"For a decade or more, museums and other cultural institutions have increasingly focused on two key ideas in relation to educating their audiences, which is one of their core functions. Visiting a museum is often, if not predominantly, a social outing. We attend with our families and friends or even with other strangers as part of a docent tour, for example. And different people learn in different ways. Some learn best by looking, some prefer reading labels, and others learn by doing. This is admittedly a simplification, but the idea of what is now called the Dialog table is to use the affordances and meanings associated with tables in conjunction with the flexibility and responsiveness of computer-based information systems. The table "delivers" rewarding and compelling experiences in a manner that is easily graspable, responsive to personal learning styles, and encouraging to social interactions." (Steve Dietz; "A Monologue about Dialog", in Expanding the Center: Walker Art Center and Herzog & de Meuron, Minneapolis: Walker Art Center, 2005), 154.)
