As the outcome of the Dagstuhl Seminar 15481 on Crowdsourcing and Human-Centered Experiments
this book is a primer for computer science researchers who intend to use crowdsourcing
technology for human centered experiments. The focus of this Dagstuhl seminar held in Dagstuhl
Castle in November 2015 was to discuss experiences and methodological considerations when
using crowdsourcing platforms to run human-centered experiments to test the effectiveness of
visual representations. The inspiring Dagstuhl atmosphere fostered discussions and brought
together researchers from different research directions. The papers provide information on
crowdsourcing technology and experimental methodologies comparisons between crowdsourcing and
lab experiments the use of crowdsourcing for visualisation psychology QoE and HCI empirical
studies and finally the nature of crowdworkers and their work their motivation and
demographic background as well as the relationships among people forming the crowdsourcing
community.
