본 연구는 인지재활훈련을 위한 새로운 인터페이스 개발에 관한 것으로 물리적인 실감 객체와 디지털 테이블 탑 인터페이스를 활용하여 사용자가 보다 직관적이고 쉽게 인지재활 콘텐츠를 이용할 수 있는 실감 테이블탑 인터페이스를 제시한다. 일상에서 사용하는 사물의 형태와 쓰임새를 모방하여 제작된 실감 객체를 활용하여 사용자는 직관적으로 쓰임새를 이해할 수 있도록 하였고, 실감 객체에 내장된 센서들은 사용자의 제스처를 인식할 수 있도록 하였다. 테이블탑 인터페이스는 테이블에 올려놓은 물체를 인식하고 이에 대한 화면 피드백을 제공한다. 본 연구에서는 실감 테이블탑 인터페이스의 프로토타입과 함께 프로토타입에 사용된 인지재활콘텐츠를 소개한다. In this paper, we present a novel interface, tangible tabletop interface(TTI) that consists of tangible object and digital tabletop, for people with cognitive disorder to interact with digital contents without mental load. They can easily use the interface manipulating tangible objects that imitate the form and the usage of daily living things. The digital tabletop interface recognizes the position of tangible object and gives feedback on the display. This paper describes a prototype of TTI and digital contents for cognitive rehabilitation.

This study examined the field of view of older drivers based on their eye points. The subjects were 25 people whose age was over 65 years and 10 contrasting subjects on their 20s. For the experiment, we expanded the width of the A-pillar of a test vehicle. With a measuring apparatus designed for the study, we analyzed 3 axes of coordinates from glabella to a fixed point of the vehicle that would be used as CAD data of vehicle design. Result shows that average eye point of the older subjects was located significantly farther ITom the seat than that of the 20s approximately by 3 1.62㎜(p=0.05). It was also found that the Binocular FOV was not significantly different between the older subjects and the 20s(p=0.85), and the effect of the width of the A-pillar on the FOY could not be found. We also measured the left and right side of the Ambinocular FOV of the older subjects. It was found that the older subjects had much wider visual angle than the 20s by 2.84 degree (F=4.78, p=0.01) on the left side, while the 20s showed significantly wider average angle than the older subjects by about 4.88 degree (F=4.78, p<0.05) on the right side. The results of this study can be used to improve the FOV based on the optimal eye points when designing a vehicle for older drivers.
