The Semiotic Inspection Method - Overview, Analysis and Critique
The SemioticInspection MethodOverview, Analysis and CritiqueBy Omar Sosa Tzecinfo 502Human-Centered Research MethodsProf. John PaolilloPhD in InformaticsSpring 2013
analyzed work• de Souza, C., Leitão, C., Prates, R., da Silva, E. (2006) The Semiotic Inspection Method• de Souza, C., Leitão, C., Prates, R., Bim, S., da Silva, E. (2010) Can inspection methods generate valid new knowledge in HCI? The case of semiotic inspection• Peixoto, D., Prates, R., Resende, R. (2010) Semiotic Inspection Method in the Context of Educational Simulation Games
“In HCI the purpose of theory-based evaluationmethods is to assess the quality of the interfacesand the interaction in the light of a givenperspective on human-computer interaction.”de Souza, C., Leitão, C., Prates, R., da Silva, E. (2006)
“Unlike cognitive theories, which have tended tofollow a generalization path, semiotic engineeringviews human-computer interaction as a set ofunique and contingent instances ofmetacommunication from designer-to-user”de Souza, C., Leitão, C., Prates, R., da Silva, E. (2006)
“Evaluators using semiotic engineering methodsare the ‘producers’ (and reporters) of knowledgereferring to unique cases of HCI... Semioticengineering evaluation methods are qualitativeand interpretative.”de Souza, C., Leitão, C., Prates, R., da Silva, E. (2006)
the metacommunication template “Here is my [the designer’s] understanding of who you [users] are, what I’ve learned you want or need to do, in which preferred ways, and why. This is the system that I have therefore designed for you, and this is the way you can or should use it in order to fulfill a range of purposes that fall within this view.” de Souza, C., Leitão, C., Prates, R., da Silva, E. (2006)

case 1: analysis of feedback on simple css editorde Souza, C., Leitão,C., Prates, R., Bim,S., da Silva, E. (2010)Fuente: http://cloud.addictivetips.com/wp-content/uploads/2010/11/Simple-CSS.png
case 1: validation Exogenous Sources Google SCSS Groups Endogenous sim Sources Google Groups Help Forum sim triangulation
case 1: results• “It’s important to evoke the perceptible qualities that a configurableobject may acquire. These perceptible qualities are effectively signified by‘iconic’ signs, that is, signs that bring up the firstness of their referent.”•“The systematic association between parameter values and prototypeobject qualities [...] is a sign of secondness. [...] The user become skilled inanticipating the correct effects of using conventional symbols.”•“Once they dominate the symbolic representations that must be used toachieve their specific configuration goals, uses can be said to have learneda conventional configuration language, an unmistakable sign ofthirdness.”
case 2: analysis of feedback on simse game Peixoto, D., Prates,R., Resende, R.(2010)Fuente: http://cloud.addictivetips.com/wp-content/uploads/2010/11/Simple-CSS.png
case 2: validation SimSE Endogenous Sources sim triangulation
case 2: results•It was found that “the consistent use of icons, indices, and symbolsthat refer to the same feedback (redundancy) may improve the designermetacommunication.•This study reaffirms the “importance of the perceptible change of theiconic representation of the elements after changing of their attributes[in the game].”•It’s important to take in count the “correct visual effect of the indices[in the game].”•It’s also important to take in count “an explicit and consistent symbolicrepresentation of partial results and strategies used to calculate them[in the game] could improve the feedback [from the game].”
