- Searching for Better 3D Baseline StimuliPublication . Silva, Manuel; Teixeira, Luis Miguel Lopes; Ferreira, Miguel; Oliveira-Silva, PatriciaThe use of accurate and appropriate physiological baseline procedures is essential in experimental paradigms in the field of neuroscience. However, the most challenging parts of designing a new study for experimental laboratory studies, especially when using psychophysiological measures, is the choice of the appropriate stimuli for the baseline or control task, in order to compute reactivity. This study aimed to select and validate the most suitable image category to be used as a baseline task, through self-report and physiological measures. The images were selected according to a previous baseline, but adding the 3D and virtual world component, which is the foundation of our experiment. An experiment comprising a number of visual stimuli (15 images) in a virtual world using a Virtual Reality system, in which we assessed valence and arousal through self-report measures after visualizing each stimulus. Our discussion will emphasize the challenges involved in choosing an appropriate type of stimuli for baseline tasks and suggest that caution is never wasted.
- Mobile applications in cultural heritage context: a surveyPublication . Silva, Manuel; Morais, Diogo; Mazeda, Miguel; Teixeira, LuísUnderstanding the existing characteristics of smartphones in cultural heritage will increase our understanding of what has been created so far, where the potential of mobile technology may be the best use in the future. Thus, in this study, the authors systematically review existing smartphone apps dedicated to cultural heritage, particularly in museums, streets, and cities, available in app stores, to identify trends and current features with potential impact in new apps development. A second goal is to find and study applications with features such as GPS, Live Notifications, Map, Photos, Video, Audio, Games, Augmented Reality, combined into a single app
- Developing an eXtended Reality platform for Immersive and Interactive Experiences for Cultural Heritage: Serralves Museum and Coa Archeologic ParkPublication . Silva, Manuel; Teixeira, Luis Miguel LopesDigital Heritage and Digital Humanities focus on distinct typologies of heritage: tangible and intangible Cultural Heritage (CH) objects and their preservation, education, and research versus the application of digital technologies to support research in the humanities. Both allow scholars to go beyond textual sources to integrate digital tools into the humanistic study. This project aims at supporting a new way of experiencing CH in the Serralves Museum and Coa Archeologic Park through more involving and culturally-qualified user experience. The main goal is to understand the potential of eXtended Reality within CH while also proposing the idea of developing a digital experience platform: an authoring tool based on an engine with core experiences functions that can be applied for developing multiple experiences for CH. This platform will contribute to new approaches, technologies, and tools for creating, processing, and delivering immersive and interactive content for engaging and meaningful experiences in these specific CH environments
