Immersive Edition of Multisensory 360 Videos

Authors
Coelho, H; Melo, M; Barbosa, L; Martins, J; Teixeira, MS; Bessa, M;

Publication
Trends and Advances in Information Systems and Technologies - Volume 2 [WorldCIST'18, Naples, Italy, March 27-29, 2018]

Abstract
The 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.

Digital signature solution for document management systems - The University of Trás-os-Montes and Alto Douro

Authors
Pereira, C; Barbosa, L; Martins, J; Borges, J;

Publication
Advances in Intelligent Systems and Computing

Abstract
The 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.

Context-aware HDR video distribution for mobile devices

Authors
Melo, M; Barbosa, L; Bessa, M; Debattista, K; Chalmers, A;

Publication
Multimedia Tools Appl.

Abstract
HDR video on mobile devices is in its infancy and there are no solutions yet that can achieve full HDR video reproduction due to computational power limitations. In this paper we present a novel and versatile solution that allows the delivery of HDR video on mobile devices by taking into account contextual information and retro-compatibility for devices that do not have the computational power to decode HDR video. The proposed solution also enables the remote transmission of HDR video to mobile devices in real-time. This context-aware HDR video distribution solution for mobile devices is evaluated and discussed by considering the impact of HDR videos over conventional low dynamic range videos on mobile devices as well as the challenge of playing HDR videos directly locally or remotely. © 2016 Springer Science+Business Media New York
