In this paper, we propose an “ANC mute microphone” to attenuate noise caused by singing voice. To verify that an ordinary Filtered-X LMS Algorithm is effective in cancelling singing voice, we conducted simulations and experimented using the DSP kit DSK6713. The simulations show that the attenuation of a singing voice is modestly possible (up to 4 dB). According to the real-time experiment using the...
In this paper, a light-weight 3D object reconstruction system is proposed. It aims to fulfill the increasing demand for fast and reliable 3D reconstruction in a mobile environment. Thereby, people can directly use their own device (e.g. mobile phone or tablet) to reconstruct desired objects into 3D models. The system is implemented and tested on an embedded board, MIO-5250, that is equipped with the...
This paper proposes a pavement surface inspection system for wheel chair comfortability. Our proposed wheel chair, which can recognize its position and gather pavement surface point clouds, displays barriers on the pavement to wheel chair users after analyzing gathered data. We present our concept and discuss a visualization method on this system.
Web-based multi-screen digital signage system is designed to show a multimedia content via multiple signage screens which are connected by a network. In this demonstration, a novel method to control multi-screen digital signage is proposed. The proposed method uses standard web technologies to display same contents and seamless moving each devices screen.
In the emerging Internet of Things (IoT), consumer electronics are important components to create a smart environment. Embedded systems, which have internet connectivity in their limited resource, are often equipped with separate MCUs for device control and wireless communication. However, this approach is not cost-effective because of multiple MCUs. To solve this, we propose an IoT framework which...
In this study, we propose an algorithm that enables home appliances (air conditioners) and lighting fixtures to estimate real-time occupant metabolic rate based on their heart rate and provide better thermal conditions for occupants in smart home environment. Occupant metabolic rate refers to the heat production of occupants, and smart home appliances can use this data to control environment factors,...
A sports motion support system for golf swing has been described by using a perceptive sportswear and a wireless mobile device with Android application, in which a trainee is given real-time auditory feedback to be informed the performance of the swing. The wireless mobile device receives motion data from the perceptive sportswear designed in form of shirts and shoes in which hetero-core optical fibers...
