Via Dintz and ThinkGeek comes the real world baby translator.  This one doesn’t speak in the voice of Danny DeVito, it just shows you whether the infant is Hungry, Bored, Annoyed, Sleepy, or Stressed. (That’s the symbol for “Annoyed” on the display image.)  The read out on the front, for lack of anything better to do, also displays the current temperature and humidity.

Maybe this thing could be tremendously useful to on-the-go 21st century parents, but I’m skeptical. What is the difference – for an infant – between “Annoyed” and “Stressed”?  What qualifies as “Bored” for a person with extremely limited motor control and little to no ability to understand speech?  It will cost you $100 and most of your remaining dignity.
