This paper proposes a method for separating the voice of a signal person from the voices of multiple speakers' in a mixed recording. When the sounds of multiple speakers are present when a voice recognition system is operating, the quality of speech recognition decreases. The proposed method separates the sound of multiple speakers using signal processing techniques and a microphone array. The position...
Interest in sound interfaces is increasing because such interfaces do not need advanced knowledge about particular devices, nor do they require physical operation. However, such interfaces are difficult to use because the general living environment often contains background noise. In order to solve this problem, sound separation systems that use a microphone array sensor have been proposed. In previous...
Development of a robust and precise voice interface could accelerate the realization of a learning support system that utilizes voice. In our research, this objective is called Intelligent Interactive Design of learning support. In order to realize Intelligent Interactive Design, we propose a “voice separation and recognition system” that aims at clear voice separation for robust voice recognition...
In this study, we estimate gaze direction using the relationship between the face and eyes. The face and eyes are divided laterally and in lengthwise direction. We set up an object laterally and in lengthwise direction and measured the face angle using a Kinect sensor, which is range image sensor, when gazing at an object. The angle of the eyes is fixed at the angle of the object and grasp of the...
This paper presents a system to support learning within museum for children as a novel application of Kinect based human sensing system. The system measures the physical movement of the learner using a Kinect sensor, and provides a sense of immersion in the paleontological environment by adapting the surroundings according to these movements. As the first stage of this project, we have developed a...
In this paper, the relationship between visual attention and eye blinking is described. In our experiment, we observed blinking when a subject performed a task. We determined that the subject's visual attention functions during the task by electrodermal activity. Experimental results showed that blink rate decreased when the subject's visual attention was engaged. On the other hand, blink rate increased...
We developed a sound separation system that uses a microphone array to separate children's voices from background noise in general living environments. Our focus in the development of this system is on “a clear separation of the human voice” so that it will be easy for children to use. Evaluations conducted of sound separation performance in previous research have not always measured how easily listeners...
This paper presents a spherical microphone array design which can be used for capturing a sound selectivity and locally. Capturing a sound by microphone array is achieved by method of Delay and Sum Beam Forming (DSBF). In this method, microphone arrangement has a large effect on the directivity. Using beam forming simulation, the authors investigated on the optimal arrangement of concentrically spherical...
In recent years, microphone array signal processing has been actively studied in the field of engineering. In consideration of our hope that children's interest in this technology will contribute to the future development of science and technology, we have developed the KIKIWAKE system with a microphone array and conducted the Prince Shotoku Game to promote children's interest. Then, we confirmed...
The authors propose a novel application of human sensing technology to inclusive education. We focus on puppet show to aspire the inclusive education for both the normal hearing and the hearing impaired. Thus, we are developing Puppet Theater system to entertain both hearing impaired and normal hearing. This Puppet Theater system consists of two functions. First, the lines are displayed as letters...
In this study, we have improved the Universal Puppet Theater. Improvements have been made to branching scenes in the story. The exploratory evaluation experiment was a within-subject comparison of the existing version and improved version of the system. The subjects were 53 hearing-capable fourth-grade elementary school children. The results of analysis showed that the improved version of the system...
