The object is achieved according to the invention in terms of the method by the characterizing features of claim 1 and in terms of

Device solved by the characterizing features of claim 7.

Advantageous embodiments of the invention are the subject of

Dependent claims.

In a method for processing a data set from a

Amount of data with a predeterminable number of files, especially media files, becomes one based on the selected record

Playlist created. According to the invention it is provided that the

Dataset as a set of points in a preconfigurable

Coordinate system is graphically represented, wherein a sequence of the record in the playlist is determined by graphically connecting individual points in the point set.

The graphical representation of the dataset as a set of points in a preconfigurable coordinate system allows a user an optimal overview of the entire amount of data, so that this quickly and efficiently on the basis of the graphically displayed data

Create a playlist by connecting individual points in the set of points. The playlist includes each other connected points, which z. As audio files, video files or

Represent image files.

The interconnected points are plotted as a curve in the coordinate system, the curve being the

Playlist represents. This allows the user to see the playlist at a glance. Furthermore, this results in the

Possibility to change the playlist z. B. on the basis of screenshots to share with other users whose terminals are equipped with appropriate application software, by means of a takeover of the playlist based on the screenshot is possible.

The playlist displayed as a graph can be manually or

be created voice-controlled. For manually creating the curve, the user draws z. B. with a finger a path in the point set, by means of which the individual files are connected to each other. Instead of the finger can also be a tool, such. As a pen, a

Control knob or a computer mouse, to be used. In the case of a voice-controlled creation of the curve, the user can connect the points to one another with the aid of suitable linguistic commands.

The coordinate system in which the curve is shown, has at least two axes, wherein the preconfiguration of the

Coordinate system, one parameter is assigned to each axis. Alternatively, the coordinate system can also be designed as a three-dimensional coordinate system, so that three parameters are available for preconfiguration. The parameters can be selected for example by means of a drop-down menu by the user or are given by the user depending on the configuration of an application software. Thus, the set of points shown in the coordinate system already represents a preselection of the amount of data, so that the User can create the playlist based on the parameters he chooses. This is particularly advantageous if the

Dataset from a database with a very high number of files related. The amount of data is determined by the preconfiguration

reduced accordingly, so that the implementation of the method less resources are needed and the creation of the playlist is so time and cost efficient.

At least one of the parameters is a selection criterion, which is specified as a parameterizable meta-information of a file. A meta-information of a file is additional information, which is stored in the corresponding file. Additional information is

For example, a file type, a creation date, and / or a size of the file. Audio files have more information z. B. in terms of a year of publication, an artist and / or aggressiveness, in which case the year of publication and the aggressiveness

represent configurable meta information. Thus, the user can, for example, create a playlist of audio files which, depending on a meta-information, eg. B. the aggressiveness, in the

Coordinate system are arranged. Other media files, such as video and image files, have similar and / or different ones

Metainformationen, z. As a length of time of the video or a

Shooting date of the image, on.

A device for processing a data record from a

Amount of data containing a number of files, especially media files, to create a playlist based on the selected one

Record, comprises at least one display unit and a coupled thereto control unit. According to the invention, the display unit has a graphical user interface, by means of which the amount of data as a set of points in a preconfigurable coordinate system and a by a user specific sequence of the record in the

Playlist can be displayed as a curve. The graphical user interface serves the user-friendly operation of an application software implemented in the control unit. The user can create the playlist by drawing a path in the set of points.

The above-described characteristics, features, and advantages of this invention, as well as the manner in which they will be achieved, will become clearer and more clearly understood in connection with the following description of exemplary embodiments which will be described in detail in conjunction with the drawings. Showing:

FIG. 1 schematically shows a graphical user interface which displays a playlist of media files in a first exemplary embodiment,

FIG. 2 schematically shows the graphical user interface which displays a playlist of media files in a second embodiment, and FIG

Figure 3 schematically shows the user interface, which a

Playlist with media files in a third

Indicates embodiment.

Corresponding parts are provided in all figures with the same reference numerals.

