The ACM CHI conference is the premier publication venue in the field of HCI, and Scotland-based researchers are contributing extensively to the programme for the 2026 conference which will be held in Barcelona, Spain in mid-April. The Pre-CHI Day is a chance for the Scottish HCI community to see some of the world-leading research going on across Scotland, and allow those not travelling to Spain to talk to authors first-hand and hear about their work. The event will be hybrid, and virtual attendance and virtual presentation will both be supported. We expect a mixed audience, including researchers of the Scottish HCI community as well as interested students, designers, industry, practitioners etc., as well as newcomers to the field of HCI.
