Very nice, Guilherme. I love the way you put it: translating selves into users. Too bad your paper is not available, I would like to know more about the model and how it relates to Peircean semiotics. Now, from a more philosophical point of view, I wonder if we could think of this ongoing process, as you explained, in the same vein of the self-user. The psycologycal self is always evolving, too, I guess, but often repressing stuff from lived experience into the depths of the psyche, whereas the user seems to star of as an underdeveloped self for the designer who repreesses features because of certain predujicial choices or lack of lived experiences (in other cultures or ethnic landscapes, for instance). I am really interested in these information - matter - information translations of the digital subject, so your paper was very insiteful for me, thank you!
