Although quality of display devices is good right now, most textbooks are still printed on papers. At the same time, most learning support and e-learning courseware are built with the assumption that the student only read information displayed on the screen. In this paper, we present an environment that provides learning support via computers, digital devices and network when a student studies a course by reading paper textbooks with a digital pen. The learning support is organized based on the knowledge unit of the location positioning by the digital pen in the textbook. The support includes term explanation, related discussions, underline, and annotation. These studying actions and results on papers will be stored in the computer as well for later use. Initial experiment result on using the system shows that students feel beneficial to their study.
