Discussion Questions
The authors present a large number of sample applications that utilize their system.
Out of the three broad categories (Mobile Content Exchange, Education, Games),
which ones stood out to you?
In the paper, the authors state that the technologies used in SideBySide are
commercially available, and can be assembled in a cost-efficient manner. They also say
that the technology could be feasibly deployed in around 2-4 years ago. Given that the
paper came out in 2011, what do you think is the reason why this technology hasn't
appeared to gain significant traction in the handheld market?
