“…During the whole test psycho physiological measures of EEG, SCL and HR were recorded. In L1 and L2 additional videos and screen recordings were made (examples can be seen in [8]. In the control condition, the test persons were asked to relax in order to get some base data.…”

Abstract. Emotion is an important mental and physiological state, influencing cognition, perception, learning, communication, decision making, etc. It is considered as a definitive important aspect of user experience (UX), although at least well developed and most of all lacking experimental evidence. This paper deals with an application for emotion detection in usability testing of software. It describes the approach to utilize the valence arousal space for emotion modeling in a formal experiment. Our study revealed correlations between low performance and negative emotional states. Reliable emotion detection in usability tests will help to prevent negative emotions and attitudes in the final products. This can be a great advantage to enhance Universal Access.

“…The use of biometrics in a usability context has been demonstrated by several previous work, e.g. [5], [6], [7], [8]. To meet the pragmatic and hedonic goals, which are related to the overall experience and results of human-computer interaction, we speak about User Experience (UX).…”

“…One of the few existing studies conducted by Andrzejczak and Liu (2010) compared the effect of the test location (lab vs. remote) on user anxiety, finding no meaningful differences. Some authors explored the use of biological and psycho-physiological measures in usability testing to detect arousal (Stickel et al, 2008, Lin et al, 2005. However, to our knowledge, the experimental use of stressors has not been investigated systematically so far.…”

In this study we investigated whether the experience of stressors would influence the performance of users in usability tests as well as their subjective rating of the usability of an interactive system. To that end, an experimental study was conducted comparing a usability test that was performed in the lab under quiet, relaxed conditions with a test situation where several stressors (time pressure, noise, social pressure) were applied. Results show that participants in the stress condition did considerably worse regarding the completion and correctness of the tasks. The stress and negative feelings the participants experienced also influenced their view of the tested software. Participants in the stress condition rated the usability of the software and their user experience considerably more negative. Implications for the practice of usability testing are discussed.

This paper provides a high-level overview of the field of usability evaluation as context for a panel "Systematization, Modeling and Quantitative Evaluation of Human Interface" in which several authors report on a collaborative effort to apply CogTool, an automated usability evaluation method, to mobile phone interfaces and to assess whether usability predictions made by CogTool correlate with user subjective impressions of usability. If the endeavor, which is still underway at the time of writing, is successful, then CogTool may be applied economically within the product development lifecycle to reduce the risk of usability problems.
