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.
