What does the screen calibration do on the screen settings menu? iFly 740. My screen does not easily swipe.

The iFly 7xx devices use what is called a "resistive" touch screen, rather than the "capacitive" touch screen typically used on current phones and tablet devices. At the time those devices were released, resistive screens generated a much easier-to-read image in direct sunlight compared to the capacitive displays available.
The tradeoff is that the digitizer (the part of the display that registers touches) would "drift" over time, such that where you actually touched the screen would not align with where the digitizer thought you touched it. This behavior does not occur with capacitive touch screens.
Calibration is a method to try to realign the digitizer such that it picks up your touches where it is supposed to.
Note that it's possible for digitizers to drift enough that they can no longer be successfully recalibrated. Depending on the way the device is used, this might cause no impact (if the affected part of the screen is not used for touch inputs), might cause a minor annoyance (if the user can compensate by intentionally tapping a spot appropriately offset from where he wants the touch to be registered), or might render the device essentially unusable (if there is no way to tap in a place where the digitizer will record a touch in a spot necessary to effect some necessary app function).
Calibration does not have anything to do with how hard you have to press down on the screen for a touch to be registered, so if that is your problem, this is not the solution.
Have you tried using something hard but not too pointy as a stylus to tap the screen, instead of using your finger? Many users reported that a Bic ballpoint pencap was a handy and inexpensive workaround option when they had trouble getting the display to register a finger press.
Just be careful not to press too hard with a pointed stylus, even a rounded one like a Bic pencap, as it is possible to leave permanent creases / traces in the thin material, or even puncture it in extreme cases.
