Visualisation of UX Data

A tool for the playful approach to UX Data

In this talk we present InteracDiff, a visualisation tool that helps addressing the challenge of interpreting and understanding UX data after testing and evaluation sessions.

To steadily improve experiences, UX research, testing and design iterations are mandatory. These tests can, for example, include questionnaires which provide data to measure the product’s hedonic and pragmatic qualities. Mostly, the gathered data is presented here in a scientific format (mean value diagrams) which makes it difficult for people outside the scientific community (e.g. product managers, marketing managers, CEOs) to understand benefits, limitations and challenges for further improvement of a digital service or product. Based on our long time professional experiences gained in the industry our tool InteracDiff has the potential to improve current commercial UX practice when presenting data to clients. In this talk we present our interactive tool along with study results that indicate the need for more playful and engaging ways to digest collected UX data. Participants of the UX Day can befit form the talk and get inspirations on how to deal with similar domain specific challenges in their work and see how our tool was developed and implemented.
