Recently Google/Motorola announced this:http://www.digitaltrends.com/mobile/motorola-google-patents-throat-tattoo-microphone/
A throat mic, or subaudible microphone. Which would be essentially a 'neck tatoo' that would pick up your voice more easily than the current system, which often has to filter out ambient background noises.
One caveat. they included galvanic response. Which, briefly, means tension, stress, and anxiety.
A little band that helps you connect with, you. Just through a remote device, wireless.
That's right, on your wrist a personal device for monitoring your agility, stress and heart rate. Tie in an app to monitor that, a you have a great little tool to help .... whom?
Both of these devices and applications seem to have a troubling feature. The information, its not for the user - its for someone else.
Are you lying? Attracted? Homicidal?
What about at your place of work? Are you not challenged enough (target heart rate and galvanic skin results indicate that you are slacking off. perhaps overworked? or just not _fit_ting in?
Its a new concept in intrusions into even unspoken matters of privacy, one we'll need laws to protect, and proactively.
