RESEACHERS BUILT A 40-PLANE MULTIFOCAL DISPLAY WITH JUST ONE SCREEN
Researchers from Carnegie Mellon University built a multifocal display with 40 unique planes. The system involves a 1600Hz screen and a focus-tunable lens.All VR headsets on the market today are fixed focus. Each eye is given a separate image, but the screen is focused at a fixed distance from the lenses. This means that your eyes point (verge) towards the virtual distance to what you’re looking at, but focus (accommodate) to the fixed focal length of the display. This is called the vergence-accommodation conflict. It causes eye strain and headaches and also makes near objects look blurry.One approach to solving this is to build a headset with multiple screens layered, with each at a different focus length. This is called a multifocal display. The problem however is that to truly solve the vergence-accommodation conflict, the reseachers researchers that 41 focal planes would be needed. If this were done with hardware it would massively increase cost and weight to the point of impracticality. READ MORE
