Stanford University engineers have created a prototype for a significantly lighter virtual reality headset, weighing less than 2.5 ounces. This marks a considerable reduction in weight compared to many current VR devices. The headset achieves this lightweight design by employing pancake optics and a newly developed polarization-based optical element that serves as its display. This innovative display technology is designed to produce a nearly holographic visual experience, aiming for highly realistic 3D imagery. Researchers believe this breakthrough in weight reduction could lead to greater user comfort, enabling longer and more immersive VR sessions. The development is seen as a promising step toward making VR technology more practical and accessible for a wider range of applications, though it is currently a research prototype and not yet commercially available.
