Highlights from the Detroit SID Vehicle Display Symposium and Exposition

THE DETROIT METRO CHAPTER OF SOCIETY FOR INFORMATION Display (SID) held its 29th Annual Vehicle Displays and Interfaces Symposium Exposition (VDS) as an in-person event September 27 28 in Novi, Michigan. While not completely returning to pre-pandemic levels, VDS 2022 had 539 registered attendees 51 exhibitors. The annual symposium is designed disseminate information among designers, engineers, scientists, technologists, researchers, system integrators of land, air, sea, space vehicle displays display components. conference has become a primary venue for exchange experts the automotive industry. “We are pleased report that this year, paper submissions increased by 45 percent exhibits 29 percent,” said Silviu Pala, chair VDS. “The main objective provide forum original equipment manufacturers (AOEM), industry, academia. Participants opportunity review debate topics related interfaces. We were excited present so many innovations, particularly areas head-up new solutions both auto interiors exteriors.” event's popular automotive-focused market session was chaired Pala Michael Boyd from Yazaki North America. Expert analysts included Brian Rhodes S&P Global (formerly IHSMarkit), Jennifer Colegrove Touch Research, Bob O'Brien Supply Chain Consultants (DSCC), You Xiang Wu Omdia Research. There also exhibition featuring companies with block time dedicated exhibitor presentations. Each year at VDS, Detroit Metro chapter presents Academic Awards graduate students performing research into technology (Fig. 1).

In describing issues design, Poliak drew inspiration art world, “vehicle canvas.” When discussing goal user experience (UX) he said, “Activate contextually relevant when needed, exclude what's needed.” reviewed aspects UX including only flat-panel inside vehicle, but augmented reality (AR-HUDs) even exterior 2).
