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.

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.

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 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.

In this paper, we compared the Linear Discriminant Analysis (LDA) with Random Forest (RF) for musical instrument identification from clips with a mixture of instruments. As the first step, monotone samples from the Musical Instrument Samples (Univ. Iowa) and RWC Music Database were used to identify the individual instruments. For the Iowa monotones, an overall instrument recognition rate of 24.8% and 82.1% was obtained using LDA and RF, respectively. However, the rate degrades to 54.9% on the RWC monotones even with RF, most likely due to insufficient number of features to cover the increase in variability of this large database.

We propose a voice picking system that uses localized guide speech oriented towards the target object, and Head Tracking (HT), which maintains the localized speech position according to the user's head movement. We verified the usability improvements achieved by the proposed system. The task completion time was reduced by about 1.8 seconds (11.2%) compared to conventional diotic conditions. The post test questionnaire showed that the HT condition is preferred over conventional diotic systems by 1.92 on a 7-point scale. Thus, with the introduction of sound localization in voice picking systems, both the user satisfaction and task efficiency can be improved.

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.

In a free market economy, the preservation of cultural heritage sides inevitably needs visitors, i.e. customers. Germany has more than 2,000 castles from the medieval times; when palaces are considered as well, the figure is above 25,000. The competition is tough. For castles from the middle ages, customer relationship management (CRM) means to attract them, to entertain them on-site, and to motivate them to come back. Contemporary CRM of cultural heritage sites may deploy digital media technologies including augmented reality and game play. There is developed some systematic approach to CRM which is implemented for the castle Scharfenstein, Eichsfeld, Germany. The implementation is available by any customer free of charge.

Artificial three-dimensional (3D) video technology has generated significant interest in recent years. However, there are concerns about side effects such as eye strain that may result from viewing 3D video images. This visual fatigue is assumed to be related to a mismatch between convergence distance and focal length that occurs while viewing 3D content. In this study, we investigated the relationship between this mismatch and visual fatigue. Two subject groups completed an easy task while viewing a 3D image containing a convergence distance and focal length mismatch, and while viewing an image without such a mismatch. After the task, visual fatigue was evaluated using a flicker test and a simulation sickness questionnaire (SSQ). Experimental results demonstrated that viewing a 3D video image with the mismatch resulted in more visual fatigue than doing so without the mismatch.

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.
