01
Set the footprint
Mark and test the operating footprint. Use a compact marked spot away from book displays, signing tables, drinks, queue lines, and accessible routes. For this exact themed in-store event, protect browsing, author access, reading volume, and low-noise use; BubbleMatch is first because its profile keeps the play area contained.
02
Open the round
Rehearse the exact opening moment. At the themed in-store event, the bookseller starts with BubbleMatch because readings and signings leave younger attendees waiting between formal moments. The host connects the color-and-timing challenge to the story theme, runs one bounded turn, and hands the station to the next participant without interrupting the formal program.
03
Guide the rotation
Assign and rehearse the operator sequence. For the themed in-store event, the bookseller checks the camera mark, explains BubbleMatch's simple visual response, invites one voluntary turn, resets the result, and offers GestureChess when readers need a quieter seated option.
04
Close or change course
Brief privacy and contingency choices before opening. Keep camera play separate from mailing-list signup, purchase records, author photography, and event recording. Before the first BubbleMatch turn, explain the webcam interaction, ask before capturing or sharing any participant image, and keep opt-out participation available for bookstore event teams. At the themed in-store event, if a reading, signing, queue, or quiet browsing moment needs the footprint, pause or close the station; otherwise move from BubbleMatch to GestureChess without widening the marked zone.
