Effective use of various wireless network interfaces is expected. In this paper, we evaluate Quality of Service characteristics of mobile 4K video using a radio communication quality map. We collect radio communication quality (e.g. throughput) by smartphones and visualize the quality in a heat map. Using this map, we select two routes that are expected to bring the highest and the lowest communication quality. We then evaluate QoS characteristic of 4K video streaming using MPEG-DASH on these two routes. The result shows that a good route user can achieve 1.5 times higher communication quality than a bad route user.

Unconstrained monitoring of runner's body movements is important for grasping the running performances based on natural body motions. A perceptive sportswear, which means a wear itself having the perception to monitor human body motions without constraint, can be realized by using hetero-core fiber optics with advantages of thinness, light-weight, and flexibility. We have developed such sportswear with the embedded optical fiber which can monitor the body motion based on the light intensity changes. In this report, the perceptive sportswear with the mobile capability has first been tested in actual running field for monitoring the body forms and paces during running.

The purpose of this paper Is to develop a simplified localization method for indoor navigation with a few system complexity. It is possible to localization more certain precision by a few sensors, and yet that is effective for application to indoor navigation immediately. The distance and the angle from an acoustic marker with a pair of microphones was estimated by measuring the sound-level (SL) and SL difference, respectively. Through the experiment, it was concerned that proposed method would perform enough to localize the marker, if it was near to the microphones.

At movies theaters and with the new very large home television screens, multiple people simultaneously watch video images together. In this study, we further developed our system that measures two persons' gaze movements simultaneously as they watch video images, in order to evaluate the degree of agreement in their interest and their empathy while viewing the images. We measured the gaze movements among pairs of six adult subjects while they viewed three genres of TV programs, and we analyzed the subjects' head movements as well as gazing points.

In this paper, a content-based image retrieval technique applied to compression domain for the newest video coding standard, high efficiency video coding (HEVC), is developed. We propose to extract the features from intra frames, which are only partially decoded. The directions of intra mode are taken as a part of the feature when the corresponding sizes of prediction unit are divided into two groups. The second part of the feature is the histogram of the signal power of residuals. The experimental results show that the proposed method can reduce the resource consumption and achieve a good retrieval performance in Oxford 5K dataset.

We included the game in the Website to offer sightseeing information. The tourist play this game in Website, they can get more detailed sightseeing information. Specifically, when the tourist go to the tourist spot actually, the marker is scanned by the user's mobile device. Then the quiz about the tourist spot is shown to the user's mobile device. Further, the marker is put up by the spot in the tourist spot. The tourist goes around the tourist spot while answering the quiz. The user gets the score dependent on the degree of correct answer of the quiz.

This paper describes a measurement system for a wearable device of intra-body communication, in which the human body is used as a transmission medium. An instrument driven by AC power overestimates a voltage signal around the human body received by the wearable device, preventing precise measurements from being performed. We developed a new measurement system using an electro-optic technique to enable precise measurements. The wearable device is electrically isolated from the instrument. The measurement system has a bandwidth from 10 kHz to 20 MHz and a 40-dB signal-to-noise ratio at a wearable transmitter output voltage of 0.36 V.

In recent years, projector and the screen is being used by lecturers in the university. The large classrooms might prepare multiple projectors and screens to display the same image of the main screen. But it is high cost. This paper proposes a low-cost implementation of lecture distribution system for classroom. This system detects the laser pointer spot on the main screen and output the slide images with a pointer cursor along with the pointed spot in a mobile device's Web browser.

Normally, bedridden patients need nurses to help moving their body or changing lying positions. However, to patients, changing lying positions by others may cause two problems: One is the timing and frequency of movement may not be adequate and the other is the cozy position of the movement may not be perfect for patients. Therefore, in this study, we tried to build up a handy system which can help bedridden patients to control hospital beds in several lying positions that match their preferences closely by only moving their eyes. In the results, we have already built up an eye-controlled equipment which allowed user to control hospital beds by themselves. This equipment had advantages of light and handy. Besides, we also constructed a model of our homemade hospital bed with six specific bed boards. This new type may help users to change their lying positions in left right tilt. In the future, we expect that this handy system can help bedridden patients to appropriately control hospital beds in several lying positions that match their preferences closely by only moving their eyes.

Perceived directions of sound sources presented through bone-conduction (BC) headphones inclined toward the center, rather than air-conduction headphones. Such difference losses some merit of BC headphones as hearing aids. We previously proposed a design concept to compensate the discrepancy of perceived direction of arrival for BC headphones based on emphasis of interaural level difference (ILD). In this study, we have implemented the compensation method and evaluated its performance. As a result, the perceived direction through BC headphones was improved with the proposed ILD emphasis although little difference still remained.
