A position guidance system for the blind using lighting apparatus : An improvement of the optical characteristic

MATSUSAKA Nohiriro, MAKINO Hideo, WATANABE Reiji, YAMANOUCHI Hiroaki, MAEDA Yoshinobu, ISHII Ikuo

IEICE technical report. ME and bio cybernetics 104 ( 500 ) 17 - 20 2004.12

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

To develop a universal location guidance system for the blind, we are studying an indoor location positioning method. For such purposes, several new information transmission methods using a fluorescent light were proposed by Steven Leeb et. al. However, in the case of digital data transmission using frequency modulation, there are difficulties for high-speed data transmission because of brightness fluctuation in fluorescent light. In this paper, using a guidance system developed by our group, we examined the position data transmitted at the speed of 4800 bps, and observed a fluctuating receiving signal in the speed of 9600 bps. Moreover, in case information is transmitted, we describe flickering generated from a fluorescent light.

YAGI Eiji, MAEDA Yoshinobu, MAKINO Hideo, HIRONO Mikihiko

IEICE technical report. Circuits and systems 103 ( 569 ) 41 - 46 2004.1

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

Neurons and cardiac cells transmit the physiological information by propagating the action potentials. We proposed an electronic circuit oscillator model especially for the cardiac cells. The diffusively coupled system of these hardware models shows the acceleration phenomena, whose periods get shorter than the period of each isolated system. In this report, we investigated, using the hardware models, the needed power consumption to cause the acceleration phenomena. As a result, we found that the power consumption could be reduced through the coupling of the isolated systems, though the acceleration phenomena were observed.

Experiment and Evaluation of a GPS Mobile Phone and PDA in a Speech-Output Guidance System for the Visually Impaired

HIGAKI Hiroyuki, MAKINO Hideo, WATANABE Reiji, TETSUMOTO Hideo, MAEDA Yoshinobu, ISHII Ikuo

IEICE technical report. ME and bio cybernetics 103 ( 327 ) 61 - 66 2003.9

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

A GPS (Global Positioning System) and GIS(Geographic Information System) based speech-output guidance system has been developed as the assistive technology for the visually impaired. In this report, to develop a practical speech-output guidance system for the visually impaired, we developed novel software which enables location data to be input by a visually impaired person. We also developed the speech-output data management system. Here a user is able to input location data and able to receive speech-based guidance using a GPS mobile phone or a PDA that has a GPS receiving unit. Moreover, the speech-output data management system enables input and output of data according to a user's coordinate position on a digital map. Such maps now cover the entire area of Japan. Using a GPS mobile phone, our experimental work suggests that a user can receive speech-output guidance within 15 seconds, automatically.

Consideration for individual identification from face-image and hand-image using multivariate analysis

HAYASAKA Shuichi, MAEDA Yoshinobu, MAKINO Hideo, ISHII Ikuo

IEICE technical report. ME and bio cybernetics 101 ( 533 ) 67 - 74 2001.12

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

We addressed the basic research of individual identification using the face-image and the hand-image, which are taken from both the visible gain region(VGR)and the near infrared ray region(NIRR). First, we derived the features of the image from-second-order local auto correlation features. Second, we identified a given image using the several reference images from point of view of the multivariate analysis. We obtained the NIRR images by a CCD camera, an optical filter, and an incandescent lamp. We verified experimentally the individual identification from those Images of three persons, and, we checked that the IRR image is effective for individual identification.

Improvement of resonant communication system in an Implantable Stimulator

TORIKOSHI Yoshio, MAKINO Hideo, SATO Eiichi, MIKAMI Nobuhiro, MAEDA Yoshinobu, ISHII Ikuo

IEICE technical report. ME and bio cybernetics 101 ( 533 ) 81 - 88 2001.12

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In a cardiac pacemaker, it is difficult to obtain an electrocardiogram(ECG)using long-term real-time telemetry, when power is supplied by an internal battery. Therefore we have considered the resonant communication system, which reduces the consumption of the internal battery, using an implantable stimulator for cardiomyoplasty. Because resonant frequency changes and communication sensitivity fall, with change of communication between the inside-body equipment and the outside-body equipment. The external device which can choose the optimal carrier for communication distance was developed, preventing a fall in communication sensitivity. Resonant communication was estimated by a device distance within 65mm and a baud rate of 2400bps.

Application of an invisible bar code to Augmented Reality : Object position detection and speech guidance method

YAMAMOTO Satoshi, MAKINO Hideo, MAEDA Yoshinobu, HIRONO Mikihiko

IEICE technical report. ME and bio cybernetics 100 ( 330 ) 59 - 66 2000.9

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

An augmented reality is a technology that presents information by combining virtual objects in the real world. We have examined a method that recognizes some objects and presents their information to users. Concretely we have developed an object guidance system using a CCD camera and an invisible bar code, which one cannot recognize in normal circumstances. The object guidance system recognizes the invisible bar code. Detailed description of the object is provided through speech. We confirmed that at least three objects on the desk were exactly identified and that the detailed information about each object was described by speech. Then it took about 3.8 seconds to detect three barcodes, and about 7.8 seconds to decode each barcode. The invisibility of the barcode maintains the integrity of the object, whereas visible bar codes tend to dominate the design of objects. We expect that this system can be applied to not only augmented reality but also an assistive technology for the visually impaired.

