“Certain cultures may prefer particular gestures and we may see a difference, but there is common ground between cultures choosing some gestures for the same kind of purposes and actions,” said Xiaolong “Luke” Zhang, associate professor of information sciences and technology and principal investigator of the study. “So we wanted
