Assistive Technology and Applications: Independent living of severe motor disabled users
No full textSome chronic degenerative diseases lead to communication problems and individual confinement. The progressive and total loss of motor functions induces in these patients anatrhria, i.e., inability of using the normal Augmentative and Alternative Communication systems (AAC), and also the impossibility of interacting with their surrounding environment. In patients affected by ALS and MS, even if other communication forms are damaged or lost, the ability of controlling eye movements is typically maintained. The eye trackers are able to determine the direction of the user's gaze and to use it as an input channel. Communication instruments based on eye-tracking are for some patients a possible solution, both to have a useful communication with family members or at longer distance, using Internet, and for the possibility to control the home environment using a computer controlled by their eye movements. This book tackles, even if in partial and limited way, the communication and independence needs of severe motor disabled person
Automatic Domotic Device Interoperation
No full textCurrent domotic systems manufacturers develop their systems nearly in isolation, responding to different marketing policies and to different technological choices. While there are many available approaches to enable interoperation with domotic systems as a whole, few solutions tackle interoperation between single domotic devices belonging to different technology networks. This paper introduces an automatic device-to-device interoperation solution exploiting ontology- based semantic device modeling. By explicitly modeling interoperation through ontology concepts and relations, the devised solution allows to automatically generate devicelevel interoperation rules. These rules, executed by a suitable rule-execution layer integrated in an intelligent domotic gateway (DOG), allow interconnecting arbitrary devices in a general and scalable manner. A case study is shown, where the automatic-generation of interoperation rules is applied to two real-world demo cases, with either KNX or BTicino device
The DOG gateway: enabling ontology-based intelligent domotic environments
No full textThis paper moves a first step towards the creation of Intelligent Domotic Environments (IDE) in real-life home-living. A new Domotic OSGi Gateway (DOG) is presented, able to manage different domotic networks as a single, technology neutral, home automation system. The adoption of a standard framework such as OSGi, and of sophisticated modeling techniques stemming from the Semantic Web research community, allows DOG to go beyond simple automation and to support reasoning-based intelligence inside home environments. By exploiting automatic device generalization, syntactic and semantic command validation, and internetwork scenario definition, DOG provides the building blocks for supporting the evolution of current, isolated, home automation plants into IDEs, where heterogeneous devices and domotic systems are coordinated to behave as a single, intelligent, proactive system. The paper introduces the DOG architecture and the underlying ontology modeling. A case study is also illustrated, where DOG controls a laboratory reconstruction of a simple domotic environmen
