The CAEE implementation is quite real or lifelike when
compared to the original experiment additionally the same
functionality (pulsating LED) is obtained from the CAEE
implementation. The 2D photographic mock-up can beprinted using a low cost color printer at scales of 1:1 or
even lower. The same instructional material is used for
both versions of the experiment, in the CAEE implementation
connection of components is archived by touching;
this represents a minimal change in instructional material.
During practical testing, it was quickly noted that the
CAEE implementation also tracks successfully the real
Seeeduino board (not just its photographic mock-up) even
from different angles of view, distances and resolution.Asthis implies, the CAEE component may be used as an aid
during practical laboratory sessions (on the real board), in
addition to group collaborative work involving multiple
learners standing around either the photographic mock-up
or the real board. In the CAEE implementation, although
it is possible to implement a drag-and-drop motion for
attaching the components, a simple touch action is used in
a bid to focus on showing the correct connection of components.
Mobile augmented reality is increasingly being used
mainly for visualization especially in the medical fields.
The CAEE concept is one of the first (if not the first) use
of this technology for experiments. A similar independent
work is documented in the “Augmented Reality Breadboarding”
[10]. Unlike in most virtual reality implementations,
the CAEE concept is about simulating the experimental
procedures/outcomes and not the simulation of
devices/components. Unlike remote laboratories, a central
experimental facility is not involved and the CAEE implementation
may be used on mobile devices already
owned by the learners, even in the comfort of their homes
