Because of the advances of computer hardware and software, Computer Aided Instruction (CAI) makes learning effective and interesting through the use of interactive multimedia technology. Recently, Augmented Reality (AR) technology has begun to surge as a new CAI tool because of its ability to create tangible and highly interactive user interface. In addition, recent studies have shown that the learning content as well as the participation of learners in learning activities can greatly affect learners' learning performance. However, studies of the integration of PC DIY (Personal Computer Do It Yourself) learning with AR technology are still few in current literature. Therefore, this study proposes an AR learning space for PC DIY whose system architecture and implementation are detailed. To evaluate the usability of the proposed system, a questionnaire is given to twenty-six graduate students after their hands-on experience with the prototype. Results of the questionnaire show the proposed AR learning space for PC DIY offers students a motivating, pleasant, and satisfying learning experience. Limitation, conclusion and future studies are given.
