== Topic ==
MP3 Archive Visualization

== Description of the Application Area and given Dataset ==

=== Application Area Analysis ===
The application area is the creation of a MP3 archive visualisation and its ID3 tags. This should contain information like the name of the artist, the year it came out, name of the album etc. 
ID3 tags store information within the MP3 files. Originally ID3 tags held just the basic text-only information about a music file. They had a standard size and standarized information. 
The most important and also special thing about this Project ist to create a useful visualisation, which can store lots of information in one place, without having to abstain from a user friendly interface.

=== Dataset Analysis ===
In the following Table, you can find the attributes which should be contained in a MP3 file. These attributes are 1-dimensional. 
A MP3 file contains only attributes with data.

== Target Group Analysis ==

=== Who should use this visualation technique? ===

In the past years media is getting much smaller, much better in quality, and also provide more space for our data. If you convert conventional audio files from CDs to the MP3 Format, you can afford to have your whole music collection on one larger hard drive. The business within the musich industry is taking over the internet. You are either able to download song, or listen to them directly through streams. So your favorite song ist just a click away! 
Because of the fact that this new art of saving your songs, albums and so on, does not contain the usually shipped cd covers which were a very good visualisation of the audio you are listening to, it has become very important to find a good solution for the visualisation of your music archive. 
At this moment the target group are mostly the people who already use the MP3 format to store their audio data, but should expend soon to all the other music-lovers.

=== What are the characteristics of the target group? ===
Like we already mentined (2.1) the business with the music is spreading more and more towards the internet. So over the years there are going to be developed more and more solutions (e.g. for children, elders, amaurotics etc.) for the music market place.
The target group is going to expand over the years.

=== Are there any known / often used Methods / Visualisation Techniques? ===

The most popular program for MP3 files is nowadays iTunes von Macintosh (Apple). This is mostly due to the big boom in the distribution of the iPod in the past few years. In order to manage the music archive, iTunes uses a XML (Extensible Markup Language). In this xml file, the metainformation is stored, independent from the proprietary audio format which e.g. use ID3 tags. The advantage is that the metainformation nevertheless can be edited, even if the audio files don't allow modificatoins to their tags. Besides iTunes contains a visualizer for different music genres and can encode (import) and decode (play-back) music in different audio formats, except for music samples which is bought in the protected AAC-format.

== Purpose of the Visualisation ==

=== What should be achieved with the Visualisation? ===
Information should be displayed clearly and intuitinal. The user should have a clear view of the information, be able to orient him/herself, and always know that the information displayed is about a music sample.

=== Which tasks should be solved? ===
A solution should be found which can be suitable for young and old, but also for the power and "less"-listeners. The problem is that presentation mostly functions and in fact is very subjective. On the one side the user want't to have as much information as possible displayed, and on the other side one want't to see only the relevant data. 
A good compromise should be found and developed.

=== Questions that can be solved using this Visualisation ===

* Which title is being played back at this very moment?
* Which interprets are avalible?
* Which titles are avalible?
* How many titles from a certain genre are avalible?
* Has the design been propertly developed?
* Is the View / Information shown user friendly and straightforward?

== Designproposal ==

=== Which kinds of Visualisation should be used? ===
* Search for genre and interpret
* Filtered search output should be displayed in an information window
* View (display) and selection possibility for the genres
* View (display) of the current title and interpret
* Scrolling list up & down
* View (display) for the interprets
* Colored distinction of the amount of titles through intervals 

The detail pannel stays clear until an artist or title is selected and afterwards gets filled with all the information.

=== Visual Mapping ===
* Dimension "MP3 Anzahl" --> visual attribute "colored square"
The amount of titles is characterised in terms of color, e.g. blue for 0-500 MP3 files
* Dimension "Interpret" --> visual attribute "table"
Information should be displayed as a table
* Dimension "Genre" --> visual attribute "table"
Information should be displayed as a table

=== Description of Used Techniques / Applied Principles ===

=== Possibilities of the Interaction ===
Through the selection of a genre, the user is able to select an interpret/title. This yields to display of detailed information and possibility of play-back. When adding a title, the color should change.

