Conference Website

Overview

Graphics Interface is the oldest continuously-scheduled conference in computer graphics and human-computer interaction. The conference dates back to 1969, when it was the “Canadian Man-Computer Communications Seminar”, changing its name in 1982 to Graphics Interface. Graphics Interface 2021 was the conference’s 47th year, and took place from May 27th – 28th, 2021. This virtual event was free to all to attend with a selection of high quality papers in computer graphics, visualization, and human-computer interaction. Paper presentations were pre-recorded and available on the Graphics Interface YouTube channel and are linked from the Graphics Interface archive.
