A design of XML schema for information presentation system using augmented reality in new generation network management

In coming ubiquitous network society, a user who has no knowledge about network technology might have to manage his/her network including information appliances and sensor networks. Current network is, however, too difficult to manage because protocols to access ubiquitous network devices are not same and it is not easy to identify the cause of problems if a network failure occurs. Toward uniting protocols to access devices, we have designed Tambourine framework, which uses REST API to hide SNMP, NET-CONF and proprietary protocols for sensor networks and enables users to manage network devices using HTTP and XML under resource-oriented architecture. However, original Tambourine framework does not have an information presentation system which provides users with information without understanding of the network configuration. To bind real devices with the logical network configuration, we focus on augmented reality (AR) technology and designed an information presentation system using AR technology. AR technology enables users to monitor the device information which is displayed on that device. The object overlaid on AR is configured by an XML file, which describes main computer graphics (CG) object, size, font, color, degree of transparency, position and decoration. By using XML, developers can utilize XML processing technologies as represented by Web service technologies. In addition, XML has broad utilities, and our system provides users with an information presentation which meets their requirements. Furthermore, our system has user identification system and flexible information presentation system which is able to change CG objects according to the user´s request.