* Information about the amout of the titles/genre
* Output of the information in the ID3 tags
* Navigation in the single windows with scrolls in order to get more detailed information
* Output for the filtered search results
* Player for play-back of the selected title

=== Mockup(s) / Fake Screenshot(s) ===

MP3 Archive Visualization

== Description of the Application Area and given Dataset ==

=== Application Area Analysis ===
The application area is the creation of a MP3 archive visualisation and its ID3 tags. This should contain information like the name of the artist, the year it came out, name of the album etc. 
ID3 tags store information within the MP3 files. Originally ID3 tags held just the basic text-only information about a music file. They had a standard size and standarized information. 
The most important and also special thing about this Project ist to create a useful visualisation, which can store lots of information in one place, without having to abstain from a user friendly interface.

=== Dataset Analysis ===
In the following Table, you can find the attributes which should be contained in a MP3 file. These attributes are 1-dimensional. 
A MP3 file contains only attributes with data.

== Target Group Analysis ==

=== Who should use this visualation technique? ===

In the past years media is getting much smaller, much better in quality, and also provide more space for our data. If you convert conventional audio files from CDs to the MP3 Format, you can afford to have your whole music collection on one larger hard drive. The business within the musich industry is taking over the internet. You are either able to download song, or listen to them directly through streams. So your favorite song ist just a click away! 
Because of the fact that this new art of saving your songs, albums and so on, does not contain the usually shipped cd covers which were a very good visualisation of the audio you are listening to, it has become very important to find a good solution for the visualisation of your music archive. 
At this moment the target group are mostly the people who already use the MP3 format to store their audio data, but should expend soon to all the other music-lovers.

=== What are the characteristics of the target group? ===
Like we already mentined (2.1) the business with the music is spreading more and more towards the internet. So over the years there are going to be developed more and more solutions (e.g. for children, elders, amaurotics etc.) for the music market place.
The target group is going to expand over the years.

=== Are there any known / often used Methods / Visualisation Techniques? ===

The most popular program for MP3 files is nowadays iTunes von Macintosh (Apple). This is mostly due to the big boom in the distribution of the iPod in the past few years. In order to manage the music archive, iTunes uses a XML (Extensible Markup Language). In this xml file, the metainformation is stored, independent from the proprietary audio format which e.g. use ID3 tags. The advantage is that the metainformation nevertheless can be edited, even if the audio files don't allow modificatoins to their tags. Besides iTunes contains a visualizer for different music genres and can encode (import) and decode (play-back) music in different audio formats, except for music samples which is bought in the protected AAC-format.

== Purpose of the Visualisation ==

=== What should be achieved with the Visualisation? ===
Information should be displayed clearly and intuitinal. The user should have a clear view of the information, be able to orient him/herself, and always know that the information displayed is about a music sample.

=== Which tasks should be solved? ===
A solution should be found which can be suitable for young and old, but also for the power and "less"-listeners. The problem is that presentation mostly functions and in fact is very subjective. On the one side the user want't to have as much information as possible displayed, and on the other side one want't to see only the relevant data. 
A good compromise should be found and developed.

=== Questions that can be solved using this Visualisation ===

* Which title is being played back at this very moment?
* Which interprets are avalible?
* Which titles are avalible?
* How many titles from a certain genre are avalible?
* Has the design been propertly developed?
* Is the View / Information shown user friendly and straightforward?

== Designproposal ==

=== Which kinds of Visualisation should be used? ===
* Suchfenster für Genre & Interpret
* Gefilterte Suchergebnisse werden ausgegeben im Informationsfenster
* Anzeige und Auswahlfenster der Genres
* Playerfenster mit aktuell laufendem Lied und Interpreten
* Scrolling list up & down
* Anzeigefenster des Interpreten
* Farbliche Unterscheidung der Liederanzahl durch Intervalle
The detail pannel stays blanc until an artist or song is selected and anfterwards gets filled with all the information.

=== Visual Mapping ===
* Dimension "MP3 Anzahl" --> visuelles Attribut "farbliches Viereck"
Die Anzahl der Lieder wird farblich gekennzeichnet, zB blau für 0-500 MP3s
* Dimension "Interpret" --> visuelles Attribut "Tabelle"
Informationen werden im Anzeigefenster als Tabelle angezeigt
* Dimension "Genre" --> visuelles Attribut "Tabelle"
Informationen werden im Anzeigefenster als Tabelle angezeigt

=== Description of Used Techniques / Applied Principles ===

=== Possibilities of the Interaction ===
Durch Auswählen eines Genres, kann ein Interpret/Lied gewählt werden. Dies führt zur Anzeige der Details und zur Möglichkeit, das Lied abzuspielen. Beim Hinzufügen von Songs, kann sich auch die Farbe ändern.

