I'll second this. Among other things, we use Ignition as the UI for an inspection/verification system in our shop generally and, soon, for confirming that a job is ready to move to the next stage. The inspector literally goes around the shop with a tablet checking off each item, or, if they see something that needs following up, making a quick note instead. The people using it report that they would love it if they could just wear a headset and say "complete", "next", "back", or "follow-up" as they go through each individual inspection item, instead of messing with the tablet's buttons and keyboard. I know this is a little more sophisticated than just giving microphone/camera access, but think of the possibilities in the long run.
