[NSRCA-discussion] Virtual Caller for iOS

[Lance]

Ok this helps a lot . By "headphone button" I assume you mean "calling enabled ". I am now able to change the starting orientation and then turn off/on calling enabled to rest the neutral point. I think you are successfully calculating rotational angles because it seems I can establish a neutral point with the phone not necessarily flat or vertical but somewhere in between. 
I had more success this time but found that it seems pretty sensitive to returning to that initial pose. Returning to a position close to the original can lead to missed or extra advances to the "next" maneuver. So the sensitivity request is really two sensitivities. One for how much change determines a "next" event and another for what is considered a successful return to neutral pose. Possibly consider resetting the neutral orientation every time it successfully returns to neutral so the delta for a change event is always measured from "zero"

This is a great platform and pulling sequences from a server is good design. These polish suggestions will make it fit more pilot personal styles more easily. Thanks

>> Nice job! I don't fly with a tray but assumed I could slide the phone into a breast pocket (vertical default orientation) and tilt my body to advance to the next maneuver but it's not working well. I've tried all the tilt axes but the caller just runs away calling maneuvers too fast. I suspect you assume the default orientation is that the phone will be flat horizontal or close to it so its confused when the phone is vertical. 
>> Maybe when the user selects their roll axis you can sample the current orientation to set the default position?
>> Also it would be nice to have a slider to adjust the sensitivity. A very still pilot could use just a small tilt to indicate whereas a pilot using more body English needs less sensitivity.

You will need to be on the network the first time you run so it can download the sequences from the cloud.
