MobilePaperAccess is a wearable camera-glasses system with tangible user interface allowing mobile interaction. We access the digital information from a paper interface extending the input space. The system is devised to validate our concepts of Environment Dependent Interface (EDI) and Environment Independent Interface (EII), which focus on enabling people to access their personal data as well as public resources at any time and in any place. In this paper, we propose a continuum from physical interface to digital interface in relation with EDI and EII, and we present design, implementation and evaluation aspects of our MobilePaperAccess system. We compare two interfaces (EDI and EII) and three input techniques (finger input, mask input and page input).
