Matthias Heintz

Research Associate


Matthias Heintz is a research associate at the Department of Computer Science of the University of Leicester (UK). He obtained his Diploma and Master’s degree in Computer Science in Media from the Furtwangen University of Applied Sciences-Computer Science, Engineering, Business, Media in Germany. Before joining the University of Leicester he worked at the Fraunhofer Institute for Experimental Software Engineering (IESE) in Kaiserslautern, Germany on various research and industrial projects regarding i.a. user interface design and evaluation, education, and mobile software engineering. His research interests are human-computer interaction (HCI), Participatory Design (PD), and technology-enhanced learning (TEL) with a focus on usability and user-experience (UX) in general and end-user involvement in particular.


Currently I am a Teaching Fellow in Informatics, working for the ARETE project during my research time.

Previously I was a Research Associate for the Next-Lab project, continuing my work from the Go-Lab project, and for the C3AOL project.

In conjunction with my PhD work I was working in the Go-Lab project supporting the evaluation of webapps and online lessons with students and teachers. As part of this work I developed a tool to support these evaluations called PDot (Participatory Design online tool). My current research focus is how this tool compares to the traditional paper-based Participatory Design approaches and how it can support researchers to analyse and developers to work with the user feedback gathered. In case you would be interested to try out the tool for yourself, please just drop me an email.

PDot is an online tool that allows users to give feedback on prototypes of various maturity level and webapps in participatory design workshops or more general usability and user experience evaluations. Its main feature for end users is to provide instructions on how to evaluate the prototype, creating an overlay on top of the prototype enabling graphical feedback and providing additional means to give feedback (ranging from textual comments to specifying your mood). Its main feature for researchers is to pre-process the feedback and present it in an aggregated way to support the data analysis task.
