Ítem 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.Ítem Haptic Augmented Reality (HapticAR) for assembly guidance(Springer-Verlag France, 2019-01-01) Arbeláez J.C.; Viganò R.; Osorio-Gómez G.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)The use of Augmented Reality (AR) to support assembly tasks has been an area of interest from its origins in the 90s. Since then, the benefits that this technology could bring to assembly-related tasks have been shown. And, although several advances have been done in different areas such as software, hardware, and human interaction, there are still some problems that have not allowed AR to expand and reach its full potential. Thereby, authors propose a real-time vibrotactile guidance method based on the Gestalt continuity principle and developed a Haptic Augmented Reality application with a low-cost configuration to evaluate the support of the proposed method in assembly tasks. Thus, it potentially overcomes the existing visual issues of AR allowing the user to focus on the task and avoid over-reliance into the technology. The proposed system recognizes the different parts and sub-assemblies, generates the instructions to perform the assembly based on the target position and rotation of each part and verifies the assembly. Additionally, a test was conducted to guide the user in positioning a part, obtaining a high accuracy of rotation and location placement. Also, different functions of the application were tested and the results are suitable for supporting the user guidance. © 2019, Springer-Verlag France SAS, part of Springer Nature.
