Trans-surface interaction addresses moving information objects across multi-display environments that support sensory interaction modalities such as touch, pen, and free-air. Embodiment means using spatial relationships among surfaces and human bodies to facilitate users' understanding of interaction. In the present embodied trans-surface interaction technique, a peripheral NFC tag array provides tangible affordances for connecting mobile devices to positions on a collaborative surface. Touching a tag initiates a trans-surface portal. Each portal visually associates a mobile device and its user with a place on the collaborative surface. The portal's manifestation at the top of the mobile device supports `flicking over' interaction, like playing cards. The technique is simple, inexpensive, reliable, scalable, and generally applicable for co-located collaboration. We developed a co-located collaborative rich information prototype to demonstrate the embodied trans-surface interaction technique and support imagining and planning tasks.