An Outdoor Guidance System using GPS for Visually Impaired People [II] : Guidance using FM-DGPS

TANO Eiichi, MAKINO Hideo, MAEDA Yoshinobu, KITAMURA Yasuhiro, MARUYAMA Atsushi, IKARASHI Akira

IEICE technical report. ME and bio cybernetics 100 ( 98 ) 101 - 108 2000.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

We have improved the outdoor guidance system for visually impaired people using a FM-DGPS and our prototype portable unit. First, we had our system possess the following two functions. One was a telephony type, the other was a portable type. We regard the system, which the mobile station obtains the geographical data via a telephone circuit, as the telephony type. When the mobile station has both the GPS receiver and the geographical database, we regard it as the portable type. Second, while we walked around our campus, urban and rural areas, the measurement error of the FM-DGPS was about three meters on average and ten meters at most. Finally, we compared the radiobeacon-DGPS with the FM-DGPS in view of evaluating accuracy. Also, we verified that the DGPS, using our GPS receiver and the radiobeacon was useful for our Guidance System.

Consideration for bar code position detection using a neural network with mutual inhibitions : Application to work assistance for visually impaired

HAYASAKA Shuichi, MAEDA Yoshinobu, MAKINO Hideo, YAMAMOTO Satoshi, SEKIYA Yasushi

IEICE technical report. ME and bio cybernetics 100 ( 98 ) 109 - 116 2000.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

We have developed an assistive system for the visually impaired to recognize functional parts of objects. The necessary information for the visually impaired is encoded in a two-dimensional (2D) code that put on the object. In our study the 2D code is "invisible" in the sense that it is hidden in the background design, though it is visible in the near infrared spectrum. Therefore, we cannot recognize it through our naked eyes. We extended the faculty of our system in this report so that the system could recognize successively the several 2D codes. To this end, we used an artificial neural network in which each neuron model is connected by means of mutual inhibitions. A static image (640×480 pixels) obtained by the CCD camera was given to the neural network composed of 357 Nagumo-Sato neuron models. The neural network was set so as to overspread the image. When the network parameters were regulated at appropriate values, the corresponding neurons to the location of 2D codes could generate randomly a bursting excitation their turns. A 2D code is 1.5×1.5cm in area. The distance from CCD camera to 2D code is 40 cm. When initial values of the neuron models were identical, we confirmed that our system could detect five 2D codes during forty seconds by using numerical simulation (Pentium II prcessor, 450MHz).

Therefore we have considered the resonant communication system, which reduces the consumption of the internal battery, using an implantable stimulator for cardiomyoplasty (Sato et al.1997). In this paper we report on an improved telemetry, and also the monitoring of ECG in real time. Resonant communication was estimated by a device distance within 30mm and a baud rate of 2400bps. The ECG was displayed on the external programmable device under a resolution of 8 bits and a sampling frequency of 240Hz. Current consumption was within 1mA in a trial device.

An Outdoor Guidance System using GPS for Visually Impaired People : Increased accuracy using FM-DGPS

TANO Eiichi, MAKINO Hideo, MAEDA Yoshinobu, PARKES Donald Nicholson

IEICE technical report. ME and bio cybernetics 99 ( 82 ) 35 - 40 1999.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

A GPS provides information on location, using signals from Global Positioning System satellites. Elsewhere we have discussed an outdoor guidance system using GPS for visually impaired people. In our earlier reports the measurement error was over l00 meters, using a stand alone GPS receiver. Now measurement error can be reduced to 10 meters at most when using FM-DGPS and our prototype portable unit. Our system was composed of two stations. A visually impaired traveler with a GPS receiver formed one of the stations. A personal computer acted as the base station. The stations were linked by telephone enabling the visually impaired traveler to receive guidance information. Here we report on the use of a GPS receiver and palm-top computer by visually impaired people.

A Method for Displaying High Definition Images in Distance Learning : The Tuition of Children in Hospital

ABE Hirotaka, MAKINO Hideo, MAEDA Yoshinobu, ISHII Ikuo

IEICE technical report. Education technology 98 ( 563 ) 47 - 54 1999.1

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

When students have to study using distance learning procedures, for instance children who are in hospital;it may be difficult for them to receive 'CLEAR'images on their 'BLACKBOARDS'. In this paper, we present ways to display 'CLEAR', high definition images. The procedures used to achieve this objective are discussed. Specifically, the whole 'blackboard' is not used but is divided into several smaller images using a video camera. We then use the 'entropy of images' to select a template to reconstruct the final image using pattern matching. Our experiments suggested use of a 40×40 pixel template and high entropy, as optimal in a image(640×480 pixels). We conclude the paper by describing an application using a school for children with special needs.
