In this paper, I present a multifunction reminder platform that is dedicated to an educational environment. I consider the reminder as a two-dimensional function, i.e. depending on two variables, time and space. It automatically produces alarms with notifications whenever these variables take specific values. In other words, when a student approaches an educational or administrative location based on the GPS geo coordinates. The two-dimensional function reminder helps a student to better manage time and avoid delays in accomplishing tasks. I identified several educational uses for the reminder pertaining to the everyday life of a student. The reminder function is demonstrated on the library case study. © 2018 IEEE.
