While there are many methods for measuring objective data, capturing and interpreting subjective factors—like the feelings or states of mind of the users—is still an imprecise and usually post-event process. In this paper we propose the utilization of the Emotiv EPOC commercial electroencephalographic (EEG) neuroheadset for real-time support during evaluations and user studies. We show in two evaluation scenarios that the wireless EPOC headsets can be used efficiently for supporting subjectivity measurement. Additionally, we highlight situations that may result in a lower accuracy, as well as explore possible reasons and propose solutions for improving the error rates of the device. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/11283 Künstliche und natürliche Intelligenz Frintrop, S. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/11285 Human-Computer Interaction Ebert, Achim; Gershon, Nahum D.; Veer, Gerrit C. Human-Computer Interaction (HCI) is a term known since the early 1980s. In HCI, the user plays the central role, much more than the computer hardware or software by itself. It is a multi-disciplinary research field, populated by researchers and practitioners from areas like psychology and cognitive sciences, ergonomics, sociology, computer science, graphic design, business, and more. In order to build really usable interfaces, the knowledge and engagement of every single related field are basic prerequisites. We are taking a look on how selected areas have contributed to HCI in recent years. 2012-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/11280 Incorporating Usability Evaluation in Software Development Environments Humayoun, Shah Rukh We propose a way to define and automate user and usability evaluation from within the integrated development environment (IDE). Specifically, for the automatic analysis of usability issues and functionality problems, we provide a framework for conducting evaluation experiments using TaMoGolog-based formal task models. This approach enables the software development team to automatically collect and analyze users and system activities and behavior for recognizing usability issues and functionality problems in an efficient and effective way. The developed tools, UEMan and TaMUlator, provide the realization of the proposed approach and framework at the IDE level. 2012-01-01T00:00:00Z
