they have those necklace mp3 players. this is just the next step.
you wear a net connected voice controlled computer in a necklace form-factor. i think all the tech pieces off the shelf. they just need to be put together. you'll also look less idiotic than those people with bluetooth headsets.
a string, a gumstix, some software, some custom software. $150
here are some examples..
billy: hey saskia (choose a cool sounding name)
saskia: yeah billy
billy: REMEMBER that i'm out of detergent and baking soda
saskia: got it
billy: hey saskia
saskia: yeah billy
billy: what's the DEFINITIONOF cornucopia
saskia: a goat's horn overflowing with fruit, flowers, and grain, signifying prosperity.
billy: hey saskia
saskia: yeah billy
billy: how's my EBAYBID doing?
saskia: ebay sucks
as you might of guessed. to make it simple, cuz natural language programming is difficult (even with an abrash.) the caps are the commands that saskia is scanning for.
the best one is..
billy: hey saskia
saskia: yeah billy
billy: what TIMEISIT?
saskia: it's 5:53am
after all.. all technology does is replace older technology with something more complicated and more expensive.
