摘要

To address shortcomings of predominately subjective measures in empirical IS research on IT usage and human-computer interaction, this paper uses a multi-method experimental analysis extending empirical surveying with objective measures from eye-tracking and electrodermal activity (EDA). In a three stage process, objective user performance is observed in terms of task fulfillment and user performing of participants in four focus groups, classified by user system experience and the treatment pressure to perform. Initial results of this research-in-progress reveal that users with prior system experience perform considerably better and faster than users without system experience. This also accounts for users under pressure to perform compared to users without pressure to perform. However, the results of the EDA show that users under pressure to perform also have a higher objective strain level. Furthermore, a first regression analysis outlines that objective performance might help to understand user's system satisfaction to a greater extent.
