  • The use of portable EEG devices in development of immersive virtual reality environments for converting emotional states into specific commands  
    Publication . Sá, Catarina; Gomes, Paulo Sérgio Machado Veloso; Marques, António da Silva; Correia, António
    The application of electroencephalography electrodes in Virtual Reality (VR) glasses allows users to relate cognitive, emotional, and social functions with the exposure to certain stimuli. The development of non-invasive portable devices, coupled with VR, allows for the collection of electroencephalographic data. One of the devices that embraced this new trend is Looxid LinkTM, a system that adds electroencephalography to HTC VIVETM, VIVE ProTM, VIVE Pro EyeTM, or Oculus Rift STM glasses to create interactive environments using brain signals. This work analyzes the possibility of using the Looxid LinkTM device to perceive, evaluate and monitor the emotions of users exposed to VR.

  • Application of adaptive virtual environments through biofeedback for the treatment of phobias
    Publication . Donga, João; Gomes, Paulo Sérgio Machado Veloso; Marques, António da Silva; Pereira, Javier; Azevedo, João
    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 emotional state of the user, adapt the scenarios allowing more or less intensity. The phobias these systems treat are social phobia, entomophobia and claustrophobia. The solutions have been developed using Unity, Muse 2 and Vive HTC.
