In the first, theoretical work (Vieten & Weich, 2020), the individual kinematic components of human motion are described. In addition to the movement itself, these include various "deviations" and "disturbing factors", which we usually unconsciously controlled in everyday life and during sports. Thus no step is ever the same as the previous one.

This was followed by another publication (Weich, Vieten & Jensen, 2020), which deepens a partial aspect of the first work, the so-called transient effect. Many athletes report that at the beginning of a running session the running style feels very uneven for a few minutes until they have literally "found their rhythm". We were able to show that in most (approx. 80%) of our measured runners, such a " transient" or "finding the rhythm“ - phase can actually be displayed with data.

The third work (Weich & Vieten, 2020b) was a complete application study based on the idea that when a known person approaches you from a distance, you can often tell who it is by the movement/walking style without having noticed their face or voice. Is there such a thing as an individual walking style by which you can be identified definitively? This has been called gaitprint, referring to a fingerprint. Here we found a recognition rate of over 99%, i.e. only 1 of 100 people would not have recognized by our algorithm correctly!
