- EEG analysis of the construction of empathy towards people with Schizophrenia, after exposure to virtual reality environmentsPublication . Marques, André; Gomes, Paulo Veloso; Sá, Catarina; Marques, António; Pereira, JavierSchizophrenia is considered a complex syndrome, with multifactorial neurodevelopmental alterations. Empathy is a complex fundamental component of human emotional experience, which influences one's emotions and behavior. On the Electroencephalogram, an activation of the dorsolateral prefrontal cortex is characterized by a decrease in alpha activity. The main objective of this work is to understand if the immersive tools of Virtual Reality influence the electrical activity of the brain and the heart. The two immersive tools were able to increase empathy, mainly by altering prefrontal brain activity as well as heart rate.
- Virtual reality cognitive-behavioral therapy biofeedback system for glossophobiaPublication . Correia, António; Gomes, Paulo Veloso; Donga, João; Marques, António; Pereira, JavierThe fear of public speaking is one of the most common social phobias causing anxiety problems in many people. In this context, this project focuses on developing a tool capable of helping mental health professionals using virtual reality as a controlled environment in expository therapies, in this case applied to Glossophobia. To enhance the creation of self-control mechanisms in these patients, the use of virtual reality is explored with the aid of Neuro and Biofeedback, allowing the visualization in real time of the physiological response to the stimuli of the virtual environment.
- Strategy for data cybersecurity in european health data ecosystemPublication . Curado, Henrique; Gomes, Paulo Veloso; Jacquinet, Marc; Marques, António; Pereira, JavierThis study aims to analyze the Strategy for Data Cybersecurity in the European Health Data Ecosystem, to be implemented in 2025.

- Mixed reality in surgery – a delphi studyPublication . Veloso, Rita; Magalhães, Renato; Lima, Ana; Gomes, Paulo Veloso; Marques, António; Pereira, JavierVirtual Reality, Augmented Reality and Mixed Reality all have useful applications in the field of medicine, but Mixed reality has great potential because it allows for interaction with both real and digital Objects. Based on a previous literature review, a preliminary Delphi study was performed to obtain the opinion of a panel of 22 experts from several hospitals on the use of Mixed Reality tools, such as the HoLoLens 2, in surgeries. After data collection, a consensus letter was signed. According to experts, the most useful areas are medical education and surgical planning.
- The impact and consequences of deepfakes in cyberspace on the social environmentPublication . Manuel, García; Sá, Vítor J.; Gomes, Paulo Veloso; Marques, António; Pereira, JavierWe live in an era daily inundated with information, and the economy of attention makes us far from the truth. The present study has its core to study the creation, use and sharing of videos originated by artificial intelligence that can make it appear that a person says or does something, although he has never said or done anything of the kind. This content is called deepfake. The problem is the way this content is propagated, which for the untrained eye it can be seen as authentic. Quantitative research was carried out, through an inquiry and a literature review.
