A tool for measuring and optimizing UX factors important for the adoption of PETs.

For users, the interface of a technology is the technology. The acceptance, usage and success of privacy-enhancing technologies (PET) depend on the experience of the users: Can the PET increase the feeling of reliability, confidentiality, integrity, security, trust and privacy?

To answer this question and in order to optimize the user experience (UX) through changes in the user interface that enable a usable and accessible application, developers need to be able to measure these UX-Factors: Reliability, confidentiality, integrity, security, trust and privacy.

Until now there are no UX measurement instruments fitting for PETs. We want to change that and develop a PET-UX-measurement tool. This tool will be available as an easy-to-use web application with its code open-sourced and can be used by developers of PETs to test and increase the UX of their applications. It is based on psychometric approaches for measuring subjective feelings of users and is powered by machine learning.

Why PET developers should use a PET-UX tool to measure and optimize the UX of their applications.

1. Developers have an idea for a new PET or they want to measure an already existing one.

2. The new measuring tool can be used in tests with potential users to measure the UX.

3. A good user experience (UX) helps users to better understand the principle and features of PETs.

We merge psychometric approaches for measuring subjective feelings of users and machine learning to develop a tool that enables PET developers to better understand the user’s perspective and on the other side helps users to better understand the importance of privacy enhancing technologies.
