Exploração do ciclo-de-vida de aplicações interactivas (baseadas na web) para ecrãs públicos

Abstract

Public display systems are becoming increasingly complex. They are moving from passive closed systems to open interactive systems that are able to accommodate applications from several independent sources. This shift needs to be accompanied by more flexible and powerful application management. What currently occurs in most public displays is that the displayed content is based on a pre-defined timetable where each content is given a certain amount of time. This traditional approach still fulfill current public display needs because most present applications are not interactive and it's possible to know in advance the time they need to properly execute. However, this approach will become obsolete as the public displays move to the more complex envisioned scenario. The result of this study is a complete framework developed as a Chrome Extension supporting a runtime lifecycle model for interactive public display applications that addresses several shortcomings of current display systems and will support some requirements of the new generation of displays.
