    An Interface Design Method Based on Situation Awareness and Immersive Analytics for Augmented and Mixed Reality Decision Support Systems in Construction
    (2025) Pillajo de la Cruz, Ernesto Andrés; Mourgues Alvarez, Claudio Enrique; Neyem, Hugo Andres; González, Vicente A.
    Research on augmented reality (AR) and mixed reality (MR) demonstrated their potential to support decision-making in construction. However, most efforts emphasized technological advancements, often overlooking how to present and interact with information to effectively support decision-making in AR/MR environments. This study proposes an interface design method that integrates situation awareness (SA) and immersive analytics (IA), two complementary frameworks that address user information needs and immersive interaction design. The method guides the design of AR/MR interfaces by aligning information content, presentation, and interaction with SA requirements and IA design principles. To evaluate its effectiveness, the method was applied to develop AR and MR interface prototypes for a simulated decision-making task involving field managers during indoor construction activities of high-rise construction projects. Results show high levels of SA achieved by participants, with no statistically significant differences between AR and MR interfaces, demonstrating the method’s effectiveness to support SA in both environments. The proposed method provides a structured approach for designing immersive interfaces that enable better perception, comprehension, and projection in dynamic construction scenarios. Moreover, it provides designers with practical guidance for interface development and allows practitioners to assess existing AR/MR solutions based on their capacity to enhance SA through IA.

    MobileMap: A collaborative application to support emergency situations in urban areas
    (IEEE, 2009) Monares, Alvaro; Ochoa, Sergio; Pino, Jose; Herskovic, Valeria; Neyem, Hugo Andres
    One of the problems affecting fire departments in Latin America is the lack of a strong infrastructure to overcome their communication problems. Because these organizations are mainly volunteer and receive minimal support from government agencies, most existing solutions are not applicable for them. This article presents a low-cost mobile groupware application, which may be used in emergency situations to overcome the firefighters' communication problems. The tool, named MobileMap, allows exchanging textual and graphical information using mobile devices. Therefore, this solution complements the frequently over-used radio communication systems. This tool was evaluated in a simulated and a real scenario; the obtained results are highly encouraging.

    Towards Native Code Offloading Platforms for Image Processing in Mobile Applications: A Case Study
    (IEEE, 2017) Valenzuela Gallegos, Guillermo Esteban; Neyem, Hugo Andres; Benedetto Causa, José Ignacio; Navon Cohen, Jaime; Sanabria Quispe, Pablo; Karmy, Juan A.; Balbontin, Felipe
    In this paper, we present a real-life case study to show the advantages of a new code offloading solution focused on improving both performance and energy consumption for image processing mobile applications. From our experiments, we found that offloading an image processing task would allow up to 5.7x speedup and 85% of reduction in energy consumption for low-end devices, and 1.7x speedup and 64.3% of reduction in energy consumption for high-end devices.
