Apple introduces gesture-based video reactions in iOS 18 FaceTime

Apple's iOS 18 enhances FaceTime with gesture-based video reactions, allowing users to trigger 3D animations during calls. This feature works on iPhone 12 and newer models, even if other participants are using different devices. Users can activate eight different effects using specific hand gestures, such as thumbs up for a like or a heart shape for floating hearts. The gestures require hands to be a few inches from the face for accurate recognition. FaceTime gestures are also compatible with supported iPads and Macs. All participants can see the reactions, but only those with compatible Apple devices can use gestures to respond.
