In this paper, we introduce our project to develop a creating rhythm making system of musical instruments. In a museum where various kinds of musical instruments are displayed, It provides interactive displays by playing these musical instruments. It is efficient to come in touch with a background of them, but it is not easy to play at site rhythmically. The purpose of this study is developing the...
This paper describes experimental evaluations of encoding parameters that are appropriate for MPEG-4 Audio Lossless Coding (ALS) to compress high-resolution audio. MPEG-4 ALS Simple Profile defines the values of encoding parameters, such as the maximum sampling frequency and quantization bit depth, for making it easier to implement in the receiving applications. However, ALS Simple Profile does not...
We often use shortest route to reach safety place when disaster occurs, that is because it takes shorter time than others in many cases. However, it sometimes cause congestion and make evacuation time longer. In this paper we propose a method of selecting appropriate route for each evacuee according to variation of person number. We explain algorithms to select appropriate route for each evacuee and...
A content delivery network (CDN) is composed of several edge servers which are distributed in different regions and provide web objects locally. If a web client sends one request to an edge server that has no available cache, i.e., cache miss, this edge server must download web objects from other edge servers or the origin server and then store into the cache. In this paper, we study and implement...
Touch sensors are used as standard human to machine interfaces in many applications. However, current technologies that allow everyday objects to be used as touch sensitive surfaces are either expensive in terms of processing or hardware. In this paper, we propose the use of AC hum to implement a granite touch bar using three electrodes and demonstrate the localization of touch on the granite bar.
The gaze tracker has been considered as an important human machine interface for consumer electronics. High accuracy/precision results are reported for some gaze trackers, but the experiments are conventionally evaluated by fixing the head position with a head support. Compared with infra-ray (IR) gaze tracker, the head movement problem becomes more complicated for a visible light gaze tracker (VLGT),...
We developed Body-Braille as an information transmission support tool for the deaf-blind using vibrations. With two-point Body-Braille, a Braille pattern is divided into three blocks and transmitted via vibrations using two vibration motors. In each block, four types of information, “left,” “right,” “both,” and “no exist,” are transmitted via two vibration motors. For ease of wearing, we wish to express...
Collaboration between humans and agents is an attractive solution for some severe works such as disaster response. Although many organizations are introducing chat-based interfaces for the conversation with the systems, it assumes a fixed relationship between the customers and the agents. In this study, we propose a support mechanism for the collaboration between humans and agents in the scenario...
People can easily perceive object with incompletion boundary or combination of discontinuous edges. However, common approaches are difficult to segment an entire object without referring to completion contour. This paper introduces a scheme to reify an object based on law of closure in Gestalt psychology. The proposed scheme acquires initial boundaries and edges in advance, and then divides boundary...
In this paper, we develop a system to support learning of OpenFlow by visually associating controller configuration information and logical topology. In our system, the constructed topology is visually shown on a touchscreen display and a learner can easily confirm the topology. In addition, a learner can configure the controller by visual and simple operation using the touchscreen display. Therefore,...
Dynamic mechanical analysis (DMA) was carried out to understand the effect of the application of elastin on wound skin of hairless mice. Wound group, placebo group, and elastin group were selected to evaluate that effect. As the results of DMA testing, the wound and the placebo groups showed lower storage and loss moduli than the elastin group. On the result of loss tangent, there is a small difference...
The lack of caregivers in the field of nursing care is a serious problem in Japan, given the progressively declining birthrate and aging population. Because the lack of personnel in nursing care also affects qualitative aspects, careless care will lead to a decline in quality of life (QoL) of the care recipients. Therefore, with logistical support, such as from robots and ICT, it is expected that...
We have proposed a human detection system using UHF band TV wave. In recent years, a smart meter using 920 MHz band radio wave has attracted attention for developing HEMS. In this study, in order to detect human motion around a house, we proposed housing-site human detection system using the 920 MHz band radio. We investigated the characteristics of radio waves, confirmed the variation of RSSI (Received...
This paper tackles stalking problem that has become socially serious. Various approaches have been proposed to prevent becoming a victim of stalking behavior, but there are few ones to prevent becoming a stalker. In this paper, we proposed a mathematical model of stalkers' behavior. Next on the basis of the model, we proposed a game for education which provides simulated experience of stalkers. It...
With the spread of smartphones there is a growing demand for free charging space. That the rotation rate is reduced by a long period of time of use. In the fixed time charging is that there may not be charged until the charging amount expected. Current decreases in accordance with the charge amount, charging at a constant voltage was noted that the charging time is prolonged. In this study using a...
Live performances are increasingly appreciated using popular commercial audiovisual transmission systems, such as live viewing systems. A reality enhancement method for live viewing had been proposed. This paper describes an applause sound extraction method for automation of applause sound transmission and a simulation experiment using the sound source recorded live at the venue to assess the applause...
Today, governments and companies are prioritizing support for the elderly by providing IT services through tablets. Nevertheless, the elderly often face difficulties using tablets. For example, it can be difficult for elderly individuals to easily tap the screen. This research is intended to understand how we can help the elderly utilize these devices through a quantitative evaluation of tablet operating...
This paper presents a recursive oblique projector using the Gram-Schmidt process. The recursive construction of oblique projectors allows a receiver to prevail interference and noise environment in direct-sequence code-division multiple-access (DS/CDMA) system. When the number of the interfering users in the system increases or decreases, the oblique projector is recursively updated by the proposed...
It is important to provide sightseeing information to foreign people to promote tourism industry. However, in order to provide fresh information or intend for new sightseeing contents, we need to pay for the cost of contents updating and system migration. Therefore, we propose “Self-extending Type Open Data Platform” that can take in the tweet of the tourist automatically. This proposed platform has...
A method used for estimating the distance between objects in photographic images is the depth from focus (DFF) method. The method has reportedly been implemented many times using only image-side telecentric optical systems because a change in image magnification becomes a problem due to differences in focus positions. Therefore, there have been no examples of this method having been implemented using...
