The recognition of facial expressions has an important role in the communication and interaction between human beings. Researches attest that it is possible to exercise the recognition skills and production of facial expressions with the aid of computational support tools. This article presents Trimemória, a game whose objective to produce a therapeutic playful environment for children with difficulty in recognizing facial expressions. Trimemória seeks to apply classic dynamics of memory games with sensors, in an attempt to increase the integration of the real world with the virtual interactions provided by the game.
