Pedro Branco defends master dissertation entitled "Digital signage - event-based application using Google Calendar API"

Pedro Miguel Pereira Tomé Branco has requested the defence of his dissertation, entitled "Digital signage – event-based application using Google Calendar API". The defence will be held in room A1 of the Departamento de Informática, on December 19, 2011, 04:00pm. The public is invited.

The examining committee is the following:

  • António Costa (UMinho) - president
  • Benjamim Fonseca (UTAD) - opponent
  • António Nestor Ribeiro (UMinho) - supervisor


The usage of digital signage displays in public and semi-public places is increasing, because they are a modern way of dynamically displaying information, advertisements and entertainment content. In this way, those exposed to digital signage have a quick and up to date access to information around them.

Display screens have been improving in quality. Also prices have been falling, making this technology more affordable in order to be applied in various areas (particularly in industry, commerce, education, health, etc.), replacing the paper-based traditional means of advertising and information.

A digital signage network allows the remote update of its contents, based on a central server that manages all the information presented on the network, while in traditional means the contents’ updating process is much more costly, time consuming and difficult to manage.

Because people glance briefly into the displays, their content and locus must be carefully studied, so that the environment becomes more attractive. Thus it is a way to promote the attention of the passersby. Some displays use more sophisticated technologies, allowing a context-based automatic adaptation of their content. So the information is targeted to the public, without the need for human control.

Ever more software solutions applied to digital signage have emerged due to its increasing success in a worldwide scale. Therefore the development of a digital signage web application that allows the set up of views with event information coming from Google Calendar (proposed by Ubisign company) will be the main theme of this dissertation.

Since event promotion generally requires high costs of design and production, they must be minimized in digital signage networks. To this end, some online tools for managing events, such as Google Calendar, allow calendar-based event scheduling and its specification. From a developer’s perspective, these tools avoid the need to implement other event management software, allowing one to develop other applications that communicate with these tools through appropriate and well documented APIs. To take advantage of this, the application that will be developed will need to use the Google Calendar API to provide information in a personalized way about events that are planned for a given place with an installed digital signage network. For this purpose, the application must be integrated in the service
