대부분의 인터랙션은 1:1 scale view에서 가능하다.

오버뷰에서는다른 뷰들을 panning하기위해 인터랙션이 제한된다.

Qualitative Results

서로 다른 논의 전략을 가능하도록 한다.각자 특정 역할(만들기, 자료공급, 틀 잡기, 토론, 의사결정)을 했다. 2, 3번째 세션에서는 이 역할들이 shift

협업을 지원한다.

“(This application) is interesting, something new. It’s like teamwork.” [P4]

“It’s collaborative, it gets more things out of everybody. It's good at discussing things, you get new ideas with these trees.” [P5]

But한 번에 하나의 노트만 만들 수 있는 것은 제한적화면이 작아 다른 사람이 작업할 때는 안보인다.테이블을 옮기는것보다 노트를 옮기는 것이 더 직관적

뷰를 나눈 것은 좋았다.

gesture가 좋았다.(delete)

Conclusion 6

15

1. 프로토타입 제작 -> 평가

2. gesture를 통해 다른 디바이스와의 연결과 접근 각도 문제를 해결했다.

3. Position tracking sensor를 이용해 추후 연구를 시도할 것.

Discussion +1. 프로토타입의 경우 글보다 영상이 좋다. 그러나 논문화가 숙제.

2. SSIs는 같은 공간에 있는 것을 전제로 한다. 그런데, 왜 굳이 모바일로.

종이보다 무엇이 더 편한가논의+서기 프로젝터와 무엇이 다른가

3. 면대면 comm의 장점이 많은데, 오히려 이러한 부분을 방해할지도.

4. 프로토타입 개발시 논문은 이렇게..
