6. CyARM-interactive device for environment recognition using a non-visual modality

Author

Abstract

金沢大学融合研究域融合科学系 / 金沢大学大学院自然科学研究科情報システム, The purpose of this research is to develop an interactive device for environment recognition, which uses senses other than vision. At present there is no interactive device with which a person who is visually handicapped can gain an intuitive impression of the external world. Our device, which we have named CyARM, has a mechanism that controls the motion of a visually impaired person's arm according to information about distance gathered by an ultrasonic sensor. We refined the features of CyARM through experimentation. The user can identify not only the existence of an object, but also its form. © Springer-Verlag 2004.

Abstract

SUMMARY: Line‐of‐sight (LoS) calculation, or detecting where the user is looking at, is expected as a new type of user interfaces, with including the phenomenon of rapid eye movement, so‐called saccade. However, real‐time tracking of saccade is difficult with the conventional image processing systems for their long processing time and latency against the speed of saccade. In this paper, we describe the design of the high speed, low latency LoS calculation image sensor, as well as its preliminary evaluation results. This image sensor has a capability to track the saccade at high frame rate, and generate the LoS calculation results with minimum latency for real‐time tracking. [ABSTRACT FROM AUTHOR]

Abstract

金沢大学理工研究域電子情報学系, Numbers of devices are distributed in the environment in wearable and ubiquitous computing systems, and all of such devices need power supply and communication ways as well as flexibility of placement. Both wireless and wired communication systems intrinsically contain the problems in power supply or flexibility of placement. In this paper, we introduce the flexible network infrastructure for wearable computing systems, named as TextileNet, and experimental results of its evaluation. TextileNet uses the wear both of sides of which are made of conductive fabric as electrodes. On this year, the power is supplied from a battery, and the devices are attached by sticking so that electric contact can obtain the sufficient power and communication way on the wear's surface. This paper describes the implementation and evaluation of the TextileNet system. © 2006 IEEE.

38. Prevalence of mitochondrial gene mutations among hearing impaired patients

Abstract

The frequency of three mitochondrial point mutations, 1555A→G, 3243A→G, and 7445A→G, known to be associated with hearing impairment, was examined using restriction fragment length polymorphism (RFLP) analysis in two Japanese groups: (1) 319 unrelated SNHL outpatients (including 21 with aminoglycoside antibiotic injection history), and (2) 140 cochlear implantation patients (including 22 with aminoglycoside induced hearing loss). Approximately 3% of the outpatients and 10% of the cochlear implantation patients had the 1555A→G mutation. The frequency was higher in the patients with a history of aminoglycoside injection (outpatient group 33%, cochlear implantation group 59%). One outpatient (0.314%) had the 3243A→G mutation, but no outpatients had the 7445A→G mutation and neither were found in the cochlear implantation group. The significance of the 1555A→G mutation, the most prevalent mitochondrial mutation found in this study of a hearing impaired population in Japan, among subjects with specific backgrounds, such as aminoglycoside induced hearing loss, is evident.
