Advances in TV technology have enabled viewers to actively interact with the TV through interactive applications instead of just passively watching TV. Typically, a conventional remote control is shared by many viewers and it is difficult to accurately capture the individual interaction data from each viewer. It is also difficult to identify the context in which the interactions occur, e.g., to manage precisely who is present in the environment and what is being watched on TV. In this paper, it is presented a novel architecture that facilitates the capture of viewers' individual interactions and contextual data in shared TV environments. This architecture uses personal devices as secondary screen devices with the aim of identifying viewers and capturing their interactions with interactive TV devices. A work in progress implementation of this architecture is briefly reported as an audio-visual content rating system for interactive TV.

Power distribution protocol among power plants and consumers in power packet networks is proposed. According to this protocol, power packets are transmitted multipoint-to-multipoint simultaneously. Each power plant decides its power transmission destination depending on consumer demands and distances to them. The power transmission procedure is triggered by an occurring of a consumer demand. The power network performance is confirmed by computer simulations.

In this paper, we propose hardware efficient implementation of lifting based 2-D DWT and Sobel based edge detector for detail diagnosis in Wireless capsule endoscopy (WCE) in real-time. Architecture is developed based on the properties of the endoscopic images and the CMOS sensors. Proposed edge detection scheme works on the compressed DWT coefficients and offers 83.1 % compression ratio (CR). VLSI implementation of the proposed scheme consumes only 17050 standard cells.

In this paper, we propose a multi-layered Probabilistic Latent Semantic Analysis (PLSA) model for personalized video summarization problem based on time synchronous comments offered by multiple users. Preliminary evaluations performed on an animation series of 624 minutes long with 12212 users show that the proposed model is able to captures the relationships among the preference of each individual user and the various video events, therefore is able to generate personalized summaries of unseen videos for different users.

Recent years have seen the popularization of model based development (MBD) using models based on block diagrams. In many mechatronics systems, including automobile engine control and the brake control, a closed loop control is used to manage controls based on feedback data from control target objects. In order to develop a closed loop control using model base, a plant model that simulates the behavior of the control target plant is needed. This control model and the plant model are used throughout all the model based development processes. This paper discusses case examples in which these model based development technologies are applied to energy system developments that combine inverters and converters. We constructed a model house called “Smart Cell” as a place to demonstrate the energy system. We will introduce the Yokohama Smart Community [1] the instigators of this demonstration project. This organization aims to establish technologies that can make better use of natural energy.

This study proposes a new adaptive image enhancement algorithm based on contrast-tone mapping curves. In the proposed method, an image is divided into several blocks and a histogram is calculated for each block. An appropriate mapping curve is calculated from the shape of the histogram for each block and quasi-regional contrast enhancement can be obtained. The experimental results demonstrate that the performance of the proposed method is very similar to that of the Retinex method, whereas the computational time required is much lower than that with the Retinex method. This technique can be applied to consumer electronics devices such as digital cameras and smartphones.

To capture and record a multi-view video is inconvenient due to needing mechanism for synchronization between cameras and computational cost for video coding. This paper presents a multi-eyed network camera which has five fixed HD camera modules and a gigabit Ethernet port. Only one LSI controls the camera modules and encodes all captured videos. To reduce computational complexity and keep synchronization, compressing is based on distributed video coding, and multiplexing is an extension format of the H. 264/MVC NAL structure. Implementation results show that all functions are integrated in the LSI and that the synchronization is kept after transmitting.

In this paper, we evaluated the characteristics of the bone-conducted sound propagation in the human head through computer simulation using a reduced head model with finite element method. The model was made of three spheres, which represent the skin, skull and brain, and the brain was represented by the water for simplicity. The step response of the head was investigated to show that the sound propagation would be generated in the form of longitudinal and bending wave through the head. From the simulation results, the sound speed of the longitudinal and bending waves were approximately 1500 m/s and 260 m/s, and the latter was compatible with the previously measured sound speed of bone-conduction.

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, and blood pressure time-series to estimate the low-frequency (LF) and high-frequency (HF) power components and the LF/HF ratio. Then, we determined the trigger points and the sections that produced some sensation. The results showed that VIMS is first induced by specific trigger factors and increases depending on individual differences in autonomic regulation. The multi-timescale autonomic regulation model, which has independent coordinates for presence and VIMS and represents the short- and long-term effects, seems preferable for interpreting VIMS.
