This paper proposes extensive applications of virtual collaborative space in order to enhance the efficiency and capability of Digital Campus. The usability of Digital Campus has been experimented in different learning environments and evaluated by questionnaire as that the presence technology and a sense of solidarity influence the participants' satisfaction in both real and distant education. The achievement scores and communicability rates were also higher for those studied in the classroom with 3D virtual space. In the efforts of constructing a more efficient Digital Campus model, newer and additional functions and applications of virtual collaborative space have been explored and experimented to expand educational opportunities and possibilities without limitations and restrictions in terms of time and location, in accordance with the advancements of mobile devices and the expansion of ubiquitous environments.
