User-system trust relationship plays a crucial role in supporting the effectiveness of visual analytics (VA) tools, such as guidance. Trust undergoes rapid variability in systems that deal with high uncertainty factors, such as data uncertainties and visualization literacy [1]. Designers tune their decisions to boost and maintain user trust in the system and tools. Detecting trust in users' attitudes and its variability through the analysis session can be challenging [2]. The literature demonstrates work to analyze user trust in the evaluation phase of the project. However, a real-time detection and analysis of trust is needed to calibrate visualization tools for the user and the analysis contexts [3,4,5,6]. We are interested in investigating and developing an approach to analyze trust objects and issues, i.e., a model to formalize user trust externalization [7], and methods of trust expression. We aim to use the results to support the design of VA tools and approaches such as explainability techniques [8,9].


In this project, you will be tasked with conducting a thorough literature investigation of trust and developing a model of formalizing and externalizing trust that can be generalized across multiple fields of visualization. You will develop a framework to demonstrate the applicability of your model.


  • Knowledge of English language (source code comments and final report should be in English)
  • Knowledge of Python or comparable programming languages is advantageous
  • Interest in the intersection of visualization with psychosocial topics


The project should be implemented as a standalone application, desktop or web-based (to be discussed).
