The Evaluation of a Physiological Data Visualization Toolkit for UX Practitioners: Challenges and Opportunities

The objective of this paper is to outline the challenges we have encountered during the development and evaluation of our Physiological Data Visualization (UX Heatmap) toolkit and discuss the opportunities that emerged from our experience. The main goal of the Physiological Data Visualization toolkit is to allow simpler and richer interpretation of physiological signals for UI evaluation, in order to reduce the barriers associated with the use of physiological measures in the fields of user experience design and research. Following a user test with 11 UX experts from the industry, we were able to better understand how and in which contexts they would use the proposed UX Heatmap toolkit in their practice.
