Nagoya is located in the center of Honshu, the main island ofJapan, with a population of 2.24 million. Thanks to the rich water
resources of the Kisogawa, Nagaragawa and Ibigawa Rivers, thefertility of the land due to the blessings of the rivers, and otheradvantages such as good transportation links, the people of
Nagoya have lived affluent lives since early days.
Nagoya has a long history and is the birthplace of three notablefeudal lords, Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa
Ieyasu. In addition, traditional industries like ceramics and textiles,
and today’s key industries like automobiles, aviation and machine
tools have developed, and Nagoya plays an important role inJapan’s industrial society.
Chubu Centrair International Airport is the gateway of Central
Japan to the sky, and has many international and domestic routes.
Centrair is linked to Nagoya by an excellent transport network,
taking 28 minutes by train or 30-40 minutes by car. Nagoya has
good access to Tokyo, Kyoto, Osaka and all other areas in Japan.
Participants can enjoy a diverse and exciting range ofpost-convention activities taking advantage of Nagoya’s location.

Zero-zero-birefringence polymers which exhibit neither orientational
nor photoelastic birefringence were successfully prepared with multiple
compositions in a quaternary copolymerization system. Therefore,characteristics other than birefringence can be controlled appropriately
for use applications such as polarizer protective ﬁlms and light guideplates for polarized laser backlight, while maintaining zero-zerobirefringence.

A wall charge adjusting pulse is adopted to reduce the wall charges
accumulated on the scan and display electrodes. This allows a use ofhigher scan voltage, resulting in low data voltage and wide operatingvoltage margin. 40 V data voltage and 15.6 V margin are obtained with
0.67 µs scanning speed.

Temperature Dependence of Address Discharge
Characteristics for Write-Address and EraseAddress Methods in AC PDPs
M. Yoshita, Y. Hashimoto, T. Shiga
Univ. of Electro-Commun., Japan

Exo-electron emission increases at high temperature, thus writeaddress discharge delay becomes shorter and wall voltage after
addressing becomes lower due to recombination. Exo-electron
emission does not inﬂuence the erase-address discharge delay. But thedelay becomes larger at high temperature since the other priming
particles reduce the wall voltage before addressing.

spatial frequency and contrast of objects in forward view. We preparedfor background board with stripe pattern. Spatial frequency andcontrast of the background board which were affected by the raindrops
are possible to calculate by proposed method.

This study aims to examine the potential measurement of fatigue
levels. Special focus is on deoxygenization of blood hemoglobin
strongly related to fatigue from exercise. The possibility to discriminate
fatigue from normal state was examined using a hyper spectrum
camera (HSC).

Meijo Univ., Japan

Although driving ability decreases with advanced age, few elderly
people recognize the decline in their own visual, cognitive and decisionperformances; this lack of awareness is a major cause of accidents.
This paper presents a method for detecting cognitive decline in elderly
driver by driving performances to prevent serious accidents.

AUTO

This paper describes a method for detecting if a driver can drive safely
by measuring pupillary light reﬂex to active photic stimulus before he/she starts driving. We conducted some experiments on drunk andsober drivers, and conﬁrmed that our index “63% dilation time” iseffective to classify those drivers.

Japan faces “super-aged” society, and the number of accidents caused
by elderly drivers is increasing. Although driving ability decreases withadvanced age, few elderly people recognize the decline in driving
ability. For this research, we develop the driving simulator whichquantitatively measures necessary driving ability.

Cognitive Characteristics for an ARIS (Augmented
Reality Interface System) Applied to an Automotive
Head-Up Display
W. Kaneko, R. Ando, S. Okabayashi
Meijo Univ., Japan

Assuming that the ARIS is applied to automotive display equipment, weinvestigated cognitive characteristics in terms of how fast andaccurately displayed information can be recognized. It was also veriﬁedthat ARIS shows markedly better characteristics when both the driverʼsoutward forward view and the displayed images are more complex.