* Information über Liederanzahl/Genre

MP3 Archive Visualization

== Description of the Application Area and given Dataset ==

=== Application Area Analysis ===
The application area is the creation of a MP3 archive visualisation and its ID3 tags. This should contain information like the name of the artist, the year it came out, name of the album etc. 
ID3 tags store information within the MP3 files. Originally ID3 tags held just the basic text-only information about a music file. They had a standard size and standarized information. 
The most important and also special thing about this Project ist to create a useful visualisation, which can store lots of information in one place, without having to abstain from a user friendly interface.

=== Dataset Analysis ===
In the following Table, you can find the attributes which should be contained in a MP3 file. These attributes are 1-dimensional. 
A MP3 file contains only attributes with data.

== Target Group Analysis ==

=== Who should use this visualation technique? ===

In the past years media is getting much smaller, much better in quality, and also provide more space for our data. If you convert conventional audio files from CDs to the MP3 Format, you can afford to have your whole music collection on one larger hard drive. The business within the musich industry is taking over the internet. You are either able to download song, or listen to them directly through streams. So your favorite song ist just a click away! 
Because of the fact that this new art of saving your songs, albums and so on, does not contain the usually shipped cd covers which were a very good visualisation of the audio you are listening to, it has become very important to find a good solution for the visualisation of your music archive. 
At this moment the target group are mostly the people who already use the MP3 format to store their audio data, but should expend soon to all the other music-lovers.

=== What are the characteristics of the target group? ===
Like we already mentined (2.1) the business with the music is spreading more and more towards the internet. So over the years there are going to be developed more and more solutions (e.g. for children, elders, amaurotics etc.) for the music market place.
The target group is going to expand over the years.

=== Are there any known / often used Methods / Visualisation Techniques? ===
Das wohlbekannteste und am weitersten verbreitete Programm für mp3 Dateien ist iTunes von Macintosh, nicht zuletzt aufgrund des regelrechten Booms von verkauften Ipods der letzen Jahre. iTunes verwenden zur Verwaltung der Musikbliothek eine XML Datei. In ihr sind die Metainformationen der Audiodateien abgelegt, unabhängig von den Metainformationen der proprietären Audioformate, die zum Beispiel ID3-Tags ablegen. Der Vorteil besteht darin, dass die Metainformationen trotzdem verändert werden können, wenn die Audiodateien das Modifizieren ihrer Tags nicht erlauben. iTunes beinhaltet außerdem einen Visualizer für verschiedene vorbelegte Musikgenres und kann Musik in verschiedenen Audioformaten importieren (enkodieren) sowie abspielen (dekodieren), außer bei gekaufter Musik, die im geschützten AAC-Format gekauft wird.

== Purpose of the Visualisation ==

=== What should be achieved with the Visualisation? ===
informationen sollen übersichtlich und intuitiv dargestellt werden. der user soll sich auf einen blick die zurechtfinden und wissen das es sich hierbei um information eines musik titels handelt.

=== Which tasks should be solved? ===
Es soll möglichst ein Mittelweg gefunden werden das alle User ob jung oder alt viel oder wenig Hörer zufriedengestellt wird. Das Problem an daran ist das Dartstellung oft sehr subjectiv wirken bzw auch sind. Dem einen sind die Dargestellten Informationen zuviel den anderen zu ungenau. Es soll somit ein guter kompromis gefunden und umgesetzt werden

=== Questions that can be solved using this Visualisation ===

* Welcher Titel wird im Moment abgespielt?
* Welche Interpreten sind vorhanden?
* Welche Lieder sind vorhanden?
* Wieviel Rock,POP,etc Lieder sind vorhanden?
* Ist die Farbe gut eingesetzt?
* Sind die Informationen gut überschaubar?

== Designproposal ==

=== Which kinds of Visualisation should be used? ===
* Suchfenster für Genre & Interpret
* Gefilterte Suchergebnisse werden ausgegeben im Informationsfenster
* Anzeige und Auswahlfenster der Genres
* Playerfenster mit aktuell laufendem Lied und Interpreten
* Scrolling list up & down
* Anzeigefenster des Interpreten
* Farbliche Unterscheidung der Liederanzahl durch Intervalle
The detail pannel stays blanc until an artist or song is selected and anfterwards gets filled with all the information.

