People pay attention to the relationship between drivers' state before driving and subsequent vehicle operation as drivers' state like insomnia and overwork may contribute to traffic accidents. In this study, we classified drivers' state based on their sleeping hours before each driving session, and then we tried to bring out the effects in vehicle operation data, 20 in total, due to drivers' sleeping hours. We used the hierarchical clustering by Nearest Neighbor method to classify sleeping hours before driving. We classified the length of sleeping hours in each subject under three states, and then we calculated the mean and the standard deviation of each vehicle operation feature per subject. As a result, there was a common trend for all subjects (in DBP, distance from a point where they stepped on the brake pedal to the point where the vehicle paused temporarily). Surprisingly, we found that lack of sleeping hours make the drivers step on the brake earlier than when they had adequate sleep (because the mean difference DBP between the two states was 5.6 meters).

A fingernail detection method with the allowance of the palm existence proposed. However, some fingernail areas cannot be extracted as nail candidate areas if they don't reflect enough light toward the camera. The authors found it a key to solve this problem to use the distribution of colors. The authors propose a new nail area extraction using this. In the experiments, the authors confirmed that our system using the proposed method could detect only fingernails at least 85% from -90 to -50 degrees and from 50 to 90 degrees and worked well from -50 to -30 degrees.

Learning character balance is important in calligraphy. Transcription is the practice method for learning characters, however it has some problems, for example, it is hard to judge intuitively whether character balance is correct, because the sheet of white paper and the sample image are separate. Therefore, the goal of our study is the construction of a support system for learning character balance in transcription, for beginners. The proposed system uses a tablet-type device. Learners practice transcription in Indian ink on a sheet of white paper laid on top of the tablet-type device which is displaying a sample character. Learners can see the contents displayed by the tablet-type device because a sheet of white paper is thin. Moreover, the tablet-type device can recognize the touch of a Japanese brush wrapped in conductive tape. The system offers a function that changes the sample characters based on the learner's skill level to withdraw from the system support. We have developed a prototype system, and evaluated its effectiveness through actual use of the system.

A novel cooperative spectrum sensing approach is introduced based on a approximate model of the power spectral density (PSD) map in space and frequency domain. This scheme uses a model coefficients estimator based the theory of Variational Bayesian Inference. It reveals the unknown positions of transmitting CRs and the spectrum holes in authorized frequency bands, by capitalizing on the forms of sparsity in Cognitive Radio Networks.

To show a computer screen on a large display, so far, wired cable connections like VGA, HDMI, and DisplayPort are mainly used. Recently, wireless display technology is becoming popular, especially on mobile devices like PCs, tablets, and smartphones. “Tap to Display” is a connection method triggered by an NFC tap operation. It enables users to show the desktop screen of his PC on the destination Miracast Sink device wirelessly without any extra user intervention - no wired cable connection and no extra Wi-Fi parameter settings. In this paper, the implementation of the “Tap to Display” experience is discussed. Also discussed is the NFC event handling library which dispatches private NFC tag events to several software components.

A novel aerial imaging system consisting of two roof mirror arrays is proposed. The proposed imaging system is based on heterogeneous imaging, which means that the system forms an aerial real image in a crosswise direction and a virtual image in a lengthwise direction. The aerial image formed by the proposed system is not distorted by Seidel aberrations because the imaging is based on retro reflection. We developed an experimental display system and confirmed an aerial image that can be seen naturally in spite of the aerial image was formed only in a crosswise direction.

Real estates and housing associations have to incorporate modern mobile and internet technologies in their service offerings to stay attractive for clients. While doing so, they must take into account the special needs of their target audience. The elderly is an increasing target group which refuses modern consumer electronics with overwhelming features. Therefore, easy-to-use interaction models based on natural language processing are essential. With IBM's Watson a new area for deep answering systems and semantic understanding of utterances arises. Our paper investigates the Watson approach, combines the used techniques with other artificial intelligence methods and develops an interactive concierge service.

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, including temperature and humidity for the optimal indoor climate. We also compared this heart rate-based method with the pre-existing location-based method in test bed to evaluate the effectiveness of both methods in estimating metabolic rate.

Dementia is one of the most serious problems in aging society. Aerobic exercise has good evidence for its prevention. Walking and cycling are popular and practical aerobic exercises. However, elderly people have problems in the walking and cycling, which come from lacks of physical / mental functionalities and unsuitable traffic environment. To provide safe and human-friendly environment for walking / cycling, we have developed virtual reality walking / cycling system. In this paper, a framework, which can easily and rapidly construct large-scale computer graphic data for the systems, was described. As an application, we reported about the trials for the psychophysics experiment on the traffic environment with the framework.
