Dynamic world model for context-aware environments
Baras, KarolinaTese de doutoramento Tecnologias e Sistemas de informação ; The main subject of this dissertation is a dynamic symbolic world model which is connected to sensor networks through data acquisition and processing modules. Being dynamic, it is capable of accompanying the state of the represented spaces in real time. This model can be distributed over several servers as all the objects in the model are uniquely des...
Groups and frequent visitors shaping the space dynamics
Baras, Karolina; Moreira, AdrianoOur research is about a dynamic symbolic space model that is fed with data from the environment by a set of processing modules that receive raw data from sensor networks. For the conducted experiments we have been using data from a WiFi network as it is a widely available infrastructure in our campus. Here we propose two processing modules which will provide more information about the spaces described in the mo...
Navigation based on symbolic space models
Baras, Karolina; Moreira, Adriano; Meneses, FilipeExisting navigation systems are very appropriate for car navigation, but lack support for convenient pedestrian navigation and cannot be used indoors due to GPS limitations. In addition, the creation and the maintenance of the required models are costly and time consuming, and are usually based on proprietary data structures. In this paper we describe a navigation system based on a human inspired symbolic space...
