Plenty of hay has been made over which apps and cell phones track our movements, but so far it has been difficult to accurately determine where we're going next -- people can be unpredictable, after all, and make dinner plans at random new places on a whim. In that case, what's a prediction algorithm to do?
Most cell phones are pretty good at auto-correcting the errant spelling and punctuation that can ensue when you’re typing while furious, or sad, or gleeful. But what if the messages you’re sending could also convey those emotions embedded in your words? RIM filed a patent for just such a messaging system, which can determine the emotional context of a text in a way that goes beyond the little :-) we all know.
