Example Concept: Hand tracking accuracy in AR headsets is influenced by the integration of high-resolution cameras and advanced computer vision algorithms. Devices like the HoloLens 2 use time-of-flight sensors to capture depth information, while others, such as the Magic Leap 2, rely on a combination of RGB and IR cameras to enhance tracking fidelity. The software stack, including machine learning models for gesture recognition, also significantly impacts the overall tracking performance.
