Aufgabenstellung
Gegebene Daten
Homer Simpson's Trinkverhalten in Abhängigkeit von seinen Lebensumständen
...Visualisierung von Homer's Lebensabschnitten bzw. Ereignissen mit Einfluss auf sein
Trinkverhalten (zB.: Kindheit, Pubertät, Arbeitslosigkeit, Beziehungen, Hochzeit, Geburt
der Kinder, Liebeskummer, Alltag, etc.) von seiner Geburt bis Jetzt + mögliche
Zukunftsszenarien (mind. 3).
- Die Menge folgender Getränke soll für die jeweiligen Lebensumstände ablesbar sein
(ml oder Liter - je nachdem - pro Tag, Monat, Jahr (z.B.: Fokus+Kontext Methoden):
a) Wasser
b) Milch
c) Fruchtsaft
d) Cola
e) Kaffee (Würfelzucker?)
f) Bier
(vereinfacht angenommen, Homer trinkt ausschließlich diese Getränke)
- Die folgenden Werte sollen abhängig von den konsumierten Getränken ablesbar sein:
1) g oder kg konsumierter Zucker (aus Getränken) + empfohlene Maximaldosis pro Tag, Monat, Jahr (empfohlene Maximaldosis/Tag: 50g; enthaltener Zucker: 10g/100 ml Cola; 10g/100 ml Fruchtsaft; 3g/Würfelzucker).
2) mg konsumiertes Coffein + empfohlene Maximaldosis pro Tag, Monat, Jahr (empfohlene Maximaldosis/Tag: 600mg; enthaltenes Coffein: 10 mg/100 ml Cola; 80 mg/100 ml Kaffee).
3) g konsumierter Alkohol + empfohlene Maximaldosis pro Tag, Monat, Jahr (empfohlene Maximaldosis/Tag: 20g; enthaltener Alkohol: 3,6 g/100ml Bier)
- Die Daten sollen zur medizinischen/psychologischen Analyse visualisiert werden.
- Die bisher erlernten Design-Prinzipien sollen umgesetzt werden (z.B.: Optimierung der Data-ink ratio).
- Die Mockups sollten zumindest 1) Homer's Leben im Überblick 2) und eine Detailansicht wiedergeben.
- Alle nicht angeführten Daten können frei erfunden werden.
Description
Concept
- Visualization
We should use graphs, when the message is contained in the shape of the values and the document you produce will be used to reveal relationship among multiple values[Few, 2004]. In our task about Homer Simpson's Drinking are too much different values that have to be shown, that a table all alone wouldn't show the information clearly enough.
- Visual Mapping
We seperate the two different viewings for medicinial and psycholigic interests:
On the psychologic or "drink"-view of our data, where the Drinks are selected to be shown:
The different life-periodes are mapped on the x-axis and the liters on the y-axis.
On the medicinial or "substance"-view, where the sugar-, coffein- and alcohol-content can be seen:
The different life-periodes are shown on the x-axis.
The percent, in relation to the recommended maximum dose (=100%) of different substances in the drinks per day, is mapped on the y-axis.
- Description of the technologies
We use a bar diagram to show our nominal dataset, because a simple comparison of the categorical subdivision of one or more measures in no particular order can be shown very easy by this visualization[Few, 2004].
On the "substance"-view, we decided to show (for the medicine view) the differences to the maximal dosis by mapping the substances on a percent-scale, where the maximal dosis is shown by a line[Few, 2004]. The bars show the plus or minus of the substances in Homer Simpson's drinking to these lines.
- Interaction
The user can use between the two views by clicking on the arrows between the two selection windows, where the different drinks and the different substances can be selected. He can select one or more drinks/substances, which will be shown on the diagram.
In the "drinks"-view by selecting a bar he can see a label, where the content of substances will be shown and their recommended maximum dose.
So in the substances-view the liters of the drink and the g, mg and ml are popped-up in a label, when the bar is selected.
The selection of the different views is made for the different viewers and interests.
- MockUp
Figure1=drinks-view with selected bar
Figure 1 shows the different drinks in the different life periodes, so it is made for the physiological interest on the relation between the drinking habits and the time of his life.
Figure2=substance-view with selected bar
Figure 2 is made for the medicinical interest on the deviation to the recommended maximum dose.
Additionally we think about an drag-and-drop- and copy-option for the different-life-periodes, because maybe Homer has more than one time lovesickness. Also more than the given drinks could be added.
