Making use of Multimedia with Mobile DevicesZak Mensah / JISC Digital Media

@zakmensah / @jiscdigital

Context-aware mobile learning means that

learners at a specific location or venue, for

example standing in front of a painting or

tree, can automatically access progressively

more background material in the form of audio,

video, quizzes and interactions to enrich their

understanding and experience of the place or

event.
