Item An Intelligent Auditory and Visual Stimulation System for Indoor Spaces: Human Biosignals in Response to Stimuli(Korea Information Processing Society, 2025) Alvarez Garcia, Gonzalo Alberto; Zúñiga Cañón, Claudia Liliana; Garcia Sanchez, Antonio Javier; Garcia Haro, Joan; Asorey Cacheda, RafaelIn the age of digitalization, merging artificial intelligence (AI) and Internet of Things (IoT) has ushered in groundbreaking systems capable of impacting human behavior. This paper focuses on a system that integrates AIoT technology and explores its impact on human emotions and behavior to enhance human experiences in indoor spaces. The study developed a system that orchestrates a series of auditory and visual cues and monitors brain and cardiac responses to identify the effectiveness of audio–visual stimuli. AI algorithms enable us to comprehend and recommend actions concerning the stimuli within the civil infrastructure, thereby influencing individual and group behavior. The proposed system produces auditory stimuli, such as music or ambient sounds, along with visual stimuli, such as lighting and information systems. The system collected electroencephalogram (EEG) and electrocardiogram (ECG) signals to validate the capacity of these stimuli. This technological integration empowered the system to adjust to the needs of individuals and groups, thus enhancing the indoor experience. The study focused on identifying EEG responses in the late positive potential (LPP) and their correlation with ECG responses, particularly within LPP as an EEG component, as it relates to decision-making and emotional perception. By determining the LPP, the system can tailor auditory and visual stimulation to enhance user experience. This system has applications for enhancing learning, public space comfort, and mental well-being. Through adjusting auditory and visual stimulation based on biometric signals, the system can foster a more comfortable environment for concentration, productivity, or relaxation. Despite its potential, the system presents challenges such as individual variability and the need for clinical validation. Furthermore, ethical and privacy considerations must be addressed to prevent the use of invasive technologies. In conclusion, the proposed system is a significant advancement in the intersection of AIoT technology and its influence on biological processes. While challenges remain, the system’s capacity to enrich the human experience in indoor settings is promising.Item Aplicación móvil para promover el deporte en los gimnasios públicos y senderos de Cali, (GymGo!

Data mining offers very powerful tools that can be used to analyze data in urban environments. Our research uses the UrbanContext roles model to identify the states of the individuals within urban environments. Then, it applies supervised classification data mining techniques to the results obtained, and uses decision trees in order to facilitate the analysis of the individuals’ behavior. Finally, we present the prediction results obtained from a study made about the roles that individuals adopt depending on their context. From these data we successfully predict the different types of services we can offer in an urban environment.Item Deployment of Air Quality Monitoring Sensors over a Delay Tolerant Mobile Ad-Hoc Network in Public Transportation Systems(IEEE Computer Society, 2018-09-27) Asorey Cacheda, R.; Garcia Sanchez, A. J.; Zúñiga Cañón, Claudia Liliana; Marco Jornet, P.; Moreno Riquelme, P. A.; Garcia Haro, J.Poor air quality in urban environments is one of the major problems of modern cities. This paper presents a crowd-sensing approach that leverages the mobility of public transportation to monitor air quality in different inner-city areas over the course of a day. To meet this objective, we present a system architecture for the compilation of environmental data using low-cost mobile sensor devices equipped in public transport vehicles. Thus, the network topology has been designed to be robust and reliable, tackling connectivity problems through the use of delay-tolerant networks and Bluetooth ad-hoc gateways, and to be flexible, dealing with changing topologies through the use of mobile ad-hoc networks. The tests carried out in the public transportation of Cartagena (Spain) show the feasibility of the proposed architecture for this vehicle to infrastructure service and the effectiveness of deploying a mobile measurement system instead of fixed stations, which is the usual solution for many smart cities.Item Lightweight Blockchain for Data Integrity and Traceability in IoT Networks(Institute of Electrical and Electronics Engineers Inc., 2026-05-07) García, Laura; Cancimance, Carlos; Asorey Cacheda, Rafael; Zúñiga Cañón, Claudia Liliana; Garcia Sanchez, Antonio Javier; Garcia Haro, JoanData integrity and traceability are important challenges to provide security in the Internet of Things (IoT) networks, which are often vulnerable to data manipulation attacks due to their use of low-resource devices and wireless communication technologies. In this regard, blockchain is a promising solution to enhance IoT security, but the implementation of a conventional blockchain requires high computational and network connectivity resources that are not compatible with IoT networks. In this paper, we propose a lightweight blockchain for data integrity and traceability in IoT networks that adapts the Distributed Ledger Technology (DLT) feature of blockchain to the LoRaWAN wireless communication protocol. Our proposal offers data integrity without the need for complex consensus