A teoria da atividade e um framework relevante para o campo do Design, sendo suas representacoes graficas artefatos cognitivos que auxiliam no entendimento, uso e comunicacao desta teoria. Porem, existe uma falta de consistencia em torno dos elementos graficos e rotulos utilizados nestas representacoes. Com base nisso, o objetivo deste trabalho foi identificar, analisar e avaliar essas diferencas, propondo ao final uma representacao que pretende ser mais adequada para a teoria. Para isso, parte de uma revisao bibliografica com base no trabalho de Engestrom (2001) e suas tres geracoes de modelos visuais, aliada a analise grafica das representacoes coletadas em cem artigos de periodicos internacionais. Abstract Activity theory is a relevant framework for the Design field, and their graphic representations are cognitive artifacts that aid the understanding, use and communication of this theory. However, there is a lack of consistency around the graphics and labels used in these representations. Based on this, the aim of this study was to identify, analyze and evaluate these differences and propose a representation that aims to be more suitable for the theory. For this, uses as method a literature review based on Engestrom (2001) and its three generations of visual models, combined with graphical analysis of representations collected in a hundred papers from international journals.
