Some people have experienced headaches while using virtual reality headsets in the past. Stanford researchers are developing a new type of VR display that adapts to differences in how you see the world, reducing headaches and nausea in the process.
The group tested two different hardware options. One relies on focus-tunable liquid lenses. Twisting a dial squeezes the liquid lenses inside the headset to change the screen display even though the lens itself remains in place. The other option involves mechanically moving the display screen back or forth, like adjusting a pair of binoculars. The system also incorporates eye-tracking technology to determine where on the screen the user is looking.
These headsets were tested on numerous participants and found to have improved their viewing experience. More info is available here.
