Hand tracking is a significant feature discussed in several sessions at WWDC 2024. It allows for precise and immersive interactions in various applications, particularly in spatial computing and web experiences.

  1. WebXR and Hand Tracking: In the session "Build immersive web experiences with WebXR," hand tracking is available as tracked pointer inputs. This feature allows developers to create experiences that combine hand tracking with natural input, such as gaze and pinch, to interact with virtual content. Hand tracking is particularly useful for precise, close-up interactions, although it can be challenging for ranged actions. Build immersive web experiences with WebXR (02:01)

  2. ARKit and Hand Tracking: The session "Create enhanced spatial computing experiences with ARKit" highlights advancements in hand tracking, which is a primary means of input on platforms like visionOS. The hand tracking provider now delivers data at display rate, reducing latency and improving the smoothness of interactions. This is especially beneficial when using devices like Apple Vision Pro.
