Visualizations

Here you find some of the visualizations I worked on during my internship at the Fraunhofer Institute, at the department of Information Visualization and Visual Analytics.

Work behavior (SWELL-KW dataset)

The data:

The dataset was collected in an experiment, in which 25 people performed typical knowledge work (writing reports, making presentations, reading e-mail, searching for information). We manipulated their working conditions with the stressors: email interruptions and time pressure. A varied set of data was recorded: computer logging, facial expression from camera recordings, body postures from a Kinect 3D sensor and heart rate (variability) and skin conductance from body sensors.

SWELL Subjective Input app

The data:

The data was collected during 8 months with the SWELL Subjective Input App. The user filled in his experienced Energy level, Valence and Calmness/Stress:

SWELL Personal Feedback Tool

The data:

The data was collected during office days for about a year. Computer data was logged (amount of keystrokes, clicks and application switches) and the user annotated this data with the energy level that he or she experienced:
