It looks like Apple is planning to include face recognition capabilities in iOS 5.
9 to 5 Mac has discovered several face recognition APIs in iOS 5 beta 4 that was seeded to developers late last week.
9 to 5 Mac reports:
Wired video mirroring was first unleashed on the iPad 2 with iOS 4.3.x, but starting from iOS 5 beta, Mirroring went cables free via AirPlay but had certain limitations and didn’t work in some apps such as FaceTime.
Now starting from iOS 5 beta 3, you can mirror your FaceTime video calls via AirPlay on your Apple TV 2G hooked up to your gigantic TV! Yes you read that right, whenever you’re in a FaceTime call and feel a bit closed in on your iPhone’s small 3.5 inch screen, you can take a huge leap onto your TV via AirPlay Mirroring, isn’t that awesome?!
Apple has also enabled the new AssistiveTouch features in iOS 5 beta 3, in addition to performance improvements, additional location controls, voice roaming toggle, other changes and improvements that we covered earlier.
AssistiveTouch allows you to use your iOS device if you have difficulty touching the screen or if you require an adaptive accessory.
Once you have enabled the AssitiveTouch feature via the Settings app (Settings -> Accessibility -> AssitiveTouch), you can access various functions such as multi-touch gestures, volume buttons etc. via a control panel that can be activated by tapping an overlay button. You can also create custom gestures.
