    1. 1. Semiotics andTechnology
    2. 2. Peircean Semiotics• All signs are made up of three parts. • Abstraction (signified) • Reality • Law (Signifier)• Categories are frequently referred to as: • Firstness – Quality of Feeling • Secondness – Reaction, resistance, relation • Thirdness – Representation, mediation
    3. 3. Firstness: Thirdness:•icons – likeness •symbols – meanings by use•potential •laws•pure abstraction •habitual regulations•chaos – pure potential •patterns – govern other 2 categories Secondness: •indexes – point to things •existence •fact •conflict - opposition

    5. 5. A semiotic engineering approach touser interface design• The defining trait of our semiotic engineering approach is that software artifacts are meta- communication artifacts. They are one-shot messages sent from designers to users about the range of messages users can exchange with systems in order to achieve certain effects.• Effective HCI can only be achieved if both levels of communication are successful in their particular way. • Two-tiered communicative process involving designer- to- user communication and user-system interaction.Clarisse Sieckenius de Souza*, Simone Diniz Junqueira Barbosa, Raquel Oliveira Prates
    6. 6. So…• The role of a semiotic theory in this perspective is then to tell designers how they should • make the communicative choices, so that the interactive system is good, and • convey their choice to users so that this communication does not get in the way of interaction, but serves as a secure scaffold for productive user activity.
