Module Theme

The theme of this module is aligned with the overall theme of the fall semester 2017: instability. We interpret the term instability in the context of this course as an antonym to stability and the students are asked to look for stability, instability, or the dynamic between these two terms in data sets covering the world around us. Tectonic instability leading to earthquakes, job instability leading to fluctuating jobless rates, economic instability leading to financial crises, political instability leading to democratic overhaul, are just some of the potential examples.

Module Sessions

Input Lectures
Presentations will introduce the students to the essential theory and practice of data literacy and data visualization. These lectures will be divided into design- and technology-oriented inputs. Joël Gähwiler will provide the technology inputs, Benjamin Wiederkehr will provide the design inputs.

Group Mentoring
Individual review and coaching sessions where the instructors give advice to groups of students.

Subject and Objectives

Subject Overview

Many aspects of society, science, business, finance, journalism, and everyday human activity, become ever more quantified. As a result, our world is awash with data of increasing amount and complexity. Still, we must keep afloat with our innate human abilities and limitations. For designers in this environment, working confidently with data becomes an essential skill. Visualization is one way to tame this information overload: well-designed representations replace difficult cognitive calculations with simpler perceptual interpretations. They can thus improve accessibility, comprehension, and memory. More literally, visualization is the process of transforming data into visuals like charts, graphs, and maps. These are then used to explore, evaluate and explain insights hidden in the data. The goal being to engage and aid diverse audiences in analytical sense and decision making.

Student Objectives

This course provides students with an introduction into the theory and practice of designing with data while keeping the human in mind. They learn the basics for creating effective data visualizations. This includes principles from graphic design, human-computer interaction, perceptual psychology, cognitive science, and statistics. We touch on the topics of data literacy, visual perception, graphical encoding, visualization types, color, interaction, animation, exploration, and explanation. In a practical assignment, students apply the techniques, tools, and technologies to design and develop interactive visualizations. After this course, students will be able to turn a data source into a useful, truthful, and beautiful data experience — tailored to specific information needs or communication goals.

Module Outline

The module is split into three parts:

Week 1: Data Literacy
Students learn the basics of data acquisition, formatting, and data conversions. They get to know a wide variety of data sources.

Week 2: Reading Week
Students conduct personal research, read articles, watch videos, and listen to podcasts relevant to the topic of data visualization.

Week 3 – 5: Data Visualization
Students learn and apply the basics of data visualization within a group assignment to build their own interactive visualization.

Assignment

1. In the first phase, the discovery phase, the students explore indicators of instability in the world around us. Such indicators can be found in economics, politics, or finances, but also in social diversity or climate phenomena. The students will research data sets which hold the potential to describe or even explain this instability.
2. In the second phase, the definition phase, the students will conduct a visual analysis of the selected data sets to find their key insight. This can include visualizing different facets of a data set, visualizing a data set with different graphical methods, or putting different data sets in relation to each other. The students will define a question which they can answer using the right data set and the right visualization technique.
3. In the third phase, the development phase, the students design and develop their visualization into a final visual artifact. This is either a graphical poster (minimum requirement) or an interactive prototype (advanced requirement). Depending on the student composition and the intended reader / user experience, the priority between these two artifacts can be defined for each group individually.
4. In the fourth phase, the delivery phase, the students will exhibit and present their work to the rest of the class. Besides the final result, we’re interested in the overall development process from interest to question to answer. These stages should be documented as a visual journal including sketches, mockups, and prototypes.

Deliverables

• Graphical Poster and Interactive Prototype

• Documentation as PDF

• Documentation for the web (text, images, videos)

Graphical Poster

We expect all groups to deliver and present at least a static data visualization of an appropriately sized data set which is relevant to the overarching topic of instability. The visualization should make the data set accessible to people not familiar with the subject matter and highlight important aspects like trends, patterns, or outliers. The poster should include, but is not limited to, the following content: Title, subtitle, introduction, visualization with scales, legends, and annotations, as well as methodology, sources, credits. Format: A3 Portrait

Interactive Prototype

More advanced groups are asked to deliver a prototype of an interactive version of the visualization represented on the poster. The prototype should illustrate the intended functionality in terms of interaction and animation. The prototype can be built using any of, but not limited to, the following tools and technologies: InVision, Principle, Adobe After Effects, Adobe Animate, HTML, CSS, JS, etc. Format: Clickable Prototype