algorithms or cryptographic operations. We also have designed and implemented a logical LoRaWAN P2P topology that enables communication between the IoT nodes which comprise LoRaWAN’s characteristic star topology. Finally, we evaluate our proposal and demonstrate its feasibility and performance in terms of data traceability, and network overhead.Item Modeling the Urban Context through the Theory of Roles(Springer Verlag, 2013-12-14) Zúñiga Cañón, Claudia Liliana; Burguillo Rial, Juan CarlosUrban environments are intelligent spaces where a wide set of heterogeneous variables that directly influence the behavior of the individual converge. In this paper we present UrbanContext, a new model for urban platforms that follows an individual centered approach and validates the use of the Theory of Roles to understand the behavior of the individual within a social environment. The roles defined in UrbanContext allow the interpretation of the states of the individual, facilitating his interaction with the environment and offering services without damaging his privacy. We describe the UrbanContext model and the fundamental principles that have been identified in this design; likewise we present a first validation scenario for UrbanContext.Item Optimizing Ambiance: Intelligent RGB Lighting Control in Structures Using Fuzzy Logic(MDPI, 2024) Alvarez Garcia, Gonzalo Alberto; Zúñiga Cañón, Claudia Liliana; Garcia Sanchez, Antonio Javier; Garcia Haro, Joan; Asorey Cacheda, RafaelManaging red–green–blue (RGB) lighting conditions within structures may evoke emotions and positively influence behavior. Intelligent RGB lighting systems based on environmental data measurements can substantially enhance the perception of comfort. This study presents a challenge that requires a holistic and integrated approach to implement an automatic RGB artificial lighting control system that can be utilized in various structures and indoor environments. Initially, the challenge spans the identification of environmental variables directly impacting comfort up to the careful selection of suitable sensors. The result is the development of a sophisticated and autonomous system that can adjust RGB lighting in real time, creating environments that are both comfortable and energy-efficient. This automated system fosters the creation of appropriate atmospheres across different contexts. The identification and monitoring of environmental variables are achieved through a neuro-fuzzy control mechanism, where fuzzy rules and membership functions are defined based on late positive potential timings and the influence of artificial lighting on human emotions. The outcomes from this study are an interconnected system capable of performing both online and offline operations to enable the monitoring of environmental variables and the efficient management of artificial lighting based on these metrics. A pilot study, with reference to an EEG wave registry system, yielded significant results. These tests had a statistically relevant result with an average frequency of approximately 9.8 Hz, indicative of a state of comfort among people. Despite a 10% deviation margin, 87% of measurements during the test remained consistent. This research study contributes to human behavior by fostering a relaxing environment and enabling a reduction in energy consumption through the use of efficient lighting. Moreover, the environment intention enables the creation of stimuli in three emotional states: activation, relaxation, and neutral, allowing behavioral adaptation to an intention to occur automatically in fluctuating environmental conditions.Item Sistema de instrumentación y control de estimulación auditivo y visual con tecnología AIoT para regular el comportamiento(Universidad Santiago de Cali, 2024-09-30) Álvarez García, Gonzalo Alberto; Asorey Cacheda, Rafael; Zúñiga Cañón, Claudia LilianaThe instrumentation and control systems have allowed the analysis of various systems that touch all aspects of science, developing an evolutionary connection with the needs of human beings and their context, the revolution in the field of biology, industry are just some examples of these scopes. In addition, technologies based on IoT (Internet of Things) systems have interconnected the different devices of our lives, from the simplest thing like turning on or off a light bulb, to being able to control the temperature and humidity of our living spaces. Nowadays, the new reality has posed a new restart to social situations, environments, meeting spaces have suffered due to the situation of the COVID - 19 pandemic, these spaces have not had significant transformations, although our personal spaces, some of them mediated by technology, have been transformed, the conditions in spaces of social interaction have not had an adequate evolution to the technological elements they have. This difference between personal and social spaces has generated a need in which environments and environments must become agents with the capacity to interact with people and to allow both participants and administrators of the spaces a possibility to regulate people’s attitudes and evoke activating or relaxing behaviors. The objective of the work proposed here is to design and build an instrumentation and control system recording the environmental conditions of the environment and generate an auditory and visual stimulus, as a regulatory agent of the environment, with elements of the IoT with robust and accessible technology for the integration of systems for monitoring and control online and also its autonomous operation.
