This paper documents the services and changes that library staff at a group of 15 Canadian university research libraries highlighted on their main pandemic pages and social media accounts during the early days of the coronavirus (COVID-19) pandemic. Findings suggest that libraries in the samples adopted the following services and changes: closing the physical libraries; suspending all physical collection services and in-person events; continuing to provide virtual reference services; promoting access and usage of electronic collections; suspending late fees and renewing checked-out items with a new due date; and advising users to wait before returning borrowed items. Notably, all libraries in this study are operating as full full-scale as digital libraries. This study will provide lessons learned to other libraries around the world to help in reviewing their own operational policies for coping with the current COVID-19 pandemic and for future global public health crises.

This work describes the evolution of an approach based on augmented reality for authoring multimedia presentations. The BumbAR approach is based on the NCM model and explores the use of augmented reality and real-world objects (markers) as an innovative user interface for describing the behavior and relationships between the media objects that are part of a multimedia presentation. It was evaluated through a qualitative study based on the TAM model. The qualitative study aimed at evaluating users’ attitude towards using BumbAR. The results showed that the participants found that the proposed approach is both useful and easy-to-use, but comments made by them showed the need of including new functionalities in the BumbAR tool, which are described in this paper.

In this article we describe a prototyping environment, which allows an author to set up and test a complex hypermedia presentation. It contains a visual editor, based on a graph notation, in which the nodes are media objects and the edges are the synchronization relations between them; an execution simulator, which helps the author to test the presentation dynamics by manually triggering media related events; and a player, which allows the author to preview the presentation and to visually relate the execution evolution with the interpretation of the synchronization schema.

Data-centered approaches to multimedia presentation design and implementation can be developed by extending methodologies and technologies common in text-based applications. A multimedia report is a multimedia presentation built on a set of data returned by one or more queries to multimedia repositories, integrated according to a template with appropriate spatial layout and temporal synchronization, and coherently delivered to a user for browsing. We discuss the problem of defining templates for such multimedia reports with a focus on media coordination and synchronization. Multimedia presentations can be automatically generated according to the template by instantiating it on actual data instances. An XML language describes the spatial layout and the temporal constraints of the media objects. An authoring system and a player have been implemented.

In the modern educational space regarding the realities of the information society special importance is attached to issues related to the provision of a high level of informatization of education, which implies teachers’ mastering the necessary competencies and the ability to introduce e-learning resources into educational and training practice. Adobe Flash as one of the platforms for creating web applications and multimedia presentations enjoys greatest popularity with users including teachers. However, in connection with the announcement of discontinuing Adobe Flash support in 2020, the issue of choosing an analog to create web applications and presentations for use in teaching purposes is becoming particularly relevant. The article provides a comprehensive analysis of developing electronic educational resources by teachers using Adobe Flash and HTML5 for teaching math in primary school.
