently required information and functions (e.g. via shortcuts on the desktop) or hiding and modifying toolbars. In common operating systems, search functions are integrated, which have extensive configurable criteria that enable information to be found at the local workplace, in the local network or even on the Internet. There is also a multitude of search engines on the Internet, which often specialize in specific tasks. The option of a full-text search enables you to search for criteria that apply to the Structure of the corresponding information databases have not been taken into account. Offline search systems independently carry out research on the Internet according to user specifications. All current solutions described require a high degree of planning and specific requirements for the system from the user. While the user is generally aware of the context in which he is looking for certain information, he has to communicate this to the system using complex criteria specifications. For short-term tasks, the effort required is often too high to achieve useful results.

The present invention provides a tool in the form of a system for providing information and functions, which is also referred to below as context navigator, which provides the user of mobile AR systems with information and / or functions depending on his context (location, task, people, work object) offering. The context navigator enables fast and efficient access to information from an extensive database by offering the user a sensible pre-selection. This pre-selection is generated dynamically from the current context: Depending on its spatial position, the current work object, the work task and possible communication partners, the user receives a customized selection of information and functions. Spatial context, work objects (e.g. components) and communication partners (other people present) are automatically recorded by the system via AR tracking, work tasks or work processes are monitored and controlled by a workflow engine. The user can decide which of the automatically recognized objects are displayed in his mobile AR system, he can add additional elements manually (e.g. via a search) and he always has direct access to the objects he has selected. The mobile application of a computer system places increased demands on efficient and fast access to the required data compared to the office workstation, offers at the same time the possibility to obtain information from the spatial context about which information or functions are important or useful for the user in the current situation.

The context navigator recognizes the spatial context (location, components, people present) with the help of an AR tracking system and the work context of the user with the help of a workflow engine. Based on this information, the user interface adapts and shows the information and functions that are relevant in the current context - e.g. B. for the current step on the current component - are useful. The context navigator acts like a dynamic filter on the data stock and is therefore able to provide the "suitable" information and functions at the right time. The user has the option of directly accessing several context objects. These are presented to him in the display by context-specific menus, which give access to the respective information and

Enable functions. In these context-specific menus, May contain references to "related" context objects (e.g. to components that are functionally linked to the component currently being processed). The user can remove the context objects presented to him at any time if he no longer needs them.

In the present invention, a tracking system is used, which is a system that can detect and recognize objects (e.g. rooms, machines, components). The

Capture is advantageously carried out via an image capture unit. The recorded information is evaluated in a computer unit. With the help of the tracking system, the location of the user and the context in which he is located are determined and this information is sent to the

Computer unit forwarded. The term context means information that is local, temporal or are functionally related to the user, e.g. These include, for example, his specific work situation, his local environment, his gaze direction and focus, but also the presence of external disturbances or information that could be relevant for the user. The generation of the

Reports of external faults and information are made in the first control means. This also includes the information system, which "filters" through the given contextual information and provides the information that is currently relevant. If a certain context is captured by the tracking system, it forms a so-called context object and appears symbolically in a kind of "task bar" as a "button". By operating these "buttons", ie the second control means, the user can switch between different context objects. Each context object has its own menu, in which u. a. the option is included to abandon the context object. With the help of a tracking system that is common for augmented reality applications, the possibilities and potential of context detection are transferred to the design, structure and organization of a user interface in order to ensure intuitive, fast and user-friendly navigation, orientation and usability. The user remains mobile in that the display device is designed as a display of a mobile computer system. The context navigator and its components are implemented on one or more mobile or stationary computer systems.

The invention is described and explained in more detail below on the basis of the exemplary embodiments illustrated in the figures.

The components used and their interaction are explained below with reference to FIGS. 1 to 3. First, an overview of the terms used is given. A context object 6 contains a filtered data record from a database 7, e.g. B. a database that enables access to information 8 and functions 9. Context objects 6 are generated by the context registration 21, 22 from the real context. The context manager 23 is the central element of the context navigator 30 and is used to manage the context objects 6. The context manager 23 is responsible for ensuring that new context objects 6 are adopted by the user 3 in the context display 29. The granularity controller 24 serves as an additional filter. The objects in the context display 29 are presented to the user 3 in the form of context-specific menus 20. about <£>

Context query matching the main context object. In the next step, the user wants to order 3 spare parts for the defective machine. He activates the context object 16 "Machine" (see FIG 17) and calls the main menu with the corresponding button 19 (see FIG 18). The context-specific menu 20 (see FIG. 19) now relates to the context object 16 of the machine XHC241 as the new main context. 20 shows the displayed list 18 of spare parts. The user 3 can thus manage a large amount of information without having to search for a long time or have his user interface overloaded. For this purpose, he uses the described dynamic and context-dependent display surface 1 and information systems for mobile computing such as the context navigator 30.
