A smart desk and barricade provide ad-hoc protection during emergencies and an augmented presentation environment. A first desk tabletop includes a connection positioned on an underside of the first desk tabletop, that is configured for detachable coupling to a desk frame. Removal of the tabletop from the desk frame provides a shield. An interlocking element is positioned on one or more edges of the first desk tabletop. The interlocking element is configured to temporarily connect to an edge of a second desk tabletop. A temporary attachment of the first desk tabletop to the second desk tabletop forms a barricade system. In some embodiments, a computing device is integrated into the desk tabletop. A smart room environment may network the desk with integrated computing device to other computing devices in the room.
