## 【Abstract】

The Pupil detection device and method was invented by Prof. Ebisawa, Shizuoka University. This system is able to use not only for the "Pupil Mouse" of personal-computer but also the useful interface in an industrial system. Avoiding from the accident by drowsiness is the important problem for the every transportation company. Hamamatsu Optronics Cluster collaborates with Hitachi group find that this system will be the best solution for the safety and reliable driving. Yazaki Meter Co. success to attaching this system in the cabin of truck and lorry. This sure to contribute to the efficient logistics.

## [Summary of the technology transfer]

## Technological Impact

However the cockpit of a truck is dazzle or darkness in every driving situation, the function of the drowsiness sensor should be detected the eye and alert to the driver. The basic technology of “pupil mouse” is possible to detect the exact position of pupil in any condition of when light irradiation is changing in rapid or slow and any vibration. We find this robust and smart method of pupil position detection is the best solution for the drowsiness sensor.

## ●Social Impact

Our drowsiness sensor was evaluated before the test production. In an actual driving situation, in a day and night or every condition, all results revealed the reliable and safety for driving. Especially, it is highly useful in night long driving. This system brings not only a happiness of a driver but also the wellness of the traffic company. At the time the validity for a truck run will be recognized, it is expecting, this drowsiness alarm is attached to every machinery that need human watching or operation.

## ●Special Features of the Collaboration

The many invents from the researcher is spreading to the several application and the many patent filing. Hamamatsu Optronics Cluster makes collaboration of the transportation company and the car drive recorder maker. Accumulated each experience and technique bring our joint business to success, and it will bring the innovation to the logistics.

## Project Background

Need for an alert sensor for drowsiness meet the pupil position detecting system using the robust method. This joint development was success by the experience of the special field in each company.

## Turning point in the Project

The seeds from research should not bring to a single application, rather are seeking to every chance to meet the needs of social demand. For this, our results and patents are forming with the development of industrial company. In this way, the basic patent is created in university, is concreted in companies, and made this actual business.