FIG. 1 schematically shows a graphical user interface 1, which comprises a coordinate system 2 with a longitudinal axis y, a transverse axis x and an axis extending in the coordinate system 2 graphically represents the parabolic curve 3, wherein the curve 3 a

Playlist with selected media files.

The graphical user interface 1, also as graphical

User interface known, is implemented in a display unit, not shown, which, for example, in a vehicle as part of a central control unit (= infotainment system), a

Mobile device or smart phone, tablet PC's, a high-fidelity system, a personal computer, a notebook or any other multimedia device is arranged.

The display unit is not limited to an arrangement in the vehicle. For example, the display unit is part of a

Mobile device or smartphone on the road or at home as a screen of a home computer usable. Alternatively, the

Display unit also via a mobile network, via radio, z. B. via Bluetooth or WLAN, or be coupled via so-called cloud networks with a terminal.

The graphical user interface 1 serves the user-friendly operation of an application software, which allows in particular a selection and playback of media files. The application software includes or has access to a database that includes a number of these media files. For example, the database is on a

Smartphone stored so that the application software and the

Database are implemented in the same terminal. It is also conceivable that the database is stored in another terminal or network to which the application software has access. For example, the database consists of media files of certain online radio stations or online services which transmit media files in real time. Among media files audio files, z. B. in MP3 format, video files, z. In MPEG format, and image files, e.g. In JPEG format.

Such media files usually have a format for

Additional information, called meta-information, on which in the example of an audio file information regarding z. As a song title, an artist, a year of publication, a genre, a

Aggressiveness of the song, etc. This meta information is stored as a character encoding in the corresponding media file.

In the present first embodiment, the longitudinal axis y represents a meta-information of an audio file. In the case of meta information, this is an aggressiveness of a song, i. H. as how loud and / or fast (= high aggressiveness) or how calmly and / or slowly (= low aggressiveness) a song is perceived by a listener. The aggressiveness is stored as a parameter with a certain value in the audio file. The transverse axis x represents the time in the present embodiment, wherein the length of the transverse axis x

For example, represents a calculated by a navigation device travel time.

The user has the possibility to configure the axes x, y according to his ideas. This is in the graphical

User interface 1 integrated a suitable control, which is graphically represented for example in the form of a so-called drop-down menu, and by means of which certain meta-information can be assigned to the axes x, y Additionally, it is possible

Determine parameters of the axes x, y, which are given by online databases and / or online service providers. In addition to the meta-information aggression, the longitudinal axis y can also be assigned the year of publication, the artist or a duration of the song, a recording date of an image file, as shown in FIG. 3, or any other arbitrary parameterizable meta-information.

The time which is represented by the transverse axis x in the first exemplary embodiment is, for example, via the drop-down menu by the user or depending on a timer or via a timer

Web interface or using an electronic calendar

pre-configured.

The above-described assignment of the parameters to the axes x, y can be done by a manual input of the user or by voice control. Alternatively or additionally, it is possible that the

Application software that predefines the axes x, y.

When the pre-configuration is completed, the graphical user interface 1 displays to the user the coordinate system 2 in which, depending on the preconfiguration of the axes x, y, a selection of media files from the database is displayed.

In the present first embodiment, the user of the

Longitudinal axis y the metainformation aggressiveness and the transverse axis x the time whose length z. B. is specified by the user assigned.

Then the user is the coordinate system 2 with the

corresponding axes x, y displayed, wherein in the coordinate system 2, the appropriate selection of media files, in particular

Audio files, depending on the metainformation aggressiveness is graphed. The selected audio files are represented here as a cloud of points, not shown here, in the coordinate system 2, one point representing an audio file. The transverse axis x divides the coordinate system 2 into two regions B1, B2, which are determined on the basis of the values of aggressiveness, that is to say over the longitudinal axis y. That is, an upper area B1 represents a range of audio files containing low-aggressiveness songs. On the other hand, a lower area B2 includes audio files containing songs with a relatively high aggressiveness.

Following this, the user has the option of having one

corresponding input to determine the sequence of media files, in particular audio files, in the playlist over the predetermined time.

