Advertisement in Digital Signage environments demands the enrichment of the classic approach of recommendation focused on individuals by means of the delivery of ads for a group of people observing a public screen. Even though the accuracy that can be achieved in the recommendations is important, the degree of novelty perceived by the users is even more important. This balance can be obtained not only through the improvement of the recommendation algorithms, but also through an adequate multiscreen cooperation scheme. Therefore, this paper proposes an approach for the construction of a recommendations system for Digital Signage environments based on a Smart TV-Smartphone cooperation scheme. [ABSTRACT FROM AUTHOR]

We propose to use application "Screen Video Capture" (SVC) to observe and assess information literacy skills (information literacy). The proposed application is able to record all activity video displayed on a computer screen. This observation allows "non-invasive" as the search process, the selection and use of information. We present a pilot experiment in which we used the open source software CamStudio and focuses on research use of this application. [ABSTRACT FROM AUTHOR]

This paper presents an image synthesis algorithm for rendering views of a real scene taken with a virtual camera which is located between two real cameras. Specifically, this paper presents how, under certain conditions, a pair of views is enough to obtain a full set of possible views by following the line that joins their optical centers (baseline) without reconstructing explicit 3D models. Test results show the viability of the proposed algorithm for simple scenes (an object with a simple geometry, which is opaque, and does not present any occlusions). [ABSTRACT FROM AUTHOR]
