Other Titles: | Mobile Usability TestingA toolbased Framework for Rapid-Prototyping and Usability-Testing of Mobile Systems within the native Context of Use | Authors: | Krannich, Dennis | Supervisor: | Schelhowe, Heidi | 1. Expert: | Schelhowe, Heidi | Experts: | Friedrich, Jürgen | Abstract: | Mobile systems are indispensable in our daily life. Therefore eà °ective processes are necessary, in order to cope with the increased requirements by the end users and the high cost- and time- pressure. Whereas usability-testing is mostly standardized for stationary systems, mobile systems face new challenges according to their heterogeneity. This dissertation seeks to improve the de- sign and development in order to provide intuitive and innovative mobile systems by strengthen- ing the consideration of the user's requirements as well as the context of use within early stages of the design process. The core contribution is the development and evaluation of a tool-based process-model consisting of a phase-model and an rapid-prototyping- and usability-testing- instrument. It enables a) to develop prototypes and perform usability-tests in early product stages, b) usability-testing within the native context of use and on real devices, and c) to collect valuable data. Additional features are remote observation and simulation in terms of the Wizard-of-Oz- method. The empirical studies confirmed the concept of the tool-based process-model and showed a close connection between rapid-prototyping and usability-testing. |
