Crew on the USS Coronado are trialing Vocera's Wi-Fi badges: I know that hospitals and other organizations are already using the system from Vocera but I just don't see it. Depending on what the Navy wants to use them for, this sounds like a recipe for disaster. What if it's noisy and the badge can't pick up the user's command to dial someone? I'm still very cautious about anything that uses voice recognition because I've yet to see anything that works well.
