QoE Alchemy 2.0: An improved test setup for the pecuniary bias of QoE

Examining monetary aspects related to QoE research, e.g. as bias, requires specifically defined empirical testing and data analysis routines. This paper presents an advanced setup for investigating the impact of purchasing behaviors in an interactive Video-on-demand scenario, and, based on lessons learned from previous and current experiments, provides a set of recommendations for further research in this direction.
