The translation of web content into Libras (Lingua Brasileira de Sinais – Brazilian Sign Language), although adequate, cannot always be implemented, due to its high cost. Thus, the present study aims to identify and propose solutions for the potential communication breakdowns in the interaction of bilingual deaf users in corporate systems on the web. The analysis of the interaction took place a...

Although direct manipulation (DM) has been considered a potentially inappropriate interface style for learnware, convincing indication that the problem with DM lies rather on “what is manipulated” than on the “manipulation” itself has been obtained from empirical studies in the domain of Euclidean geometry. A semiotic examination of such findings suggests that there may be theoretically-based c...

Collaborative systems are growing more and more popular. However, evaluating this type of systems is still a difficult task. Many evaluation methods have been proposed to deal with this challenge, but most of them are not yet consolidated. Semiotic Engineering is an explanatory theory about HCI that proposes three different methods that can be applied to evaluate collaborative systems: MIS, MAC...

Semiotic Engineering is a semiotic theory of HCI that views humancomputer interaction as a contingent process of designer-to-user metacommunication. The theory currently has two evaluation methods, Communicability Evaluation and Semiotic Inspection. The aim of our research is to do a critical analysis of both methods in order to align them with each other, especially in ontological and epistemi...

This paper continues and extends previous work on the functions of selfreferential relational structures and processes in the articulation of semiotic ideas and hypotheses within biological theory. The inquiry explores the various ways in which self-referential loops are tacitly embedded in the interplay of some of the most basic and foundational notions of biosemiotics — notions ordinarily con...

This paper presents a formalisation of Peirce’s notion of ‘sign’ using a triadic relation with a functional dependency. The three sign components are then modelled as concepts in lattices which are connected via a semiotic mapping. We call the study of relationships relating to semiotic systems modelled in this manner a semiotic-conceptual analysis. It is argued that semiotic-conceptual analyse...

This article presents issues of communicability that can impact in the interaction of pre-linguistic bilingual deep deaf user in Web Organizational Information Systems. Thus, we seek to contribute to the development of more accessible systems to this user's profile, seeking its inclusion in the organizational environment. The analysis of interactions occurred in the Intranet of a science and te...

This paper intends to show how a semiotic model akin to a dyadic semiotic can contribute to knowledge representation issues. In particular we hope that it offers a viable alternative to triadic semiotic models usually evoked to build conceptual structures and knowledge representations.

This paper is an effort to discuss the concept of glocalization from a semiotic point of view. In order to carry out a semiotic analysis of globalization or glocalization, first globalization needs to be defined from a semiotic perspective. Therefore, first an explanation of globalization and glocalization in semiotic terms is provided. Some believe the ongoing process in the world cannot be be...
