  6. 6. Microsoft SurfaceAndrew Wilson6적외선 빛이 멀어질수록 빛이 약해지는 특성을 이용약 1,000만원 가량에 판매 중, 호텔, 카페, 개발회사 등에서 구입장비구성 Computer x 1, Infrared Emitter x 1, Infrared Camera x 4, Projector x 1
  7. 7. Perceptive PixelsJefferson Han7FTIRFrustrated Total Internal Reflection빛을 쏘았을 때 매질이 다른 곳에서 전반사장애(FTIR)이 일어나는 현상을 이용저렴한 가격으로 구현이 가능하여 대부분의 멀티터치 테이블에 쓰임사용화 시 걸림돌, Perceptive Pixels 사가 특허 보유
  8. 8. Wii Remote ProjectsJohnny Chung Lee8닌텐도 Wii 리모트 컨트롤러를 이용, 매우 저가이면서도 훌륭한인터페이스들을 선보임. 복잡하지 않고 비용을 많이 들이지 않고서도얼마나 훌륭한 인터페이스들을 만들 수 있는지 보여주고 싶었다는 조니리의 말.Low-cost Multi Point Head Tracking for VRFinger Tracking Foldable Display
  9. 9. Microsoft SideSight9Microsoft Research적외선을 쏘고 이를 받아들여 거리를 인식모바일 폰 양쪽 사이드에 어레이 형태로부착하여 멀티터치로 이용
