abstract data viz

visualizing emotions

I was part of this workshop during the seminar week at the hfg. It ran for five days and was supervised by Anna Wiederkehr, an american designer with a background in journalism, interface and visualization design.

perception of cold
In this design process, a system was developed that visually represents the perception of a person on the subject of cold. The data for the implementation were collected through a survey and was evaluated later. Various attributes such as the size, number of saturations and position of a form were used to encode the variables surveyed.

questions and research
Do people have different sensations of coldness and weakness? Where does a person freeze first? What happens in the body when it freezes? Effects How is cold perceived? What is cold?

The sense of temperature of living beings is called thermoreception. Receptor cells in the skin or mucous membranes serve as corresponding receptors. They generate nerve impulses whose frequency and temporal patterns change depending on the temperature. These impulses are transmitted via the nerve fibres and several neuronal switching points to the brain. Thermoreceptors form the basis of temperature perception.

If the body freezes, it increases the body temperature. The blood circulation is concentrated on the vital organs. In addition, less blood flows through hands and feet, so they cool down first. The skin becomes paler as the blood vessels in the skin contract. The muscles begin to tremble and thus generate heat for the body. Three factors also influence the perception of cold: fat, muscles and height.
- Fat insulates the body and therefore less heat can escape.
- Muscles are also called the body's heat factory, because 80% of the heat is produced by muscles and organs.
- A tall person loses less heat because she/he has a small body surface in relation to her/his body volume. For a smaller person, it's the other way around.

In order to show the different resistance against cold and the general perception of various people I created a questionnaire. By the participation of 12 persons I received a well filled data set, which I evaluated and developed a concept to create a data visualization from it.

here do you find the questionnaire and its evaluation

These are a few ideas that led to the final solution.

final solution
I focused more on to visualize every participant in a seperate vizualization, i think its a good way to show the different variables and characteristics of the individual persons, it is also possible to compare the visualizations quickly. The shape of the variables are squares and rectangles because they convey the values i want to show best. The hard corners and straight edges point a very expressive and strong optical feeling and i think that fits perfectly to the meaning of cold.
