Social network service (SNS) offers a convenient way for users to share their daily experiences and significant life events with family, friends, etc. However, the notion of SNS fatigue posits that use of social media can trigger anxiety and loneliness. In particular, the tighter and stronger social bonds that SNS seems to support increase such fatigue. Thus, this study proposes a method for providing...
Highly interactive educational contents using games are widely used, and objective evaluation of these real-time is required. In order to do this, we recorded brain waves under several interactive tasks and game situations in subjects and tried to analyze them. As a result, we focused on the proportion of beta wave components, which suggested the possibility of being able to distinguish between simple...
When shooting through a glass window, a foreground scene may be reflected in the captured image. The elimination of this reflection is useful for protecting the privacy of surrounding people, improving image recognition accuracy in robot vision, etc. In this paper, we propose a reflection-removal method based on sparse/no-sparse gradient regularizations with gradient constraints. Experimental results...
This paper suggests an upper limb motor and proprioception assessment system using head mount display (HMD) and virtual reality (VR). We designed 1-DOF reaching tasks with various distances. Each task was performed while the VR controller, which represent a user's position of end-effector, was either visible (V) or invisible (NV). 6 stroke patients with low upper limb function and 7 normal subjects...
This paper proposes an in-vehicle power line communication (PLC) system which provides an in-vehicle communication for the video and vehicle messages transmission as a reliable alternative networking medium. The proposed in-vehicle PLC system adopts an existing in-vehicle 12-V battery power system, which means we don't need an external DC power supply for in-vehicle communication equipment to achieve...
The increase in the amount of program code in electronic control units (ECUs) in vehicles has caused an increase in the number of firmware updates after sales, which stems from bugs in the program. In this situation, automakers are considering introducing over-the-air firmware update technology that has been used in the consumer electronics field. In this paper, we propose incremental update methods...
Recently, emotion expression of robots have been considered as a very important factor during communication between robots and human. As ways of emotion expression, there is not only verbal information but also nonverbal information such as facial expressions and body movements. In this paper, we focus on body movement, which is one of way for a robot to express its emotions. We propose an emotions...
Many Internet of Things applications provide methods to create mashup services with if-then-else approaches due to its simplicity. When a number of mashup services are increased, it may be suffered by service conflict, that is, mashup services may perform opposite actions or abnormal behavior at the same time. To overcome this issue, this paper proposes the concept of context descriptor to detect...
In recent years, because of internet technology and the promotion of open science, it has become possible to obtain information about research progress. Nevertheless, many steps must be taken to collect such information exhaustively. Even when one wants to know only a summary, one must expend much time and effort. For this study, we propose a system that collects information about each laboratory,...
A life log is a record of human life and behavior as digital data. In recent years, it has become possible to collect easily life logs by wearable devices. There is reflection of information as one of usage of these life logs. Among them, reflection by images is easy to understand. However, when recording for a long time by automatic photographing, the number of images becomes enormous, and it is...
IDS(Intrusion Detection System) is widely used. However, IDS has a problem that it is difficult to manage its operation because of occurring a large number of alerts. As a general usage of IDS, it is known that a certain threshold value is set and only the alerts exceeding it are reported. Generally, the threshold values are determined based on the subjectivity of administrator. Therefore, we have...
Under Real-Time Pricing (RTP) the cost per kWh varies with time as a consequence of the changing supply and demand conditions in the market. Customers that are able to shift their electricity consumption patterns can reduce their costs by using their devices when price is low. This requires a smart power outlet that can turn itself on/off based on price, and customer preferences. This paper is about...
The supervision of rehabilitation exercises is crucial for a successful therapy. Due to a lack of therapists, technical assistance systems have recently come into focus to assist patients during their exercises. Latest research proved that characteristic motion errors can be detected by using the Kinect skeleton joints in connection with Incremental Dynamic Time Warping (IDTW) and machine learning...
This study describes an User-Centered approach to design an User Interface (UI) to support daily activities of people with dementia. Such interface is the main hub of a home automation system able to monitor the house and reminds to the users some information when they approach the door to leave the home. In order to involve end users in UI evaluation at the end of the first stage of the design process,...
Wireless sensors networks have an enormous potential for measuring environmental parameters such as those found in building or residential scenarios. The range of available sensors is not only limited temperature, gas, humidity or presence detection, but even power grid analyser can be integrated. This work aims to develop a Home energy management system for a residential scenario or nanogrid. Inside...
Nowadays, people have to face many challenges In order to become familiar with all the functionalities of electronical devices. The training process becomes thus essential, especially when we are referring to consumer electronics created for people with disabilities. Our paper presents the importance of training visually impaired people for an advanced sensory substitution device. By using the advantages...
Most home sensor devices nowadays is based on low data rate and on-demand routing protocol such as Ad hoc On-demand Distance Vector (AODV). This routing protocol has less overhead and good efficiency in term of delivery ratio and bandwidth. AODV has two phases the route discover phase which discover route to the destination devices based on the shortest and the freshest hop, and the data delivery...
Process of detailed testing and verification of all automotive embedded software components generates detailed reports about each segment of tested electronic control units (ECU). The very first group of tests in this process is Acceptance tests, and one of the most important tests in this stage of testing and verification is interface check of the software component. The interface check must ensure...
This paper proposed a monocular vehicle detection for forward collision warning system. We use the active-learning framework to train a cascade classifier and use a two steps vehicle detection. We used five test data to quantify our detection performance, analyzing the two-stage vehicle detection improvement, and the overall detection rate and the false detection rate. In a good light condition, the...
This paper proposes a lane estimation algorithm on roads where lanes are not visible due to fading or bad weather conditions. The proposed algorithm is conducted by utilizing the road width and remained lines on roads. The results indicate that the proposed algorithm can estimate lanes in heavy rains and nights.
