Andreas M. Klein is a lecturer and research assistant in the Faculty of Technology at the University of Applied Sciences Emden-Leer, Germany, and holds a diploma in Electrical Engineering and a Master of Engineering in Technical Management. He is a Ph.D. candidate in the Department of Computer Languages and Systems at the University of Seville, Spain, since 2020. The research focus of the dissertation is the investigation of voice assistant systems.
Voice User Interfaces (VUIs) are becoming increasingly available while users raise, e.g., concerns about privacy issues. User Experience (UX) helps in the design and evaluation of VUIs with focus on the user. Knowledge of the relevant UX aspects for VUIs is needed to understand the user’s point of view when developing such systems. Known UX aspects...
Virtuellen digitalen Assistenten (VAs) wird weltweit ein enormes Wachstum bei Unternehmensanwendungen vorausgesagt. Eine Form von VAs sind Sprachassistenten, welche in vielen Geräten und Systemen integriert sind (z.B. Smartphones). VA-Qualitätskriterien, wie korrekte Befehlsausführung, Sprachverständlichkeit und der Datenschutz, sind gleichzeitig H...
Currently, voice assistants (VAs) are trendy and highly available. The VA adoption rate of internet users differs among European countries and also in the global view. Due to speech intelligibility and privacy concerns, using VAs is challenging. Additionally, user experience (UX) assessment methods and VA improvement possibilities are still missing...
Protocol for Comparing Voice Assistant Risks and Potential with Technology-Based Users: A Study from Germany and Spain. Version 3.0 / 2021.
Voice user interfaces (VUI) are currently a trending topic but the ability to measure and improve the user experience (UX) is still missing. We aim to develop a tool selector as a web application that can provide a suitable tool to measure UX quality of VUIs. The UX tool selector for VUIs will include a UX measurement toolbox containing several exi...

Voice user interfaces (VUIs) or voice assistants (VAs) such as Google Home or Google Assistant (Google), Cortana (Mircosoft), Siri (Apple) or Alexa (Amazon) are highly available in the consumer sector and present a smart home trend. Still, the acceptance seems to be culture-dependent, while the syntax of communication poses a challenge. So, there a...
Protocol for Exploring Voice Assistant Risks and Potential With Technology-based Users Version 2.0 / 2020
The UEQ+ is a modular framework for the construction of UX questionnaires. The researcher can pick those scales that fit his or her research question from a list of 16 available UX scales. Currently, no UEQ+ scales are available to allow measuring the quality of voice interactions. Given that this type of interaction is increasingly essential for t...
Klein, A. M., Hinderks, A. Schrepp, M. and Thomaschewski, J., (2020) describe the construction of three scales to measure UX aspects specific to voice systems and how these can be used in the UEQ+ framework (Schrepp & Thomaschewski, 2019) to measure UX of such systems. This research report gives detailed information about data analysis done for VUI...
How to solve social issues with computer science techniques Together with my colleagues, we have a bigger picture which is presented in our Reserach Group on: https://www.researchgate.net/lab/Research-Group-for-Agile-Software-Development-and-User-Experience-Joerg-Thomaschewski Here we have current Rearch from my active members: Andreas M. Klein, Kristina Kölln and Anna Weigand.
The quality assurance of the software is a line of work that has been developing for many years but that every day acquires more importance because the Information and communication Technologies (ICT) are increasingly present in our lives . Nowadays, if a software wants to be competitive, it has to cover in the most efficient way possible all the requirements that users demand and it has to guarantee, in addition, a robustness and consistency of the data they handle. The SiTPGa project aims to find mechanisms that guarantee the quality of software products from the earliest stages of the life cycle. The research carried out has three main work focuses: (1) Software testing, which pilots early tests on both functional and non-functional requirements as well as data testing. (2) The effective inclusion of the user in the earliest stages of the software and very specifically in the business process environment in order to correctly define the flexibility, adaptability and possible robotization thereof (RPA-Robotic Process Automation) (3) Gamification, developing solutions aimed at improving the skills of stakeholders to make the production of quality software more effective. The project consists of three subprojects led by the University of Seville, the University of Oviedo and the University of Cádiz in which staff from 22 different organizations participate and have the support of 33 entities interested in the results of the project as well as with the collaboration of 13 international doctors of high prestige. A high scientific-technological impact of the same is foreseen as well as a notable social impact since it is oriented towards the challenges of society and more specifically that of Economy and Digital Society.
