Apple improved facial recognition in iLife 2011's iPhoto while adding new slideshow features and themes. It now appears that Apple is already working on the next round of improvements by adding more advanced facial recognition features to iPhoto for home slideshows or work presentations. Interestingly, the patent shows us that this iPhoto feature is designed to work on iOS devices. Another Apple patent published today discusses a new handheld device latch that will make it easier to access batteries. Apple is mum as to which handheld device the latch is for. And lastly, there's news of a third party developer working on a tripod for iPod and other iOS devices that could help us take steadier videos and photos. That was only a matter of time, though it probably won't be ready in time for this summer.