=== Visual Mapping ===

Die Anzahl der Lieder wird farblich gekennzeichnet, zB blau für 0-500 MP3s

=== Who should use this visualation technique? ===
Datenträger wurden in den letzten Jahren immer kleiner und besser und stellen mehr und mehr Speicherplatz zur Verfügung. In mp3 Format convertiert, passt heutzutage nahe zu jede Musiksammlung auf eine Festplatte. Das Geschäft mit der Musik spielt sich mehr und mehr im Internet, per download oder streaming der lieblings Songs. Da es bei dieser Art von Speicherung kein herkömmliches cover bzw booklet mehr gibt ist wird es immer wichtiger diese Flut an Daten gut verwaltet und visualisert dazustellen. Die Zielgruppe umfasst im moment nur die leute die bereits mp3 zum speichern ihrer Musikstücke verwenden, wird sich aber in einigen jahren auf nahe zu alle Musikliebhaber erweitern

UE-InfoVis0506 0125255: /* References */

== Poor Graphic ==
[[Image:Few04tracking-trends.gif|none|thumb|450px|Tracking the Trends]]

== Drawbacks ==

=== Bad Data-ink ratio ===

There are a couple of elements which are not important or even warping to the graph, like: the background pattern (image), the images showing the development. These just overload the graph, so without them, the graph would be a lot simpler, and clearer.

=== Lie-Factor ===

The Y - Axis should start at zero, and the single graphs should be aligned accending.

The X & Y - Axis is not proportionaly represented.

'''Example I'''

The two points on the average price scale "2.0" and "1.9" are on the same hight. This can not be real.

'''Example II'''

(Chip Speed) The distance between 66 MHz and 1100 MHz is just slightly smaller than between 1100 and 3000 MHz.

=== Chart-Junk ===

The Illustrations are unnecessary, because they are nonserious.

=== Color ===

Using nearly the same color for two different data sources (Units shipped & Chip speed) can be obscuring and misguiding.

=== Incompleteness ===

A clear and understandable legend of the Elements is missing.

The user can't clearly recognise if the chip speed is in MHz or GHz.

The X-Axis should be labeled ("Year").

The structure of the hints for the different stages should be consistent.

== Corrections ==

* The graph should be illustrated a lot simpler, even almost self-explanatory.
* The background pattern should be removed.
* The images(rabbit etc.) are unnecessary and should also be left out in the new version.
* Proportion of the single graphs should be consistent.
* The color of the graphs should differ.
* The axes should be clearly defined.
* The Caption for the graph should be clear and very well understandable.
* The user should be able to see the most important information on the first look.

== Redesigned Graphic ==

UE-InfoVis0506 0125255: /* Incompleteness */

== Poor Graphic ==
[[Image:Few04tracking-trends.gif|none|thumb|450px|Tracking the Trends]]

== Drawbacks ==

=== Bad Data-ink ratio ===

There are a couple of elements which are not important or even warping to the graph, like: the background pattern (image), the images showing the development. These just overload the graph, so without them, the graph would be a lot simpler, and clearer.

=== Lie-Factor ===

The Y - Axis should start at zero, and the single graphs should be aligned accending.

The X & Y - Axis is not proportionaly represented.

'''Example I'''

The two points on the average price scale "2.0" and "1.9" are on the same hight. This can not be real.

'''Example II'''

(Chip Speed) The distance between 66 MHz and 1100 MHz is just slightly smaller than between 1100 and 3000 MHz.

=== Chart-Junk ===

The Illustrations are unnecessary, because they are nonserious.

=== Color ===

Using nearly the same color for two different data sources (Units shipped & Chip speed) can be obscuring and misguiding.

=== Incompleteness ===

A clear and understandable legend of the Elements is missing.

The user can't clearly recognise if the chip speed is in MHz or GHz.

The X-Axis should be labeled ("Year").

The structure of the hints for the different stages should be consistent.

== Correction ==

* The graph should be illustrated a lot simpler, even almost self-explanatory.
* The background pattern should be removed.
* The images(rabbit etc.) are unnecessary and should also be left out in the new version.
* Proportion of the single graphs should be consistent.
* The color of the graphs should differ.
* The axes should be clearly defined.
* The Caption for the graph should be clear and very well understandable.
* The user should be able to see the most important information on the first look.

== Redesigned Graphic ==
