    • A Prototype of EEG System for IoT 

      Laport López, Francisco; Dapena, Adriana; Castro-Castro, Paula-María; Vázquez Araújo, Francisco Javier; Iglesia, Daniel I. (World Scientific Publishing Co. Pte. Ltd., 2020-05-04)
      [Abstract] In this work, we develop open source hardware and software for eye state classification and integrate it with a protocol for the Internet of Things (IoT). We design and build the hardware using a reduced number ...

    • Adaptive model for biofeedback data flows management in the design of interactive immersive environments 

      Marques, António; Donga, João; Sá, Catarina; Correia, António; Pereira-Loureiro, Javier; Gomes, Paulo Veloso (MDPI, 2021-05-30)
      [Abstract] The interactivity of an immersive environment comes up from the relationship that is established between the user and the system. This relationship results in a set of data exchanges between human and technological ...

    • Analysis and Definition of Data Flows Generated by Bio Stimuli in the Design of Interactive Immersive Environments 

      Gomes, Paulo Veloso; Donga, João; Marques, António; Azevedo, João; Pereira-Loureiro, Javier (MDPI AG, 2020-08-20)
      [Abstract] This work focuses on interactivity as one of the essential factors for creating immersive environments, particularly interactivity that generates involuntary responses over which the user does not have conscious ...

    • Application of Adaptive Virtual Environments Through Biofeedback for the Treatment of Phobias 

      Donga, João; Gomes, Paulo Veloso; Marques, António; Pereira-Loureiro, Javier; Azevedo, João (MDPI AG, 2020-08-25)
      [Abstract] This study proposes solutions to help people with phobias through the use of virtual environments that allow a contact between the subjects and these phobias. Using neurofeedback, the systems, depending on the ...

    • Computer-assisted analysis of polysomnographic recordings improves interscorer associated agreement and scoring times 

      Álvarez-Estévez, Diego; Rijsman, Roselyne M. (Public Library of Science, 2022-09)
      [Abstract]: Study objectives To investigate inter-scorer agreement and scoring time differences associated with visual and computer-assisted analysis of polysomnographic (PSG) recordings. Methods A group of 12 expert scorers ...

    • Convolutional Neural Networks for Sleep Stage Scoring on a Two-Channel EEG Signal 

      Fernández-Blanco, Enrique; Rivero, Daniel; Pazos, A. (Springer Nature, 2019-06-26)
      [Abstract] Sleeping problems have become one of the major diseases all over the world. To tackle this issue, the basic tool used by specialists is the Polysomnogram, which is a collection of different signals recorded ...

    • Eye State Detection Using Frequency Features from 1 or 2-Channel EEG 

      Laport López, Francisco; Dapena, Adriana; Castro-Castro, Paula-María; Iglesia, Daniel I.; Vázquez Araújo, Francisco Javier (World Scientific Publishing, 2023)
      [Abstract]: Brain–computer interfaces (BCIs) establish a direct communication channel between the human brain and external devices. Among various methods, electroencephalography (EEG) stands out as the most popular choice ...

    • Eye State Identification Based on Discrete Wavelet Transforms 

      Laport López, Francisco; Castro-Castro, Paula-María; Dapena, Adriana; Vázquez Araújo, Francisco Javier; Fresnedo, Óscar (MDPI, 2021)
      [Abstract]: We present a prototype to identify eye states from electroencephalography signals captured from one or two channels. The hardware is based on the integration of low-cost components, while the signal processing ...

    • Hyperthermia-Induced Changes in EEG of Anesthetized Mice Subjected to Passive Heat Exposure 

      Labra, Carmen de; Pardo-Vázquez, José L.; Cudeiro, Javier; Rivadulla, Casto (Frontiers, 2021-09-09)
      [Abstract] Currently, the role of hypothermia in electroencephalography (EEG) is well-established. However, few studies have investigated the effect of hyperthermia on EEG, an important physiological parameter governing ...

    • Proposals and Comparisons from One-Sensor EEG and EOG Human-Machine Interfaces
