Plan D proposes outfitting a conference room with high-tech interactive and audiovisual equipment like an 86-inch 4K interactive board, automatic smart glass walls, wireless speakers and projector, and remote-controlled curtains and blinds to enhance meetings. Additional suggestions include air purifiers, room fresheners, soundproofing, an automatic pop-up table box, a uniquely shaped table for all attendees to see each other, and self-parking chairs to keep the space tidy.
