We proposed a novel Content Aware and Power
Efficient approach of educational multimedia adaptation
for mobile learning. The fundamental idea is that
educational effectiveness of every segment of a learning
multimedia should be considered in power-saving
adaptation process. Our proposed approach adapts entire
multimedia resource on fragment by fragment basis
considering presentation constraints on each fragment,
offering many advantages over existing adaptation
techniques that deliver adapted multimedia in a single
uniform quality. We ensure that maximum possible
battery efficiency is achievable without negatively
affecting the learning process. We present a conceptual
framework and an abstract metadata model that guides
the implementation of our power saving educational
multimedia adaptation. We also briefly discuss our proof
of concept prototype system.
