ItemDigital signature solution for document management systems - The University of Trás-os-Montes and Alto Douro( 2018) Luis Barbosa ; Pereira,C ; José Luís Martins ; Borges,J ; 6279 ; 6516The University of Trás-os-Montes e Alto Douro (UTAD), in an effort to streamline processes and reduce bureaucracy, decided to develop and use an in-house document management system to handle processes. However, this practice created additional needs such as the actual digital signing of documents associated with the institution business and administrative processes. This paper explores a solution proposal to this problem, documenting what are its functionalities and how it works. An initial application of the developed solution is also described and analyzed in order to demonstrate the overall adequacy of the proposed artefact and its overall impact to the institution administrative operations. © Springer International Publishing AG, part of Springer Nature 2018.

ItemEvaluation of the impact of different levels of self-representation and body tracking on the sense of presence and embodiment in immersive VR( 2022) Guilherme Santos Gonçalves ; Miguel Correia Melo ; Luis Barbosa ; José Vasconcelos Raposo ; Maximino Bessa ; 5095 ; 5408 ; 6279 ; 6565 ; 6871The main goal of this paper is to investigate the effect of different types of self-representations through floating members (hands vs. hands feet), virtual full body (hands feet vs. full-body avatar), walking fidelity (static feet, simulated walking, real walking), and number of tracking points used (head hands, head hands feet, head hands feet hip) on the sense of presence and embodiment through questionnaires. The sample consisted of 98 participants divided into a total of six conditions in a between-subjects design. The HTC Vive headset, controllers, and trackers were used to perform the experiment. Users were tasked to find a series of hidden objects in a virtual environment and place them in a travel bag. We concluded that (1) the addition of feet to floating hands can impair the experienced realism (p = 0.039), (2) both floating members and full-body avatars can be used without affecting presence and embodiment (p > 0.05) as long as there is the same level of control over the self-representation, (3) simulated walking scores of presence and embodiment were similar when compared to static feet and real walking tracking data (p > 0.05), and (4) adding hip tracking overhead, hand and feet tracking (when using a full-body avatar) allows for a more realistic response to stimuli (p = 0.002) and a higher overall feeling of embodiment (p = 0.023).

ItemImmersive Edition of Multisensory 360 Videos( 2018) Luis Barbosa ; Maximino Bessa ; Teixeira,MS ; José Luís Martins ; Coelho,H ; Miguel Correia Melo ; 5408 ; 5095 ; 6516 ; 6279The current technologic proliferation has originated new paradigms concerning the production and consumption of multimedia content. This paper proposes a multisensory 360 video editor that allows producers to edit such contents with high levels of customization. This authoring tool allows the edition and visualization of 360 video with the novelty of allowing to complement the 360 video with multiple stimuli such as audio, haptics, and olfactory. In addition to this multisensory feature, the authoring tool allows customizing individually each of the stimuli to provide an optimal multisensory user experience. A usability evaluation has revealed the pertinence of the editor, where it was verified an effectiveness rate of 100%, only one help request out of 10 participants, and positive efficiency. Satisfaction-wise, results equally revealed high level of satisfaction as the average score was 8.3 out of 10. © Springer International Publishing AG, part of Springer Nature 2018.

ItemA multisensory virtual experience model for thematic tourism: A Port wine tourism application proposal( 2017) José Luís Martins ; Ramiro Gonçalves ; Frederico Branco ; Luis Barbosa ; Miguel Correia Melo ; Maximino Bessa ; 5754 ; 6516 ; 6279 ; 5095 ; 5408 ; 6499Technological evolution has led to a significant transformation in tourism organizations, particularly in those who focus their activities on particular themes or segments, such as wine tourism. This can be transposed to Portuguese wine tourism organizations because the majority lack the necessary information and communication technologies (and inherent technologies) to become globally competitive. As highlighted in the literature, for a tourism experience to become memorable it must be emotional and immersive in such a way that the tourist becomes fully involved with the existing surroundings. This leads to the notion of using virtual reality experiences as triggers for the development of wine tourism. Considering the relevance of Portugal's Douro Valley to the country's wine tourism segment, a theoretical model that supports the implementation of multisensory (hence more immersive) virtual wine tourism experiences is developed. While considering the international success of Port wine tourism, this paper also presents a conceptualization of a multisensory virtual Port wine experience that includes a conceptual perspective and a technological solution proposal. © 2017 Elsevier Ltd.
