The remainder of this paper describes three instances of AR
applications in language learning using the modified sample
programs stated in section II. All AR applications were
created by the author who is a university teacher and
inexperienced programmers who are university students. The
first two applications use multiple AR markers tied to noun
words and verb words. The first two applications use multiple
AR markers tied to noun words and verb words. Each card
with an AR marker is overlayed with a static or animated 3D
model that expresses a noun or verb word. The third
application can switch overlayed 3D models for the same
marker by typing keys. Therefore, through the third
application, we are able to learn multiple languages using
single set of AR markers.
