Abstract

In a ubiquitous computing environment, people more and more become to use multiple displays. When using such ubiquitous displays, it is needed for users to seamlessly interact with the displays for a certain content. In this paper, we propose a seamless interface that allows users to see photos across multiple displays. Many photos can be displayed on a screen at the same time because they are shown in 3D space. And a group of photos is represented using a cube metaphor. A user can manipulate photos directly using a touch screen and also see the photos continuously using PDAs when the user moves to other places. In addition, the user can interact with the photos seamlessly using another display. The developed system was designed to interact according to user's movements and not to draw user's attention too much as a kind of ambient display. Using RFID and ultrasonic sensors it recognizes a user and the user's proximity to the display, and then automatically determines the screen image and the user interface accordingly.

유비쿼터스 컴퓨팅 환경으로 변화됨에 따라 사람들은 점점 더 많은 디스플레이를 이용하게 된다. 이러한 유비쿼터스 디스플레이 환경에서는 사용자가 컨텐츠에 대해서 디스플레이들과 지속적으로 인터랙션 할 수 있는 방법이 필요하다. 본 논문에서는 사용자가 여러 디스플레이를 오가며 사진을 감상할 수 있도록 연속성을 갖는 인터페이스를 제안한다. 제안 시스템은 3차원 공간상에서 사진을 보여주기 때문에 많은 수의 사진을 한 화면에 동시에 보여줄 수 있고, 큐브 메타포를 사용하여 여러 장의 사진을 그룹화 한다. 사용자는 터치스크린을 이용하여 사진을 직접 조작할 수 있으며, 다른 장소로 이동시에도 휴대하고 있는 PDA를 통해 컨텐츠를 지속적으로 이용할 수 있다. 또한 다른 디스플레이를 통해 연속적으로 인터랙션을 할 수 있다. 개발된 시스템은 사용자의 묵시적인 움직임에 따라 반응하면서도 주의를 지나치게 집중시키지 않는 앰비언트 디스플레이 형태로 설계되었다. RFID 센서와 초음파 센서를 이용하여 사용자 신인 및 디스플레이와의 접근거리를 인식하고, 사용자와 디스플레이의 근접도에 따라 보여 질 영상과 인터페이스를 파동으로 결정하게 된다.
