The present application claims priority to Application No. 20 2013 000 751.6, filed in the Federal Republic of Germany on Jan. 25, 2013, which is expressly incorporated herein in its entirety by reference thereto.
The present invention relates to a device for displaying a multitude of planar objects arranged in at least one stack, having a display area, preferably arranged as touchscreen, for displaying the at least one stack of objects; a processing unit which is able to generate and modify graphics data of the objects; and a proximity ascertainment sensor for detecting an operating element in a proximity region in front of the display area or in front of an input device. In addition, the present invention relates to a method for displaying a multitude of planar objects, arranged in at least one stack, on a display area.
A motor vehicle is equipped with different information and communication areas to which display instruments are assigned. They are provided to inform the driver and the passengers. Furthermore, they can assist the driver in the navigation or the communication with the outside world. The display may visually display traffic- or vehicle-related data, for example. A so-called instrument cluster is typically disposed near the driver's primary field of vision. For example, it displays the speed, the tank content level and other information of the motor vehicle related to its operation. In addition, it is possible to display radio and audio functions.
Because of the rising number of electronic devices in motor vehicles, it has become quite common these days to equip vehicles also with a display and operating system that has a graphical user interface in order to allow an intuitive operation and control of the various electronic devices in the vehicle. For example, it is desirable in this context to display the information such that the driver is able to absorb it rapidly and intuitively, so that the comprehension of the displayed information does not distract the driver from driving. Furthermore, the operation should be intuitive, simple and quick so that the driver is able to operate the devices of the vehicle for which the information is displayed by the display device, even while driving. The display of information and the operation associated with a display of information in the motor vehicle thus increase the safety while driving the motor vehicle.
German Published Patent Application No. 10 2007 039 445 describes a device for displaying information on a display area in a motor vehicle. The device has a processing unit and a proximity sensor system, which detects an approach of an operating element in the direction of the display area, the display switching from a display state to an operating state when the display area is approached.
Example embodiments of the present invention provide a device and a method for displaying a multitude of planar objects arranged in at least one stack, which, in the pure display state, gives the user a rapid overview of as many pieces of information as possible. As soon as an operating intention is detected, a rapid change takes place from the display state to an operating mode, in which the user is provided with a multitude of operating options that allow a simple and intuitive selection of the objects.
According to example embodiments of the present invention, the processing unit of the device for displaying a multitude of planar objects arranged in at least one stack is configured such that the graphics data of the objects are generated so that the at least one stack of objects is displayed in different display states in the display area, i.e., in a first mode, which preferably is a pure display mode; in a second mode, in which an operating element is detected in the proximity region in front of the display area or in front of an input device; and in a third mode, following the touching or selection of the display area or an object displayed on the display area.
The processing unit may be configured such that the graphics data of the objects in the first mode are generated so that the first object of the at least one stack is displayed on the display device. The first object preferably is the currently selected object, so that in the display state, this is the most important information for the user in this particular state when, for example, images (covers) of albums or music pieces are shown. This may also be the first object of the stack or the object of the stack that was selected last.
The processing unit may be configured such that the graphics data of the objects in the second mode are generated so that the individual objects of the at least one displayed stack are displayed substantially one behind the other, preferably in overlapping fashion, so that the user very rapidly gets a general idea as to whether objects are included in the stack, and how many.
However, it may also be the case that in the first mode, the graphics data of the objects are generated such that the individual objects of the at least one displayed stack are displayed one behind the other, preferably in overlapping manner, so that in display mode, the user is provided with an overview of the objects located within the stacks. In the second mode, only one object of the displayed stacks of objects will then be displayed in order to make it easier for the user to select a stack from which he wants to choose objects in the third mode.
The processing unit may be configured such that in the third mode, the graphics data of the objects are generated such that the individual objects of the at least one stack are displayed at an offset one behind the other, at a greater distance from each other than in the second mode, for the selection of the objects with the aid of the operating element. This gives the user the chance to call up and/or select individual objects of a stack in an uncomplicated manner.
It may furthermore be provided that at least two stacks of objects are displayed in the first and second mode, but that only the selected stack is displayed once a stack has been selected with the aid of the operating element.
The processing unit may be configured such that when the first displayed object is touched by the operating element, or when the first displayed object of a stack displayed on the display area is selected with the aid of an input device, a change takes place from the second to the third mode.
In a method for displaying a multitude of planar objects arranged in at least one stack on a display area, graphics data of the objects included in the at least one stack are generated such that in a first mode, the at least one stack of objects is shown in a first display state. In the second mode, when a proximity ascertainment device detects an operating element such as the finger or the hand of a user in a proximity region in front of the display area or in front of an input device, e.g., an operating device for controlling a cursor on the display area, the at least one stack of planar objects will be shown in a second display state. In a third mode, following the selection by means of a cursor, or following touching of the display area or of an object shown on the display area, the at least one stack of objects is shown in a third display state.
Only the first object of the at least one stack of objects may be shown on the display area in the first mode. In the display of media data, for example, this could be the currently selected album or song. The first mode may be a pure display mode, which is arranged for an optimal display of the objects in order to provide the driver with an intuitively comprehensible display in an arrangement of the display area in a vehicle.
The individual objects, or a subset of the objects, of the displayed stacks may be substantially displayed one behind the other and in partially overlapping form in the second mode.
The graphics data of the objects in the first mode may be generated such that the individual planar objects, or a subset of the objects, of the displayed stacks are/is shown substantially one behind the other in overlapping form, so that in display mode, the viewer is provided with a rapid overview of the approximate number of objects in the stack. In this configuration, it may be the case that only one object of the shown stacks is displayed on the display area in the second mode.
In the third mode, the stacks of planar objects are shown optimized for an operation or selection. The individual objects, or a subset of the objects, of the displayed stacks may be displayed at an offset one behind the other and in overlapping form, at a distance that allows an unambiguous selection of the individually desired object.
At least two stacks of objects may be displayed on the display area.
In addition, in the third mode, i.e., the operating mode, it is possible that only the selected stack of objects is shown on the display area, even if multiple stacks were shown in the first and second mode.
The device may be used in vehicles for the display and operation of electronic devices in the vehicle or of vehicle-related functions, and also in mobile devices, to operate media or telephone functions. Other areas of use are also possible.
