—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. In this paper, we propose a runtime lifecycle
model for interactive public display applications that addresses
several shortcomings of current display systems. Our model
allows applications to load their resources before they are
displayed, enables the system to quickly pause and resume
applications, provides strategies for applications to terminate
gracefully by requesting additional time to finish the
presentation of content, allows applications to save their state
before being destroyed and gives applications the opportunity
to request and relinquish display timeinfo:eu-repo/semantics/publishedVersio
