TEDxCopenhagen talk: Human Data for Life

On May 17th I was invited to give a TED talk as part of a TEDxCopenhagen Salon Event focusing on technology organized by TEDxCopenhagen and The Danish Society of Engineers (IDA).


The theme of the event was ”Breaking Currents” and the ambiguous wording of the theme inspired me to the ambiguous title of my talk: Human Data for Life.


Videos from the event should be posted within a couple of weeks.

QS Spiral: Visualizing Periodic Quantified Self Data

As part of the Personal Informatics Workshop at CHI2013 we presented our paper QS Spiral: Visualizing Periodic Quantified Self Data. The paper is co-authored with Andrea Cuttone and Sune Lehmann.

In the paper we propose an interactive visualization technique QS Spiral that aims to capture the periodic properties of quantified self data and let the user explore those recurring patterns. The approach is based on time-series data visualized as a spiral structure. The interactivity includes the possibility of varying the time span and the time frame shown, allowing for different levels of detail and the discoverability of repetitive patterns in the data on multiple scales.
