OK, had a chance to try the apps (iOS and Android) at the field today with high winds some definite recognition issues for me to deal with... Also, some definite usability issues to consider around accidental changes of the schedule being used, speech recognition starting too early, etc.

So... here's my thinking:

1. Make schedule choice be on a separate screen from calling mode, so you choose the schedule, then hit a button to go to calling mode. You click "start calling" (instead of saying it) and the screen locks so you can't hit any buttons accidentally. When you say "done" the screen unlocks and you flip back to the schedule selection screen. I'm thinking it will listen ONLY for "TAKING OFF!" to be yelled before listening for anything else, that way you can get set up, call "coming out", etc. that you may need to do to declare intent at the field before you take off.

2. "I didn't understand what you said" takes too long to say, I'm going to change it to "Pardon?" and I think I'll give you an option that if it heard *anything* other than back please or repeat that it will go next, as that's the most likely intent...

Anything else folks?
