Am 28. September 2018 hat Johannes Schobel seine kumulative Dissertationsschrift mit dem Titel

A Model-Driven Framework for Enabling Flexible and Robust Mobile Data Collection Applications

erfolgreich an der Universität Ulm verteidigt. Das DBIS-Team gratuliert Johannes herzlich zur Erlangung des Doktortitels der Naturwissenschaften (Dr. rer. nat.). Johannes wird vorerst als Postdoktorand am Institut weiter wirken, wofür DBIS ihm viel Erfolg und alles Gute wünscht. Doktorvater von Johannes ist  Prof. Dr. Manfred Reichert, der mit Dr. Rüdiger Pryss die Doktorarbeit gemeinsam betreut hatte. Externer Gutachter ist PD Dr. Winfried Schlee (Universität Regensburg). Seine Forschungsarbeiten hat Johannes im Kontext des Projektes QuestionSys durchgeführt, das die Entwicklung mobiler Apps zur Umsetzung sog. Instrumente durch Domänenexperten zum Ziel hat.

Kurzzusammenfassung (in englischer Sprache):

In the light of the ubiquitous digital transformation, smart mobile technology has become a salient factor for enabling large-scale data collection scenarios. Structured instruments (e.g., questionnaires) are frequently used to collect data in various application domains, like healthcare, psychology, and social sciences. In current practice, instruments are usually distributed and filled out in a paper-based fashion (e.g., paper-and-pencil questionnaires). The widespread use of smart mobile devices, like smartphones or tablets, offers promising perspectives for the controlled collection of accurate data in high quality. The design, implementation and deployment of mobile data collection applications, however, is a challenging endeavor. First, various mobile operating systems need to be properly supported, taking their short release cycles into account. Second, domain-specific peculiarities need to be flexibly aligned with mobile application development. Third, domain-specific usability guidelines need to be obeyed. Altogether, these challenges turn both programming and maintaining of mobile data collection applications into a costly, time-consuming, and error-prone endeavor. The Ph.D. thesis at hand presents an advanced framework that shall enable domain experts to transform paper-based instruments to mobile data collection applications. The latter, in turn, can then be deployed to and executed on heterogeneous smart mobile devices. In particular, the framework shall empower domain experts (i.e., end-users) to flexibly design and create robust mobile data collection applications on their own; i.e., without need to involve IT experts or mobile application developers. As major benefit, the framework enables the development of sophisticated mobile data collection applications by orders of magnitude faster compared to current approaches, and relieves domain experts from manual tasks like, for example, digitizing and analyzing the collected data.
