We have finalized the call for papers for the fifth EuroRV³, which will again be held in conjunction with EuroVis, this year in Barcelona, Spain, June 12-13, 2017. This year’s workshop concentrates on perceptual evaluation of visualization and is subtitled “Perception in Visualization”. We solicit short papers, which will be peer-reviewed in a one-stage process and electronically published in the Eurographics Digital Library. Submission deadline is February 17th, 2016.
