This document discusses teaching tangible interaction design. It emphasizes defining all terms used, specifying contrasts, studying materials, thinking in metaphors, designing expressions, and finding contrasts using Laban Movement Analysis. Examples are provided of student projects that focus on expression of tangibility, beauty of materials, quality of form and movement in interaction, and innovative usage of emerging technologies. The document advocates for an interaction design framework that gives equal importance to function, interaction, expression, form, material, idea, task, and movement. Collaboration on projects is presented as a way to apply these concepts.
