5. Augmented Reality is a technology
which
• Combines real and virtual imagery
• Is interactive in real time
• Registers the virtual imagery with the real world
[Azuma, 1997]
6. Augmented Reality is a technology
which is of relevance in education because it
• Draws attention - critical in instruction
• Conveys spatial cues directly instead of just visual images
• Is used with hands, and provides sensorimotor feedback
• Provides constructivist environment to enhance learning
• Direct manipulation in comparison with mouse-based computergenerated visualization
[Gagne et al., 1992; Dede, 1995; Shelton, 2004; Schank, P., 2002]
8. E Learning
refers to training initiatives which provide learning material,
course communications, and the delivery of course content electronically
through technology mediation.
[Eddy and Tannenbaum, 2003]
9. E Learning draws our attention because..
•
•
•
•
Increased flexibility and convenience in taking courses
Time and place constraints are removed
Greater grasp over the learning process
Greater control in the hands of the learner over paceflow and interactions
[Wydra, F.T.,1980]
10. If you dont believe us..
• Organizations are currently spending over $16billion on technology-based
training [Industry training report, 2006]
• Millions of students are enrolling in web-based courses [Wirt et al.,2004]
•
E-learning market has a growth rate of 35.6% [Wu et al., 2006]
14. • Identify scope of Augmented Reality
in E Learning and in our subject of
interest - Solid State Chemistry
• Develop an AR based E Learning
solution for a specific section in Solid
State Chemistry
• Conduct a comparative study of the
developed solution with conventional
e learning solutions available as of today

17. • Spatial ability is a prerequisite to the
understanding of three-dimensional
arrangements of molecules [Hyde et al. 1995]
• Spatial ability leads to a deeper understanding
of many chemical concepts [Pribyl and Bodner
1987; Yang et al. 2003]
• Students often have problems in generating a
spatial model from a two-dimensional illustration
[Garnett et al.1995; Wu and Shah 2004]

workbench consisting of a table and a
rear-projection screen. Users interact with
models in this virtual environment using a
booklet and a cube. Each page in the
booklet is used to identify an element of
the periodic table. [Morten. F, Benedikt M]

53. • Virtual buttons are developer-defined
rectangular regions on image targets that
trigger an event when touched or occluded in
the camera view.
• For example, in the sample picture, pointing the
hand or touching the rectangular region triggers
an action associated with the button.
• Such buttons provide an intuitive means of
interaction since the users are directly using the
content (on paper / surface) to navigate / as a
button rather than on screen buttons
Department of Design, IIT Guwahati

55. • The graphical user interface of Augmented
Reality Apps are primarily simple because a
major chunk of screen space is dedicated to the
camera for easy viewing.
• In this project, we have used two GUI buttons to
allow users to navigate / toggle between
different views of the same 3D model.
• An additional ‘mute’ GUI button has also been
added to control audio feedback.

Wow factor and non familiarity with technology major
driving force behind initial feedback.
•
Some students pointed that they would have liked to see
rotation and movement through touch gestures on phone
as well.
•
One student wanted content to be broken down to even
smaller steps (atom joining atom instead of layer joining
layer)

• To learn making very basic augmented reality
applications would’t need more than a week
• Finding right tool for such an app can take more
than one month
• Unity 3d with Vuforia SDK
• Basic C Sharp
• More features you add, more complex would be
the code structure
• Removing bugs takes much much more time than
making the application
