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...
This paper assesses the sense of presence for the 3D audio VoIP phone service with the binaural recording which is proposed by the authors by experiment. In the experiment, the authors use sounds recorded with actual heads, and evaluate the sense of presence and the sound source localization. The experimental results show the subjects can perceive high sense of presence by using our service. Moreover,...
Reducing large electricity consumption is a primary concern for researchers and practitioners in smart buildings. Peak electricity demand is the result of temporarily correlated energy demand surges caused by uncoordinated operation of subsystems such as air-conditioning, heating, ventilating and so on. It might cause severe issues such as service disruption and high cost of energy production and...
The authors propose a new parameter definition method and nail chip transformation method to superimpose nail chips onto dorsal-sided hand images with wrist rotation. Parameters for superimposing a nail chip on a fingernail are obtained using the center of gravity of the fingernail and the first and second principal component vector. A new transformation method was developed by including artificial...
A novel algorithm based on fading Kalman filter to estimate the state of charge (SoC) of Li-ion battery used in electric vehicles is proposed and validated in this paper. Online identification of battery's electric model parameters followed by open circuit voltage estimation by fading Kalman filter resulted in accurate SoC estimation. The experimental results obtained from actual driving cycle in...
The novel motion compensation method, called LIC (Local Intensity Compensation), approximates a current block using a linear combination of reference blocks. To reduce the bitrate of high quality images, sparse coefficients are preferable; then, a method applying sparse representation to the LIC has been proposed. A solver of sparse representation called AIHT (Accelerated Iterative Hard Thresholding)...
Energy consumption is a major issue for LDPC decoding. To save LDPC iterative process energy, early terminations are commonly used. Traditional parity check equation is used but has a growing complexity as the block size increases. This requires a large overhead in term of area. This paper proposes an ultra-low complexity early termination (ET) scheme with a small loss of bit error rate performance...
For interpreting the emerging process of visually induced motion sickness (VIMS), we propose a multi-timescale autonomic regulation model that consists of trigger and accumulation effects with different timescales. As validation experiments, fifteen participants viewed a 2-min-long first-person-view video section five times (total 10-min) continuously. Measured biosignals were the RR interval, respiration,...
Consumer electronics devices have a common point called integrated circuit (IC). Among the most advanced integrated circuits are the microprocessors which control everything from computers and cellular phones to the USB. In this paper, a novel manufacturing technique to enhance the passivation layer which protects the ICs is presented where a stronger passivation layer is made from Ni-TiO2 composite...
The function of depth perception may be related to the ability to perform vergence eye movements during the viewing of three-dimensional stereoscopic movies.
The control method of elevator system for peak power cut maintaining service performance has been proposed. Even if the method is optimal for the whole system, it is not always suitable for comfort of individual passenger. The paper describes the modeling and simulation of individual passenger transportation in elevator based on Mark Flow Graph.
In this paper, we present a home sleep care system to monitor function of activity measurement and sleeping position estimation via vision-based algorithms. The outcomes are integrated in a telecare middleware with a hierarchical software stack and visualized by a structural subsystem. Since smart TVs play an important role in home tele-healthcare system, we centralize and display additional sleep...
The objective of this paper is to evaluate pilots' body and physiological performance during their works using a large model sensor (tri-axial accelerometer and atmospheric pressure sensor) and a heart rate monitor toward safe harbors. The dis/embarkation experiment is carried out for the real pilotage. The results show that the largest acceleration 1.5–2.0 G appears during transfer from a pilot ladder...
In this paper the authors propose IPPITSU, an eyes-free, Braille-based text entry method for touch panels. In IPPITSU the user inputs a Braille cell by selecting the raised dot in it. In order to select the dots the user touches the regions corresponding to the raised dots by sliding the finger on the panel with one continuous stroke. IPPITSU is expected to be used by visually-impaired people. IPPITSU...
Many vendors or producers of consumer electronics provide web services for collecting data from consumer devices or accessing it from web applications. In this paper, we develop an approach for supporting users of consumer devices in building customized applications on demand. We use Webble technology, a component-based middleware system, as a base technology for distribution of visual components...
It has become easier to create a lifelog by using smart phones. Lifelogs can be used in several ways. However, some problems exist in memory recollection; as many lifelogs owned by a person are partial information, it is impractical to remember days themselves. Therefore, a lifelog sharing system for memory recollection is proposed. The system elicits related information from other people's lifelogs...
In this work, we propose a thermal-aware DRAM architecture and mapping for the multiple-channel three-dimensional DRAM system. A thermal-aware DRAM architecture with dual control and precharge circuits (Dual-CP) is proposed to avoid the accumulated temperature by the stacking of the control and precharge circuits. A thermal-aware bank remapping (BRMAP) is proposed to avoid the active banks in the...
Digital forensic investigation is the methodical restoration of evidences collected as a consequence of exploration of concrete happenings based on digital data. After analyzing all the historical approaches used in existing models, their merits and demerits are conferred and an Encapsulated Approach of Forensic (EAF) Model is proposed; which encapsulates all the phases of digital investigation. It...
Serious design of digital games is aiming at impact. Humans players may be affected by experiences in virtual worlds. Game designers anticipate potential experiences. Storyboarding is the technology of setting up conditions of future experience. Structural properties of storyboards correlate with potential human player experience. Those properties are named patterns. What shows when game play unfolds...
To provide a navigational tool to show a building's interior and other related information, we propose a three-dimensional computer graphics (3DCG) display system connected to the elevator's movements that can present a building's structural information. We altered the 3DCG's viewpoint according to the detected acceleration rate of the elevator and compared perceived acceleration rates through somatosensation...
