In this paper, a finger pose estimation method is presented. A direct use of fingers is useful in some applications which require handling of 3D position information. Our finger pose estimation method exploits anatomical constraints on finger motion and ring-shaped markers to achieve simple and practical measurements applicable to daily life situations. The use of anatomical constraints ensures that no exact placement of the markers is required.
Laboratory experiments were conducted to investigate the run-up of internal solitary waves (ISWs) on steep uniform slopes in a two-layered fluid system with a free surface. A 12 m long wave flume, which incorporated a...

Risk prevention and alarm are crucial for home care of aged people who live alone. In this paper, an acousticallyanalytic approach is proposed to extract behavioral patterns for modeling and monitoring living activities. An experimental environment was established for collecting sound tracking data of behaviors from daily activities. Each sound tracking data was transcribed to the corresponding sound event sequences by caregivers and psychologists. A living activities mining algorithm is applied to extract meaningful sequences of sound event as behavioral patterns. Then K-means algorithm is adopted to classify events into several fuzzy clusters relating to living activities for modeling behaviors in daily activities. An experimental database consists of 150 sound tracking data was established by collecting three guided behaviors included rolled out of bed to drink water, go to the toilet and watch the fish jar from 5 subjects in two weeks. 476 meaningful sequences of sound events were explored and clustered into 32 quasi-activities. These quasi-activities were further concluded into 5 kinds of behavioral patterns for modeling living activities. The preliminary result shows the potential for modeling and proactively detecting abnormal behaviors or changes of the aged.

IETF(Internet engineering Task Force) proposed the management mechanism of NEMO (network mobility) to support network mobility. The mobility management of NEMO is an extension of mobile IPv6 (MIPv6), and it inherits also all the drawbacks of MIPv6 such as inefficient routing, high handover latency, packet loss rate, and so on. The purpose of method which is based on the public transportations (e.g. Train, MRT, Bus etc.) with fixed path as NEMO application solved the handover latency problem and packet lost problem. We propose a seamless handover scheme with pre-registration to solve these problems. The proposed handover scheme can decrease handover latency and packet lost in session for NEMO. The aim is to procure seamless communication when the whole network is movement.

A human centered pragmatic approach to the design and implementation of a vibrotactile belt is presented in this paper. Based on (a) extensive usability feedback we've collected over the past year, and (b) a thorough survey of existing design guidelines from the literature, we propose a set of design guidelines for the development of haptic belts that can span seamlessly across various applications. These guidelines cover three important aspects for haptic belts: functionality, performance and usability, which are vital for longitudinal use by end users. Taking a human-centric approach from these design guidelines, we demonstrate the construction of a wirelessly controlled haptic belt design that is versatile, usable and practical. Implementation details of the belt are given, along with a preliminary usability study and a brief review of some of the important application areas of haptic belts. Results from the usability study reveal that participants were very pleased with the proposed haptic belt, and found it to be easy to wear and use.
