Apple describes a new user interface that would highlight any words or phrases in a message that have been siphoned through autocorrect. The system wouldn't be advanced enough to reveal the specifically intentioned words the sender meant, but at least give the receiver a heads up about which parts of the text were corrected.
Parts of the patent reveal iterations of the idea that can streamline the clarification process, as well. For example, a description of the sender-side user interface includes a prompt that pops up -- after a user taps on the autocorrected word -- with an option to "Send clarification" to the receiver. The canned message fills out the phrase, "I sent [wrong word], but I meant [correct word]." If they want a complete do-over, the user could also just opt to re-send the entire message.
On the receiver-side user interface, if the sender isn't opting to fix the issue themselves, the other person can "Request clarification" by tapping on the highlighted autocorrect word or phrase. The automated message is similar to the previous sender-side phrase, asking "You sent [wrong word]. What did you mean?"
If implemented in a future version of iOS, the autocorrect highlight patent could be similar to the way iOS currently underscores vague references to dates and times when users send and receive text messages. Apple's new patent could be slightly more helpful for most users than that feature, however, especially given the speed with which iPhone users have grown accustomed to texting on the device, and how frustrating it can be to realize autocorrect interfered with your message.
Like most patents, it's still advised to be wary of how long it'll take Apple to implement the autocorrect notification system into iOS, if it ever will. Still, it's easy to see how useful and streamlined such a feature could be, without completely taking out much of the humorous -- and sometimes awkward -- mishaps for which autocorrect has become famous.
