1A2-G04 知能化空間における音高情報を用いたサウンドヒューマンインタフェース 1A2-G04 A Sound Based Human Interface Using Pitch Information in Intelligent Space
This paper describes a simple but robust human interface for smart environments which are spaces with many distributed and networked sensors and actuators. Smart environments have to recognize requests from users to provide the desired services and it is desirable that the user can request the services through natural interfaces. Therefore, a suitable human-smart environment interface is needed. In this paper, since a sound can be easily detected by using distributed microphones, we focus on a sound based human interface and utilize the pitch information of the sound. The frequency of sounds is considered as a trigger to call a service, i.e. a service is provided when the system detects a sound which has the corresponding frequency. The proposed approach is tested using various sound sources. The experimental results show that the developed system is able to recognize the sound robustly even in the presence of environmental noise.
