Prototype Digital Signage System for Learning Material Delivery Focusing on Student Friendship

A digital signage system to deliver learning materials on a university campus is described. The proposed system identifies student viewers using a high-powered radio-frequency identification reader and delivers learning materials that are suita-ble for multiple students based on existing and potential friendships, which can be estimated from the learning material viewing data. The delivery of learning ma-terial can reinforce existing student friendships and identify potential friendships (i.e., unite unacquainted students who can potentially form a learning communi-ty). A preliminary experiment revealed that the existing-friendship estimation is currently inaccurate and unsuitable.
