© 2018 IEEE. In this paper, we propose the smartphone operation support system for visually impaired. It is difficult for visually impaired people to grasp complicated screen configuration of smartphone. Visually impaired people have a problem that the people don't know the operation position of touch panel. Therefore, we created the touch screen application for visually impaired people to get the information easily. As a result, when comparing conventional application and proposed application in three environments 'screen display', 'screen non-display', and 'blindfold', we confirmed a drastic reduction in operation time of proposed method.

Study on headphone hearing loss prevention methods based on the melody structure of music on portable music player 査読有り国際誌

© 2018 IEEE. In this paper, we examine the volume control system in an application to prevent the onset of headphone hearing loss due to music listening using a portable music player. First, the possibility that lower the volume to a safe level without be noticed by the user (difference of perceived attenuating level) are evaluated. As a result, the notice happened when volume level was attenuated 11 ± 3 dB, and it not be affected by changing attenuation rate of volume level. Based on the above experiments, we examine the melody structure of music by attenuate the volume separately for melody structure (Intro part, Verse, Chorus, Interlude). As a result, it was found that the intro part was hard to notice the volume attenuation, and in the part of the chorus, it was easy to notice the volume attenuation. Next, we evaluated difference of the perceived attenuating level considering frequency characteristics. As a result for the low frequency, it was difficult to notice the volume attenuation, and the high frequency tends to notice the volume attenuation.
