A Design Model for Tangible Interaction: Case Study in Waste Sorting

In this paper, we propose a design model for applications with Tangible User Interfaces (TUI). This model aims to support designers in organizing the different elements and their relationships. We then implement the model through the design of a Serious Game for an RFID tabletop that uses tangible objects: this Serious Game simulates microbiological waste sorting in a practical educational setting. In this case study, a scenario is described, highlighting the use of the design model. The conclusions and suggestions for future research are then presented.
