In this paper, we propose an education support system that offers two functions: attendance management and advance notification. Attendance management is paramount in the field of education as the attendance of a large number of students needs to be accurately checked in a short time. The proposed system uses Wi-Fi indoor positioning to quickly and accurately determine a student’s indoor location. This system can manage attendance as well as late entries and early departures. Advance notification function prompts students to move from their current location to their destination. The proposed system uses a user’s physical activity and indoor position. This system measures the travel time between classrooms using the user’s smartphone. Based on the collected travel time and the current position of the student, a notification of the start of travel is made at an optimal advance notification time. This prevents students from being late for lectures.
