Research And Design Of Ubiquitous Human-computer Interaction System Based On Printer Of Ontology

There are two parts in the ubiquitous human-computer interaction system. The one part is equipment perception based on natural language, people's gestures, voice and virtual reality. And the other part is the ubiquitous interaction. The study of multimedia perception is mature. And with the equipment operation interface becoming more diverse, some researchers pay more attention to the ubiquitous interaction for achieving the goal of generality.The ubiquitous interaction enables the device "disappeared" in the process of human-computer interaction, attracts people to pay attention to complete the task itself. The researchers proposed lots of techniques to achieve ubiquitous interaction, including multi-channel parallel, user psychological perception, context aware, and so on. But the implementations of these techniques are based on a perfect knowledge representation. So the introduces a new knowledge description method is necessary.The paper constructs the ubiquitous human-computer interaction system based on printer domain, aims to solve ubiquitous interaction part. Conveys the users'demands of their own perception to the equipment, the device can analyze the needs automatically and give solutions of requirements based on current equipment. There are three parts in this process. Firstly, to understand the users'requirements, that is to translate users'demands to the device.It includes two parts, the one is multi-channel perception technology, the other is requirement standardized processing. Secondly, processes the demands variation, gives solutions to standardized demands based on specific equipment, contains both of the function matching and the parameter matching. Thirdly, obstacles process, to solve the unexpected conditions during the system running. This paper introduces ontology as the knowledge base of the system, constructs object attribute ontology, device function ontology, task-method ontology and obstacle ontology, processes the data based on ontology, and applies ontology to guide the each part of the system, and defines the implicated system knowledge in the ontology to realize the knowledge sharing.The paper defined more than twenty kinds of printer information in the ontology, and verifies the consistency and extensibility it. A prototype named MyUI is implemented, Take the OKI and HP printer as example, carries on test of the system's ubiquitous human-computer interaction, confirms the feasibility of the ontology-based ubiquitous human-computer interaction, and makes a contribution to the ubiquitous human-computer interaction based on ontology.
