    Crowdsourcing Augmented Reality Environment (CARE) for aesthetic evaluation of products in conceptual stage
    (ELSEVIER SCIENCE BV, 2018-08-01) Arbeláez J.C.; Osorio-Gómez G.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
    Decision-making activities affect to a larger extent the quality, cost, time and success of a product. However, there are fewer alternatives when it comes to supporting in aesthetic evaluation during the product design stages. Therefore, is proposed a Crowdsourcing Augmented Reality Environment (CARE) that use the user's mobile devices for getting the feedback from the evaluation of products using a Semantic Differential (SD) that consider the user's context-light interaction in real time. Finally, two products were evaluated using CARE vs. the real products under different lighting and surrounding conditions. Obtaining a similar measure of products aesthetic perception between CARE and the real product, with slight variations. Additionally, an evaluation pattern among users was recognizable in the same context with slight variations using different lighting setup, that was similarly recreated with CARE. © 2018 Elsevier B.V.

    Probabilistic extension to the concurrent constraint factor oracle model for music improvisation
    (Asociacion Espanola de Inteligencia Artificial, 2016-01-01) Toro, M.; Toro, M.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    We can program a Real-Time (RT) music improvisation system in C++ without a formal semantic or we can model it with process calculi such as the Non-deterministic Timed Concurrent Constraint (ntcc) calculus. “A Concurrent Constraints Factor Oracle (FO) model for Music Improvisation” (Ccfomi) is an improvisation model specified on ntcc. Since Ccfomi improvises non-deterministically, there is no control on choices and therefore little control over the sequence variation during the improvisation. To avoid this, we extended Ccfomi using the Probabilistic Non-deterministic Timed Concurrent Constraint calculus. Our extension to Ccfomi does not change the time and space complexity of building the FO, thus making our extension compatible with RT. However, there was not a ntcc interpreter capable of RT to execute Ccfomi. We developed Ntccrt -a RT capable interpreter for ntcc- and we executed Ccfomi on Ntccrt. In the future, we plan to extend Ntccrt to execute our extension to Ccfomi. © IBERAMIA and the authors.
