The beauty of the design is that the Orion does not change the way the TI-84 operates;
it simply enhances the operation of the calculator for users who have vision impairment.
A math or science instructor does not have to learn anything new in order to operate
the calculator and can, therefore, continue to teach the same math problem to every
student in the same manner.
In an online article in The Atlantic titled "What Your Old Graphing Calculator Says About
Technology," Alexis Madrigal considers the reasons why traditional graphing calculators
are still significant in today's classrooms. One important example he presents is,
