Contribuições da semiotica ao redesign de interfaces para ferramentas de comunicação eletronica

Flavia Rossler

Interaction among people is a necessity which grows everyday. The use of computers in mediating that communication is already a reality, and is spread out in a diversity of fields. Thus, the interfaces for human-computer interacion (HCI) through electronic communication tools need to enable the machine to be have as a medium which does not interfere in the communication by itself. Although the HCI literature presents several theories for interface design, there is a lack of formalizations for those theories. By considering the computer as a mediator in communication motivates the use of a Semiotic approach for the analysis and (re)design of interfaces for computational tools. In this work we propose approaching the analysis and (re)design, based on the combination of elements ITom two computational semiotic proposals: Andersen (1997) and Familant e Detweiler (1993). Our approach combines two perspectives: first, the focus is on the analysis of interface elements, using a typology for computer-based signs. Then, the analysis refers to the interpretability ofthe interface signs, considering the relation that each sign establishes whit its referent in the world. In order to apply the proposed approach, two case studies were conducted. The first one refers to a comparative analysis of the interfaces of two e-mail commercial tools. The second one is related to the analysis and redesign of the electronic forum through web, being used in an educational project named Caleidoscópio. Results obtained ITomanalysis the forum tool after redesign lead us to conclude that the proposed approach seems to be very effective as an instrument for analysis and (re)desing of interfaces
