<ul data-eligibleForWebStory="true">Apple is improving its Persona avatars on Vision Pro in VisionOS 26, raising the visual quality significantly.The new Persona system captures detailed facial features, improved skin texture, and realistic motion.The system enhancements extend to the external 'EyeSight' display for better detailing.Concerns arise on how Apple will maintain quality on smaller headsets due to limited space for cameras.As headsets become smaller, angles become sharper, posing challenges for accurate motion mapping and facial tracking.Companies are exploring training algorithms to predict facial motion from extreme angles.Future headset sizes may hinder clear camera views for accurate facial tracking, particularly in goggles-sized devices.Eye-tracking remains a viable option for smaller headsets, offering a better view angle for eye movements.Achieving lifelike avatars in XR communication will necessitate full face-tracking beyond just eye-tracking.The article discusses potential solutions for maintaining avatar quality on smaller headsets.The article explores the challenges and innovations in ensuring high-quality avatars on compact XR devices.