To do this, the user connects the points in the point cloud by drawing any path through the point cloud, which is called the point cloud

corresponding curve 3 is displayed in the coordinate system 2. The drawing of the path is done by touching a finger of the

User and a desired waveform corresponding displacement of the finger on the display unit. Instead of the finger can also be a suitable tool, such. As a pen, a

Control knob or a computer mouse are used. Furthermore, a voice control for drawing the curve 3 is conceivable. The detection of the user input is done using known from the prior art means and methods.

The user-drawn curve 3 is displayed to the user after detecting them on the graphical user interface 1. In the first embodiment, this, as already mentioned, a

approximate parabolic shape, wherein a vertex S of the curve 3 in the upper region B1 and a start a and an end b of the curve 3 in the lower region B2 are arranged. For example, does the time correspond to one Driving time, the user desires at the beginning of the ride songs with a higher aggressiveness, so loud and fast songs that are slower and slower in the course of time, with the aggression of the songs rises again at the end of the ride.

The representation of the playlist as a curve 3 can also be changed before or during a playback of the audio files by the user, so that the playlist is displayed for example in the form of a list. Furthermore, it is possible for the user to select a different audio file by a specific gesture during playback of the audio files. For example, the user touches the

Display unit at a certain point of the curve 3 and selects an audio file that would originally be played at a later date. It is also conceivable that the user can forward and / or rewind the playlist by touching and moving the finger or aid on the display unit. Moreover, it is possible that the user can increase or decrease the curve 3 by a spreading gesture already known from the prior art, the user receives an improved view of individual, arranged in the playlist, audio files as the curve 3. Furthermore, during playback of the audio files, the user can

Pause playback and create a new playlist by drawing a curve 3 again.

The playlist shown as curve 3 can also be made available to other users and / or terminals via cloud networks, e-mail and / or social networks. For example, a terminal on a corresponding application software, which is able to take on the screen based on a screen shot of the curve 3 on the terminal and play accordingly. In an alternative, not shown embodiment, the coordinate system 2 is formed in three dimensions, so that for

Preconfiguration three parameters are available. In this case, for example, a thickness of the curve 3 could represent the third parameter. With regard to the first embodiment, the third parameter represents z. B. additionally a year of publication of a song.

The invention is explained below with reference to further exemplary embodiments, FIG. 2 showing a second and FIG. 3 a third

Embodiment shows.

The second embodiment is analogous to the first

Embodiment, a curve 3 with parabolic shape, which a

Playlist of audio files. The longitudinal axis y is also assigned here the metainformation aggressiveness. The transverse axis x is associated with a further meta-information, in particular a year of publication of a song. Thus, the coordinate system 2 has four

Areas B1 .1, B1 .2, B2.1, B2.2.

In an upper left area B1 .1 audio files are arranged with songs of low aggressiveness and years of publication, for example, from 1950 to 1980. An upper right area B1 .2 has audio files with songs also of low aggressiveness and release years from, for example, 1980 to 2013. On the other hand, in a lower left area, audio files with high aggressiveness songs are

Publication years arranged analogously to the upper left area B1 .1. A lower right area B2.2 has audio files with songs also high aggressiveness and years of publication analogous to the upper right area B1 .2 on. The time is given here, which, for example, one of

Sat the navigation device calculated travel time, the time by extending or shortening the curve 3 in the direction of the transverse axis x is correspondingly variable. Thus, based on the curve 3 at the beginning of the predetermined time, audio files corresponding to the lower left area B2.1, then corresponding to the upper left area B1 .1, the upper right area B1 .2 and the end of the predetermined time corresponding to the lower right area B2 .2 reproduced.

The third embodiment shown in Figure 3 shows a

Playlist of image files. The longitudinal axis y is here

Meta information associated with the recording date of an image. The transverse axis x is associated with the time analogous to the first embodiment. The

Coordinate system 2 has an upper region B1 and a lower region B2, in which case the upper region B1 has image files with images with an older recording date than in the lower region B2.

The curve 3 runs starting from the zero point of the transverse axis x approximately linearly descending, so that over the course of time, the reproduced images increasingly current recording data. Alternatively, instead of the meta information recording date also any other

parameterizable meta-information of image files can be selected.
