Smart homes are driven by heterogeneity in nature and consist of diverse components that promote user comfort and security. In recent times, tremendous growth of Internet of Things (IoTs) applications is seen in smart homes. The huge diversity of various IoTs applications generally leads to interoperability requirements that need to be fulfilled. Current IoTs management is achieved using physical...
Planetariums are now projecting not only stars but also all-sky movies. The immersive movies can be new fun for auditory-impaired people if they are properly captioned. The author developed captioning technology for the planetarium movies.
We have been studying Cloud HNS, which is a new type of home network system using the cloud. In this paper, we consider value-added services that can be provided by introducing a smart TV as an appliance of Cloud HNS. First, we discuss requirements, role and benefits of a smart TV in the integration with Cloud HNS. Then, we propose concrete scenarios of value-added services achieved by the integration.
In recent years, the embedded devices are very popular, and the smart phone and Tablet PC are the most important consumer electronic products. When programmers design a program on PC, there are a lot of resources can be used to enhance the performance of the program. But the resources on embedded devices are limited. Thus, how to profile and optimize the programs on embedded system becomes an important...
Advances in TV technology have enabled viewers to actively interact with the TV through interactive applications instead of just passively watching TV. Typically, a conventional remote control is shared by many viewers and it is difficult to accurately capture the individual interaction data from each viewer. It is also difficult to identify the context in which the interactions occur, e.g., to manage...
In this paper, we propose hardware efficient implementation of lifting based 2-D DWT and Sobel based edge detector for detail diagnosis in Wireless capsule endoscopy (WCE) in real-time. Architecture is developed based on the properties of the endoscopic images and the CMOS sensors. Proposed edge detection scheme works on the compressed DWT coefficients and offers 83.1 % compression ratio (CR). VLSI...
Recently, people pay more attention to healthy living conditions. Such changing lifestyle leads to demand for wearable health monitoring, new medical technology, healthy food and clean air. Thus, indoor air monitoring and control will be an emerging industry with a huge market size. In this paper, we have developed an indoor air monitoring system with ability to observe volatile contaminants, especially...
We propose an immersive projection display with dynamic reflectance control using photochromism. The reflectance control is effective for inter-reflection compensation. Software-based inter-reflection compensation techniques, which are conventional techniques, suffer from the projector's limited dynamic range in reproducing the target appearance on immersive projection screens. To solve this problem,...
This paper analyzes the application of multihop relaying to improve the physical layer security of a wireless body area network (WBAN). Based on the channel characteristics of WBAN, the secrecy outage performance for single-hop and multihop transmission is studied. Results illustrate that multihop relaying performs much better than the single-hop due to the severe path loss caused by the human body.
In order to realize the high precision indoor positioning system, an embedded gateway is designed for data transmission and forwarding, and the server is developed on Windows platform for storing data, obtaining and showing location information. The indoor positioning system architecture is given, focusing on the design and implementation of gateway and server. ARM11 processor is used to design a...
In this paper, a household electric appliance remote controller operated without touching it is proposed. A prototype was prepared in order to evaluate the effectiveness of the proposed method.
Spreading Internet of Thing devices, we need an effective method for managing the devices. For that reason, we proposed Instance Manager that can provide intelligent services to end users with effective way. The proposed system has virtual objects as representing devices released by many companies for integrating the services provided by each device. In this paper, we will explain how to devise Instance...
This paper described a novel binary method for inhomogeneously lighted fingerprint optical coherence tomography (OCT) images. To reduce the light effect problem, a block size is calculated by the median value of the length values of white pixels between black pixels in the initial binary result and used to rescale the gray values of the input image. The rescaled gray image is used to calculate the...
In this paper, we evaluated the characteristics of the bone-conducted sound propagation in the human head through computer simulation using a reduced head model with finite element method. The model was made of three spheres, which represent the skin, skull and brain, and the brain was represented by the water for simplicity. The step response of the head was investigated to show that the sound propagation...
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.
We proposed a multi-agent and multi-player artificial school class game. This game has been designed to solve the bullying problem in school. Human players participate in the game and interact with other players, or agents, to make friends with those who have similar sense of values.
In this study, we developed a Multiple Skill Practice Management and results feedback System - sawing and planning. The system can be used for a beginner's vocational learning. Using this system, learners are able to meta-recognize their own skills without a teacher. This system consists of two parts; learners' motion sensing part by using smartphones, and store and visualization part of the data...
Robotic technology is gradually entering our everyday environments and it is expected that in future social robots will be used to provide various services to users of public spaces. However, robots nowadays still lack the abilities to sense and understand their surroundings, and even more importantly, they lack the knowledge on the persons' usual behavior in public spaces. This talk will discuss...
In this paper, we studied Stacked Denoising Autoencoder(SDA) model for Human pose-based action recognition. We used public dataset Chalearn 2013 which contains Italian body language actions from 27 persons. We studied two model of SDA for pose clustering: 1) Traditional SDA with epoch and Neural Network supervised classifier and 2) Marginalized SDA which faster and ELM supervised classifier. We used...
