Abstract:

We propose a new digital signage (DS for short) for learning material delivery on university campus. The DS identifies student viewers using a high-powered RFID reader and delivers learning materials suitable for not only one student but also some students based on student friendship. The student friendship can be estimated from the viewing data of learning materials. This is because students often spend the break time together with friends. If one of the friends stops to view a learning material being delivered, all of them will infectiously do it. Therefore, a learning material that they are interested commonly in should be delivered. Also, if a learning material is delivered based on potential friendship, unacquainted viewer students can be united and form friendship as learning community. For example, two students who viewed the same learning material at different times and places before can have friendship in terms of interest in the learning material. New student friendship formed through face-to-face contact in front of the DS (large-size public display) can motivate students to learn together.

There are two types of the learning material delivery focusing on student friendship. One is based on existing friendship. Another is based on potential friendship. The fundamental procedure of two kinds of the learning material delivery based on student friendship (existing friendship and potential friendship) is shown as follows:
i. The DS identifies students who enter the viewable area (in front of the DS) by using a high-powered RFID reader.
ii. The DS sends the identified students' IDs to the server that stores the viewing data.
iii. The server receives the IDs and retrieves their existing/potential friendship.
iv. The server selects the learning material that they are interested commonly in and they have not viewed from the beginning to the end.
v. The server sends the selected learning material's ID to the DS.
vi. The DS receives the ID and presents the corresponding learning material from the beginning in an interruption manner.
