World Usability Day is a single day of events occurring around the world that brings together communities of professional, industrial, educational, citizen, and government groups for our common objective: to ensure that the services and products important to life are easier to access and simpler to use. The Design Challenge Awards (Gold $1,250; Silver $1,000; and Bronze $750) are sponsored by the HCII2023 Conference and will be conferred during the opening plenary session (evening of the 25th of July). The three award recipients are invited, with complimentary registration, to present their work in a special session during the (hybrid) conference.
