Geo-referenced data is usually acquired and then stored into an existing GIS. With the advent of Mobile Computing Devices (aka PDAs), the integration task can be avoided. We extended a PDA GIS visualization system (Mordomo) in order to allow the update of metadata. In this way the task of updating geo-referenced data can be done on-site. In order for the system to cope with different applicatio...

Mobile devices are significantly changing the human-computer interaction. In particular, the ubiquitous access to remote resources is one of the most interesting characteristics achievable by using mobile devices such as Personal Digital Assistants, cellular phones and tablets. This paper presents an architecture that allows users to search and visualize complex three dimensional models over Pe...

This paper discusses a variety of potential applications of intelligent assistants, from personal digital assistant (PDA) to team digital assistant (TDA). We identify two challenges that arise when developing intelligent assistants in crisis management and give an overview of the different technologies that could be used to address these challenges. In particular we will focus on ontologies and...
